5.6.1. Fast Shut Down by Hardware
The Fast Power Down can be triggered by configuration of any GPIO. HI level to LOW
level transition of GPIO commands fast power down.
Example circuit:
NOTE:
Consider voltage drop under max current conditions when defining
the voltage detector thereshold in order to avoid unwanted shutdown.
The capacitor is rated with the following formula:
TIP:
Make the same plot during system verification to check timings and
voltage levels.
5.6.2. Fast Shut Down by Software
The Fast Power Down can be triggered by AT command.
