I need a design a circuit that includes NTC as an interrupt source for MCU.
When it gets warm, the MCU pin needs to receive 3.3V.
I have to power sources for the circuit, and can use one of them - 3.3v and 5v.
the MCU pin can only sink up to 4mA.
Any ideas?
Thanks!

I havent picked a right NTC yet, i'd like it to be around 10Kohm, but its not a must.
