Abstract
Aspects of the present invention provides a device that is capable of accurately measuring an output current of a transistor, controls the drive of a switching element, by using an existing IC tester without any evaluation board improvement. The control device according to one aspect of the present invention has: a drive circuit, a plurality of transistors for controlling the drive of a switching element and a transistor operation controller. A transistor for turning the switching element OFF is configured by a plurality of transistors. The transistor operation controller, in a normal operation, performs ON/OFF control on the two transistors simultaneously or collectively by means of the same drive signal output from the drive circuit. In a test operation, the transistor operation controller sequentially selects one of the transistors and supplies the same drive signal to the selected transistor, to drive the transistors individually.
