  RE: DRV8353: SRM motor control with hall sensor

  Hello Kaarthi, When the duty cycle truncation happens, does the nFAULT pin pull low? Can you capture nFAULT, INHx, GHx, and SHx on the same oscilloscope screen to see the behavior? If nFAULT is toggling then you are hitting over current, either the...

  RE: DRV8353: The gate driver does not work. FAULT condition all times

  Dear Cole, Thank you very much for your support, finally I found the problem! I checked all values in the table, all OK except Vsp (SEN_OCP). Solution: Our configuration has 2 shunt resistors (not 3 as DRV8353 has the capability). The third...

  RE: DRV8353: Problems with newer Batch NR. TI98F TI99F

  Hello Jörn, Thanks for the waveforms. I actually think this is the same symptom as you mentioned before. When I think of ripple caused by gate drive current, I expect the ripple and overshoot to occur at the end of the transition from high to low...

  RE: DRV8353: DRV8353H Gate driver Fault issue

  Hey Kumar, Have you verified the fault table and ruled out possibilities of what fault shouldn't be triggering? Check the table below. While "power supply discontinuity" is not very specific in context of the device, I'm going to...

  RE: DRV8353: DRV8353 Ground Pad or Thermal Pad

  Hello Kumar, I suspect failing means damage? We recommend to connect GND to the thermal pad. This illustrated by the pink outline I've given to the Layout Example (Figure 75) given in the datasheet. There are many reasons, beyond just thermal...

  RE: DRV8353: Overcurrent causes the device damaged

  Hello User5066232, Assuming that, motor wire short circuit test means, phase wire of motor that is attached to the phase node, which is SHx, is attached to GND during operation, we know that a high side FET (which means a GHx is high), and the current...
