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.

Note 7.9

The assignment of each Integrated Card Power FET to a designated Card Connector is

controlled by both firmware and the specific board implementation. Firmware will default to

I/O12, I/O12PU & I/O12PD Type
