Claim 6:
7. The overcurrent protection circuit according to claim 1, wherein the delay determination sub-circuit includes:
a delay unit, the delay unit being configured to receive the first control signal output by the sampling sub-circuit, delay the first control signal for the first preset time, and output the delayed first control signal; and
a determination unit coupled to the delay unit, the determination unit being configured to: receive the first control signal output by the sampling sub-circuit and the delayed first control signal output by the delay unit; determine whether the voltage value of the first control signal before the delay is equal to the voltage value of the first control signal after the delay; and if the voltage value of the first control signal before the delay is equal to the voltage value of the first control signal after the delay, output the counting signal.
