Current sense select test

Current sense resistor value selection

This resistor value will determine the voltage outputted to the gpio, therefore we want to limit the maximum voltage output to 3.3V or whatever the gpio is rated for. 

1.2A loadswitch IS resistors (ratio constant on datasheet = 670) (ratio by expirement = 683.33)
-1708.325 for expiremented constant @ 1.2A
-1675 for datasheet constant @ 1.2A
-1600 choosen for 1.256A @ 3V for datasheet, and 1.281A @ 3V for expiremental

4.5A loadswitch IS resistors (ratio constant on datasheet = 1800)
-1200 for datasheet constant @ 4.5A
-1210 choosen 4.463A @ 3V
