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. This patented hybrid mode simplifies the implementation of optional USB PD features, adding value to USB-powered and USB-chargeable devices. This mode allows an external application processor to interact with the stack and leverage the USB PD protocol layers. This feature gives engineers extra flexibility to implement functions such as battery messaging, data role swapping, Alternate modes, and vendor-defined messages (VDM) while also easing software development and accelerating time to market.
