High-Voltage Auxilliary E-Fuse Reference Design

With increasing high-voltage content in automotive and industrial end equipment comes a greater need for protection. Electronic Fuse (E-Fuse), enabled by Microchip’s Silicon Carbide technology, provides a faster, more reliable method for protecting power electronic applications. E-Fuse solutions can detect and interrupt fault currents microseconds faster than traditional approaches. Fast response times limit peak fault current and prevent a fault event from becoming a hard failure.
The high-voltage auxiliary E-fuse demonstrator leverages the benefits of our 700V and 1200V Silicon Carbide (SiC) technology and other technologies to provide a complete solution. Additionally, this design implements a Time-Current Characteristic (TCC) curve that helps you migrate to non-automotive applications such as DC solid-state circuit breakers.
