DESCRIPTION

The M62241FP is designed as 1chip Integrated Circuit for controlling battery charger. This IC contains analog circuits needed for controlling charge, and time-sequential-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 combination with some parts gives a charge circuit for Lithium-ion battery easily.

FEATURE

● Designed to operate at as low as 4V

● CR oscillation circuit for internal logic

● Terminating timer for preventing overcharge 30min. indicating timer

● Main output switch drive circuit

● LED drive circuit (1 system)to indicate charging status

● System reset circuit for detecting the lowering of supply voltage

● Temperature detection for Lithium-ion battery

● Voltage/current control for feedback to the primary side of switching regulator

● Various protections such as overvoltage detection at charging, overcurrent detection at adaptor connection

Application

VCR with camera, cellular phone, battery charger for general electronic equipments.
