Abstract
A semiconductor device includes: a first terminal inputting a first voltage from outside; a drive unit using the first voltage as a power supply voltage and outputting a drive signal; a switching device driven by the drive signal; a second terminal separated from the first terminal and inputting a second voltage from outside; a comparator using a voltage generated from the second voltage as a power supply voltage and outputting an output signal when a voltage generated from the first voltage is less than or equal to a reference potential; and a shut-off switch shutting off a transmission of the drive signal to the switching device from the drive unit in response to the output signal.
