PI5USB2546Q USB Charging Port Controller and Load Detection Power Switch Features Description AEC-Q100 Qualified The PI5USB2546Q is a USB charging port controller and Supports CDP/DCP Modes per USB Battery Charging power switch with an integrated USB 2.0 high-speed data Specification 1.2 line (D+/D) switch. PI5USB2546QQ provides the electrical Supports Shorted Mode per Chinese Telecommunication signatures on D+/D to support charging schemes listed Industry Standard YD/T1591-2009 under device feature section. This series is compatible with Supports non-BC1.2 Charging Modes by Automatic both popular BC1.2 compliant and non-BC1.2 compliant Selection devices. Divider-1A mode System wake up (from S3) with a mouse/keyboard (both low Divider-2A mode speed and full speed) is fully supported in the PI5USB2546Q. DCP-1.2V mode Additionally, PI5USB2546Q supports two distinct power Supports Sleep-Mode Charging and Mouse/Keyboard management features, namely, power wake and port power Wake up management (PPM) through /STATUS pin. Power wake Automatic SDP/CDP Switching for Devices that do not allows for power supply control in S4/S5 charging and PPM request for the CDP Ports manages port power in a multi-port application. Load Detection for Power Supply Control in S4/S5 Charging and Port Power Management in all Charge The PI5USB2546Q 73-m power-distribution switch is Modes intended for applications where heavy capacitive loads and Compatible with USB 2.0/3.0 Power Switch requirements short-circuits are likely to be encountered. Two Integrated 73-m (Typ.) High-Side MOSFET programmable current thresholds provide flexibility for Adjustable Current-Limit up to 3A(Typ.) setting current limits and load detect thresholds.
