Tsui-Chuan CHUANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Protection circuit applied to electronic device and associated protection method
    Patent number: 11545822
    Abstract: A protection circuit, and related method, for an electronic device including a first power output interface and a second power output interface is disclosed. The protection circuit includes a first switch element, coupled between a first voltage source and the first power output interface. The detection circuit being operation to detect an output voltage value of the second power output interface to generate a detection result. The first switch element, according to the detection result, connects the first voltage source to the first power output interface to allow the first power output interface to output power to an external terminal, or disconnects the first voltage source from the first power output interface.
    Type: Grant
    Filed: April 13, 2021
    Date of Patent: January 3, 2023
    Assignee: MEDIATEK INC.
    Inventors: Tsui-Chuan Chuang, Ming-Ruei Liu, Dien-Shen Chiang, Chien-Tai Kao
