<p>The Microchip USB24926P is a USB2.0 Hi-Speed Hub with unique Smart Hub features targeted to automotive consumer ports and head unit applications. The USB24926P is compliant with the USB 2.0 Specification and has passed AEC-Q100, Grade 2 testing. This highly integrated chip optimizes board area and reduces overall system costs, with the incorporation of leadership functionality, including; Dual UpSTream (DUST) architecture, battery charging support for industry profiles, power delivery support (USB PD30.), security, LED lighting, and an embedded 32 bit micro-controller for the implementation of USB IO bridging and USB Power Delivery. The multiple downstream USB ports support USB2.0 Low Speed/Full Speed/Hi-Speed with a single USB2.0 Hi-Speed upstream port for host connection.</p> <p>The Dual UpSTream architecture incorporates two USB Hubs into a single-chip device. The two upstream ports connect to a USB Host Port and a USB OTG/Device port. All four downstream facing ports can be configured to the second, single-port USB hub, while the other three ports remain attached to the original USB Host. By providing the capability to activate a second USB network through internal muxing, dedicated bandwidth is assured for single-port USB hub. This capability can be used in delivering solutions for smart phones that require host / device swapping during the set-up of an automotive session, where the mobile device becomes the USB Host and manages the graphic user interface on the head unit display. </p> <p>Standard USB drivers, which are native to the operating system, are utilized to execute device operation. No custom drivers are required. . </p> <p>Contact your Microchip local sales support for information on support documents, demonstration application boards, configuration software, datasheet and application notes. </p>
