| description | A power supply control device includes a charge circuit charging a capacitor coupled to a second node with a full-wave rectified voltage input into a first node when activated, a first detection circuit detecting if the first node is less than a first voltage, a second detection circuit detecting if the second node is less than a second voltage and if the second node is equal to or higher than a third voltage higher than the second voltage, a discharge circuit discharging an electric charge accumulated in the first node by activation, and a control circuit activating the charge circuit when the voltage of the first node is less than the first voltage, activates the discharge circuit when the second node is less than the second voltage, and deactivates the discharge circuit when the voltage of the second node is equal to or higher than the third voltage. |
