Abstract
A voltage detection system includes a first voltage detector and a second voltage detector. The first voltage detector is configured for detecting whether an input voltage reaches a first voltage level. The second voltage detector, coupled to the first voltage detector, is configured for detecting whether the input voltage reaches a second voltage level. The first voltage detector outputs a control signal to control a status of the second voltage detector according to a detection result of the first voltage detector.
