TPS25944A: Priority power muxing

Hi. Experts.

I need a Power Mux circuit for a new project I'm working on.

The primary power source is a 48V constant power supply, and the secondary power source is a 3.7V battery.

I need a power circuit where the battery serves as a backup power source when the primary 48V power supply fails due to a power outage.

The system's power consumption is approximately 3A.

Please recommend a suitable Power Mux system and components for this scenario.

Thanks.
