5V/2.5A Backup Battery Pack Manager

APPLICATIONS

FEATURES

 Dedicated Single Chip Solution for Mobile Power

 Backup Battery Pack

 Power Bank

 Mobile Power

With Minimal Component Count

 5V/2.5A Constant Output Current Limit in Boost

Mode

 Standalone Battery Charger with USB Output

 2.5A Switching Charger Current Limit

 Programmable 4.1V to 4.35V Battery Voltage

 95% Boost Efficiency (Vbat=4.1V)

 Adaptive to 10mA-2400mA Input Sources

 Battery Disconnection at Output Short

GENERAL DESCRIPTION

ACT2802/ACT2802B/ACT2802C is a space-saving

and high-performance low-profile single-chip

solution for backup battery pack and standalone

battery charger. ACT2802/ACT2802B/ACT2802C

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

ACT2802/ACT2802B/ACT2802C operates at

1.1MHz for switching charger and 0.55MHz for

boost converter allowing tiny external inductor and

capacitors. ACT2802/ACT2802B/ACT2802C

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.

 Battery Over Current, Over Voltage, Over

Temperature and Short Circuit Protections

 Boost Auto Startup with Load Detection

 Up to 3.0A Input Current Limit with Prioritized

Power Path to Output

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

 1.1MHz/0.55MHz Switching Frequencies

 2.2uH Inductor and Low Profile Ceramic

ACT2802/ACT2802B/ACT2802C 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.

Capacitor

 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

ACT2802/ACT2802B/ACT2802C 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

ACT2802/ACT2802B/ACT2802C provides 3.5mA

constant currents to drive 4 LEDs to indicate

battery level and charge status. Battery impedance

is compensated for battery level indication.

 IC Over Temperature Protection at 160°C

 QFN4x4-24 Package
