Hi Ti Team:

Can you please tell me, if we are using 3.5mΩ here, what is the lowest accuracy of current that can be measured, here VBUS is 4.3v, looking forward to your reply!

    Hi,

    We offer a tool exactly for this purpose. Please download at this link. With this tool, you could visualize output error (accuracy) over the entire current range.

    You can also key in shunt resistor tolerance to have it accounted for.

    I assumed a shunt tolerance of 0.5% and here is what I got:
