Description
The PI5USB2544 is a USB charging port controller and
power switch with an integrated USB 2.0 high-speed data
line (D+/D–) switch. PI5USB2544 provides the electrical
signatures on D+/D– to support charging schemes listed
under device feature section. This series is compatible with
both popular BC1.2 compliant and non-BC1.2 compliant
devices.
System wake up (from S3) with a mouse/keyboard (both low
speed and full speed) is fully supported in the PI5USB2544.
The PI5USB2544 series 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.
Applications
 USB Ports (Host and Hubs)
 Notebook and Desktop PCs
 Universal Wall Charging Adapters
