1.1 Introduction

The BQ25756EEVM can be evaluated for up to 180 W range of USB Extended Power Range (EPR) and up to 7 cell Li-Ion battery charging implementing CC/CV profile. Typical applications include Kick eScooters, cordless power tools, garden tools, robotic lawn mowers, portable power stations, cordless vacuum cleaners, vacuum robots, solar chargers, and USB-PD EPR applications.

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 BQ25756EEVM 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 BQ25756EEVM has 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 this board, all terminals must be considered high voltage and hazardous live. Electric shock is possible when connecting the board to live wire. The board 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.
