Dears,

    My customer want to know the timing requirements of Enable,Sleep, APHASE,BPHASE, which is similar to the screenshot of DRV8825. I can't find this in the datasheet.Could you pls help? Thanks.

    Hi Jon,

    The timing requirements between these two devices will be different due to the different interface types. The DRV8812 has a PH/EN interface while DRV8825 has a STEP/DIR interface.

    The DRV8812 has an internal PWM frequency of 50kHz. 

    Is the customer having trouble implementing a specific step sequence?

    Best,

    David
