描述 Description

3 or 4 Cell Li-Ion Battery Protection and Monitor ICThe X3100 is a protection and monitor IC for use in battery packs consisting of 4 series Lithium-Ion battery cells. The X3101 is designed to work in 3-cell applications. Both devices provide internal over-charge,over-discharge, and over current protection circuitry,internal EEPROM memory, an internal voltage regulator, and internal drive circuitry for external FET devices that control cell charge, discharge, and cell voltage balancing.
