Isolated FET driver family aims at relay replacement apps in industrial and automotive uses

September 22, 2016 By Aimee Kalnoskas

Developers have traditionally used EMRs and optocoupler-based SSRs in switching applications, and both technologies have limitations. EMRs are costly, slow, bulky and noisy. These drawbacks are driving double-digit growth in SSR usage, but even SSRs pose challenges. Optocoupler-based SSRs have inherent limitations such as shorter lifetimes due to LED aging, reduced performance and stability at […]
