3 Description
The TPS25810 is a USB Type-C Downstream Facing
Port (DFP) controller with an integrated 3-A rated
USB power switch. The TPS25810 monitors the
Type-C
Configuration
Channel
(CC)
lines
to
determine when an USB device is attached. If an
Upstream Facing Port (UFP) device is attached, the
TPS25810 applies power to VBUS and communicates
the selectable VBUS current sourcing capability to the
UFP via the passthrough CC line. If the UFP is
attached using an electronically marked cable, the
TPS25810 also applies VCONN power to the cable CC
pin. The TPS25810 also identifies when Type-C
audio or debug accessories are attached.
The TPS25810 draws less than 0.7 uA (typ) when no
device is attached. Additional system power saving is
achievable in S4/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 uC in low power states (S4/S5).
The
TPS25810
34-m
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 over current or over temperature
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).
