STUSB4531 addresses USB Type-C® sink devices. Based on default PDO configuration stored in an internal non-volatile memory, STUSB4531 implements proprietary algorithms to negotiate a power delivery contract with a source without any software support (autorun mode), making it the ideal device for automatic high power profile charging, especially from a dead battery power state. STUSB4531 also implements a simple interface (hybrid mode) to support full feature applications with a light external software layer. https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2025-10-15 https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2025-10-24 https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2025-11-03 https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2026-02-22 https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2026-05-28 https://elecena.pl/product/29430133/stusb4531qtr-standalone-usb-pd-controller-for-power-sinking-devices 2026-06-25
