The TPS25810 is a USB Type-C Downstream Facing Port (DFP) controller with an integrated3-A rated USB power switch. The TPS25810 monitors the Type-C Configuration Channel (CC) lines todetermine when an USB device is attached. If an Upstream Facing Port (UFP) device is attached, theTPS25810 applies power to VBUS and communicates the selectableVBUS current sourcing capability to the UFP via the passthrough CC line. Ifthe UFP is attached using an electronically marked cable, the TPS25810 also appliesVCONN power to the cable CC pin. The TPS25810 also identifies when Type-Caudio or debug accessories are attached.

The TPS25810 draws less than 0.7 uA (typ) when no device is attached. Additional systempower saving is achievable in S4/S5 system power states by using the LD_DET output controls powermanagement to multiple high current Type-C ports in an environment where all ports cannotsimultaneously provide high current (3 A).
