3 Description

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 TPS2547.

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.
