GENERAL DESCRIPTION
ACT2813/ACT2813C is a space-saving and high-
performance low-profile single-chip solution for
backup battery pack and standalone battery
charger. ACT2813/ACT2813C integrates all the
functions that a backup battery pack needs,
including switching charger, boost converter and
LED indication.
ACT2813/ACT2813C operates at 1.1MHz for
switching charger and 0.55MHz for boost converter
allowing tiny external inductor and capacitors.
ACT2813/ACT2813C provides a direct power path
from input to output while providing power to
switching charger. Output has higher priority than
battery charger if the input current limit is reached.
ACT2813/ACT2813C 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.
ACT2813/ACT2813C boost converter steps battery
voltage up to 5V. Boost converter features high
efficiency, constant current regulation, short circuit
protection and over voltage protection.
ACT2813/ACT2813C provides 3.5mA constant
currents to drive 4 LEDs to indicate battery level
and charge status. Battery impedance is
compensated for battery level indication.
