Abstract
The present disclosure provides a short-circuit protection apparatus and method. The short-circuit protection apparatus includes a current detection circuit, a control circuit, and a voltage detection circuit. The current detection circuit detects an output current of an output circuit and outputs a current detection signal when the detected current is greater than a preset current. The control circuit receives the current detection signal and controls the output circuit to be turned off The voltage detection circuit detects an output voltage of the output circuit. When the output voltage is not in the preset voltage range, the output voltage is detected continuously When the output voltage is in the preset voltage range, the control circuit receives the voltage detection signal for controlling the output circuit.
