Zusammenfassung: | A power reset circuit is provided. The power reset circuit has a first terminal coupled to a first power storage element and a second terminal coupled to a second power storage element and a load andincludes a discharging control circuit and a switching control circuit. The discharging control circuit induces a short circuit between the second terminal and the ground terminal when a supply voltage at the second terminal is lower than a reset voltage to provide a first discharging path. The switching control circuit provides a conduction path between the first and second terminals when the supply voltage is higher than an end-of-discharging voltage lower than the reset voltage. During a period when the supply voltage is lower than the end-of-discharging voltage, the switching control circuit cuts off the conduction path and provides a second discharging path between the first terminal and the discharging control circuit.
