Abstract
A leakage current detection and interruption (LCDI) device for a power cord includes a switch unit configured to control an electrical connection between an input end and an output end, and a leakage current protection unit, which includes a switch drive module and a leakage current detection module. The leakage current detection module includes first and second leakage current detection lines coupled in series. The switch drive module is configured to control the switch unit based on a leakage current signal generated by the leakage current detection module to disconnect the electrical connection. The LCDI device can detect whether the first and second leakage current detection lines are intact, thereby ensuring the reliability of the device.
