Description
The M62241FP is designed as 1 chip 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 over-current/over-voltage, and safety timer. The combination with some parts gives a charge circuit for Lithium-ion battery easily.
FEATUREs
• Designed to operate at as low as 4 V
• CR oscillation circuit for internal logic
• Terminating timer for preventing overcharge 30 m 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 over-voltage detection at charging, over-current detection at adapter connection
APPLICATION
VCR with camera, cellular phone, battery charger for general electronic equipments.
