STUSB4761QTR

STUSB4761QTR is a standalone USB PD controller with integrated CC/CV for AC/DC applications. It integrates a CC/CV regulation loop to drive power regulation stage. The STUSB4761 offers the benefits of full hardware USB PD stack allowing a robust, deterministic and safe negotiation in line with USB PD standard. It is ideal for provider applications in which digital or software intelligence is limited or missing. The STUSB4761 main functions are detecting the connection between two ports (attach detection), establishing a valid source-to-sink connection, determining the attached device mode (sink or accessory), checking cable power capabilities, negotiating a USB PD contract with a PD capable device, configuring the output power path accordingly, regulating voltage and current according to PD contract, monitoring VBUS, managing transitions, handling protections and ensuring user and device safety. Suitable for AC adapters and power supplies, smart plugs and wall adapters applications.
