I have a project that runs off a 4S LIPO battery and I want to switch to 24V wall power when I plug in an DC wall adapter. I have two designs, an inexpensive one with discretes and one with an expensive LTC4412HV IC.
I simulated both and they seem to work fine. In terms of safety since the battery is a LIPO, is the discrete design okay? Is there anything I should add other than a fuse which I already have?
Edit: The reason I use a PFET instead of a schottky diode is because the diode consumes too much power and I want to maximize battery life.
