Abstract
A semiconductor device driving circuit includes: a threshold adjustment circuit; a desaturation voltage detection circuit; and a drive circuit. The threshold adjustment circuit switches the threshold between a first voltage and a second voltage which is larger than the first voltage, outputs the first voltage as the threshold when the semiconductor switching device is in an off-state, and outputs the second voltage as the threshold when the semiconductor switching device is turned on and a voltage between the first electrode and the second electrode is a saturation voltage.
