MITSUMI Protection for Lithium-Ion Batteries (4-serial cells) MM3114 Series Protection for Lithium-Ion Batteries (4-serial cells) Monolithic IC MM3114 Series Phased Out Products Outline This IC integrates overcharge/overdischarge protection functions for lithium-ion/lithium polymer rechargeable batteries and the regulator functions into one chip by high voltage CMOS process. It can be used with other gas gauge IC, security IC, etc. as it includes a regulator. Overcharge/overdischarge can be detected to protect 4-cell lithium-ion/lithium polymer batteries. Charge/discharge control is perfomed using two external Pch MOS FETs. Features 1. Overcharge detection voltage Selectable between 4.0~4.5V by 5mV steps Accuracy ±25mV 2. Over-discharge detection voltage Selectable between 2.0~3.
