Maxwell’s equations: An intuitive view for engineers

January 17, 2019 By Aimee Kalnoskas 1 Comment

by Asem Elshimi, Design Engineer, Silicon Labs “From a long view of the history of mankind, seen from, say, ten thousand years from now, there can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electrodynamics. The American Civil War will pale into […]

Advances in Power over Ethernet ICs

July 26, 2018 By Lee Teschler Leave a Comment

Power-over-Ethernet specs have changed over the years — PoE devices have gotten more powerful, and so Ethernet cables are starting to become more like a power line. Silicon Labs’ John Wilson recently did a short video with us about four new power device ICs built with higher PoE power levels in mind. John reviewed demonstrations […]

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

September 22, 2016 By Aimee Kalnoskas Leave a Comment

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 […]
