MITSUMI Control of Lithium Ion Battery Charging and Discharging MM1214 Control of Lithium Ion Battery Charging and www.DataSheet4U.com Discharging Monolithic IC MM1214 Outline This IC controls constant current charging and excess discharge for lithium-ion batteries (sub-batteries). It performs constant current charging, stops charging at set voltages, and prevents excess discharging. When the voltage falls below a set level, it prohibits discharges and reduces IC current consumption nearly to zero. Features During charging 1. Input voltage range 2. Current consumption (VIN pin) 3. Current consumption (VCC pin) 4. Charging current switching voltage 5. Charging current (normal conditions) 6. Charging current (low voltages) 7. Charging control voltage (Ta =-20~+70°C) 8.
