Hello and thanks always.
I have used BJT transistors mainly. I dont understand JFETs or MOSFETS so I would appreciate someone explain this to me.
In particular the following case:
You see the part that is surrounded by a red circle??
1) Is that a MOSFET? or a JFET? or what... There are so many symbols for these kind of transistors (some with a circle, some without a circle) that I dont understand. Is that N-channel? or P-channel??
2) I understand the purpose of the above circuit. What it wants to do is that when applying a "SLEEP" signal VDD is going to go to Ref (so as to activate the SLA7080x sleep mode but forget about that) and when no SLEEP signal all we are gonna have is a normal voltage divider... But isnt it inverted???
I mean the current must go from 5V to Ref right? why the arrow on the other direction then???
3) There is no suggestion at to what transistor to use here... Any examples of JFETs (or is it MOSFETs? ..confused) that I can take a look?
Thanks a lot in advance
