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

D+/D– CDP/DCP Modes per USB Battery  
Charging Specification 1.2  
D+/D– Shorted Mode per Chinese  
Telecommunication Industry Standard YD/T  
1591-2009  
•
Supports non-BC1.2 Charging Modes by  
Automatic Selection  
–
D+/D– Divider Modes 2.0V/2.7V and 2.7/2.0V  
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

Supports Sleep-Mode Charging and Low  
Speed Mouse/Keyboard Wake Up  
Load Detection for Power Supply Control in  
S4/S5 Charging and Port Power Management  
in all Charge Modes

•
•
Integrated 73-mΩ (typ) High-Side MOSFET  
Adjustable Current-Limit up to 3 A (typ)  
Operating Range: 4.5 V to 5.5 V  
Max Device Current  
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.
