Description

The BQ25858 and BQ25858B evaluation modules (EVM) are a complete evaluation system for the BQ25858-Q1 and the BQ25858B-Q1 ICs. The EVMs have a max input and output of 55V and a max output current of 10A.

The BQ25858-Q1 and BQ25858B-Q1 ICs are wide voltage, bidirectional switched-mode buck-boost controllers. These devices offer high-efficiency power conversion over a wide voltage range with output CC-CV control. These devices have a wide input range of 4.2V to 60V and a wide output range of up to 60V.

The BQ25858EVM and the BQ25858BEVM use the same hardware. The only difference between the two boards is the I2C address. The BQ25858-Q1 has the I2C address of 0x6B and the BQ25858B-Q1 has the I2C address of 0x4B.
