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. Customers should expect to see ~0.8V on the PWRKEY pin, because of there is pulled up to an

internal voltage minus a diode drop in the Qualcomm chipset.

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+QPOWDcommand.

3.6.2.1. Turn off Module Using the PWRKEY Pin

Driving the PWRKEY pin to a low level voltagefor at least 650ms, the module will execute power-down

procedure after the PWRKEY is released.

The power-down scenario is illustrated inthe following figure.
