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.
