The device charges the battery in five phases: trickle charge, pre-charge, constant current, constant voltage and an optional top-off charging phase. At the beginning of a charging cycle, the device checks the battery voltage and regulates current and voltage accordingly.
If the charger device is in DPM regulation or thermal regulation during charging, the charging current can be less than the programmed value. In this case, termination is temporarily disabled and the charging safety timer is counted at half the clock rate.
