IC for Control of Lithium-ion Betteries Charging
Monolithic IC MM1438
Outline
This IC is used to control charging of lithium-ion batteries consisting of a single cell. It is a modification of the
previous MM1332 charging-control IC, with improved charging voltage accuracy and a smaller package.
Features
1. Charging voltage accuracy (Ta=25°C)
2. Charging voltage accuracy (Ta=0 to 50°C)
3. Consumption current (charging on)
4. Consumption current (charging off)
5. Low-voltage detection
6. Leakage current between CEL and CS
±25mV/cell
±30mV/cell
