ok..different thread, same design..... I designed in this great part from Vishay, the Si4788CY. 5A capability, SO8 package AND you can drive it direct with 1.8 to 5V logic levels, no matter what the voltage is you are switching. BUT.....can't seem to be able to buy them now. So i need a substitute, driving with a PIC16LF877 directly, switching 1.8V,3.3V and 5V with this part. Anyone have a favorite? _________________________________________________________________ Learn how to choose, serve, and enjoy wine at Wine @ MSN. http://wine.msn.com/ -- http://www.piclist.com hint: The PICList is archived three different ways.
