Abstract

A load device having a short-circuit protection function is disclosed which is capable of avoiding damage of a switching element such as an output transistor. The load device includes a switching element coupled to a load in series. The switching element operates in response to a drive signal. A power supply supplies a voltage across the series circuit of the load and the switching element. A voltage detection circuit detects a voltage exertion to the load and generates a voltage exertion signal. A short-circuit protection circuit interrupts supply of the drive signal to the switching element when no voltage exertion detection signal appears at the expiration of a predetermined period of time from initiation of the supply of the drive signal.
