Title:
REVERSE CONNECTION AND CURRENT BACKFLOW PREVENTION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/076294
Kind Code:
A1
Abstract:
A reverse connection and current backflow prevention circuit comprises a voltage input end (VCC); a voltage output end (VOUT); a control circuit (10) for outputting a first control signal or a second control signal; a switch circuit (20), which is switched on when the first control signal is received, and is switch off when the second control signal is received; and an output circuit (30). When a first input end is connected to a positive electrode of a power supply and a second input end is connected to a negative electrode of the power supply, the power supply outputs a voltage to a back-end circuit; and when the first input end is connected to the negative electrode of the power supply and the second input end is connected to the positive electrode of the power supply or the power supply is in a short circuit, the voltage and the backflow current are not provided to the back-end circuit.
