Description
The PI5USB2544A/2546A series is a USB charging port
controller and power switch with an integrated USB 2.0 high-
speed data line (D+/D–) switch. PI5USB2544A/2546A
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
PI5USB2544A/2546A. Additionally, PI5USB2546A
supports two distinct power management features, namely,
power wake and port power management (PPM) through
/STATUS pin. Power wake allows for power supply control
in S4/S5 charging and PPM manages port power in a multi-
port application.
The PI5USB2544A/2546A 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
