Standalone USB Type-C Power-Delivery controller
The controller is optimised for sink-only applications powered through a USB-C cable, is a certified standalone USB PD controller and can be customised for individual applications.
Based on default power profiles (PDO) loaded in an internal non-volatile memory, the IC implements proprietary algorithms to negotiate a Power Delivery contract with a source without any internal support (Auto-run mode), making it ideal for automatic high-power-profile charging especially from a dead-battery power state. An application processor can then optionally and dynamically change STUSB4500 power profiles to force another negotiation.
The STUSB4500 supports multiple options to manage multiple input power paths and irrelevant power sources. The device is in production now, in a 4mm x 4mm QFN24 package.
