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 16):
A drive system, comprising:\n a rectifying circuit, configured to rectify an external AC voltage and output the rectified external AC voltage to a power supply bus on which a load is located; a switch circuit, arranged on the power supply bus, and configured to control the power supply bus to be in a conductive state or non-conductive state; a linear compensation circuit, configured to output a linear compensation signal to the switch circuit based on an acquired electric signal reflecting a power supply bus voltage, such that the switch circuit drives the load based on the linear compensation signal during a period in which the switch circuit is not in a forcible non-conductive state; and the protection circuit of  claim 1 , connected with the switch circuit, and configured to control the switch circuit to maintain the forcible non-conductive state within a protection period.
