The following table shows the pin definition of PWRKEY.
Table 7: Pin Definition of PWRKEY
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.
