DESCRIPTION

1

ON/OFF

ON/OFF control input pin for the IC.

ON/OFF = GND: ON

2

LVEN

Low voltage detection circuit ON/OFF control.

LVEN = GND: ON

3

LV

Low cell voltage detection circuit output pin.

Open collector; Active-LOW.

4

Connect to negative pole of battery.

5

CS

Current detection pin.

Detects current by drop in external resistor

voltage and controls rated current.

Current value can be set at 0.1 V/R1 typ.

6

Battery voltage input pin.

Detects battery voltage and controls rated

voltage to the prescribed voltage value.

7

DRV

Charging control output pin drives external

PNP-Transistor to control charging.

8

Power supply input pin.
