Note 9-3

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

Note 9-4

See the USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics

Note 9-5

RBIAS is a 3.3 V tolerant analog pin.

Note 9-6

Output current range is controlled by program software. The software disables the FET during short

circuit condition.
