Microchip Technology High-Voltage Auxiliary E-Fuse Reference Design

Microchip Technology High-Voltage Auxiliary E-Fuse Reference Design Boards are demonstrator boards used for high-voltage auxiliary E-Fuse technology in Hybrid Electric Vehicle (HEV) and Electric Vehicle (EV) applications. These boards implement a Time-Current Characteristic (TCC) curve that helps migrate to non-automotive applications such as DC solid-state circuit breakers. The high-voltage auxiliary E-fuse reference design boards feature up to 30A continuous output load current and two modes of short-current detection, including edge-triggered and ride-through edge-triggered. These reference design boards can provide the diagnostic status of current, temperature, and bias supply measurements. The high-voltage auxiliary E-fuse reference design boards also feature a LIN communication interface for configurability and diagnostics. Applications include DC smart grids, charging stations, EVs, and HEVs.
