3 Description

The BQ21080 is a linear battery charger IC focusing

on small solution size and low quiescent current for

extending battery life. The device is available in an

8-ball chipscale package which does not need HDI

PCB process for fabrication thereby reducing the PCB

cost. The device can support up to 800-mA charging

and system loads of up to 2.5 A.
