Classification: CPC H | IPC H

Claim 6:
7. The leakage protection circuit according to claim 6, wherein when a detection is started, the current detection signal is compared with the reference value; when the current detection signal reaches the reference value, a valid comparison result is recorded, and a cumulative counting is made; when the current detection signal does not reach the reference value, an invalid comparison result is recorded;
a discrimination number M is set, wherein if counting times of the valid comparison result reach M, no leakage phenomenon exists between the two input terminals; if the counting times of the valid comparison result do not reach M, the leakage phenomenon exists between the two input terminals; and
during the detection, if the invalid comparison result occurs, a cumulative counting result is cleared to zero.
