Implement a full-feature USB Type-C® / USB PD sink port with a certified hardwired PD stack and patented AUTORUN + HYBRID architecture, with minimal firmware on the host MCU

USB Type-C and USB Power Delivery are moving from personal electronics into white goods, power tools, VR headsets, point-of-sale terminals, and battery-powered industrial equipment, supported by global regulatory momentum and PD Extended Power Range up to 240 W. A USB-C sink port should be able to handle AVS, PPS, EPR, data role swap, VDM, alternate mode, and accessory and cable communication; a full-software stack stretches design cycles, complicates USB-IF and regional certification, and absorbs engineering effort better spent on customer-facing features.

STUSB4531 carries a USB Type-C r2.4 / USB PD r3.2 certified hardwired PD stack with a patented AUTORUN + HYBRID architecture. AUTORUN mode negotiates the power contract with no software, drawing from up to five sink PDO profiles in internal non-volatile memory, suited to DC barrel replacement and automatic charging including dead-battery start-up. HYBRID mode adds a light software layer on a host MCU for advanced USB PD functions, while the hardwired stack handles negotiation, VBUS monitoring, PPS keep-alive, and fault management.
