MM1433 [Lithium-Ion Battery Charge Control (1 to 2 cells) ] Mitsumi
Mitsumi

Outline
This IC is used to control charging of lithium-ion batteries. It is a one-chip charge control IC where the protection circuit incorporates constant-current/constant-voltage charge and precharge, overcharge timer, and battery temperature detection functions. It was developed by adding the above-described functions to the conventional MM1332 and MM1333.

Features
1. Charge voltage accuracy (Ta=0°C ~ +50°C) ±30mV/cell
2. Current consumption 5mA typ.
3. Precharge function
4. Recharge function
5. Overcharge timer
6. Battery temperature detection function
7. Adaptor (primary side) abnormality detection function
8. LED driver (R, G pins)
9. Available for 1 to 2 cells

Applications
   For lithium-ion battery charge control
