Hi everyone,

I have two different voltage suppliers. One from USB and another one from the DC JACK. I want to prevent a situation of short-circuit só I'm implementing this small logic based on the last posts.

From what I have read the logic its ok but imagine if the DC jack is not plugged we have a short-circuit there, right?

Many Thanks,
scuba

 

Typically all you need to do is "diode OR" the multiple power inputs.. Assuming the voltage drop of the diodes is acceptable. I typically use Schottky diodes..

 

Thanks mcgyvr!

Where do you connect the schottky?
