Abstract
Disclosed is a power semiconductor device including a bootstrap circuit. The power semiconductor device includes a high voltage unit that provides a high voltage control signal so that a high voltage is output; a low voltage unit that provides a low voltage control signal so that a ground voltage is output, and is spaced apart from the high voltage unit; a charge enable unit that is electrically connected to the low voltage unit and charges a bootstrap capacitor for supplying power to the high voltage unit when the high voltage is output, when the ground voltage is output; and a high voltage cut-off unit that cuts off the high voltage when the high voltage is output so that the high voltage is not applied to the charge enable unit, and includes a first terminal electrically connected to the charge enable unit and a second terminal electrically connected to the high voltage unit.
