I have an IC that is activated when pulsing a pin high, the pin should be keep floating after the pulse. The circuit is powered using a battery, and that IC then wake up everything else (Regulator, MCU, etc).
I'm looking for something like this:
Battery -> Pulse to the pin -> IC wakes up -> IC wakes up everything else
I'm trying to guess how to do that in simple terms, I mean without adding even more complexity to the circuit.
I have tried bridging the pin to the + of the battery manually for a moment (< 1 sec) and it works, but only after removing the + from the pin.
So the question is: How do I create a brief pulse using simple components? It is possible?
