Abstract
A semiconductor device includes high-side and low-side switching elements connected in series to form a switching arm, a high-side driver IC for driving the high-side switching element, and, on a chip separate from the high-side switching element, a low-side driver IC for driving the low-side switching element. The driver IC includes a first controller for monitoring a switching voltage appearing at the node where the high-side and low-side switching elements are connected together. When a first driving control signal fed in from outside the semiconductor device instructs to turn on the high-side switching element, the first controller determines whether or not to permit the high-side switching element to be turned on based on a result of checking the switching voltage.
