Note 7.4 Output leakage is measured with the current pins in high impedance.

Note 7.5 See The USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics Note 7.6 RBIAS is a 3.3V tolerant analog pin.

Note 7.7 Output current range is controlled by program software, software disables FET during short circuit condition.

Note 7.8 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
