| NCMOS Low Power Consumption N4 Voltage Regulators and 2 Voltage Detectors Built-In. NOutput Control Circuit NOutput Voltage and Detect Voltage Range : 2V ~ 5V NOutput Voltage Accuracy and Detect Voltage Range: 2% N16 Pin TSSOP Package The XC641A series are highly precise, low power consumption, multi power supply IC s, manufactured using CMOS and laser trimming technologies. The IC consists of a highly precise reference, 4 voltage regulators, 2 voltage detectors, and an output control circuit. Because the regulators can be disabled through the EN pins, in standby, current consumption can be greatly reduced. The minimal input / output differential supports efficient voltage circuit design. The XC641A is particularly suitable for use with battery powered equipment where power supply control is all important. The series comes in a small TSSOP-16 package.

A transistor with a value of hFE = 100 or greater and a low saturation voltage is recommended. Unless otherwise stated, use of the following external components are recommended : PNP Transistor, 2SA1213-Y : RBE, 200K : CL, 10 F Tantalum Capacitor. 3. The values given for ISS refer to the actual IC values ( see application circuits ) 4. The IC's supply current is calculated as follows : Supply Current = ISS + ( Load Current / hFE ) + ( 0.6 / RBE ) 5.

The Maximum Output Current value represents the value at the time the Output Voltage has decreased to VOUT (E) x 0.9.

( This does not include current flowing through externally connected components nor the input current through the detect pins of voltage detectors 1, 2 ) 656 GNotes on Use : IC 1. Please sufficiently strengthen the GND wiring and the power supply (VDD) line, as when the power supply line impedance is high, the voltage regulators and detectors are prone to oscillation leading to possible instability. 2. In order to lower the power supply line impedance, we recommend that a capacitor of 10F (Tantalum) or more be connected at the shortest point possible between the VDD pin and the GND pin. 3. To protect the IC from surge at the input pin, an input protect diode is built-in. Therefore, do not apply voltages that exceed the VDD pin voltage. 4. Please ensure that the sum total of the IC's power consumption does not exceed the stipulated figure for total continuous power dissipation ( Pd ). Pd < P1 + P2 + P3 + P4 + P5 + P6 The following equations can be used to calculate the IC's power consumption : Regulator 1 : P1 = ( VDD - 0.6V ) x IEXT1, IEXT1 to IOUT1 / hFE Regulator 2 : P2 = ( VDD - 0.6V ) x IEXT2, IEXT2 to IOUT2 / hFE Regulator 3 : P3 = ( VDD - VOUT3 ) x IOUT3 Regulator 4 : P4 = ( VDD - VOUT4 ) x IOUT4 Detector 1 : P5 = VDOUT1 x IDOUT1 Detector 2 : P6 = VDOUT2 x IDOUT2 Voltage Regulator 1, 2 ( External transistor type ) 1. In order to prevent regulator oscillation ( caused by power supply impedance ), we recommend that a capacitor of 10F (Tantalum) or more be connected between the external transistor's emitter and the GND pin. 2. In order to prevent regulator phase compensation, we recommend that a capacitor of 10F (Tantalum) or more be connected between the IOUT1, IOUT2 pins and the GND pin. 3. In order to prevent oscillation we recommend that a resistor of around 200k be connected between the external transistor's base pin and emitter pin. Voltage Regulator 3, 4 ( Built-in transistor type ) 1. Please connect a capacitor of 1F (Tantalum) or more between the voltage regulator's output pins ( OUT3, OUT4 ) and the GND pin. 2. In order to prevent regulator oscillation ( caused by power supply impedance ), we recommend that a capacitor be connected between the VDD pin and the GND pin. 3. Since a short circuit protector is not built-in, when the OUT3 or OUT4 pin is short circuited to the GND pin, resulting surge current may damage the IC. Voltage Detectors 1. In order to prevent regulator oscillation ( caused by power supply impedance ), we recommend that a capacitor be connected between the VDD pin and the GND pin. 2. Should the VDD pin voltage become excessively low, we recommend that a Schottky Diode be connected between the CD1 pin and the VDD pin, in order to prevent voltages over the established VDD + 0.3V being applied to the capacitor connection pin ( CD1 ). Please use a Schottky Diode of VF = 0.3V ( IF = 10mA ). If a large reverse current, IR (max.), is used, the delay circuit current will increase and delay time will be shortened. 3. When not using the delay circuit, please use the IC with the CD1 pin open. 10 657 Input Pin The XC641A has a built-in circuit to protect the IC against surge at the input pin. Should a voltage higher than VDD be applied at the input pin, please note that current will flow from the input pin to VDD.
