Part Number: TPS2413
I used the ORing Power Rail Controller (TPS2413) in 12V input ,the sch as follows,
When only 12V_1 is on ,The other power will have 2.5V Voltage ,which will drive the LED on .In
http://e2e.ti.com/support/power_management/power_interface/f/204/t/537301 , It’s said that it have leakage current from C to A of up to 10uA. A small load on the front end of ~ 5.11k should be enough to bring to acceptable.
I tried 4.7K, the voltage drop to 2.2V,when I changed to 150K .A changed to -0.5V. I want to konw if my design changed to 150k ,will there any risks in my power-supply system?

any new developments?
In reply to user5215821:
I have check on the EVM.
With 5K at A, I measure 4.6V, --> this means 0.92mA current.
With 150k at A, I measure 10.0V --> this means 0.066mA current.
This is consistent with attached measurement from the E2E thread
Attached the results here again for reference.

By any chance do yo have additional resistance path on A, coming in parallel?
