摘要： The present disclosure provides a hot-swap circuit and a control apparatus. The hot-swap circuit includes: a power input terminal, a power output terminal; a startup module electrically connected to the power input terminal and the power output terminal; a switch module electrically connected to the power input terminal, the power output terminal, and the startup module; a detection module electrically connected to the startup module, the switch module, and the power output terminal. When a surge signal is input at the power input terminal, a voltage value of a first control signal output by the detection module doesn't fall in a voltage value range of a preset first control signal, then the switch module is controlled to be turned off, so as to cut off a power signal input to the power output terminal, reducing probability of circuit damage, and reducing sparking phenomena of hot-swap power interfaces.
