US 2014/0157018 A1 · POWER MODULE AND ELECTRONIC DEVICE

Abstract

A power module to power a function module of an electronic device is provided. The power module includes a power unit, a switch unit, a timing unit, and a control unit. The switch unit is connected between the power unit and the function module, and establishes or cuts off a connection between the power unit and the function module. The timing measures a time has elapsed according to a timing length. The control unit is connected to the timing unit and the switch unit, and is used to start the timing unit to measure time after the electronic device has been turned on. The timing unit produces a trigger signal when the measured time reaches the timing length, the control unit turns off the switch unit when receiving the trigger signal, thus cutting off connection between the power unit and the function module.
