With the steady increase in high voltage eMobility applications semiconductor-based resettable fuses are quickly replacing mechanical relays/contactors and traditional non-resettable fuses. The eFuse concept is an innovative new trend for protecting both the user and the hardware in high voltage/power applications.

In this new reference design, an eFuse featuring SiC MOSFETs and a VOA300 optocoupler was designed to handle continuous power up to 40 kW. It has been designed to operate continuously at full power with less than 30 W of losses and no active cooling, and also features a preload function, continuous current monitoring and overcurrent protection (with shutdown in less than 2.5 µs).
