GENERAL DESCRIPTION

ACT2802 is a space-saving and high-performance

low-profile single-chip solution for backup battery

pack and standalone battery charger. ACT2802

integrates all the functions that a backup battery

pack needs, including switching charger, boost

converter and LED indication.

ACT2802 operates at 1.1MHz for switching charger

and 0.55MHz for boost converter allowing tiny

external inductor and capacitors. ACT2802 provides

a direct power path from input to output with

programmable current limit while providing power

to switching charger. Output has higher priority than

battery charger if the programmed input current limit

is reached.

ACT2802 charges battery with full cycle of

preconditioning, fast charge with constant current

and constant voltage until end of charge. The

battery charger is thermally regulated at 110°C with

charge current foldback.

ACT2802 boost converter steps battery voltage up

to 5V. Boost converter features high efficiency,

constant current regulation, short circuit protection

and over voltage protection.

ACT2802 provides 3.5mA constant currents to drive

4 LEDs to indicate battery level and charge status.
