Control of Lithium Ion Battery Charging and 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.
