The TPS25810A-Q1 device is a USB Type-C downstream-facing port (DFP) controller with anintegrated 3-A rated USB power switch. The device monitors the Type-C configuration channel (CC)lines to determine when a USB device is attached. If an upstream-facing port (UFP) device isattached, it applies power to VBUS and communicate the selectableVBUS current-sourcing capability to the UFP via the pass-through CC line. Ifthe UFP is attached using an electronically marked cable, it also appliesVCONN power to the cable CC pin. The TPS25810A-Q1 can identify and reportwhen Type-C audio or debug accessories are attached.

The TPS25810A-Q1 device draws less than 0.7 µA (typical) from the AUX pin when no USBload is connected. Additional system power saving is achievable in the S4 and S5 system powerstates by using the UFP output to disable the high-power 5-V supply when noUFP 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 inlow-power states (S4 and S5).

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