Is there any way to prevent current from passing through a certain wire without actually cutting off the power from that line.
To be clear, I'm using 2 power source and because of "even with 0.0001v difference, they are going to fry each other when you connected them in parallel" rule, I used Schottky diode but the voltage drop is too much. My power source is 3.3v but with the voltage drop it went to 2.9v. Is there any work around.
Also, will this be a good way for my application https://www.instructables.com/id/Reverse-polarity-protection-for-your-circuit-with/
Based from the circuit alone, I can say that it will cut the power from the source as soon as it sense a reverse current.
I don't wanna protect my device, I just want to combine the 2 power source without frying them. (Wait that's protection) So that's it.
