The A308 is a monolithic switching charger for
2-series Li-ion cells battery, It achieves up to 2A
charge current with voltage mode PWM step- down
(buck) switching architecture.A308 regulates the
battery voltage and charge current with CV(constant
voltage) and CC(constant current) loops. Fault
condition includes thermal shutdown、time out and
output short. Other safety features include battery
temperature monitoring and charge status indication.
The A308 is available in 14-pin SOP package.
