Abstract
A device and method for detecting a state of a load overcurrent protector are disclosed. The above-mentioned device includes: an input module (22), configured to be connected with two ends of the load overcurrent protector, and generate two output signals respectively at two output ends thereof; a high level signal gating module (24), configured to receive the two output signals generated by the input module (22), and gate and output a high level signal according to the above-mentioned two output signals; a low level signal gating module (26), configured to receive the two output signals generated by the input module (22), and gate and output a low level signal according to the above-mentioned two output signals; and a detecting module (28), configured to detect a voltage difference between the above-mentioned high level signal and the low level signal.
