PROBLEM TO BE SOLVED: To provide a driving device having a current detection function and a motor driving device having the current detection function capable of detecting current without lowering of voltage by using a dummy transistor connected in parallel to a drive transistor.SOLUTION: A driving device having a current detection function and a motor driving device having the current detection function includes: a driving unit provided with at least one transistor connected between a driving power source end for supplying a driving power source and a grounding and driving an instrument set beforehand by being switched by a switching control signal from at least one transistor; and a detection unit provided with at least one dummy transistor connected in parallel to at least one transistor, switched along with at least one transistor by the switching signal and detecting the current flowing to at least one dummy transistor. |
