HI,
For my Project I want my Teensy to be able to switch the power off completely (switched on again by a button press). For this I am using the Enable pin of a buck converter which goes high when the user presses the button and then powers the teensy. As soon as the teensy is started it sets the connected pin to high an the power stays on:
I have used this before with an input voltage of only 4.2v. Now I want to use it with up to 12v and I am wondering if the Teensy will survive the button press (and therefore 12v on its pin). I assume that this is not a good idea. What would be an easy way to protect the Teensy Pin?
Would a series diode in front of the pin help?
The enable pin of the converter requires only 1v or so to be high.
Thakns for your help
