DRV8718-Q1: DRV8718-Q1 current sense accuracy

Hi Team,

Could you please kindly help to check what is the accuracy for the current sense of DRV8718-Q1? How customer evaluate the accuracy of the current sense? 

If customer want to detect four motors current, do we have reference design for this kind of application? Thank you very much for your support.

Best regards

Jie
