1.1 Introduction

The BQ25758EVM and BQ25758AEVM can be evaluated for the full 240W range of USB Extended Power Range (EPR) in forward and reverse power direction. Typical applications include USB-PD extended power range applications, docking stations, monitors, and Portable Power Supplies.

This EVM does not include the EV2400 or USB2ANY interface device and does not provide any electrical isolation for the digital interfaces. EV2400 or USB2ANY must be ordered separately to evaluate the BQ25758EVM or BQ25758AEVM and electrical safety considerations must be considered when interfacing between the PC and the EVM board. When interfacing the EVM to the PC through the digital interfaces, digital isolators with isolation boundary is recommended.

The BQ25758EVM and BQ25758AEVM have smaller clearance and creepage than normally used on high voltage boards as well as not having an isolation boundary. If you apply high voltage to these boards, all terminals must be considered high voltage and hazardous live. Electric shock is possible when connecting the board to live wire. The boards must be handled with care by a professional. For safety, use of isolated test equipment with various protection features (such as overvoltage and overcurrent) is recommended.
