ALEXANDRIA, Va., Aug. 6 -- United States Patent no. 12,381,473, issued on Aug. 5, was assigned to Infineon Technologies Canada Inc. (Ottawa).
"Driver circuit for a power transistor" was invented by Arvind Sivakumar (Plano, Texas) and Yinglai Xia (Plano, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "A driver circuit for a power transistor. The driver circuit allows for robust turn-off of the power transistor, and for reduced power losses when the power transistor transitions back on. The driver circuit controls what voltage is applied to the gate terminal of the power transistor. The driver circuit prevents unintended turn-on of the power transistor by applying a negative voltage to the gate terminal o...
