| FSUSB31 -- Low-Power, Single-Port, High-Speed USB 2.0 (480Mbps) Switch September 2008 FSUSB31 Low-Power, Single-Port, High-Speed USB 2.0 (480Mbps) Switch Features Low On Capacitance: 3.7pF (Typical) Low On Resistance: 6.5 (Typical) Low Power Consumption: 1A (Maximum) Description The FSUSB31 is a low-power, single-port, high-speed USB 2.0 switch. This part is configured as a double-pole, single-throw switch and is optimized for switching or isolating a high-speed (480Mbps) source or a high-speed and full-speed (12Mbps) source. The FSUSB31 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. 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 minimizes interference. The FSUSB31 contains special circuitry on the D+ / Dpins that allows the device to withstand an over-voltage condition. This device is also 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 for mobile applications, such as cell phones, allowing direct interface with the general-purpose I/Os of the baseband processor. Other applications include port isolation and switching in portable cell phones, PDAs, digital cameras, printers, and notebook computers. - 10A Maximum ICCT Over an Expanded Control Voltage Range: VIN = 2.6V, VCC = 4.3V Wide -3dB Bandwidth: > 720MHz 8kV I/O to GND ESD Protection Power-off Protection When VCC = 0V, D+ / D- Pins Can Tolerate up to 5.5V Packaged in: - 8-lead MicroPakTM (1.6 x 1.6mm) - 8-lead US8 - 8-lead Ultrathin MLP (1.2 x 1.4mm) Applications Cell Phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-top Box Related Resources AN-6022 Using the FSUSB30/31 to Comply with USB 2.0 Fault Condition Requirements Ordering Information Part Number FSUSB31K8X FSUSB31L8X FSUSB31UMX Package MAB08A MAC08A UMLP08A Eco Status Green RoHS Green Package Description 8-Lead US8, JEDEC MO-187, Variation CA 3.1mm Wide 8-Lead MicroPak, 1.6mm Wide 8-Lead, Ultrathin Molded Leadless Package (UMLP), 1.2 x 1.4mm For Fairchild's definition of "green" Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html.

The FSUSB31 can be successfully configured to meet both these requirements. Power-On Protection The USB 2.0 specification also notes that the USB device should be capable of withstanding a Vbus short during transmission of data. Fairchild recommends adding a 100 series resister between the switch VCC pin and supply rail to protect against this case. This modification works by limiting current flow back into the VCC rail during the over-voltage event so current remains within the safe operating range. In this application, the switch passes the full 5.25V input signal through to the selected output, while maintaining specified off isolation on the un-selected pins. Power-Off Protection For a Vbus short circuit, the switch is expected to withstand such a condition for at least 24 hours. The FSUSB31 has specially designed circuitry which prevents unintended signal bleed through as well as guaranteed system reliability during a power-down, overvoltage condition. The protection has been added to the common pins (D+, D-). VCC= 3.6 V 100 Ohms HSD+ HSD- D+ = 5.25V FSUSB31 D- = 5.25V Figure 21. A 100 resistor in series with the VCC supply allows the FSUSB31 to withstand a Vbus short when powered up For more information, see Applications Note AN-6022 -- Using the FSUSB30/FSUSB31 to Comply with USB 2.0 Fault Condition Requirements at www.fairchildsemi.com.
