Thanks for the info, however I don't really like the idea of only using half the in/outputs of the H bridge, cause lets say I'd want to make multiple PCBs, or that I need small PCB's, then there really is a cost to having such an H-birdge. I'm sort of surprised that the kind of H bridge I need seems hard to find because it seems fairly standard. Or are H-bridges only used by hobbyists? Do all commercial products implement their own H-bridge? And if so, why? Doesn't this take up more space than a small simple 8pin H bridge? It also seems more error prone.
