5.1 Charging a Battery

The IS2062/64 SoC has a built-in battery charger, which is optimized with lithium-ion and lithium-polymer batteries. The battery charger includes a current sensor for charging control, user programmable current regulator, and high accuracy voltage regulator.

The charging current parameters are configured by using the UI tool. An adapter is plugged in to activate the charging circuit. Reviving, pre-charging, constant current and constant voltage modes and re-charging functions are included. The maximum charging current is 350 mA. The following figure illustrates the charging curve of a battery.
