2^32 would be enough, however, microamps would not be a good
representation for
this particular entry. For example, if the current limit is 2.1A the
entry will have to be 2100000.  Micro amps will not be the best
representation for this value from a scientific notation perspective.
Since the scale is in miiliamps as it is defined in the data sheet of
this device, it will be best to stay consistent since an error in
conversion
could cause serious problems.

Also, I really don¹t see why adding milliamps and millivolts as being a
major
problems since both of them are commonly used.
