SMSC USB2250/50i/51/51i 31 Revision 1.1 (05-29-08)
DATASHEET
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.
