Providing the interface between automotive infotainment systems and smartphones, the four-port USB84604 IC features the company’s FlexConnect technology and an upstream port that supports both USB 2.0 and High Speed Interchip (HSIC) connectivity. The device’s downstream port one is able to swap with the upstream host port to transfer the host capability to the product connected to the UCH2, such as smartphones and tablets. It can attach to an upstream port as either a full-speed hub or as a full-/high-speed hub. When connected to a high-speed host, the four downstream-facing ports can operate at low speed (1.5 Mbps), full speed (12 Mbps), or high speed (480 Mbps). Additionally, the USB84604’s integrated battery-charger-detection circuitry supports both downstream battery detection and charging, providing the ability to replace external battery chargers with advanced battery-charging modes such as USB-IF Battery Charging (BC1.2) and Apple. The four-port USB84604 UCH2 in a 64-pin QFN package is available today for sampling and volume production, with prices starting at $5.44 each/10,000.
