I am building a power switching circuit that has three inputs and should connect them in a predefined order.
I found the dedicated LTC4417f IC which does just that but I would like to have adjustable voltage threshold resistors and other functions/monitoring.
Would a Arduino be fast enough in reading voltages and switching mosfets in order to no have power drops? A capacitor could also solve the problem but since the supplied device needs constant 5A (max 10A) power I would like to make sure that I am doing the right thing.
Is the speed question relevant? What would be a good mosfet choice?
Any pointers will help in finding the way through the thousands of schematics and parts.
