The semiconductor device includes: a first transistor controlled by a control signal; a sense voltage generating circuit for sensing current flowing through the first transistor, mirroring current flowing through a reference current circuit, and summing the currents to generate voltage based on the summed currents; a reference voltage circuit for mirroring current flowing through the reference current circuit and generating reference voltage; an amplifier for comparing the voltage generated by the sense voltage generating circuit and the reference voltage; and a second transistor which has a gate connected to an output terminal of the amplifier and which can turn off the first transistor.
