M62241FP Datasheet | Mitsubishi Electric

MITSUBISHI(Standard Linear IC) SINGLE CHIP BATTERY CHARGER CONTROL IC DESCRIPTION The M62241FP is designed as 1chip Integrated Circuit for controlling battery charger. This IC contains analog circuits needed for controlling charge, and timesequential-control logic circuits. This IC has various functions such as not only charge-controlling but also battery temperature detection, protection against overcurrent / over-voltage, and safety timer. The bination with some parts gives a charge circuit for Lithium -ion battery easily.
