DRV8353: Drv8353 Driver goes into fault when using internal state table

Hi Tobias,

Thank you for your question. Are you able to provide information regarding what is different with your system between when it worked and now? Were you using the 1x PWM previously with the Hall Sensor inputs, or are the sensors a new addition to the system? Has the power input to the system or the PWM control input changed in any way? This information will help me try to locate the source of the fault signal.

Best,

Davis

I havent changes anything in the hardware, the system was tested in both states with a 4s  lipo and a 12s lipo... i had a phase connection disconnect under light load. The sensor stayed the same at all points in time. I changed some minor stuff from my code, but nothing that did pwm or something similar changed functionally inbetween

Thank you for the information. The setup looks fine, so I recommend following this FAQ to determine the source of the fault flag being set by the device: https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1160331/faq-debugging-faults-with-hardware-variant-devices?tisearch=e2e-sitesearch&keymatch=hardware%20fault#. Please let me know if this helps solve your question.
