The PI5USB2546A series is USB charging port controller and power switch with an integrated USB 2.0 high-speed data line (D+/D-) switch. PI5USB2546A provides the electrical signatures on D+/D- to support charging scheme 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 and full speed) is fully supported in PI5USB2546A. Additionally, PI5USB2546A 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 multi-port applications.
The PI5USB2546A 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.
