| Freescale Semiconductor Advance Information Document Number: MC33882 Rev. 5.0, 10/2006 Six-Output Low-Side Switch with SPI and Parallel Input Control The 33882 is a smart six-output low-side switch able to control system loads up to 1.0 A. The six outputs can be controlled via both serial peripheral interface (SPI) and parallel input control, making the device attractive for fault-tolerant system applications. There are two additional 30 mA low-side switches with SPI diagnostic reporting (with parallel input control only). The 33882 is designed to interface directly with industry-standard microcontrollers via SPI to control both inductive and incandescent loads. Outputs are configured as open-drain power MOSFETs incorporating internal dynamic clamping and current limiting. The device has multiple monitoring and protection features, including low standby current, fault status reporting, internal 52 V clamp on each output, output-specific diagnostics, and protective shutdown. In addition, it has a mode select pin affording a dual means of input control.

The shorted output is turned ON during tSS to retry and check if the short has cleared. The shorted output is in current limit during tSS. The tSS is measured from the start of current limit to the end of current limit. The Short Fault Refresh Time is the waiting period between tSS retry signals. The shorted output is disabled during this refresh time. The tREF is measured from the end of current limit to the start of current limit. The tOS(OFF) is measured from the time the faulted output is turned OFF until the fault bit is available to be loaded into the internal fault register. To guarantee a fault is reported on SO, the falling edge of CS must occur at least 100 s after the faulted output is off. The tOS(ON) is measured from the time the faulted output is turned ON until the fault bit is available to be loaded into the internal fault register. To guarantee a fault is reported on SO, the falling edge of CS must occur at least 12 ms after the faulted output is ON. Percent Output Short Fault ON Duty Cycle is defined as (tSS) / (tREF) x 100.

There are also two lowpower (30 mA) low-side switches with SPI diagnostic feedback, but parallel-only input control. The 33882 incorporates SMARTMOS technology with CMOS logic, bipolar / MOS analog circuitry, and DMOS power MOSFETs. Designed to interface directly with a microcontroller, it controls inductive or incandescent loads. Each output is configured as an open drain transistor with dynamic clamping. FUNCTIONAL PIN DESCRIPTION VPWR Pin The VPWR pin is connected to battery voltage. This supply is provided for overvoltage shutdown protection and for added gate drive capabilities. A decoupling capacitor is required from VPWR to ground. IN0 & IN1, IN2 & IN3, and IN4 & IN5 Pins These input pins control two output channels each when the MODE pin is pulled high: IN0 & IN1 controls OUT0 and OUT1, IN2 & IN3 controls OUT2 and OUT3, while IN4 & IN5 controls OUT4 and OUT5. These pins may be connected to PWM outputs of the control IC and pulled high or pulled low to control output channel states while the MODE pin is high. The states of these pins are ignored during normal operation (MODE pin low) and override the normal inputs (serial or parallel) when the MODE pin is high. These pins have internal active 25 A pull-downs. SI Pin The Serial Input pin is connected to the SPI Serial Data Output pin of the control IC from where it receives output command data. This input has an internal active 25 A pulldown and requires CMOS logic levels. The serial data transmitted on this line is an 8- or 16-bit control command sent MSB first, controlling the six output channels. Bits A5 through A0 control channels 5 through 0, respectively. Bits A6 and A7 enable ON open load fault detection on channels 5 through 0. The control IC will ensure that data is available on the rising edge of SCLK. Each channel has its serial control bit high with its parallel input to determine its state. SCLK Pin The SCLK pin of the control IC is a bit (shift) clock for the SPI port. It transitions one time per bit transferred when in operation. It is idle between command transfers. It is 50% duty cycle and has CMOS levels. This signal is used to shift data to and from the device. For proper fault reporting operation, the SCLK input must be low when CS transitions from high to low. MODE Pin The MODE pin is connected to the MODE pin of the control IC. This pin has an internal active 25 A pull-up. When pulled high, the MODE pin does the following: * Disables all serial control of the outputs while still reading any serial input commands. * Disables parallel inputs IN0, IN1, IN2, IN3, IN4, and IN5 control of the outputs. * Selects IN0 & IN1, IN2 & IN3, and IN4 & IN5 input pins for control of OUT0 and OUT1, OUT2 and OUT3, OUT4 and OUT5, respectively. * Turns off OUT6 and OUT7. * Tri-states the SO pin. IN0 to IN7 Pins These are parallel input pins connected to output pins of the control IC. Each parallel input is logic high with the corresponding SPI control bit to control each output channel. These pins have internal 25 A active pull-downs. OUT0 to OUT7 Pins Each pin is one channel's low-side switch output. OUT0 to OUT5 are actively clamped to handle inductive loads. CS Pin The CS pin is connected to a chip select output of the control IC. The control IC controls which device is addressed by pulling the CS pin of the desired device low, enabling the SPI communication with the device, while other devices on the serial link keep their serial outputs tri-stated. This input has an internal active 25 A pull-up and requires CMOS logic levels. SO Pin The Serial Output pin is connected to the SPI Serial Data Input pin of the control IC or to the SI pin of the next device in a daisy chain. This output will remain tri-stated unless the device is selected by a low CS pin or the MODE pin goes low. The output signal generated will have CMOS logic levels and the output data will transition on the falling edges of SCLK. The serial output data provides fault information for each output and is returned MSB first when the device is addressed. Fault bit assignments for return data are as follows: MSB-0 through MSB-7 are output fault bits for OUT7 to OUT0, respectively. In 8-bit SPI mode, under normal 33882 Analog Integrated Circuit Device Data Freescale Semiconductor 17 FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION conditions, the SO pin (not daisy chained) returns all 0s, representing no faults. If a fault is present, a 1 is returned for the appropriate bit. In 16-bit SPI mode, sending a double command byte will provide a command verification byte following the fault status byte returned from the SO pin (nondaisy chained). With the MODE pin high, the serial output pin tri-states. If nothing is connected to the SO pin except an external 10 k pull-up resistor, data is read as all 1s by the control IC. VDD Pin This pin is connected to the 5.0 V power supply of the system. A decoupling capacitor is required from VDD to ground. PERFORMANCE FEATURES Normal Operation OUT0 to OUT7 are independent during normal operation. OUT0 to OUT5 may be driven serially or by their parallel input pins. OUT6 and OUT7 can only be controlled by their parallel input pins. Device operation is considered normal only if the following conditions apply: * VPWR of 5.5 V to 24 V and VDD voltage of 4.75 V to 5.25 V. * Junction temperatures less than 150C. * For each output, drain voltage exceeds the Open Load OFF Detection Voltage, specified in the specification table, while the output is OFF. For open load detection, an open condition existing for less than the Open Load Detection time, specified in the specification table, is not considered a fault nor is it reported to the fault status register. * The MODE pin is held at the logic low level, keeping the serial channel / parallel input pins in control of the eight outputs. Serial / Parallel Input Control Input control is accomplished by the serial control byte sent via the SPI port from the control IC or by the parallel control pins for each channel. For channels 0 to 5 with serial and parallel control the output state is determined by the OR of the serial bit and the parallel input pin state. Serial communication is initiated by a low state on the CS pin and timed by the SCLK signal. After CS switches low, the IC initiates eight or 16 clock pulses with the control bits being available on the SI pin at the rising edge of SCLK. The bits are transferred in descending bit-significant order. Any fault or MODE indications on bits returned are logic [1]s. The last six bits are the command signals to the six outputs. Upon completion of the serial communication the CS pin will switch high. This terminates the communication with the slave device and loads the control bits just received to the output channels. Upon device power-up, the serial register is cleared. In the application for non-daisy chain configurations, the number of SPI devices available to be driven by the SO pin is limited to eight devices. Serial Status Output Serial output information sent on the SPI port is a check on the fault status of each output channel as well as a check for MODE initiation. Serial command verification is also possible. SO Pin Operation The SO pin provides SPI status, allowing daisy chaining. The status bits returned to the IC are the fault register bits with logic [1]s indicating a fault on the designated output or MODE if all bits return logic [1] (with a 10 k pull-up resistor on the SO pin). A command verification is possible if the SPI mode is switched to 16 bits. The first byte (8 bits) returned would be the fault status, while the second byte returned would be the first byte sent feeding through the 33882 IC. The second command byte sent would be latched into the 33882 IC. The CS pin switching low indicates the device is selected for serial communication with the IC. Once CS switches low, the fault status register cannot receive new fault information and serial communication begins. As the control bits are clocked from the IC MSB first, they are received on rising SCLK edges at the SI pin. The fault status bits transition on the SO pin on falling SCLK edges and are sampled on rising SCLK edges at the input pin of the IC SPI device. When the command bit transmissions for serial communication are complete, the CS pin is switched high. This terminates communication with the device. The SO pin tri-states, the fault status register is opened to accept new fault information, and the transmitted command data is loaded to the outputs. At the same time, the IC can read the status byte it received. Daisy Chain Operation (Only Possible with SO Pin) Daisy chain configurations can be used with the SO pin to save CS outputs on the IC. Clocking and pin operations are as defined in the SO Pin Operation paragraph. For daisy chaining two 8-bit devices, a 16-bit SPI command is sent, the first command byte for the second daisy chain device and the second command byte for the first daisy chain device. A command verification is possible if the SPI mode is switched to 32 bits. The first word sent is command verification data fed through the two 33882 ICs. Data returned in the 32 bits is the two fault status bytes, followed by the first word sent. Bits sent out are sampled on rising SCLK edges at the input pin of the next IC in the daisy chain. Note Because SO pins of the 33882 ICs are tri-stated, any device receiving its SPI data from a previous 33882 IC SO pin in a daisy chain will not receive data if the MODE pin is low. This prohibits setting SPI-controlled channels ON with a SPI command while the MODE pin is low. Therefore, all channels remain OFF when the MODE pin changes from low to high at vehicle power-up. 33882 18 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION MODE Operation During normal operation output channels are controlled by either the Serial Input control bits or the parallel input pins. If the MODE pin is pulled high: * Serial input control is disabled. * Parallel input pins IN0 to IN5 are ignored. * The SO pin is tri-stated. OUT0 and OUT1, OUT2 and OUT3, and OUT4 and OUT5 are controlled by the IN0 & IN1, IN2 & IN3, and IN4 & IN5 pins, respectively. When a 10 k pull-up resistor is used, a logic high on the MODE pin or an open serial output pin is flagged by the SPI when all bits are returned as logic [1]s. Although a logic high on the MODE pin disables serial control of outputs, data can still be clocked into the serial input register. This allows programming of a desired state for the outputs taking effect only when the MODE pin returns to a logic low. For applications using the SO pin, daisy chaining is permitted, but if the MODE pin is high, writing to other than the first IC in a daisy chain is not possible because the serial outputs are tri-stated. Output Drivers The high-power OUT0 to OUT5 outputs are active clamped, low-side switches driving 1.0 A typical or less loads. The low-power OUT6 and OUT7 outputs are unclamped lowside switches driving 30 mA typical or less loads. All outputs are individually protected from short circuit or short-to-battery conditions and transient voltages. The outputs are also protected by short circuit device shutdown. Each output individually detects and reports open load /short-to-ground and short circuit /short-to-battery faults. Fault Sense / Protection Circuitry Each output channel individually detects shorted loads / short-to-battery while the output is ON and open load /shortto-ground while the output is OFF. OUT0 to OUT5 may also be programmed via SPI bits 6 and 7 to detect open loads and shorts-to-ground while the output is ON. Whenever a short or open fault condition is present on a particular output channel, its fault bit in the internal fault register indicates the fault with a logic [1]. When a fault ends, its fault bit remains set until the SPI register is read, then it returns to a logic [0], indicating a normal condition. When the CS pin is pulled low for serial communication, the fault bits in the internal fault register latch, preventing erroneous status transmissions and the forthcoming communication reports this latched fault status. The SO pin serial output data for 8-bit SPI mode are the fault status register bits. For 16-bit SPI mode and SO pin (non-daisy chained) use, a transmitted double command provides the fault byte followed by the first byte of the double command, becoming a command verification. The status is sent back to the IC for fault monitoring. Diagnostic interpretation of the following fault types can be accomplished using the procedure described in the paragraph entitled Extensive Fault Diagnostics, page 20: * Communication error * Open load /short-to-ground * Short-to-battery or short circuit When serial communication is ended, the CS pin returns high, opening the fault status register to new fault information and tri-stating the SO pin. Two fault conditions initiate protective action by the device: * A short circuit or short-to-battery on a particular output will cause that output to go into a low duty cycle operation until the fault condition is removed or the input to that channel turns OFF. * A short circuit condition causes all channels to shut down, ignoring serial and parallel inputs to the device. To be detected and reported as a fault, a fault condition must last a specified time (fault sense time or fault mask time). This prevents any normal switching transients from causing inadvertent fault status indications. Fault status information should be ignored for VBAT levels outside the 9.0 V to 17 V range. The fault reporting may appear to function properly but may not be 100 percent reliable. Short Circuit /Short-to-Battery Sensing and Protection When an output is turned ON, if the drain current limit is reached, the current remains at the limit until the short circuit sense time, tSS, has elapsed. At this time, the affected output will shut down and its fault status bit switches to a logic [1]. The output goes into a low duty cycle operation as long as the short circuit condition exists and the input to that channel is ON. This duty cycle is defined by the sense and refresh times. If a short occurs after the output is ON, the fault sense time indicates the fault and enters the low duty cycle mode at much less than t SS. The duty cycle is low enough to keep the driver from exceeding its thermal capabilities. When the short is removed, the driver resumes normal operation at the next retry, but the fault status bit does not return to a normal logic [0] state until it is read from the SPI. When the CS pin of this device is pulled low, the fault status bits are latched, after which any new fault information is not a part of this serial communication event. The low duty cycle operation for a short circuit condition is required to protect the output. It is possible to override this duty cycle if the input signal (parallel or SPI) turns the channel ON and OFF faster than 10 kHz. For this reason control signals should not exceed this frequency. Open Load / Short-to-Ground While Off Sensing If the drain voltage falls below the Open Load OFF Detection Voltage at turn OFF for a period of time exceeding the Open Load Sense Time, the fault status bit for this output switches to a logic [1]. If a drain voltage falls below the Open Load OFF Detection Voltage threshold when the output has been OFF, a fault is indicated with a delay much less than the Open Load Sense Time. When the fault is removed, normal operation resumes and the fault status bit will return to a normal logic [0] state. 33882 Analog Integrated Circuit Device Data Freescale Semiconductor 19 FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION When the CS pin of this device is pulled low, the fault status bits are latched, after which any new fault information is not part of this serial communication event. Overvoltage Sensing and Protection When VPWR exceeds the Overvoltage Shutdown Threshold, all channels are shut down. Serial input data and parallel inputs are ignored. The device resumes normal operation when the VPWR voltage drops below the Overvoltage Shutdown Hysteresis voltage. During overvoltage shutdown, some faults may appear to report accurately; however, fault sensing operation is only guaranteed for battery voltage levels from 9.0 V to 17 V. Fault Status Monitoring Requirements for Serially Controlled Outputs, SO Pin Fault monitoring over the serial channel by the IC requires a minimal amount of overhead for normal operation. Each status byte received consists of all logic [0]s when faults are not present. If any logic [1]s are returned, a communication error occurred, an output fault occurred, or the MODE pin has been set low. Upon receiving any logic [1] bits, the IC must resend the last command, verifying the returned logic [1]s, or correct any communication error. A 16-bit SPI transmission with a double command byte to this 8-bit device allows verification of the command (second byte returned) in addition to the fault byte (first byte returned). The command (second) byte returned should mirror the bits sent unless a communication error occurred, in which case the command resent should accomplish the correction. If the returned logic [1] validates, it may indicate a MODE pin high or a confirmed output fault. If it was a confirmed output fault, extensive diagnostics could be performed, determining the fault type, especially if vehicle service is being performed. If all bits return high and verify such, the IC must verify sending a logic low to the MODE pin. It should then resend the command, verifying the MODE pin is at a logic low level, allowing resumption of a normal operation. If all logic [1]s are again returned, there is an open SO line, an open MODE line, or the SPI is not functioning. If the fault does not verify on the command resend, normal operation is resumed. The error could be a communication mistake, a momentary output fault, or a fault condition no longer sensed due to switching the state of the output. For the first two cases, normal operation is resumed and the software continues its normal functions. However, in the third case, additional commands are required for extensive diagnosis of the fault type if this information is mandatory. Extensive Fault Diagnostics More extensive diagnosis may be required under the following conditions: * When the fault type of a confirmed fault is desired, the following scenarios are possible: - If MSB-2 to MSB-7 indicates a fault, it is an open load / short-to-ground fault if the output is OFF when - the fault is reported because only open load / shortto-ground sensing remains operable while an output is OFF. If the output is ON when the fault is reported, the fault is a short circuit /short-to-battery if ON open load detection is not enabled via SPI. If ON open load detection is enabled, it must be disabled and the fault status reread. If the fault remains, it is a short circuit / short-to-battery or it is an open load / short-to-ground. If MSB-0 to MSB-2 indicates a fault, it is an open load / short-to-ground fault if the output is OFF when the fault is reported because only open load /shortto-ground sensing remains operable while an output is OFF. - If the output is ON when the fault is reported, the fault is a short circuit /short-to-battery. * When a fault did not confirm on resend, the fault could either be an short circuit /short-to-battery fault, not sensed when turned OFF; an open load /short-to-ground fault, not sensed when turned ON; or a corrected communication error. To determine if it is an output fault condition, the faulted output must be turned back to its previous state with a new command. This command should be sent twice to read the status after the output is latched in this state, thus confirming the fault and reporting it again. Parallel control of outputs is a mode of control, potentially requiring extensive diagnostics if a fault is reported. This is because parallel control signals are completely asynchronous to the serial commands. Status reports for parallel controlled outputs could require additional information exchange in software to: * Avoid status reads when outputs are transitioned, thereby avoiding fault masking times. * Obtain the state of a faulted output for determining fault type (if required). System Actuator Electrical Characteristics (at Room Temperature) All drains should have a 0.01 F filter capacitor connected to ground. Any unused output pin should not be energized. A 20 resistor to the battery is required to prevent false open load reporting. There must also be a maximum of 100 of resistance from VPWR to ground, keeping battery-powered loads OFF when the IC is powered down. However, all loads should be powered by VPWR to protect the device from full transient voltages on the battery voltage. Power-Up The device is insensitive to power sequencing for VPWR and VDD, as well as intolerant to latch-up on all I /O pins. Upon power-up, an internal power-ON reset clears the serial registers, allowing all outputs to power up in the off-state when parallel control pins are also low. Although the serial register is cleared by this power-ON reset, software must still - 33882 20 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION FUNCTIONAL PIN DESCRIPTION initialize the outputs with an SPI command prior to changing the MODE pin from a high to a low state. This assures known output states when MODE is low. 33882 Analog Integrated Circuit Device Data Freescale Semiconductor 21 PACKAGING PACKAGE DIMENSIONS PACKAGING PACKAGE DIMENSIONS For the most current package revision, visit www.freescale.com and perform a keyword search using the "98A" listed below.
