動回路。 It has a switching means that controls energization to an on-board load connected in series with the battery by operating a switch in response to a control signal from a control circuit, and the driving current to the load is cut off by the switching means. In an automobile load drive circuit equipped with a current feedback path for dissipating a back electromotive force sometimes generated in the load, a control signal from the control circuit is used as an input signal to send a current flowing through the current feedback path to the switching means as a drive current. A load drive circuit for an automobile, characterized in that it is provided with an output means for outputting an output.
