DRV8886: Regulation Current Limitation Confirmation

Part Number: DRV8886

Hello team!

I'd like to confirm my understanding is correct or not since I got the question from the customer.

1: Ifs can be set by resistor 15k ~ 300kohm, and Ifs value would be 0.015 to 2.0A based on fig11?

2: When it comes to estimating Ifs accuracy, we only consider AREF accuracy & RREF resistor tolerant?

Best Regards,

  • Kitajima-san,

    Thank you for your post.  

    You are correct on both points.  

    For current less than Ifs during micro-stepping, for example, please see the table in the datasheet page 7.  "Current Trip Accuracy".

    Ryan-san,

    Understood!

    Also thank you for adding the comment about current trip accuracy.

    Best Regards,
