Figure 8: Timing of Turning on Module
1. Make sure that VBAT is stable before pulling down PWRKEY pin. The time between them is no less
than 30ms.
2. PWRKEY is internally pulled up to an internal voltage in the Qualcomm chipset, and its output voltage
is the internal voltage minus a diode drop in the chipset. Therefore, the expected output voltage of
PWRKEY is 1.5V.
3. PWRKEY should never be pulled down to GND permanently.
3.6.2. Turn off Module
Either of the following methods can be used to turn off the module:
 Normal power down procedure: Turn off the module using the PWRKEY pin.
 Normal power down procedure: Turn off the module using AT+QPOWD command.
3.6.2.1. Turn off Module Using the PWRKEY Pin
Driving the PWRKEY pin to a low level voltage for a duration between 650ms and 1500ms, the module
will execute power-down procedure after the PWRKEY is released.
