Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

FSUSB46 — Hi-Speed USB2.0 (480Mbps) DPST Switch with Dedicated Charger Port Detection
March 2013
FSUSB46 — Hi-Speed USB2.0 (480Mbps) DPST Switch
with Dedicated Charger Port Detection
Features
Low On Capacitance: 7.0pF Typical
Low On Resistance: 3.9Ω Typical
Low Power Consumption: 1μA Maximum
Description
The FSUSB46 is a bi-directional, low-power, Hi-Speed,
USB2.0 switch. Configured as a double-pole, single-
throw 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
(C
ON
) 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 V
CC
supply is
powered-off (V
CC
=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 (V
CC
). This feature is especially
valuable to ultra-portable applications, such as cell
phones, allowing for direct interface with the general-
purpose 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.
