I would also be interested in plans for such an H-Bridge. I have two 12Vdc motors than take 3.5 Amps at full load (actually gearhead motors so I get lots of torque @50 RPM) but they have surges us to 12 - 14 Amps at start-up and if they get stalled. (...)

Sure, I've built several. The only "trick" to MOSFET bridges is that if you use all N-channel FETs you need a charge pump on the upper FETS. (look out for typos, this was done 'off the cuff' so to speak.) Chuck's Simple MOSFET Tutorial ---...--- (...) (28 years ago, 20-Jan-97, to lugnet.robotics.handyboard)

Hello, does anyone know how to build a mosfet hbrige and, if so, could they pass that on to me? It is my understanding that the mosfet hbridge does not heat up near as much as the transistor hbridge nor does it have any loss of voltage or current (...)
