3 Description
The BQ25750 is a wide input voltage, switched-mode
buck-boost 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-boost 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.
