DESCRIPTION
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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
