STMicroelectronics’ STUSB4500 standalone USB Type-C and Power-Delivery
controller extends the convenience and environmental benefits that accompany powering and charging from a uniform USB-C outlet to a good sort of consumer, industrial, and medical products.
Optimized for sink-only applications powered through a USB-C cable, the STUSB4500 may be a certified standalone USB PD controller which will be easily customized by the end-user to suit the appliance .
Based on default power profiles (PDO) loaded in an indoor non-volatile memory, the IC implements proprietary algorithms to barter an influence Delivery contract with a source with none internal support (Auto-run mode), making it the perfect device 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 sorts of portable equipment from 15W to 100W can replace a product-specific charger with a typical USB Type-C connection. These include toys, power tools, vacuum cleaners, office equipment, lighting products, smart speakers, medical devices, and lots of others.
Equipment normally AC-powered through a captive mains cable, like small kitchen appliances, also can cost-effectively become DC-powered to simplify product design, reduce size and weight, and permit the choice of cordless battery-powered operation.
Saving individual dedicated chargers and power supplies by migrating to USB Power Delivery controlled by the STUSB4500 enhances convenience and portability, and mitigates the environmental burden imposed by waste electrical equipment discarded with each product-upgrade cycle. More flexible charging options including fast-charging or charging multi-cell batteries above 5V also are possible.
The STUSB4500 is in production now, within the 4mm x 4mm QFN24 package, priced from $0.75 for orders of 1000 pieces. Engineering samples in a good smaller chip-scale package (CSP) are going to be available from mid-July for the asking .
