Note 7.5 Output leakage is measured with the current pins in high impedance.

Note 7.6 See The USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics

Note 7.7 RBIAS is a 3.3V tolerant analog pin.

 

 

 

 

Note 7.8 Output current range is controlled by program software, software disables FET during short

circuit condition.
