BD9576MUF provides over-current protection and detection. Current
is
measured as voltage loss over external FET. Allow specifying FET's
on
resistance so current monitoring limits can be converted to
voltages.

We have '-ohms' and '-micro-ohms' already. Neither range works for
you?

Thanks for taking a look at this :)

I expect values to be magnitude of few hundred milliohms - which means
micro-ohms should be usable. I'll try to still check this as I am far
from being HW-expert. I probably can convert this to micro-ohms for v2.
