The MAX44285 datasheet specifies that the full-scale input voltage across the sense resistor (VSENSE) is 125mV for T version (The MAX44285T has gain of 20V/V). In order to sense 30A current, the sense resistor need to be less than 125mV/30A=4mΩ. So, users need to reduce the Rsense values on each channel to 4mΩ or below (Red circles in the figure below).
Note that all the current values in the software GUI are calculated with 5mΩ sense resistor. Users need to re-scale these calculations with the new Rsense value.
