US Patent Issued to Shanghai Huali Integrated Circuit on June 24 for "Multilevel voltage detector circuit" (Chinese Inventors)

ALEXANDRIA, Va., June 25 -- United States Patent no. 12,340,854, issued on June 24, was assigned to Shanghai Huali Integrated Circuit Corp. (Shanghai).

"Multilevel voltage detector circuit" was invented by Yu Jia (Shanghai) and Yifei Qian (Shanghai).

According to the abstract* released by the U.S. Patent & Trademark Office: "The present application discloses a multi-level voltage detector circuit. The voltage dividing circuit includes a first resistor string and a second circuit. The first resistor string is formed by n+1 voltage dividing resistors connected in series and outputs n divisional voltages. The second circuit provides n lower voltage dividing resistors. A kth lower voltage dividing resistor detects kth rise and fall detection ...
