STMicroelectronics’ STUSB4500 standalone USB Type-C and Power-Delivery controller extends the environmental benefits that come with powering and charging from a standardized USB-C outlet to a wide variety of products. Optimized for sink-only applications powered through a USB-C cable, the device is a certified standalone USB PD controller that can be easily customized by the end-user to suit the application.
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 viable 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. With this device on-board, numerous types of portable equipment from 15W to 100W can replace a product-specific charger with a standard USB Type-C connection.
Equipment normally AC-powered through a captive mains cable, such as small kitchen appliances, can also cost-effectively become DC-powered to simplify product design. The STUSB4500 is in production now, in a 4 mm x 4 mm QFN24 package, priced from $0.75 each/1,000. Engineering samples in an even smaller chip-scale package (CSP) will be available from mid-July on request. The STUSB4500 evaluation board (STEVAL-ISC005V1) is available for $49.For more information, checkout the datasheet.
