STEVAL-EFUSE01

Evaluation board based on the STEF01 fully programmable universal electronic fuse. It allows full evaluation of the STEF01 E-fuse and is designed to help users to test and develop a power path protection to the system. The STEF01 E-fuse integrates a control circuit and low on-resistance MOSFET switch and provides a full set of protections including overcurrent, overvoltage and inrush current. Users can adjust UVLO threshold, clamping voltage and overload current limits through mechanical trimmers. An external MOSFET, driven by the STEF01 gate driver pin can be mounted to implement a reverse current blocking circuit. The inrush current can be controlled by the output voltage ramp rate with the dedicated soft start circuit embedded in the STEF01 device. Typical applications include hot-swap boards, electronic circuit breakers, distributed power systems, industrial automation, white goods/appliances and telecom power modules.
