ACT2803 is a space-saving and dedicated single chip solution for dual-cell battery charge and discharge. It takes 5V USB input source to charge adual cell battery with boost configuration in three phases: preconditioning, constant current, and constant voltage. Charge is terminated when the current reaches 10% of the fast charge rate. The battery charger is thermally regulated at 110°C with charge current foldback.
ACT2803 provides 4 LED drive pins for battery capacity level and charge status indication to indicate 25%, 50%, 75%, and 75% above battery level with battery impedance compensation. The LED indication patterns are programmable .
