XC6801 Series
1 Cell Li-ion Battery Linear Charger IC
with Constant-Current/Constant-Voltage
ETR2502-003a
GENERAL DESCRIPTION
The XC6801 series is a const ant-current/constant-voltage linear char ger IC for singl e cell lithium-ion bat teries. The XC6801
includes a reference voltage source, battery voltage monitor, driver transistor, constant-current/constant-voltage charge circuit,
overheat protection circuit and phase compensation circuit. The battery charge termination voltage is internally set to 4.2V
0.7% and the trickle ch arge voltage and accuracy is 2. 9V 3%. In trickle ch arge mode, a safe b attery charge is p ossible
because a pproximately o nly 1/10 of the fu ll charge curre nt is suppl ied to the b attery. As it is possible to s elect a hig hly
accurate charge current of either 100mA (MAX.) for L level input to the LIM pin or 500mA (MAX.) for H level, the series is ideal
for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s
charging state via connection to an external LED.
APPLICATIONS
USB charge applications
Charging docks, charging cradles
MP3 players, portable audio players
Cellular phones, PDAs
Bluetooth headsets
