Due to the general confusion and chaos that seems to reign supreme in my life, I managed to order AH173 Hall-Effect sensors from Mouser when I had been using AH175's. The difference being the AH173 has an internal pullup resistor.
I'm not understanding how that works tho. I thought a pull up was selected based on Vcc and the desired operating current. How can the 173 have the right pullup for the entire Vcc range?
I'm gonna hook one up and see what happens when they get here, lol, but I'd like to know what I'm missing on this ....
Thanx for any and all education on the subject.
