Note 9-5
Output leakage is measured with the current pins in high impedance.
Note 9-6
See The USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics
Note 9-7
RBIAS is a 3.3 V tolerant analog pin.
Note 9-8
Output current range is controlled by program software, software disables FET during short circuit
condition.

Package Thermal Specification
Note 9-9
Thermal parameters are measured or estimated for devices with the exposed pad soldered to thermal
vias in a multilayer 2S2P PCB per JESD51. Thermal resistance is measured from the die to the
ambient air.
