DRV8880: Small current limit setting

Part Number: DRV8880


Customer thinks to use DRV8880.
Condition is full step and 20mA full scale current.
Is it possible?

DRV8880 operates the current setting value 71% with full step.
For the reason, I think that 30mA full scale current setting is better.

The concern is accuracy of the current limit detection.
I think that the accuracy is bad from Figure 10.

If it is possible on specification, I tell customer to try at EVM.

Best regards,
