3 Description
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.
