IC for Control of Lithium-ion Batteries Charging
Monolithic IC MM1433
Outline
This IC is used to control charging of lithium-ion batteries. This one IC incorporates functions for constant-
current and constant-voltage charging and for precharging, for an overcharge timer, battery temperature
detection, and other protective functions. It was developed by adding to the previous MM1332 and 1333 the
above-described functions.
Features
1. Charging voltage accuracy
2. Consumption current
3. Precharge function.
4. Recharge function.
5. Overcharge timer.
6. Battery temperature detection function.
7. We can supply type for one and two cells.
鹵30mV/cell.
5mA typ.
Package
