Hello everyone!

I am building this little to power my electronic work tools from Battery and Power Supply.
Power Supply 12V
Batteries 14V LiIon



The idea is to have a hard priority on V1 (power supply) when it's plugged, and when unplugged it switches to battery (V2, 14V). This little IC was needed because of the higher voltage on the battery.

Also it's great because of the low loss of PFET vs Schottky diodes.

So far, it works great on breadboard, so I'm ready to make it a PCB.

1. Does my schematic makes sense? (FIG2)
2. Do I need additional diodes at outputs before polyfuses to protect the outputs furthermore, or the circuit is already protected enough by the PFET -- I really want to avoid additional voltage drop, and also want to avoid additional circuitry for an ideal diode. (FIG3)
3. Any recommendations? Advices? Complaints??

 

I noted the TVS diode are wrongly connected. Edited schematic
