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
