Abstract:
A discharge circuit for an electronic device includes an energy storage element, a plurality of switches and a plurality of discharge paths coupled to the energy storage element and the switches. If a system power of the electronic device is turned off, a first switch of the switches conducts a first discharge path of the discharge paths, and the energy storage element is discharged through the first discharge path. In response that a voltage of the energy storage element drops to a first threshold, a second switch of the switches conducts a second discharge path of the discharge paths, and the energy storage element is discharged through the first discharge path and the second discharge path.
