STMicroelectronics STUSB4531 Standalone SINK USB PD Controller
STMicroelectronics STUSB4531 Standalone SINK USB PD Controller addresses USB Type-C® sink devices. Based on the default PDO configuration stored in an internal non-volatile memory, the STUSB4531 implements proprietary algorithms to negotiate a power delivery contract with a source without requiring software support (autorun mode), making it an ideal device for automatic high-power profile charging, especially from a dead battery power state.
The STMicroelectronics STUSB4531 also implements a simple interface (hybrid mode) to support full-feature applications with a light external software layer.
