1.3 Device Information

The BQ25750EVM evaluation module (EVM) is an evaluation system for the BQ25750 IC. The BQ25750 IC is a buck-boost battery charge controller with direct power path control. The BQ25750 has a wide input range of 4.2 V – 70 V, a wide output voltage range of up to 70 V, and bi-directional capabilities.

The device offers high-efficiency battery charging with accurate charge current and charge voltage regulation over a wide voltage range. The design also includes automatic charge preconditioning, termination, and charge status indication. The device integrates loop compensation for the buck-boost converter, which provides a high-density design with ease of use. In reverse mode, the device draws power from the battery and regulates the SYS terminal voltage.

The device supports stand-alone charging mode through resistor programmable limits in addition to the I2C host-controlled charging mode. Input current, charge current, and charge voltage regulation targets are set through the ILIM_HIZ, ICHG and FB pins, respectively.
