ABSTRACT:
An integrated circuit for driving a d.c. motor for use in a device, such as a toy car. The device include a noise filtering circuit, a pulse expansion circuit, a first oscillator, a second oscillator power voltage reset circuit, a constant voltage supplying circuit, a voltage detector, an inherent code input circuit, a right and left lamp driving circuit, a frequency dividing circuit, an inherent code detecting circuit, a received signal detecting circuit, an error signal detecting circuit, a comparator, a demodulator, a one-shot circuit, a servo-motor driving circuit, a speed variable driving circuit and an additional function driving circuit. Accordingly, a shared frequency can be utilized by a large number of people having an inherent code operably integrated. In addition, the variation of speed and position of the motor can be controlled in multi-steps, and the respective external elements can be minimized in size and erroneous device operation significantly reduced.
