3.6.1. Turn on Module Using the PWRKEY Pin

The following table shows the pin definition of PWRKEY.

PWRKEY 15
When BG96 is in power off mode, it can be turned on by driving the PWRKEY pin to a low level for at least
500ms. It is recommended to use an open drain/collector driver to control the PWRKEY. After STATUS pin
outputs a high voltage level, PWRKEY pin can be released. A simple reference circuit is illustrated in the
following figure.

Another way to control the PWRKEY is using a button directly. When pressing the key, electrostatic strike
may generate from the finger. Therefore, a TVS component is indispensable to be placed nearby the
button for ESD protection. A reference circuit is shown in the following figure.
