MITSUMI Lithium-Ion Battery Charge Control (1 cell) MM1333 Lithium-Ion Battery Charge Control (1 cell) Monolithic IC MM1333 Outline 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 comparato
