Abstract:
A safety shutdown apparatus with self-driven control is coupled to a power-supplying path between a power supply apparatus and a load. The safety shutdown apparatus includes a detection unit, a controllable switch, and a drive circuit. The detection unit is coupled to the power-supplying path, and the controllable switch is coupled between a positive node and a negative node of the power-supplying path. The drive circuit is coupled to the detection unit, the power-supplying path, and the controllable switch. The drive circuit receives an output voltage of the power supply apparatus to turn on the controllable switch, and turn off the controllable switch according to whether the detection unit detects a current flowing through the power-supplying path.
