My rough idea is below. I would like to pull the EN/UVLO pin low when the battery voltage reaches 13.5V. I am unsure if this design would work, I am worried I will always just be reading the output of my switching regulator which is 14.6V. How could I make sure that I am reading the battery voltage and not the switching regulator output, and then compare that battery voltage with a reference so that I can automatically pull the EN/UVLO pin low when Vbattery is 13.5v?
