TIDA-00774: DRV8323

Part Number: TIDA-00774
Other Parts Discussed in Thread: DRV8323, , TIDA-01485, TIDA-010031


We are using DRV8323 motor driver in ‘1x PWM—Hall Effect Sensor’ mode for our design.  We have a requirement to calculate speed error from position feedback, i.e. from  BLDC Rotor position Hall Effect Sensor signals (HALL_A,  HALL_B,  HALL_C). Speed error is required by the speed controller logic in our design to generate modulated PWM.

Can you provide any reference design and sample code for the same.

We have also analyzed TIDA-00774 reference design’.
