I just got done with a 1500 mile drive with my 1 year old in the back seat from Olympia to Maricopa. Boy that wasn't fun! We even ran over the big fat middle section of a dead deer. Rain and 60 in Washington, sun and 105 down here. haha.
You can definitely get multiple gate drivers to work. Ian Hooper (who is the reason I started working on controllers for cars in the first place) has made reliable controllers using up to 6 drivers and 12 mosfets. He didn't tie the outputs (pwm) of the drivers together though. He just had 2 mosfets per driver on a separate little driver board. Maybe the blowup was caused by something else? Those drivers have like a 15nS response time. Do you know at approximately what conditions (current of motor, current from batteries, pwm duty) the controller blew up?
mora, I'll try to find the .hex file. Man, I'm awful with knowing which version is which, and not keeping old versions. I tried SVN once, and wanted to stab myself in the eyeball with a fork afterwards.
