Abstract
A driving device of a semiconductor device includes a plurality of protection factor detection units, an identification signal generation unit, a continuation signal generation unit, a signal selection unit, and an alarm signal output unit. The protection factor detection units detect an occurrence of a protection factor. The protection factor requires a protection operation of a semiconductor device. The protection factor detection units output a protection factor generation signal. When any protection factor detection units output the protection factor generation signal, the identification signal generation unit generates a protection factor identification signal. The continuation signal generation unit generates a protection factor continuation signal while the protection factor detection unit outputs the protection factor generation signal. The signal selection unit selects the protection factor identification signal and the protection factor continuation signal. The alarm signal output unit outputs a selection signal selected by the signal selection unit as an alarm signal.
