Outline
This IC was developed for use in charging lithium ion batteries. PNP power transistor or P-MOS FET is mounted externally to control charging. This IC is for use with a single cell only, and provides precise control of the charging voltage ; the charging current can be set through an external resistance. In addition to the functions of the MM1332, it incorporates a comparator for full-charge detection.

FEATUREs
1. Output voltage 1 (Ta=25°C) 4.100V±35mV
2. Output voltage 2 (Ta=0°C~+40°C) 4.100V±50mV
3. Constant-current output Current limit 100mV±10mV
                                           Constant current value = current limit/external resistance
4. Low-voltage (LV) detection function 2.00V±100mV
5. Full-charge detection function Detection voltage 31mV±5mV
