Provided is a load drive device comprising: a first input terminal for accepting an input of a first input current from a power source; a second input terminal for accepting an input of a second input current from the power source via an external resistor; an output terminal for outputting an output current to a load; a current distribution unit for summing the first input current and second input current at a prescribed distribution ratio and generating the output current and a control unit for controlling the distribution ratio. As one example, it would be appropriate for the control unit to control the distribution ratio according to the difference between a first terminal voltage present in the second input terminal and a second terminal voltage present in the output terminal.
