Hi
My customer is using DRV8805.
He has a issue.
STEP signal is not inputed, But DRV8805 output voltage to motor.
Please see attached file which is detail waveform.
This event isn't to add a capasitor of 0.1uF "between the 1-Pin (VM) and GND" and "between the 2-Pin (VCLAMP) and GND".
What is the cause of this issue?
Could you advice me?
Best regards
Shimizu
