Abstract
An over current protection circuit and an over current protection method thereof are provided. The over current protection method includes: generating a reference current curve; detecting an operation current of an electronic device; calculating a first average slope of the reference current curve and a second average slope of a variation curve of the operation current; and determining whether to activate an over current protection mechanism by comparing the first average slope and the second average slope during an over current detection mechanism.
