ABSTRACT:
A multi-level voltage detection circuit includes the comparators, the first resistors, the power signal input port and the or-gate. The first resistors and the power signal input port are electrically connected to the comparators. The or-gate is electrically connected to the outputs of the comparators. The or-gate outputs the power good signal according to the comparing result of the comparators.
