ABSTRACT:
A load detection apparatus which can be used for detecting loads of various kinds of peripheral devices. The present apparatus utilizes a compared result of a load potential and a reference potential to generate a high/low level signal output to adjust the load potential and make the load potential thus have a small fluctuation to achieve the purpose of load detection and maintain the peripheral devices working normally and uninterruptedly. The present apparatus can be used for detecting loads of various kinds of peripheral devices by properly choosing and replacing the values of the reference potential and other circuit element quantities.
