    possible reasons for a PWM that stops sporadically for different lengths of time

      Thanks for your help and time!

       

      My error pattern, in my full-bridge sets sporadically and for a different duration. see images

      The following steps were taken to minimize variable errors:

      -new project: with only one PWM for which two pins are connected. All other pins connected to the chip on the PCB are digitally zeroed.

      - I modified the PCB so that PWM pins see an open trace.

      - all VCC voltages were measured and remained stable at 4.7V even during the PWM failure.

      All simplification didn't change the behaviour.

       

      Is it there something else what I could try?
