Abstract:
1. A power control device for an electronic device, comprising: a power switching unit, for switching to output a direct current (DC) power source to a load of the electronic device according to a power switching signal; a switching detection unit, for responding to a power switching status to generate a switching detection signal; a status latch module, for generating the power switching signal according to the switching detection signal, a first status signal and a second status signal, comprising: a logic unit, for generating the first status signal and the second status signal for the status latch module according to the power switching signal, such that the status latch module latches the first status signal and the second status signal; wherein the first status signal and the second status signal are used to control the first status latch unit or the second status latch unit to adjust the power switching signal according to the switching detection signal.
