This application is simply a power switch, so there is no high frequency switching going on. In some reference designs I've seen both a mosFET driver being used, and in other cases a smaller FET used to drive the gate on the power device. So what the better solution, or is there one...ie....either one will work, so becomes more of a cost issue...whats cheaper to manufacture? I know the PIC can't drive it direct, that of course would be the simpilest and cheapest _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
