Part Number: DRV8323
I designed the motor driver using DRV8323RH.
BOOSTXL-DRV8323RH circuit was referenced.
But I have a trouble in switching noise. So, I tried to shorten the path(GHx, GLx) from MCU to DRV8323.
And I use slow turn on time using low IDRVE.
Recently, I found the resistor in GHx, GLx path in TIDA-00774 18V/1kW circuit(below figure)
What is the role of resistor?
Can it reduce the switching noise in fast turn on time?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Thnak you, James.
I have designed the board to shorten the trace form DRV8323 and MOSFET.
But, I had a trouble in switching noise. So, I used low IDRIVE condition.
Can I have one more question?
What is better design in a view point of trace from DRV8323 to MOSFET.
1. short trace(maybe 25mm) with via.
2. long trace(maybe 40mm or over) without via
In reply to Min-su Kim:
Thank you for answer, James.
It will helpful for me.
