Status: In Production
The Microchip USB24926C is a USB2.0 Hi-Speed Hub with unique Smart Hub features targeted to automotive consumer ports and head unit applications. The USB24926C 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, Type C interface, 15W Type C support, LED lighting, and an embedded 32 bit micro-controller for the implementation of USB IO bridging and thermal management. 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.
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 the 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.
Standard USB drivers, which are native to the operating system, are utilized to execute device operation. No custom drivers are required. .
