Abstract:
The present disclosure provides a protection circuit, a drive system, a chip and a circuit protection method, and a drive method. The protection circuit can be used in a circuit system in which a load is driven by a switch circuit, and acquire a voltage signal reflecting the voltage of a power supply bus on which the load located and generate a detection signal, and control the switch circuit to maintain a forcible non-conductive state within a protection period when detecting that the voltage of the detection signal satisfies a preset voltage warning condition. The present application solves the problem of circuit protection of DC-powered electronics in the prior art.

Claim (Index 8):
The protection circuit of  claim 1 , wherein, the control unit comprises:\n a delay control module, connected with the output terminal of the detection unit, and configured to output a first control signal when the received detection result indicates that the preset voltage warning condition is satisfied, start a delay timing based on the detection result output by the detection unit, and output a second control signal after the delay timing exceeds the protection period; and a switch circuit control module, connected with an output terminal of the delay control module and the control terminal of the switch circuit, and configured to control the switch circuit to turn to and maintain the forcible non-conductive state based on the first control signal, and release from the forcible non-conductive state based on the second control signal.
