Abstract
A power supply management circuit includes a first contact receiving a transmitted voltage, a second contact outputting the transmitted voltage, a relay coupled between the first contact and the second contact, a discharge unit coupled to the relay in parallel, and an activation unit coupled to the discharge unit. When the power supply management circuit receives a control signal, the discharge unit is turned on or off, and the relay enters into a switching procedure. When the control signal is an ON signal, the activation unit generates a driving voltage to turn on the discharge unit, the relay enters into a turn-on procedure, and the transmitted voltage is transmitted to the second contact through the discharge unit; after the switching procedure is completed, the activation unit stops generating the driving voltage to turn off the discharge unit, and the transmitted voltage is transmitted to the second contact through the relay.
