Patent number: 11588317Abstract: A ground fault circuit interrupter is provided, including a sensor module, a leakage protection module, a self-test module and a tripping module. The sensor module is configured to generate a sensor current according to a detection signal. The leakage protection module is configured to: generate a trip driving signal in a detection stage according to the sensor current; and generate a trip driving signal in a non-detection stage after the self-test module has a fault. The self-test module is configured to generate the detection signal in the detection stage, and determine that the leakage protection module does not have a fault if the leakage protection module generates the trip driving signal. The tripping module is configured to respond to the trip driving signal generated in the non-detection stage to disconnect a load from a power supply circuit, and not respond to the trip driving signal generated in the detection stage.Type: GrantFiled: December 15, 2020Date of Patent: February 21, 2023Assignee: Shanghai Fudan Microelectronics Group Company LimitedInventors: Shusen Hao, Yang Liu, Chunyong Wu, Jiwen Gong
