With the rise of in-vehicle infotainment systems, car manufacturers need to establish reliable and intelligent connections between car displays and multiple smartphones or tablets. Microchip Technology Inc. is the industry leader in providing integrated circuits (ICs) that support such connections, and offers five new USB 2.0 smart hub ICs that offer users a variety of options. These devices are available in a variety of architectures that are flexible enough to adapt to the automotive manufacturer's design needs and meet consumer requirements for easy and intuitive system use.

The five new devices support a variety of architectures, so manufacturers can easily connect their specific designs to all major smartphone operating systems. These systems support the display of the graphical user interface of a mobile phone or tablet on the vehicle's screen, integrated with in-vehicle voice commands, and the ability to charge mobile devices and support the integration of assisted driving applications on the phone with automotive infotainment systems. .
Microchip's new smart hub ICs support hubs cascaded into the second and third rows of seats, and data can be present on all ports simultaneously with charging. For example, if you have two USB ports, one port can connect your phone or tablet to the car's mainframe, and the other port can both charge and upload/download data. Using Microchip's new USB4914, USB4916, USB4925 and USB4927 smart hub ICs, automakers can customize their solutions to meet their design needs. As cars become more and more an entertainment environment, manufacturers can develop innovative solutions that support consumers using one phone for navigation while the other is for listening to music or watching videos.
Mitch Obolsky, vice president of USB and networking products at Microchip, said: "Microchip is the leader in USB hub ICs for the automotive industry. Our long-term commitment to patented technology provides a unique host/device bus configuration for the connection of handheld devices to vehicles. Better access to information for safer assisted driving and communication."
Microchip's new USB4715, USB4914, USB4916, USB4925 and USB4927 USB 2.0 Smart Hub ICs' unique USB configurations include single and dual bus implementations that provide excellent connectivity to infotainment systems. All devices use the standard USB drivers for most automotive host systems to develop and validate systems for field updates. Each device also integrates a 32-bit microcontroller for advanced bridging, audio application support, and USB power (USB PD).
Development support
Application demonstration boards and evaluation boards are available for each new USB 2 smart hub IC. The application demo board simulates a system used by Tier 1 suppliers or original equipment manufacturers (OEMs) in their actual applications. Microchip also demonstrated a USB powered application that charges in accordance with the USB PD 3.0 specification.
There are a few different types of slip rings, but the most common type is called a cap slip ring. Cap slip rings have a cylindrical housing with an internal flange that fits over the end of the shaft. They typically have 6 or 12 channels and are available in a wide range of sizes.
Cap slip rings are used to provide electrical power and signals to and from rotating equipment. The channels on the slip ring allow for the passage of current and/or data signals through the ring. This allows for the rotation of devices such as antennae, radar dishes, and wind turbines without having to interrupt or disconnect the power or signal lines.
Cap slip rings are very reliable and can handle high speeds and heavy loads. They are also easy to install and maintain.
In the modern world, companies are always looking for ways to improve the efficiency of their machines and operations. Oubaibo offers a variety of products that can help improve your machine's performance. Their Cap Slip Ring allows for high-speed rotary unions, while their high-pressure swivel joints can handle even the most strenuous industrial applications. With so many options available, there's sure to be an Oubaibo product that can improve your machine's performance.
