Description

The PI5USB2546J is a USB charging port controller and power switch with an integrated USB 2.0 high-speed data line (D+/D–) switch. The PI5USB2546J 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. The PI5USB2546J fully supports system wake up (from S3) with a mouse/keyboard (both low speed and full speed). The
PI5USB2546J also 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 PI5USB2546J 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.
