ABSTRACT:
The present invention relates to an integrated circuit for driving a d.c. motor with radio control comprising a receiving circuit for receiving and detecting certain signals transmitted from a transmitter, an amplifier for amplifying an output signal of said receiving circuit, a peak detector for converting the said amplified audio signal into a d.c. voltage, a comparator which have a hysteresis character dependent on the output level of the peak detector, a voltage regulating circuit supplying a stabilized voltage into all other components, and a direction control circuit to generate logic control signals deciding actual operation mode of the d.c. motor and motor driving circuits to produce motor driving signals by the output signal of the direction control circuit.
