ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,525,922, issued on Jan. 13, was assigned to PSEMI Corp. (San Diego).
"Over temperature protection with soft shutdown for power amplifier" was invented by Shota Ishihara (San Diego).
According to the abstract* released by the U.S. Patent & Trademark Office: "Various methods and circuital arrangements for protection of a power amplifier from over temperature are presented. According to one aspect, a protection circuit coupled to a temperature sensor controls a biasing current or voltage to the power amplifier to limit a power dissipation through, and therefore a temperature of, the power amplifier when a high limit temperature is sensed. When the high limit temperature is sensed, the b...
