Can any one provide reference for DRV8850 . At input (IN1H IN2H AND IN1L IN2L) , the frequency i observed on cro is around 2 Khz .But at output i get 4.3 Khz . I am using feedback encoder for driving a stepper motor in this situation motor is rotating on full speed as on output frequency is larger , i am confused that at input frequency is around 2 Khz .Please help !

Thanks

This post does not seem to be about MSP430 but rather about the DRV8850 - so I have moved it to the Motor drivers forum where you will hopefully get better support.

Hi Shahrukh,

Are all inputs toggling? Can you provide a schematic?
Can you provide scope captures of the inputs versus the outputs?
