More Information
Summary:The invention provides a power supply short circuit protection circuit, which comprises a power supply, a detection circuit, and a switching circuit, wherein the power supply is used for providing working voltage signals; the detection circuit is connected with the power supply and a load for detecting whether short circuit happens to the load; the working voltage signals outputted by the power supply are transmitted to the load via the switching circuit, supply of the working voltage signals for the load is cut off under control of the detection circuit when the load is short-circuited, and supply of the working voltage signals for the load is automatically recovered when the short circuit state of the load is eliminated. Short circuit protection in the condition without a diode, a fuse and the like can be realized, and the cost is low.
