HEF4752V-AC Motor Control Circuit
HEF4752V is an AC circuit motor speed control utilizing LOCMOS technology. The circuit synthesizes three of these 120° phase signals with a sinusoidal frequency range of 0 to 200 Hz for the average voltage versus time. The method is based on the principle of pulse width modulation to achieve sufficient accuracy of the output voltage over the entire frequency range. One is the use of pure digital waveform generation. Push-pull type for all outputs. Inputs and outputs are variously protected against the effects of static electricity in the handling of the device. However, to be completely safe, it is advisable to take the necessary precautions into consideration.
