EVs with 400 V battery systems were introduced over a decade ago and now we are seeing the industry migrate toward 800 V systems primarily to support DC fast charging. With the increased voltage and lessons learned from 400 V systems, designers are now focused on enhancing the performance of high-voltage protection circuits along with improving reliability.

The incumbent solution using a fuse, contactor or relay is being reevaluated for faster-reacting, more robust and reliable solutions such as pyrofuse and electronic fuse, or E-Fuse. An emerging solution is an E-Fuse based on Microchip's mSiC™ Technology.

Watch this webinar to learn how SiC offers a high operating voltage, high operating temperature, low on-state resistance, low off-state leakage current and durability against over-voltage transients. The E-Fuse's solid-state design eliminates reliability issues related to arcing, mechanical wear-out, contact bounce and tack welds.
