A rotating electric machine driver apparatus and an electric power steering apparatus using the same includes a controller section that obtains a detected current value and generates a high-side instruction signal and a low-side instruction signal to switch an upper arm element and a lower arm element based on the detected current value. An abnormality detector determines a simul-OFF abnormality which is an abnormality of a pair made up of the high-side and low-side instruction signals being simultaneously switched off based on a condition that switching off of the high-side instruction signal for the upper arm element and the low-side instruction signal for the lower arm element pair continues for at least a simul-OFF abnormality determination time. In such manner, the simul-OFF abnormality of the instruction signals is detected.
