Outline
This IC is a lithium ion battery charging control IC. It is a 1-chip charging IC that combines constant current, constant voltage charging and protection circuits such as pre-charge and pre-charge timer battery temperature detection, all in one. The quick charge timer and full charge detection function have been eliminated, as compared to MM1433, and charging ON/OFF is controlled externally.

FEATUREs
1. Output voltage (Ta = 0°C ~ +50°C) 4.120 ± 30mV
2. Consumption current 3.5mA typ.
3. Pre-charge function
4. Adaptor (primary side) abnormality detection function
5. Timer error time ±10% (not including external deviation)
6. Battery temperature detection function
7. Pre-charge timer

APPLICATIONs Applications
1. Lithium ion battery charging control (with timer)
