Abstract
The present invention relates to a linear integrated circuit for driving a d.c. motor with remote radio control comprising an amplifier B.sub.1 to amplify the signal transmitted by the transmitter, a peak detector B.sub.2 detecting the said signal, a comparator B.sub.3 triggered by the d.c. output voltage of the said detector, transistors Q.sub.1 ', Q.sub.2 ' of the driving stage circuit B.sub.4, which can invert the driving direction of the d.c. motor by on or off operation of the said transistors in accordance with the output voltage of the said comparators, a voltage regulator circuit B.sub.5 and a thermal protection circuit B.sub.6 stabilizing the said transistors thermally.
