1. A semiconductor integrated circuit comprising:

  • a high-side transistor connected to a first reference potential;

    a low-side transistor connected to a second reference potential;

    a level shift circuit for driving the high-side transistor; and

    a pre-driver circuit for driving the low-side transistor,wherein a connection point of the high-side transistor and the low-side transistor serves as an output terminal,the level shift circuit has first and second N-type MOS transistors whose gates are driven by the pre-driver circuit, andthe semiconductor integrated circuit further comprises a diode whose anode is connected to the drain of the first or second N-type MOS transistor to which the gate of the high-side transistor is not connected, and whose cathode is connected to the output terminal.
