Description

The PI5USB2546Q is a USB charging port controller and

power switch with an integrated USB 2.0 high-speed data

line (D+/D–) switch. PI5USB2546QQ 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 PI5USB2546Q.

Additionally, PI5USB2546Q 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 PI5USB2546Q 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

Automotive

USB Ports (Host and Hubs)

Notebook and Desktop PCs

Universal Wall Charging Adapters
