I have a project I am working on, its a shield that plugs into a DUE and is intended to be a LoRa handheld receiver, likely powered by a Lithium battery. I could build in a discrete push button on\off circuit that uses a couple of MOSFETs, with some resistors and capacitors to disconnect the batter…

Pololu electronic power switches They will probably sell you their patented IC.

Thanks for pointing that out, the IC could just be a 8 pin Micro.
