Constant Current Charging
The PM6658 IC supports constant current charging of the main battery by controlling the charger pass
transistor and the battery transistor. The constant current charging continuesuntil the battery reaches
its target voltage, 4.2V.
Constant Voltage Charging
Constant voltage charging begins when the battery voltage reaches a target voltage, 4.2V.
The end of constant voltage charging is commonly detected 10% of the full charging current.
