TPS2413: TPS2413 unexpected voltage

TPS2413: Gate voltage observations

I'm using TPS2413 for Oring the two power supplies and my input voltage to ORing controllers was 12 V and I'm getting gate voltage of 23V. Is this Behavior is expected??

    Hi Bhargava,

    The GATE voltage with respect to the A pin will be around 10,.5V. If the input voltage or the A pin voltage is 12V then the GATE-GND voltage measured will be 12V + 10.5V = 22.5V. This is an expected behavior.
