Claim 2:
3. The overcurrent protection circuit according to claim 2, wherein the signal processing unit includes:
a noise reduction sub-unit, the noise reduction sub-unit being configured to receive the sample gate input signal output by the signal selection unit, perform the de-interference processing on the sample gate input signal, and output the de-interfered sample gate input signal;
an amplification sub-unit coupled to the noise reduction sub-unit, the amplification sub-unit being configured to receive the de-interfered sample gate input signal output by the noise reduction sub-unit, perform the amplification processing on the de-interfered sample gate input signal, and output the de-interfered and amplified sample gate input signal; and
a comparison sub-unit coupled to the amplification sub-unit, the comparison sub-unit being configured to receive the de-interfered and amplified sample gate input signal output by the amplification sub-unit, generate the first control signal according to the de-interfered and amplified sample gate input signal and the second preset voltage value, and output the first control signal.
