ALEXANDRIA, Va., Sept. 3 -- United States Patent no. 12,407,344, issued on Sept. 2, was assigned to TEXAS INSTRUMENTS Inc. (Dallas).
"Transistor short circuit protection" was invented by Cetin Kaya (Plano, Texas), Nathan Richard Schemm (Rowlett, Texas) and Yong Xie (Plano, Texas).
According to the abstract* released by the U.S. Patent & Trademark Office: "A short circuit detection circuit includes a current terminal, a sense resistor, an amplifier, and a resistor-capacitor ladder. The sense resistor is coupled to the current terminal, and is configured to develop a sense voltage proportional to a current through the current terminal. The amplifier is coupled to the sense resistor, and is configured to generate a scaled current proportiona...
