NOTES
1. Make sure that VBAT is stable before pulling down PWRKEY pin, and keep the interval no less than
30ms.
2. PWRKEY 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. Therefore, the expected output voltage of
PWRKEY is 0.8V.
