The TPS25810-Q1 device is a USB Type-C downstream-facing port (DFP) controller with an integrated 3-A rated USB power switch. The TPS25810-Q1 device monitors the Type-C configuration channel (CC) lines to determine when a USB device is attached. If an upstream-facing port (UFP) device is attached, the TPS25810-Q1 device applies power to VBUS and communicates the selectable VBUS current-sourcing capability to the UFP via the pass-through CC line. If the UFP is attached using an electronically marked cable, the TPS25810‑Q1 device also applies VCONN power to the cable CC pin. The TPS25810-Q1 device also identifies when Type-C audio or debug accessories are attached.

The TPS25810-Q1 device draws less than 0.7 µA (typ) when no device is attached. 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 µC in low-power states (S4 and S5).

The TPS25810-Q1 34-mΩ power switch has two selectable fixed-current limits that align with the Type‑C current levels. The FAULT output signals when the switch is in an overcurrent or overtemperature condition. The LD_DET output controls power management to multiple high-current Type-C ports in an environment where all ports cannot simultaneously provide high current (3 A).
