A power-on circuit and an electronic device, which relate to the technical field of communications and are used for powering on the electronic device when the electronic device is in a power-off state. In the power-on circuit, one end of a first switch unit (2) is connected to an input end of a first conversion unit (3). An output end of the first conversion unit (3) is connected to a first input end of an AND gate (6). One end of a second switch unit (5) is connected to a second input end of the AND gate (6), and the other end of the second switch unit (5) is grounded. An output end of the AND gate (6) is connected to a controller (4). When the state of the first switch unit (2) is changed, the first conversion unit (3) outputs a first signal to the AND gate (6), so that the AND gate (6) outputs a power-on triggering signal to the controller (4), and the controller (4) executes a power-on operation according to the power-on triggering signal. When the state of the second switch unit (5) is changed, the AND gate (6) outputs a power-on triggering signal to the controller (4), and the controller (4) executes a power-on operation according to the power-on triggering signal. |
