    摘要: The power management circuit includes a sampling unit, a reference voltage unit, a comparator, and a power managing unit. The sampling unit divides an input voltage from the power supply to generate a sampling voltage. The reference voltage unit receives the input voltage and generates a reference voltage when the input voltage is larger than a predetermined value. The comparator compares the sampling voltage with the reference voltage, generates a first signal when the sampling voltage is larger than the reference voltage, and generates a second signal when the sampling voltage is smaller than the reference voltage. The power managing unit establishes an electrical connection between the power supply and the load according to the first signal, and cuts off the electrical connection between the power supply and the load according to the second signal.
