The Gecko G201 can be set for 0.3 to 7.0 Amps by a resistor. So, you
can set the nominal phase current to the exact value you need. 1 Amp
would be set with a 7.8 K Ohm resistor. I do not understand your
lower limits comment. The Gecko can be set for exactly 1 A. It is
not a 0.3 A OR 7.0 A, and nothing in between.
