1.1 Introduction

The BQ25750EVM evaluates for applications that use greater than a 100 W USB input with the new USB-C Power Delivery (PD) Extended Power Range (EPR) and up to 13 cell Li-Ion battery charging implementing CC/CV profile. Typical applications include medical equipment, solar backup chargers, energy storage systems, drones, cordless power and garden tools.

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 can be ordered separately to evaluate the BQ25750EVM and considering electrical safety is important when interfacing between the PC and EVM board. When interfacing the EVM to the PC through the digital interfaces, digital isolators with isolation boundary is recommended.

The BQ25750EVM does not have an isolation boundary and has smaller clearance and creep than normally used on high-voltage boards. If the user applies high voltage to this board, all terminals are considered high voltage and hazardous when live. Electric shock is possible when connecting the board to live wire. The board must be handled by a professional with care. TI recommends the use of isolated test equipment with safety protection features (such as overvoltage and overcurrent).
