DRV8849: Generation of Sinusoidal wave at the output of DRV8849 Driver.

Part Number: DRV8849

Tool/software:

Hi ,
We tested the waveform at a lower Vref value i.e. of 50 (0.65V) , and we observed that it is still not purely sinusoidal.

Interestingly, a pure sine wave is observed only at a Vref value of 0.
Kindly review and let us know your feedback.

Please see the attached waveform for reference.

Here, Vref is 0.65v and supply voltage is 12v. 

Here, Vref is 0v and supply voltage is 12v.

Vref is 0 ie. 0v & supply voltage is 12v
