Use the following instructions to perform Simple ORing test:

1. Use Channel 1 and Channel 2 to test ORing capability of LM73100.
2. Populate R24 with 0Ω resistor to connect VOUT1 and VOUT2.
3. Change the UVLO threshold setting for each channel as per the voltage intended to be applied.
4. Apply voltage on Channel 1 and Channel 2. Different voltages can be applied on Channel 1 and Channel 2.

5. Test various conditions

   1. Ramp up voltage on the low voltage rail to a value greater than the other rail to see output always follow the highest voltage rail

   2. Ramp down voltage on the highest voltage rail to a value lower than the other rail to see output always follow the highest voltage rail

Figure 5-3 shows an example of simple ORing on the LM73100EVM Ideal Diode Evaluation Board.
