The BQ25856-Q1 is an automotive grade, wide input voltage, switched-mode buck-boost Li-Ion, Li-polymer, or LiFePO4 battery charge controller with bidirectional power flow support. 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 input terminal voltage with an added constant current loop for protection.

Besides the I2C host-controlled charging mode, the device also supports standalone charging mode via resistor programmable limits. Input current, charge current, and charge voltage regulation targets can be set via the ILIM_HIZ, ICHG, and FB pins, respectively.
