Gates 1.8V to 5.5V power to a system to get extremely low standby power, with a timer to enable power periodically, as well as a button push to activate the system as needed.
* CR2032 battery holder and off-board power supply/battery connector.
* On-board and off-board On button support.
* Use either a 0603 or 1/8W resistor to set the length of time the system is off
* Use DONE signal to remove power programmatically
Datasheet shows how to select resistor value to set timer period.
Q1 can be DMG2305UX or other low-on resistance SOT23-3 PFET
