FSUSB46 — Hi-Speed USB2.0 (480Mbps) DPST Switch
with Dedicated Charger Port Detection
Features
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.
Low On Capacitance: 7.0pF Typical
Low On Resistance: 3.9Ω Typical
Low Power Consumption: 1μA Maximum
- 15μA Maximum ICCT over an Expanded Voltage
Range (VIN=1.8V, VCC=4.3V)
Wide -3db Bandwidth: > 720MHz
Packaged in Pb-free, 8-Lead MicroPak™ (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.
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.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
