製品詳細

The MAX17617EVKIT# evaluation kit (EV kit) features the MAX17617 electronic fuse (eFuse) set up for 5V to 28V operation with a 7A auto-retry current limit. A 3.3V buck regulator provides a voltage for pull-ups and logic to run indicator LEDs on the board. The board also includes an additional external N-channel field-effect transistor (FET) for reverse conduction protection.
