Product Details

The MAX17851 evaluation kit (EV kit) is used to demonstrate the features and capabilities of the MAX17851 SPI to UART safety monitoring bridge. With communication established, control of the MAX17851 EV kit is executed through the EV kit graphical user interface (GUI) on the host PC. The GUI is Windows XP^®-, Windows Vista^®-, Windows^® 7-, and Windows 10-compatible and is available through your local Maxim Integrated sales office.

The MAX17851 EV kit design provides a convenient platform for evaluating the features and functions of the IC, in addition to the IC’s electrical parameters. The EV kit with vertical communication connectors enables the user to quickly build and evaluate the universal asynchronous receiver transmitter (UART) specially designed to interface with Maxim’s battery management data acquisition system.

Applications

Battery Management Systems (BMS)
Electric and Hybrid Electric Vehicles (EV/HEV)
Energy Storage Systems (ESS)
