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 comparator for full-charge detection.
Temperature conditions A: Ta=-25~75°C, B: Ta=-20~70°C, C: Ta=0~50°C,
D: Ta=0~40°C
