For low-voltage inputs (less than 5 V), there are load switches available with a single integrated MOSFET but have the ability to block reverse current when disabled. These switches can accomplish this by effectively removing the body diode of the integrated FET while the switch is disabled.
If using one of these load switches with an active high enable and another load switch with active low enable, you can select between each power path while using only 1x GPIO.
For higher input voltages (> 5 V), there are eFuse switches available with back-back MOSFETs. They can be used in a priority mux configuration (see Figure 3-4).
To learn more about how to use load switches or eFuses in a MUX configuration, see Power Multiplexing Using Load Switches and eFuses.
