PICs, if you can wait for their ground shipping (3-10 days)). Spent hours trying to get them to work. Either they would do nothing, or the chip would go into some kind of "controlled latchup"; it would start gobbling up about 0.5A, and start getting warm, but _still_ do nothing. No responses to control inputs, nothing on the scope or FETs at the outputs. Maybe I got 3 duds, or I was making some dumb mistake; YMMV. I found the National LMD18xxx integrated H-bridges to be good if you are prototyping and your max continuous current is <3A, max pulsed <6A. What about the FET drivers Microchip makes? Yeah, they're not 1-piece like the HIP408x, but have people tried them? Experiences? Cheers, Ishaan -- http://www.piclist.com#nomail Going offline?
