3 Description
The TPS2547 is a USB charging port controller and
power switch with an integrated USB 2.0 high-speed
data line (D+/D–) switch. TPS2547 provides the
electrical signatures on D+/D– to support charging
schemes listed in Feature Description section. TI
tests charging of popular mobile phones, tablets, and
media
devices
with
the
TPS2547
to
ensure
compatibility with both BC1.2 compliant, and non-
BC1.2 compliant devices.
In addition to charging popular devices, the TPS2547
also
supports
two
distinct
power
management
features, namely, power wake and port power
management (PPM) through the STATUS pin. Power
wake allows for power supply control in S4/S5
charging and PPM supports intelligent port power
management
in
multiport
systems.
Additionally,
system wake up (from S3) with a mouse/keyboard
(both low speed and full speed) is fully supported in
the TPS2547.
The TPS2547 73-mΩ power-distribution switch is
intended for applications where heavy capacitive
loads and short-circuits are likely to be encountered.
Two
programmable
current
thresholds
provide
flexibility for setting current limits and load detect
thresholds.
