TPS2547 USB Charging Port Controller/Power Switch Texas Instruments TPS2547 USB Charging Port Controller & Power Switch comes with an integrated USB 2.0 high-speed data line (D+/D–) switch. The TPS2547 provides the electrical signatures on D+/D– to support various charging schemes. These devices are tested on popular mobile phones, tablets, and media devices to ensure compatibility with both BC1.2 compliant, and non-BC1.2 compliant devices. The TPS2547 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 supports intelligent port power management in multiport systems.
