GENERAL DESCRIPTION
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 a dual cell battery
with boost configuration in three phases: precondition-
ing, 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.
If input 5V is not present, ACT2803 discharge a dual cell
battery with buck configuration to provide 5.07V+/-1%
to output ports. There is a power path from input to
output. The cycle-by-cycle peak current mode control,
constant current regulation, short circuit protection and
over voltage protection maximize safe operation.
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.
ACT2803 is available in a thermally enhanced
5mmx5mm QFN55-40 package with exposed pad.
