  • Product Details

    The MAX6397 evaluation kit (EV kit) demonstrates a high-voltage overvoltage protection circuit for applications that must survive load dump and high-voltage transient conditions. This EV kit is a fully assembled and tested surface-mount board.

    The EV kit supports high-output currents up to 5A, runs at voltages up to 72V, and can withstand temperatures ranging from -40°C to +105°C. Two alternate voltage inputs implement two different schemes for reverse-battery protection. Connections to the on-chip linear regulator, capable of driving 100mA, and the power-good (POK) signal are also provided.
