A load driving apparatus receives an input voltage from a power supply, and supplies electric power to a load under processor control. The processor outputs first and second signals via first and second pins in a conjunction such that they are negated when the load is instructed to suspend operation. An output circuit supplies electric power to the load. A protection switch is provided on a driving path that extends from the power supply to the load and returns to the power supply. When the first signal is asserted (negated), a control circuit sets the output circuit to an operation state (suspension state). The control circuit turns on the protection switch on assertion of the second signal, and turns it off on negation of this signal.
