1. An electronic device comprising:

  • a switching element having a control terminal and being driven by a voltage at the control terminal;

    an ON-drive switching element electrically connected to the control terminal of the switching element and configured to charge the control terminal of the switching element with electrical charge by the ON-drive switching element being turned ON;

    an OFF-drive switching element electrically connected to the control terminal of the switching element and configured to discharge electrical charge from the control terminal of the switching element by the ON-drive switching element being turned ON; and

    a control circuit that controls the voltage at the control terminal of the switching element and drives the switching element, by controlling the ON-drive switching element and the OFF-drive switching element based on an inputted drive signal to the control circuit,wherein the control circuit is configured to turn OFF a switching element using a time drive circuit other than the OFF-drive switching element after an elapse of a predetermined period of time from a timing at which the drive signal switches from an ON instruction thereof to an OFF instruction thereof, the ON instruction giving an instruction to turn ON the switching element, the OFF instruction giving an instruction to turn OFF the switching element.
