ME910G1 HW Design Guide

NOTE:
Do not use any pull up resistor on the HW_SHUTDOWN* line nor any
totem pole digital output. Using pull up resistor may bring to latch up
problems on the ME910G1 power regulator and improper functioning
of the module.
To proper power on again the module please refer to the related
paragraph (“Power ON”)
The unconditional hardware shutdown must always be implemented
on the boards and should be used only as an emergency exit
procedure.
Fast power down
The procedure to power off ME910G1 described in Chapter 5.3 normally takes more than
1 second to detach from network and make ME910G1 internal filesystem properly closed.
In case of unwanted supply voltage loss the system can be switched off without any risk of
filesystem data corruption by implementing Fast Shut Down feature.
Fast Shut Down feature permits to reduce the current consumption and the time-to-
poweroff to minimum values.
NOTE:
Refer to ME910G1 series AT command reference guide (Fast power
down - #FASTSHDN) in order to set up detailed AT command.
