When BG96 is in power off mode, it can be turned on to normal mode by driving the PWRKEY pin to a low
level for at least 100ms. It is recommended to use an open drain/collector driver to control the PWRKEY.
After STATUS pin outputting a high 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.
