The TPS2544 is a USB charging port controller and power switch with an integrated USB 2.0 high-speed data line (D+/D–) switch. TPS2544 provides the electrical signatures on D+/D– to support charging schemes listed under device feature section. TI tests charging of popular mobile phones, tablets and media devices with the TPS2544 to ensure compatibility with both BC1.2 compliant and non-compliant devices. In addition to charging popular devices, TPS2544 also supports system wake up (from S3) with a mouse/keyboard; both low speed and full speed are supported.

The TPS2544 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.
