3 Description

The TPS2543 is a USB charging port controller and power switch with an integrated USB 2.0 high-speed data line (D+/D–) switch. TPS2543 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 to ensure compatibility with both BC1.2 compliant and non-BC1.2 compliant devices.

In addition to charging popular devices, the TPS2543 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.

The TPS2543 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.
