Abstract
A load control device includes a power supply terminal connected to a power source via a fuse, a load driver configured to drive loads by electric power supplied from the power source via the fuse and the power supply terminal, a current detector configured to detect load currents that flow through the loads, respectively, and a controller. The controller is configured to calculate a total current that flows through the fuse based on the load currents detected by the current detector, calculate a physical quantity correlating with the total current and related to a connecting member that connects between the fuse and the power supply terminal in response to that the total current is equal to or higher than a predetermined current value, and limit at least one of the load currents in response to that the physical quantity is equal to or greater than a reference value.
