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

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
