DESCRIPTION
The TPS2543-Q1 is a USB charging port controller
and power switch with an integrated USB 2.0 high-
speed data line (D+/D–) switch. TPS2543-Q1
provides the electrical signatures on D+/D– lines to
support charging schemes listed under device feature
section. TI tests charging of popular mobile phones,
tablets and media devices with the TPS2543-Q1 to
ensure compatibility with both BC1.2 compliant and
non-BC1.2 compliant devices
In addition to charging popular devices, the TPS2543-
Q1 also supports two distinct power management
features, namely, power wake and port power
management (PPM) via the STATUS pin. Power
wake allows for power supply control in S4/S5
charging and PPM the ability to manage port power in
a multi-port applications. Additionally, system wake
up (from S3) with a mouse/keyboard (low speed only)
is also supported in the TPS2543-Q1
The TPS2543-Q1 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.
