GENERAL DESCRIPTION

The ACT2823 is a space-saving, dedicated single-chip

solution for dual-cell battery charge and discharge

control. It is optimized for power bank and battery

backup systems. The ACT2823 operates in three

modes: charge mode, discharge mode and HZ mode.

It charges dual Li-Ion batteries from a USB input while

also delivering power to the load. Automatic power path

control always gives priority to the load.

When the USB input is not present, the ACT2823

powers the load at 5.07V from the batteries. The cycle-

by-cycle peak current mode control, constant current

regulation, short circuit protection and over voltage

protection maximize safe operation.

ACT2823’s HZ mode minimizes the batteries current

drain to less than 10µA to help maintain fully charged

batteries for products with long storage, shipping, and

shelf life.

ACT2823 provides 4 LED drive pins for battery capacity

level and charge status indication to indicate 25%, 50%,

75% and 100% battery charge levels. Multiple LED

indications patterns are programmable.

ACT2823 is available in a thermally enhanced

5mmx5mm QFN55-40 package with exposed pad.
