The PIC is running off of a 3.3V supply, while the FET source is tied to a different (totally different rail) 5V. In other words, the 3.3V is from one DC/DC while the source is another totally different DC/DC, not even the same input source. Of course the grounds are all common. BUT.....I have other MIC94053 that I am driving just fine, not on the same supply of course. And nothing else is tied to the PIC pin, just the gate. In order to turn it on and off, I have first set the port output reg bit to 0, then use the TRIS to toggle it. Speed wise, I am inside MPLAB, using a view window and overriding the values by typing in a new value, so its about as slow as it could be. However, I will keep that in mind when I start running full speed (gate charge time) _________________________________________________________________ Get a FREE online computer virus scan from McAfee when you click here. http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
