DRV8323R: BLDC Motor Driver Schematic & BOM Review Request

VOLKAN YARDIMCI

Part Number: DRV8323R
Other Parts Discussed in Thread: DRV8320, DRV8323

Tool/software:

Hi TI Community,

I would like to share our DRV8323RS BLDC Motor Driver schematic so that you can review it and see the deficiencies and suggestions, if any.

Specs of design;

Max Supply: 12.6V - 20A (3S Lithium-Ion)

Motor Type: BLDC Ducted Fan Motor (2 Pole)

Requested RPM: +60.000 RPM

MCU: STM32G4

Drive Method: Trapezoidal

Configuration: 3x PWM

As I specified the main driver method will be trapezoidal above, however we also would like to try FOC for a few specification, that's why we used DRV8323 instead of DRV8320.

I've attached schematic as PDF and BOM as CSV/XLSX.

Kind Regards,

Volk

Hi Volk,

I looked through the schematic with the team and we did not notice any issues with the schematic.

When doing the PCB layout, please refer to this app note for best practices:
