Protection of Lithium-Ion Batteries (for Double-Protect)
Monolithic IC MM1451
Outline
This IC is used for double-protection of lithium-ion batteries with from one to three cells, and has an ultra-
compact package. Short-circuits between cells accommodate series connections of one to three cells.
Features
1. Overcharge detection voltage accuracy (0°C to 50°C)
2. Consumption current (Vcell=3.8V)
3. Consumption current (Vcell=2.3V)
4. Pin I/O current between cells (Vcell=3.8V)
5. Delay time on overcharge voltage detection (Ct=0.22μF)
6. Output current (Vcell=V
