The STUSB4500 is a stand-alone USB PD controller certified by the relevant industry. It is optimized for the power-receiving application using a USB-C cable. Users can easily customize the STUSB4500 settings according to their own application scheme.
Based on the default power profile (PDO) stored in the internal non-volatile memory, the STUSB4500 controller executes ST's proprietary algorithms to negotiate the transmission protocol with the power supply without any internal support (automatic mode). It is ideal for automatic high-power profile charging, especially for charging non-powered batteries. Then, the application processor can choose to dynamically modify the STUSB4500's power profile to force another power-conference negotiation dialog.
The STUSB4500 supports multiple options to manage multiple input power channels and unrelated power supplies. With this controller built in, many 15W to 100W portable devices can replace dedicated chargers with a standard USB Type-C interface. These devices Including toys, power tools, vacuum cleaners, office equipment, lamps, smart speakers, medical equipment, etc.
The STUSB4500 also enables small appliances such as small appliances connected to an AC power supply via a power cord to be converted into DC equipment at a low cost, thereby simplifying product design, reducing size, and reducing weight. It can also be turned into a battery-powered wireless device. Electrical appliances.
By upgrading the device to USB transmission through the STUSB4500 controller, the device can eliminate the need for a separate dedicated charger and power supply, improve the convenience of use and carrying, and reduce the environmental pressure caused by the waste electrical appliances after each product upgrade. STUSB4500 controller can also Achieve more flexible charging options, including fast charging or charging a battery pack above 5V.
The STUSB4500 is now available in a 4mm x 4mm QFN24 package. From mid-July, users can request engineering samples in smaller wafer-level packages.
