Hello.
I have a open drain pin (Power Good Pin) thal goes LOW when i have external power, and i have two P mosfets, one for battery and one for external power.
When i have the external power i need to change the mosfets gates, need to put gate of the mosfet linked to External Power to LOW(mosfet is working) and put the gate of Battery mosfet to HIGH(mosfet not working).

When i DON'T have external power i need to invert the gates, must put the External Power Mosfet Gate to HIGH and Battery Gate to Low.

Resuming, when i have external power i need 0-1 on the gates and when i dont have external power i need 1-0 on the gates

Thanks for all help.
