Abstract
Switch circuitry comprise a boosting circuit, a first switch, and a second switch. The boosting circuit boosts an input voltage. The first switch includes an input part to which the input voltage is applied, an output part which outputs an output voltage based on a voltage applied to the input part, and a driving part to which a driving voltage is applied, the first switch in which a voltage which the boosting circuit outputs is applied to the driving part and which outputs the output voltage based on the input voltage when the input voltage is higher than the output voltage. The second switch short-circuits the driving part of the first switch and the input part of the first switch when a value obtained by subtracting the input voltage from a voltage applied to the driving part exceeds a driving threshold.
