21ic News STMicroelectronics (ST) has released a new USB Type-C and power transmission interface chip solution. At present, computers, mobile phones, tablets, televisions, set-top boxes, game consoles, various consumer electronics, industrial control equipment and IoT devices are everywhere in the office and home. However, different types of chargers, power lines, and data lines are mutually Winding, often makes the office and the room look messy, and ST's interface chip helps solve this problem.

The USB Type-C interface and the new Power Delivery standard modify the USB subsystem to transform it from a data-capable data interface to a major power interface, while still being market-tested and widely used. Data interface. The USB Type-C interface provides forward and reverse insertion, bidirectional transmission of power, data transfer rates of up to 10Gbps, and maximum transmission power of 100W, making it ideal for consolidating large numbers of cables.
STUSB16 interface chip adopts STMicroelectronics' 20V manufacturing process, integrates short-circuit, over-voltage, over-current and other protection functions, no external circuit is required, and also provides plug-in power support (VCONN) with current setting value up to 600mA, according to USB USB Power Delivery, which integrates the encoding and decoding logic of the Physical Layer (Physical Layer) of the Bi-Phase Mark Coded (BMC).
Andrea Onetti, vice president and general manager of the MEMS products division of STMicroelectronics, said: "I know the dilemma of being surrounded by countless cables and having limited inter-device capabilities. As a director of the USB-IF Association, USB Active participants in the Developer Forum, STMicroelectronics is actively building a strong and flexible portfolio of USB Type-C and power transmission solutions, including STM32 microcontrollers, ESD protection devices, and power management products. The new STUSB16 series Built with more advanced circuit protection features and customizable non-volatile memory, the chip can be configured for charging without software support. The STMicroelectronics portfolio provides equipment manufacturers with a low component cost (BOM) and design. Flexible hardware and software solutions to meet the needs and customization needs of each power class."
By adding STUSB16 companion chips to existing microcontroller-based designs, STMicroelectronics allows device vendors to upgrade to USB Type-C interfaces while significantly reducing application-to-microcontroller-related resources compared to other solutions. demand. These technical features are combined to not only simplify software development, reduce time-to-market, but also allow customers to focus on developing differentiated products with added value.
STMicroelectronics has begun offering samples of the STUSB1600QTR, the first product in the STUSB16 series, to major customers.
