A motor driven steering column system of a vehicle capable of interchanging tilt/telescopic modes using a single motor generating driving force by switching power transfer routes of the single motor using a small-sized motor in tilt/telescopic operations. The motor driven steering column system includes a driving motor generating rotational force for tilt/telescopic operations by receiving battery power according to a control signal of a mode control switch, an ECU selectively transferring the rotational force of the driving motor by determining the tilt/telescopic modes according to the control signal of the mode control switch, and a power switching unit controlled by the ECU for operating the motor driven steering column system in a selected mode.
