MITSUMI Control of Lithium Ion Batteries Charging MM1332 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±150mV 2Cell : 8.2V/8.4V±100mV 1Cell : 4.1V/4.2V±50mV 250µA typ. set by external resistance 0.
