Part Number: DRV8323R
Other Parts Discussed in Thread: CSD88599Q5DC, CSD88584Q5DC, CSD87334Q3D

Hi TI Team,

I'd like to see if you could give this design a quick glance to see if I missed out on any important connections within the schematic, I was following the design guidelines of your spec sheets and application notes.

Specs of the design:

  • 20A Max at 26.7 V MAX
  • Single shunt resistor sensing, using only one current sense amplifier (SOA) to sense motor current
  • The DC-DC Switch regulator of the DRV device will supply the system with 3.3V at150mA MAX
  • 1xPWM Configuration
  • DRV is controlled/communicates with by an external MCU. 

Please let me know if you have any feedback or any more questions. I'll supply and respond as fast as I can.
