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

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

RBIAS is a 3.3 V tolerant analog pin.

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

condition.

Supply currents do not include power FET currents.

HS Host, 2 ports active.

11:

Noise on the RESET_N signal can affect the startup, a clean 100us rise time is recommended for consistent

startup.
