1.1 Introduction

The BQ25751EVM can be used to evaluate 6V up-to 48V lead-acid charging, implementing the three-stage charging profile Bulk, Absorb, Float. Typical applications include: Fire alarm control panel, Anesthesia delivery system, Battery backup unit (BBU), Elevator main control panel, Emergency power supply, HVAC gateway, and Intrusion control panel

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 BQ25751EVM 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 BQ25751EVM 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.
