5 Description (Continued)

The TPS25810A-Q1 device draws less than 0.7 µA (typical) from the AUX pin when no USB load is connected. Additional system power saving is achievable in the S4 and S5 system power states by using the UFP output to disable the high-power 5-V supply when no UFP is attached. In this mode, the device is capable of running from an auxiliary supply (AUX), which can be a lower-voltage supply (3.3 V), typically powering the system microcontroller in low-power states (S4 and S5).

The TPS25810A-Q1 device integrates a 34-mΩ power switch with a fixed 3.4-A current limit independent of the Type-C current advertisement level. The FAULT output signals when the switch is in an overcurrent or overtemperature condition. The CS output is used for implementing digital cable compensation for load currents greater than 1.95 A. Cable compensation, also known as line drop compensation, is a means of offsetting voltage droop from the USB power supply to the UFP load.
