Post by thread:[PICLIST] [EE}:FET switch

A while ago someone posted a circuit of a FET switch to switch a voltage higher than +5 volts with a 5 volt level. Can someone direct me to that post. TIA, Peter -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

Do you mean a high side switch? What kind of current? I use a P channel FET for the high side, the gate driven by an N channel FET, who's gate is driven by a 5 volt level. Add 2 resistors as a voltage divider on the P channel FET and your done.
