Part Number: DRV10964EVM Other Parts Discussed in Thread: DRV10964 Dear Technical Support, Good day!
Customer is complaining the R2 resistor is not mounted in the board. Please check if R2 resistor should be mounted or not.
INVOICE#75920552 PART#595…
Correction!
I re-tested DRV10964 by sweeping the PWM input frequency from 15 kHz to 100 kHz at 50% duty cycle and did not notice any speed fluctuation.
We do not expect speed to fluctuate with change in PWM frequency.
Regards,
Vishnu.

I had a "Brushless Vibration Motor" and the datasheet is below:

Hi Lloyd,
There is a DRV10964EVM: https://www.ti.com/tool/DRV10964EVM
It seems that the problem is not that the DRV10964 will not attempt to spin the motor with PWM at 100% duty cycle but that the DRV10964 is failing to spin the motor with 100% duty cycle…
