Abstract
A load drive circuit is configured to control driving of an electric load that is a direct current load, and includes a controller, a switching element, and a current detection portion. The controller generates and outputs a control signal for controlling a flowing state of a load current that flows to the electric load. The switching element switches flowing and interrupting of the load current based on the control signal. The current detection portion detects the load current. The controller includes a type determination portion and a control signal output portion. The type determination portion determines a type of the electric load based on the load current detected by the current detection portion. The control signal output portion generates and outputs the control signal based on the type determined by the type determination portion.
