Hello,

Could you please tell rise time and fall time requirement for SPI clock signal for DRV8889-Q1?

    Hello,

    This figure was inadvertently left out of the datasheet.  

    As long as the minimum setup and hold timing is maintained, the fall time (where the data is captured) just needs to be fast enough to ensure data is captured before SDI transitions.  It is a level triggered input, not edge triggered.  

    Regards,
