Abstract
A protective circuit is provided. The protective circuit includes a charging unit, a voltage regulating unit, and a comparing unit. The charging unit receives a rise signal and an over-current signal, and outputs a first reference voltage. The voltage regulating unit receives the first reference voltage and adjusts an output voltage according, to the first reference voltage and a feedback voltage. The comparing unit receives the feedback voltage and compares the feedback voltage with a first threshold voltage to determine whether to output the rise signal to the charging unit.
