This is a major issue I've been having lately. I am designing H-Bridges for stepper motors. And at low amperage, 2A -5A, matching resistance of the NPN and PNP Mosfets is easy, having a perfectly balance bridge. But when you get into the 10A range, that is where the matching ends. What I find is that almost always the PNP has a higher resistance than the NPN.
I know there are ICs that are complete H-bridges, but I haven't found any that can handle 10A or more. So, I am going to stick with building the bridge from individual Mosfet.
With that being said, where can I find impedance matched NPN and PNP pairs that can handle 10A or more? Any help would be greatly appreciated.
