摘要:
Provided is a low-power direct current detector. The low-power direct current detector includes a main current source circuit generating an ultra-low current, a limitation circuit limiting the current generated by the main current source circuit to lower than a preset current, and a voltage detection circuit biased by the ultra-low current generated by the main current source circuit to detect an input DC voltage.
