Description

The PI5USB2546AQ series is a USB charging port controller and power switch with an integrated USB 2.0 high-speed data line (D+/D-) switch. PI5USB2546AQ provides the electrical signatures on D+/D- to support charging schemes listed under device feature section. The 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 PI5USB2546AQ . Additionally, PI5USB2546AQ supports two distnct power management features, namely, power wake and port power management (PPM) through /STATUS pin. Power wake allows for power supply control is S4/S5 charging and PPM manages port power in a multi-port application. 

The PI5USB2546AQ 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.
