BQ25858-Q1, BQ25858B-Q1 are automotive grade, wide input voltage, bidirectional switched-mode buck-boost controllers. The devices offer high-efficiency regulation over a wide voltage range with output CC-CV control. The devices integrate all the loop compensation for the buck-boost converter, thereby providing a high density solution with ease of use. In reverse mode, the devices draw power from the output supply and regulate the input terminal voltage with an added constant current loop for protection.

Besides the I2C host-controlled mode, the device also supports programmable hardware limits. Input current, and output current regulation targets can be set with single resistor on the IIN, and IOUT pins, respectively. By default, the device is programmed to provide 5V output, and the target output voltage can be adjusted via the VOUT_REG register bits.
