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.
