Abstract
A semiconductor device includes: a first external terminal which receives an input voltage; a second external terminal which outputs a switch voltage; a third external terminal connected to a first ground; a fourth external terminal connected to a second ground; a first internal switch element formed on a semiconductor substrate to be connected between the first and second external terminals; a second internal switch element formed on the semiconductor substrate to be connected between the second external terminal and the third external terminal; and a control circuit connected to the fourth external terminal to drive at least one of the first internal switch element and the second internal switch element. The semiconductor substrate is electrically connected with the third external terminal rather than the fourth external terminal, and parasitic elements accompanied between the semiconductor substrate and each of the first internal switch element and the second internal switch element.
