I'm a DIY guy, so what I need is some guidance or just schematics for H bridges. I'd like to use only N channel mosfets, so the drivers should take care of it. The controller will have their own PIC to actuate the mosfet gates under command of the main PIC for speed and direction. > I need just some sample circuits, so I can compare with my own design and maybe grab some ideas. > Any help? > > Thank you very much. > > Marcelo Fornaso > from Buenos Aires - Argentina > If your goal is to get your homemade segmay moving in the next year you should copy the OSMC (open source motor controller) design or buy a board/kit from companies who sell them. There are a lot of details that go into designing a motor controller that doesn't burst into flames, yet works well. -- Martin K. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
