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 V_BUS and communicate the
selectable V_BUS 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 V_CONN power to the cable CC pin. The
TPS25810A-Q1 can identify and report when Type-C
audio or debug accessories are attached.
