FSUSB46 -- Hi-Speed USB2.0 (480Mbps) DPST Switch with Dedicated Charger Port Detection July 2008 FSUSB46 -- Hi-Speed USB2.0 (480Mbps) DPST Switch with Dedicated Charger Port Detection Features Low On Capacitance: 7.0pF Typical Low On Resistance: 3.9 Typical Low Power Consumption: 1A Maximum Description The FSUSB46 is a bi-directional, low-power, Hi-Speed, USB2.0 switch. Configured as a double-pole, singlethrow switch (DPST) switch, it is optimized for switching a Hi-Speed (480Mbps) source. The FSUSB46 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.9pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. The FSUSB46 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the /OE pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the generalpurpose I/Os of the baseband processor. An additional feature is the detection of the 1-1 (high/high) state on D+/D- to signal an interrupt (INT) to the processor when entering a dedicated charging port mode of operation. - 15A Maximum ICCT over an Expanded Voltage Range (VIN=1.8V, VCC=4.3V) Wide -3db Bandwidth: > 720MHz Packaged in Pb-free, 8-Lead MicroPakTM (1.6mm wide), US8 (3.1mm wide), and UMLP (1.4x1.4mm) 8kV ESD Rating, >16kV Power/GND ESD Rating Power-Off Protection on All Ports When VCC=0V - D+/D- Pins Tolerate up to 5.25V Applications Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.com.
