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.
