Hi Paul,
Sorry for the delay and thank you for your patience.
What are you configurations for the device regarding current sense? Such as GAIN?
Have you calibrated the Amplifier at all?
Regards,
Yara

Part Number: DRV8353 Hello,
We are using a DRV8353H to design a BLDC motor driver and have a few questions regarding the power supply recommendations
The external supply voltage range is 18-75V and we are using the dual power supply configuration with Vdrain…
Kirana,
Based on that screenshot, speed_Hz is zero. This should not be the case. Add "motorVars_M1.angleHall_rad" and "motorVars_M1.speedHall_Hz" to your debug view. Are they changing?
