To help with their implementation, developers can use our standalone STUSB4500 USB PD controller for power sinking devices. The STUSB4500 is tiny, safe, certified, and easily customizable. It can be powered only from VBUS, therefore not sinking any current locally, preserving the battery lifetime. Our EVAL-SCS001V1 reference design ensures a fast and easy migration from DC barrel to Type-C ports. An STUSB4500 evaluation board (STEVAL-ISC005V1) is also available to help developers get started. Schematics and source code examples can also be downloaded.
