3 Description

The BQ25820 is a wide input voltage, switchedmode

buck Li-Ion, Li-polymer, or LiFePO4 battery

charge controller with direct power path control.

The device offers high-efficiency battery charging

over a wide voltage range with accurate charge

current and charge voltage regulation, in addition to

automatic charge preconditioning, termination, and

charge status indication. The device integrates all the

loop compensation for the buck converter, thereby

providing a high density solution with ease of use.

In reverse mode, the device draws power from the

battery and regulates the SYS terminal voltage.
