This IC was developed for lithium-ion battery charge control. It controls charging with an external PNP power transistor or p-MOSFET. It is used only for 1-cell batteries and provides a high-precision charge voltage. Charge current can be set with an external resistor. In addition, it includes the functions of MM1332 (conventional IC) and incorporates a comparator for full-charge detection.
