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. The power reset circuit includes a discharging control circuit and a switching control circuit. The discharging control is coupled to the second terminal and a ground and configured to short the second terminal and the ground during a period in which a supply voltage at the second terminal is lower than a reset voltage to provide a first discharge path. The switching control circuit is coupled to the first terminal, the second terminal, and the discharging control circuit and configured to a turned-on path between the first terminal and the second terminal during a period in which the supply voltage is higher than a discharging-stopped voltage. The discharging-stopped voltage is lower than the reset voltage. During a period in which the supply voltage is lower than the discharging-stopped voltage, the switching cont |
