The TPS2547 is a USB charging port controller and power switch with an integrated USB 2.0
high-speed data line (D+/D–) switch. TPS2547 provides the electrical signatures on D+/D– to support
charging schemes listed in Feature Description section. TI tests
charging of popular mobile phones, tablets, and media devices with the TPS2547 to ensure
compatibility with both BC1.2 compliant, and non-BC1.2 compliant devices.
In addition to charging popular 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. Additionally, system wake up
(from S3) with a mouse/keyboard (both low speed and full speed) is fully supported in the
The TPS2547 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.
