TPS22985 Overview
The TPS22985 is a supply selection device for active Thunderbolt™ cables. The device selects a supply that is at 3.3V from two supply inputs and connects this to two non-current limited outputs OUTA and OUTB. When 3.3V is not present at either supply, the outputs bee high impedance.
