Abstract
A protection circuit including a voltage dividing circuit, a first comparator, a first switch, a second comparator, and a delay and logic circuit is provided. The voltage dividing circuit generates a first divided voltage and a second divided voltage based on a power voltage. The first comparator is configured to compare a reference voltage and the first divided voltage to generate a first comparison result. The second comparator is configured to compare the reference voltage and the second divided voltage to generate a second comparison result. The delay and logic circuit receives the first comparison result and the second comparison result. Wherein, according to a plurality of different states of the first comparison result and the second comparison result, the first switch is turned on to conduct part of current of the power voltage to a reference voltage terminal, or the first switch changes from turn-on to turn-off.
