Full charge detection pin

The current is detected through the voltage drop across an external

resistance, to control the full-charge signal.

The ratio of the charge current set by CS1 and the current at full-charge signal

output is (VIC)/(0.1 V R4/(R3+R4))

Current detection pin

The current is detected through the voltage drop across an external

resistance, to maintain a constant current. The current value can be set using

0.1 V/(R3+R4).

Battery voltage input pin

The battery voltage is detected and used to maintain the voltage at the

prescribed value.

A low-voltage detection circuit is also present, and charging is forbidden when

the battery voltage is less than 2V.

Constant-voltage circuit output pin

The base of an external PNP transistor or gate of a P-MOS FET is controlled in

constant-voltage charging.
