3 Description

The TPS25810A-Q1 device is a USB Type-C

downstream-facing port (DFP) controller with an

integrated 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 is attached, it

applies power to VBUS and communicate 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, it also

applies VCONN power to the cable CC pin. The

TPS25810A-Q1 can identify and report when Type-C

audio or debug accessories are attached.
