LSF0108: LSF0108 application question

Part Number: LSF0108

Hi team,

Here are a few questions would like to ask,
1. Regarding the bias resistor, the current datasheet indicates the use of 200kohm, but I found that the yellow position in the picture below is 3.3V, but the green position will drop to 2.1V.
Is this voltage drop in line with your expectations? Will this affect the required voltage of Vref_B and EN pin and cause performance changes?
2. At present, if the B side is 3.3V and the A side line is not connected to the signal (floating)
a. Our A-side external supply voltage will be pulled up entirely, from 1.2V to 1.6V.
b. Even if side A is not connected to an external power supply, there will still be 2.5V power.
Does this meet your expectations?

Thanks!

Best,

Alice
