Battery generally used in case power off. they have lots of time in between (Turn OFF to ON or vice versa). Now u should make sure about the current paths in all cases. Use Back-Back MOSFETs in each leg. Linear technology is master in this. U can use LT4416,LT4412,LT4417 etc. TPS2110,2111 etc. Check this link powerelectronics.com/discrete-power-semis/… | |

| Apr 1, 2016 at 6:56 | comment | added | Raheel Bari | Yes, application required low drop out. Yes, control cct is there but even if turn off of mosfet is larger then on time then current from upper mosfet of adapter might still flow to lower mosfet of battery. | |

| Apr 1, 2016 at 6:23 | comment | added | kingchris | Why Mosfets. They are not fully off with no input control so current can flow with dangerous results in your application. Yes they can operate like low voltage drop diodes but your control needs to be very precise. | |
