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 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.
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
