Abstract

An object of the present invention is to reduce a chip area of the high-side driver circuit. A high-side driver circuit of the present invention is a high-side driver circuit in which a first potential is set as a power supply potential, which includes a constant voltage circuit configured to operate with a second potential as a reference potential, and generate, from the first potential, a third potential which is lower than the first potential and higher than the second potential, a logic circuit configured to operate with the third potential as a reference potential, a level shift circuit configured to shift the reference potential of the output signal of the logic circuit from the third potential to the second potential, and a driver circuit in which the second potential is set as a reference potential, and configured to drive a switching element by the output signal.
