I'm sure I've read the answer somewhere before, but the search button isn't being too helpful right now. Can I run a +12V line via a 100K resistor into an AVR (AtTiny261)?
Basically, I've had to jerry rig up a MOSFET controlled power on/off switch controlled by the AVR. I'm using an FDS6675 P-Channel MOSFET, to switch +12V to a load. There is a 100K pullup on the gate, and I'm hoping I can just run the gate into the AVR direct. Normally I run via a second N-Channel MOSFET, but I'm hoping due to the jerry rig problem that I can get away without it.
The tiny261 datasheet says max is VCC + 0.5 which makes sense, but it doesn't mention current. The 100K should limit the current to 0.1mA, so would that be acceptable?
