Note
1: Use a single point ground for the ground lines if at all possible.
2: Here, a 1 resistor is attached for each of the SEN pin resistors. This sets an output of 200 mA when the current ratio is 100%.
3: The LIM7 reference voltage can be provided either as an external voltage or by using VREF7: either voltage dividing VREF7 (0.2 V) or simply
shorting LIM7 to VREF7.
