PI3USB223 USB 2.0 High-Speed and Audio Switches with Negative Signal Capability Features Description * * * * * * The PI3USB223 combines AC coupled audio signals and USB2.0 HS (480Mbps) on the same pins. This enables users to use a single connector to drive either a USB end point or an audio end point. Single +2.7V to +4.4V Supply Voltage Low 50A Supply Current -3dB Bandwidth: 1500MHz (typ) Low 2.5(typ)On-Resistance THD+N: 0.02% Shorting D+/R and D-/L to Vbus will not cause leakage when VDD = 0 * Internal Shunt Resistors for Click-and-Pop Reduction * VBUS Detection for Automatic Switch Path Selection * Packaging (Pb-free & Green available): = 10-pin contact UQFN, 1.4 x 1.8, (ZM10) PI3USB223 incorporates gate pump technology required to maintain low Ron for ideal audio THD while reducing the capacitance affect of high speed USB signals. The device also incorporates a substrate pump technology which allows -2V signals to pass through the switch without causing any leakage. The PI3USB223 features protection on D+/R and D-/L to ensure no damage will happen to the IC if these pins are shorted accidentally to Vbus as well as ensuring there is no leakage when VDD is on or off. Also, it includes VBUS detection (VB) to automatically switch to the USB signal path upon detection of a valid VBUS signal. It also features internal shunt resistors on the audio path to reduce clicks and pops heard during output. The device is available in a space-saving 10-pin, 1.4mm x 1.8mm UQFN package, and operate over the -40C to +85C temperature range.
