Tool/software:
We use TPL7407LA-Q1 to drive the stepper motor (12V, unipolar, 120Ω), but the output waveform is abnormal, please help to analyze it. The circuit diagram is shown below,
the input and output waveform page is shown below too, yellow is the PWM input signal (IN1), green is the output waveform of OUT1, theoretically when IN1 is low, OUT1 should be high level, how can there be a wave-like waveform.
