When the module is in power off mode, driving PWRKEY low for 500–1000 ms and then releasing it will
turn on the module. It is recommended to use an open drain/collector driver to control PWRKEY.
A simple reference design is illustrated in the following figure.
Another way to control PWRKEY is with a button. Pressing the button may result in a discharge of static
electricity from a finger. Therefore, it is vital to place a TVS component near the button for ESD protection.
