Input

Description

Charging ON/OFF control input pin.

SW1=VCC : OFF, SW1=GND : ON

Goes OFF when open as it is pulled up to VCC.

Low voltage detection circuit ON/OFF control input pin.

SW2=VCC : OFF, SW2=GND : ON

Goes OFF when open as it is pulled up to VCC.

Low voltage detection circuit output pin.

3

LV Output

NPN-Tr open collector output; goes ON (low level) for low voltage.

4

GND

Ground pin.

Current detection pin. Detects current when external resistor voltage drops and

5

CS Input

controls current. Reference voltage 0.1V=external resistance current value

6

CEL

Input

* Battery voltage input pin

Six types depending on rank : 4.1V, 8.2V, 12.3V, 4.2V, 8.4V, 12.6V, (TYP.)

Constant voltage circuit output pin. Controls external P-MOS FET gate and

7

EXT Output

charges constant voltage.

8

VCC

Power supply input pin.

*G : Constant voltage circuit input pin

External resistance ratio (R1 : R2) enables setting constant voltage circuit output voltage.

Low voltage detection voltage is set for one cell (4.1V or 4.2V).
