Input threshold of HX2 BUSPOWER pin

Version 1
    Question: What is the input threshold of the HX2 BUSPOWER pin?



    The input threshold of BUSPOWER pin is about 1.5 V, so when connected to VBUS or any input exceeding the threshold will result in driving the pull up on D+, signalling a connect event. When BUSPOWER pin is connected to 3.3 V, it should work as well.
