Patent number: 11321258Abstract: An integrated circuit includes a specific pin, an output circuit, a voltage detector, and a controller. The output circuit is coupled to the specific pin. The voltage detector obtains a detection voltage value from the specific pin. In response to an alert request, the controller provides a control signal to the output circuit based on the detection voltage value, so as to selectively control the output circuit to transmit the alert signal to the specific pin. When the control signal instructs the integrated circuit to operate in a blocking mode, the output circuit blocks the alert signal from being transmitted to the specific pin. When the control signal instructs the integrated circuit to operate in a transmission mode, the output circuit transmits the alert signal to the specific pin.Type: GrantFiled: September 2, 2020Date of Patent: May 3, 2022Assignee: NUVOTON TECHNOLOGY CORPORATIONInventors: Kang-Fu Chiu, Chih-Hung Huang, Chun-Wei Chiu, Hao-Yang Chang
