3 Description
The TPS2546-Q1 is a USB charging port controller
and power switch with an integrated USB 2.0 high-
speed data line (D+/D–) switch. TPS2546-Q1
provides the electrical signatures on D+/D– to support
charging schemes listed under Feature Description.
TI tests charging of popular mobile phones, tablets,
and media devices with the TPS2546 to ensure
compatibility with both BC1.2 compliant, and non-
BC1.2 compliant devices.
In addition to charging popular devices, the TPS2546-
Q1 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 the ability to manage port power in
a multi-port application. Additionally, system wake up
(from S3) with a mouse/keyboard (both low speed
and full speed) is fully supported in the TPS2546-Q1.
The TPS2546-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.
