So I built this thing which may or may not be common.
I wanted some feedback on the concept of this schematic. The parts choices , voltages , resistor sizes etc etc were just a quick choice to get the circuit functioning. I fully understand if you were to use this thing a different part number here or there and better biasing is needed. I just wanted to talk about the concept.
Essentially want to take a source that has very little drive capability and at a smaller voltage and give myself the ability to drive several small loads.
When I say small loads, I am simply referring to something like a very low current. Perhaps a pin on a chip that needs to be held high.
Maybe you have hundreds of pins from hundreds of discrete IC's that need to be held high at once. Say these hypothetical pins only draw uA's each but you want to drive 50 of them at once.
So you are doing two things with this.
You are using a 3v drive to create a 5v level shift and giving your self the sourcing current that the p channel mosfet can supply.
Also, I will add, I specifically did not want the inversion.
Just was hoping to get some conceptual thoughts.
Thanks
