DRV8818: Timing diagram

Part Number: DRV8818

Hi,

Could you provide correct timing diagram?

Enablen is active low but it seems to be active high in Figure. 1

Now when STEP is low, device drives output.

Need to compare timing diagram and board.

Thanks.

  • Hey David, 

    The outputs do transition at the rising edge of the STEP signal. 

    I believe you are correct about nENABLE being wrong, it should be LOW when driving a motor.  

    This chip is quite old (released 2011), if this is a new project design you may want to consider using a more modern driver such as the DRV8424.
