hey guys,
I'm trying to make a circuit to protect against short circuits.... Using this for drone / quad copter building. Alot of people use 12v automotive light bulbs or u can buy simple boards with a ptc resettable fuse circuit...
I'm trying to create a circuit to do the same thing but without using light bulbs to limit current or ptc resettable fuses. I do have a bunch of different size poly fuses but it seems they do not trip fast enough. Can i just use a Schottky Diode? I came across some basic circuit that just use some mosfet to accomplish this but unsure if this is a feasible method. Also I need to be able to use either 12.6v or 14.8. Or both...
Here is one example I found. Put not sure what value of components to use. And how does this circuit protect from reverse polarity ?
if anyone has a better circuit to accomplish this or ideas please let me know. Thanks. Don't want to use relays also.
