I've been using this stepper motor control on a circuit board I've designed. It uses a pic controller to drive it and I've produced quite a few and they've worked pretty well. The chip is fed 12vdc with a 5v voltage reg to run the pic. While it runs I will run my finger on the board to check the temperature of the components to make sure there aren't any issues and apparently this causes the motor control chip to short and overheat. I was looking at the datasheet trying to see if there are pins on this chip that may be sensitive to that. I could see that I could potentially short 12v to the pic but that's not what's burning out. It may need some kind of protection. I would appreciate any help.
