4.2. Turn-on
The turn-on method of BG95 is the same as that of BG96. BG95 can be powered on through pressing
PWRKEY for 500ms to 1000ms, and BG96 can be powered on through pressing PWRKEY for at least
500ms.
The PWRKEY pin of BG95/BG96 is internally pulled up to an internal voltage in the Qualcomm chipset,
and its output voltage is the internal voltage minus a diode drop in the chipset. For BG95, the expected
output voltage of PWRKEY is 1.5V. For BG96, the expected output voltage of PWRKEY is 0.8V.
The following is a reference design for the turn-on circuit of BG95 and BG96.
