Abstract:
An EMP protection circuit with a counter has a surge protection circuit capable of suppressing EMP, and also use an extra counting circuit for sensing light emission or variation of magnetic force of the surge protection circuit to count the action times of the surge protection circuit, thereby warning that the surge protection circuit has reached its time-limit of use and has to be replaced. In this way, various kinds of electronic products can be more perfectly protected to avoid higher loss.
