US Patent Issued to TEXAS INSTRUMENTS on Sept. 23 for "Bias generation for bridge driver load current sensing" (Indian Inventors)

ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,422,873, issued on Sept. 23, was assigned to TEXAS INSTRUMENTS Inc. (Dallas).

"Bias generation for bridge driver load current sensing" was invented by Venkatesh Guduri (Bangalore, India) and Ganapathi Shankar (Bangalore, India).

According to the abstract* released by the U.S. Patent & Trademark Office: "A load current sensing circuit includes a sense leg including a sense transistor with a gate coupled to the output of a high-side gate driver, a feedback transistor, and a sense resistor coupled in series between a power supply and ground. An amplifier has differential inputs coupled to the sense leg and to an output, and an output coupled to the feedback transistor gate. A bias circ...
