ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,431,889, issued on Sept. 30, was assigned to POWER INTEGRATIONS INC. (San Jose, Calif.).
"Fast turn-on protection of a cascode switch" was invented by Rajko Duvnjak (Kanata, Canada).
According to the abstract* released by the U.S. Patent & Trademark Office: "Fast turn-on protection of a cascode switch is presented herein. A cascode circuit includes a depletion mode field effect transistor and an enhancement mode field effect transistor electrically coupled in cascode. During turn-on, a protection circuit detects an overcurrent fault by observing a plateau of a cascode node voltage. An overcurrent fault may be detected in response to the plateau existing for greater than a threshold ...
