PI5USB2546 USB Charging Port Controller and Load Detection Power Switch Features Description Supports CDP/DCP Modes per USB Battery Charging The PI5USB2546 is a USB charging port controller and Specification 1.2 power switch with an integrated USB 2.0 high-speed data Supports Shorted Mode per Chinese Telecommunication line (D+/D) switch. PI5USB2546 provides the electrical Industry Standard YD/T1591-2009 signatures on D+/D to support charging schemes listed Supports non-BC1.2 Charging Modes by Automatic under device feature section. This series is compatible with Selection both popular BC1.2 compliant and non-BC1.2 compliant Divider-1A mode devices. Divider-2A mode System wake up (from S3) with a mouse/keyboard (both low DCP-1.2V mode speed and full speed) is fully supported in the PI5USB2546. Supports Sleep-Mode Charging and Mouse/Keyboard Additionally, PI5USB2546 supports two distinct power Wake up management features, namely, power wake and port power Automatic SDP/CDP Switching for Devices that do not management (PPM) through /STATUS pin. Power wake request for the CDP Ports allows for power supply control in S4/S5 charging and PPM Load Detection for Power Supply Control in S4/S5 Charging and Port Power Management in all Charge manages port power in a multi-port application. Modes The PI5USB2546 73-m power-distribution switch is Compatible with USB 2.0/3.0 Power Switch requirements intended for applications where heavy capacitive loads and Integrated 73-m (Typ.) High-Side MOSFET short-circuits are likely to be encountered. Two Adjustable Current-Limit up to 3A(Typ.) programmable current thresholds provide flexibility for Operating Range:4.5V to 5.5V setting current limits and load detect thresholds.
