Traditional mechanical fuses and circuit breakers just can’t keep up with modern high-voltage systems. In this video, we dive into Microchip’s trio of High-Voltage Auxiliary E-Fuse Reference Designs, engineered for ultra-fast, reliable protection in 400V and 800V DC systems. Powered by Microchip's advanced mSiC™ MOSFET technology, these reference designs address critical protection needs across automotive, industrial, and energy applications. 🔍 What We Cover: Three Innovative Approaches: Learn about our configurable auxiliary E-Fuse, a hardware-based E-Fuse (no firmware required!), and a bidirectional design supporting reverse current flow. Silicon Carbide (SiC) Advantage: Discover how mSiC technology enables higher efficiency, faster over-current detection, and smarter inrush current control. Solid-State Reliability: Say goodbye to wear-related failures. See how tuning your protection behavior improves long-term reliability and system diagnostics. Accelerated Development: Every design is a validated platform complete with schematics, BOMs, layouts, and user guides to shrink your time-to-market. If you're ready to build faster, smarter protection with a proven SiC-based architecture, these reference designs are your perfect starting point. 👉 Get started today: Download the design files, user guides, and documentation at https://www.microchip.com/e-fuse
