Hello,
I am losing my time on a field, that I do not know – MOSFET. Namely, in a design, I have two possible sources of voltage – it can be active any of them or both with max 150mA. Till now I was on 5V and to have two diodes BAT754 it was not so big drop in percentage.
Now I switched to 3,3V and every mV counts. On net I saw design with MOSFET as a low drop diode. Since I need two, I tried with IRF7754 with around 34mOhm ON resistance. Result? If I apply voltage on any of inputs, there is a short.
Do any have any idea where I made mistake or how to solve this other way? Tnx.
Best regards,
Andrej
