3 Description
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 V_BUS and communicates 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, the
TPS25810‑Q1 device also applies V_CONN 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).
(1) CC pins are IEC-61000-4-2 rated
