Part Number:DRV8323
TI DRV83323 data sheet (SLVSDJ3A), pages 60 & 66, the application notes show the PGND and AGND with the same ground symbol and then a second symbol that has not been defined! Would you please clarify?
I would like a recommendation relating to grounding of the analog and the power components used in conjunction with the DRV8323S driver(I have concerns on noise from ground bus). From a technical aspect, how are the grounds different within the driver?
Background:
Using DRV8323S driver to drive a 14A BLDC motor at 18V nominal. Feedback is supplied by the motor Hall sensors. The motor is changing directions often.
