Texas Instruments BQ25858-Q1EVM Evaluation Module
Texas Instruments BQ25858-Q1EVM Evaluation Module is a complete evaluation system for the BQ25858-Q1 ICs. The BQ25858-Q1 ICs are wide-voltage, bidirectional switched-mode buck-boost controllers. The ICs provide high-efficiency power conversion over a wide voltage range with output CCCV control. The BQ25858-Q1 has a wide 4.2V to 60V input range and a wide output range of up to 60V.
The BQ25858-Q1EVM features a 10A max output current, 55V input and output voltage, and implements a 0x6B I2C address.
The evaluation module does not include the EV2400 or USB2ANY interface devices or provide electrical isolation for the digital interfaces. The EV2400 or USB2ANY must be ordered separately to evaluate the evaluation module, and electrical safety considerations must be regarded when interfacing between the PC and the EVM board.
