Abstract
A power-off control circuit applied in an electronic device includes a switch, a first control unit, a first buffer unit, a second control unit, and a second buffer unit. A first control unit coupled to the second terminal of the switch. The first control unit receives a first logic signal when the switch is pressed, and outputs a first control signal. A first buffer unit is coupled to an output of the first control unit to receive the first control signal, and outputs a second control signal. A second buffer unit is coupled to the second terminal of the switch to receive the first logic signal, and outputs a third control signal. A second control unit is coupled to an output of the second buffer unit to receive the third control signal, and outputs a power-off control signal to make the electronic device to power-off.
