Description
The PI5USB2549 is a USB charging port controller and
current limiting power switch. PI5USB2549 provides the
electrical signatures on D+/D– to support different charging
schemes and is compatible with both popular BC1.2
compliant and non-BC1.2 compliant devices.
The PI5USB2549 65-mΩ power-distribution switch is
intended for applications where heavy capacitive loads and
short-circuits are likely to be encountered. Programmable
current threshold provides flexibility for setting current limit.
PI5USB2549 provides a /STATUS pin for plug-in detect
indication.
