Control of Lithium Ion Batteries Charging

Monolithic IC MM1332

Outline

This IC is a high precision constant voltage constant current power source controller for lithium ion batteries

serving as power drivers for P-MOS FET. It was developed for use with one to three cell chargers, and the

constant current value can be set freely with external resistance. It has a built-in amplifier for detecting low

battery voltage. Using this IC enables the easy addition of a lithium ion battery charging function to

conventional battery-charging devices.

Features

1. Output voltage (Ta=

-20°C+~70°C)

3Cell : 12.3V/12.6V 1ꢀ0mV

2Cell : 8.2V/8.4V 100mV

1Cell : 4.1V/4.2V ꢀ0mV

2ꢀ0µA typ.
