■Applications
■General Description
■Features
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.

Note : 1. VOUT(T) = Specified Output Voltage : VOUT(E) = Effective Output Voltage.
2. Parameter characteristics marked with an asterisk may vary according to which type of external transistor is used.
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
Ω : CL, 10 µF 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. VDIF = { VIN1 - VOUT1 }
VOUT1 = A voltage equal to 98% of the Output Voltage whenever an amply stabilised IOUT {VOUT(T)+1.0V} is input.
VIN1 = The Input Voltage when VOUT1 appears as Input Voltage is gradually decreased.
6. The Maximum Output Current value represents the value at the time the Output Voltage has decreased to VOUT (E) x 0.9.
Due to the limitations of Continuous Total Power Dissipation with the 2SA1213 transistor, the Maximum Output Current
Value cannot be continually achieved.

■Directions for use
●Notes 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 10µF (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 10µF (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 10µF (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 200kΩ 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 1µF (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.

Input Pin
VSS
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. (Use within the stipulated absolute maximum ratings).
