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: 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.

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.
