USB Charging Port Controller and Load Detection Power Switch

Features

Description

 Supports DCP Modes per USB Battery Charging

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.

Specification 1.2

 Supports Shorted Mode per Chinese Telecommunication

Industry Standard YD/T1591-2009

 Supports non-BC1.2 Charging Modes by Automatic

Selection

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.

 Divider-1A mode

 Divider-2A mode

 Divider-2.4A mode (with MODE_SEL=’HIGH’ only)

 DCP-1.2V mode

 Integrated 65-mΩ (Typ.) High-Side MOSFET

 Programmable Current Limit up to 3A (Typ.)

 Accurate +/-7% Current Limit at 2.51A (Typ.)
