Patent ID: 10181716

Abstract:
A hot-swap protection circuit includes: a hot-swap circuit, a hot-swap detection circuit, and an N-well generation circuit, where the hot-swap detection circuit is configured to detect whether hot-swap is performed on the hot-swap circuit, and feed back a detection result to the N-well generation circuit; and the N-well generation circuit is configured to receive the detection result fed back by the hot-swap detection circuit, and output a control signal according to the detection result, to protect the hot-swap circuit. The hot-swap detection circuit is used to detect whether hot-swap is performed on the hot-swap circuit, and the detection result is fed back to the N-well generation circuit, so that the N-well generation circuit outputs a control signal according to the detection result fed back by the hot-swap detection circuit, to protect the hot-swap circuit, thereby preventing the hot-swap of the hot-swap circuit from burning a host or a peripheral device.
