Description of Block Diagram
All 16 channels can be controlled via the serial interface (SPI). In addition to the serial control it is possible to control channel 1 to 4 and 9 to 12 direct in parallel with a separate input pin. The parallel input signal is either OR - operated or AND - operated with the respective SPI data bit. This boolean operation can be programmed via SPI control byte (see Chapter 5). The SPI interface also performs a diagnostic information for each channel.

Electrical and Functional Description of Blocks
The TLE6240GP is an 16-fold low-side power switch which provides a serial peripheral interface (SPI) to control the 16 power DMOS switches, and diagnostic feedback. The power transistors are protected against short to VBB, overload, overtemperature and against overvoltage by active zener clamp. The diagnostic logic recognizes a fault condition which can be read out via the serial diagnostic output (SO).

Power Supply & Reset
RESET - Reset pin. If the reset pin is in a logic low state, it clears the SPI shift register and switches all outputs OFF. An internal pull-up structure is provided on chip. In case the RESET Pin is pulled down statically, the device remains in Stand-by Mode Electrical Characteristics: Power Supply

Power Outputs
Power Transistor Protection Functions1) Each of the 16 output stages has its own zener clamp, which causes a voltage limitation at the power transistor when solenoid loads are switched off. The outputs are provided with a current limitation set to a minimum of 1 A for channels 1 to 8 and 3 A for channels 9 to 16. In the event of an overload or short to supply, the current is internally limited and the corresponding diagnosis bit combination is set. If this operation leads to an overtemperature condition, a second protection level will change the output into a low duty cycle PWM (selective thermal shut-down with restart) to prevent critical chip temperatures.

Diagnostic Functions and FAULT-Pin
The device provides diagnosis information about the device and about the load. There are following diagnosis flags implemented for each channel: * * * The diagnosis information of the protective functions, such as "over current" and "over temperature" The open load diagnosis The short to ground information.
For further details, refer to the Chapter "Control of the device" FAULT - Fault pin. There is a general fault pin (open drain) which shows a high to low transition as soon as an error occurs for any one of the sixteen channels. This fault indication can be used to generate a C interrupt. Therefore a `diagnosis' interrupt routine need only be called after this fault indication. This saves processor time compared to a cyclic reading of the SO information. As soon as a fault occurs, the fault information is latched into the diagnosis register. A new error will overwrite the old error report. Serial data out pin (SO) is in a high impedance state when CS is high. If CS receives a LOW signal, all diagnosis bits can be shifted out serially.

SPI Signal Description CS - Chip Select. The system microcontroller selects the TLE6240GP by means of the CS pin. Whenever the pin is in a logic low state, data can be transferred from the C and vice versa. * CS High to Low Transition: - diagnostic status information is transferred from the power outputs into the shift register - serial input data can be clocked in from then on - SO changes from high impedance state to logic high or low state corresponding to the SO bits CS Low to High Transition: - transfer of SI bits from shift register into output buffers
*
To avoid any false clocking the serial clock input pin SCLK should be logic low state during high to low transition of CS. When CS is in a logic high state, any signals at the SCLK and SI pins are ignored and SO is forced into a high impedance state. SCLK - Serial Clock. The system clock pin clocks the internal shift register of the TLE6240GP. The serial input (SI) accepts data into the input shift register on the falling edge of SCLK while the serial output (SO) shifts

It is essential that the SCLK pin is in a logic low state whenever chip select CS makes any transition. SI - Serial Input. Serial data bits are shifted in at this pin, the most significant bit first. SI information is read in on the falling edge of SCLK. Input data is latched in the shift register and then transferred to the control buffer of the output stages. The input data consist of 16 bit, made up of one control byte and one data byte. The control byte is used to program the device, to operate it in a certain mode as well as providing diagnostic information (see Chapter 6.2). The eight data bits contain the input information for the eight channels, and are high active. SO - Serial Output. Diagnostic data bits are shifted out serially at this pin, the most significant bit first. SO is in a high impedance state until the CS pin goes to a logic low state. New diagnostic data will appear at the SO pin following the rising edge of SCLK.

Control of the Device
Output Stage Control
The 16 outputs of the TLE6240GP can be controlled via serial interface. Additionally eight of these 16 channels can alternatively be controlled in parallel (Channel 1 to 4 and 9 to 12) for PWM applications.
6.1.1
Parallel Control and PRG - Pin
A Boolean operation (either AND or OR) is performed on each of the parallel inputs and respective SPI data bits, in order to determine the states of the respective outputs. The type of Boolean operation performed is programmed via the serial interface. The parallel inputs are high or low active depending on the PRG pin. If the parallel input pins are not connected (independent of high or low activity) it is guaranteed that the outputs 1 to 4 and 9 to 12 are switched off. The PRG pin itself is internally pulled up when it is not connected. PRG - Program pin. * * PRG = High (VS): Parallel inputs Channel 1 to 4 and 9 to 12 are high active PRG = Low (GND): Parallel inputs Channel 1 to 4 and 9 to 12 are low active
6.1.2 6.1.3
Serial Control of the Outputs: SPI Protocol Overview
Each output is independently controlled by an output latch and a common reset line, which disables all outputs. The Serial Input (SI) is read on the falling edge of the serial clock. A logic high input `data bit' turns the respective output channel ON, a logic low `data bit' turns it OFF. CS must be low whilst shifting all the serial data into the device. A low-to-high transition of CS transfers the serial data input bits to the output control buffer. The 16 channels of the TLE6240GP are divided up into two parts for the control of the outputs (ON, OFF) and the diagnosis information. Serial Input (SI) information consists of 16 bit. 8 bit contain the input driver information for channel 1 to 8 or for channel 9 to 16. The remaining 8 bits are used to program a certain operation mode. Serial Output (SO) data consists of 16 bit containing the diagnosis information for channels 1 to 8 or channels 9 to 16 with two bits per channel. Channel 1 to 8: * * * Control Byte 1: Operation mode and diagnosis select for channels 1 to 8 Data Byte1: ON/OFF information for channel 1 to 8 DIAG_1: Diagnosis data for channels 1 to 8

Reading back of the eight inputs and `1-bit Diagnosis' provided
Control Byte
If the TLE6240GP is used as bare die in a hybrid application, it is necessary to know if proper connections exist between the C-port and parallel inputs. By entering `HHLL' as the control word, the first eight bits of the SO give the state of the parallel inputs, depending on the C signals. By comparing the IN-bits with the corresponding C-port signal, the necessary connection between the C and the TLE6240GP can be verified - i.e. `read back of the inputs'. The second 8-bits fed out at the serial output contains `1-bit' fault information of the outputs (H = no fault, L = fault). In the expression given below for the output byte, `FX' is the fault bit for channel X. Table 6

Echo-function of SPI
Control Byte
To check the proper function of the serial interface the TLE6240GP provides a "SPI Echo Function". By entering HLHL as control word, SI and SO are connected during the next CS period. By comparing the bits clocked in with the serial output bits, the proper function of the SPI interface can be verified. This internal loop is only closed once (for one CS period). The "Echo Function" does not cause any internal processing of data and after the next CS signal the SO data is `0' (all registers reset).

Two Bits per Channel Diagnostic Feedback
Normal function: The bit combination HH indicates that there is no fault condition, i.e. normal function. Overload, Short Circuit to Battery (SCB) or Overtemperature: HL is set when the current limitation gets active, i.e. there is a overload, short to supply or overtemperature condition. Open load: An open load condition is detected when the drain voltage decreases below 3 V (typ.). LH bit combination is set. Short Circuit to GND: If a drain to ground short circuit exists and the drain to ground current exceeds 100 A, short to ground is detected and the LL bit combination is set.
A definite distinction between open load and short to ground is specified by design. The standard way of obtaining diagnostic information is as follows: Clock in serial information into SI pin and wait approximately 150 s to allow the outputs to settle. Clock in the identical serial information once again - during this process the data coming out at SO contains the bit combinations representing the diagnosis conditions as described in Figure 21. Reset of the Diagnosis Register The diagnosis register is reset after reading the diagnosis data (after the falling CS edge). This is done for channels 1-8 and channels 9-16 separately depending on the previous command. Data Sheet 28 Rev.3.3, 2010-02-15
