ACT2813/ACT2813C

Rev 2, 19-May-15

5V/2.4A Power Bank Solution

FEATURES

APPLICATIONS

• Power Bank

• Mobile Power

• Backup Battery Pack

• Standalone Battery Charger with USB Output

• Dedicated Single Chip Solution for Mobile Power

With Minimal Component Count

• 2.4A Continuous Output Current in Boost Mode

• 2.4A Switching Charger Current

• 96% Boost Efficiency (Vbat=4.1V)

• Adaptive to 10mA-2400mA Input Sources

• Battery Disconnection at Output Short

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.

• <10µA Low Battery Leakage Current at HZ

Mode During Storage

• Boost Auto Turn-off at No Load and Push

Button Turn-on

• Battery Over Current, Over Voltage, Over

Temperature and Short Circuit Protections

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.

• Boost Auto Startup with Load Detection

• Prioritized Power Path from Input to Output

• 5V+/-100mV Output Voltage in Boost Mode

• 1.1MHz/0.55MHz Switching Frequencies

• 2.2uH Inductor and Low Profile Ceramic

Capacitor

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.

• 4 LEDs Battery Level and Status Indication

• Battery Impedance Compensation

• Full Cycle of Battery Charge Management

Preconditioning, Fast Charge, Top off and End

of Charge

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.

• Charge Current Foldback at 110°C Die

Temperature

• IC Over Temperature Protection at 160°C

• FCQFN 4x4-20 Package

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.
