I need an application with back-up battery. Like UPS when power go down device will work with battery. There are chips with power path option but it is diffucult me to get components from outisde of my country (not impossible but diffucult and expensive so i stick components can be found here) and the one i got bq24072 it is very diffuclt to solder. So i came up with below idea with mcp73831 but i am not sure it will work. I will try it with dead-bug prototyping after i get opinions (i am afraid of blowing battery on my face). I am planning to use Li-Po battery
MOSFET's gates can be driven with transistors. The battery symbol is only for showing where the battery is. Will that work or can anyone suggest better solution. or i shoul stick with a chip which has power-path feature?
