Semiconductor device, electronic device, and vehicle

Abstract

A semiconductor device includes: an output transistor of a split-gate type configured to have a plurality of channel regions controlled individually according to a plurality of gate control signals; an active clamp circuit configured to limit the terminal-to-terminal voltage across the output transistor to or below a predetermined clamp voltage after a control signal turns to a logic level requesting the output transistor to be off; a delay circuit configured to generate a delayed internal signal by giving a predetermined delay to an internal signal indicating whether the terminal-to-terminal voltage across the output transistor is higher than a predetermined threshold voltage lower than the clamp voltage; and a gate control circuit configured to control the plurality of gate control signals individually so as to raise the on resistance of the output transistor according to the delayed internal signal.
