I've got some FETs, in particualar a MIC94053, that I am driving from a PIC by tristating it to turn it off, and drive it low to turn it on. It has a built in PUP, and with 3.3V on the source I am seeing around .8 to .9 V on the drain. I'm going to be doing some experiments and measurements but I am posing the question right now...is this normal to see leakage like this? _________________________________________________________________ Is your PC infected?
