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.
