DESCRIPTION  
The TPS2546-Q1 device is a USB-charging port  
controller and power switch with an integrated USB  
2.0 high-speed data-line (D+ and D–) switch. The  
TPS2546-Q1 provides the electrical signatures on D+  
and D– to support charging schemes as described in  
the FEATURES of this data sheet. Texas Instruments  
tests the charging of popular mobile phones, tablets,  
and media devices with the TPS2546-Q1 device to  
ensure compatibility with both BC1.2 compliant and  
non-BC1.2 compliant devices.

In addition to charging popular devices, the TPS2546-  
Q1 device also supports two distinct power-  
management features: power wake and port-power  
management (PPM) through the STATUS pin. Power  
wake allows for power supply control in S4 or S5  
charging and provides PPM with the ability to

Additionally, system wakeup (from S3) with a mouse  
or keyboard (at both low speed and full speed) is fully  
supported by the TPS2546-Q1 device.

The TPS2546-Q1 73-mΩ power-distribution switch is  
intended for applications where heavy capacitive  
loads and short circuits are encountered. Two  
programmable current thresholds provide flexibility for  
setting current limits and load detect thresholds.
