Input threshold of HX2 BUSPOWER pin

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

 

Answer:

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.
