Working Principles

The UC2637N operates based on the principle of PWM modulation. It generates a variable duty cycle square wave that controls the average voltage applied to the motor, thus regulating its speed. By changing the duty cycle, the effective voltage across the motor terminals is adjusted, resulting in different speeds. The direction of rotation is controlled by the input signals IN1 and IN2, which determine the polarity of the applied voltage.
