Fairchild Semiconductor’s USB Technology Differentiates Mobile Designs

USB has become the universal interface for mobile applications.
The USB port has evolved from a pure data portal to a means for
file transfers, battery-charging, music listening and factory
programming. To better support the industry’s convergence into one
connector, Fairchild’s new USB transceiver and USB accessory
detection switch bring functional enhancements without adding
design complexity or increasing space and power in mobile
designs.
Through its signal path expertise, Fairchild’s micro-USB switch
(FSA9280A) and USB transceiver (FUSB2500) bring significant design
advantages to the mobile space:
- Auto Detection. The
FSA9280A automatically detects accessories and configures the
proper path for each accessory. This device can detect every
accessory and charger in the market, and has a number of “reserved”
resistors to accommodate new accessories such as glucometers,
e-frames and audio docks. The FUSB2500 has an integrated charger
detect that allows detection without additional component
count.
- Power Savings. The
FSA9280A uses advanced sampling methods to minimize power
consumption in the standby state, extending battery life. It also
provides a negative switch capability in audio applications without
consuming power; alternative solutions need a charge pump for this.
Both the FSA9280A and FUSB2500 offer a low power down function that
puts the device in standby when functions are not in use.
- Audio Fidelity.
Leveraging Fairchild’s signal and audio expertise, the FSA9280A
features exceptionally low Total Harmonic Distortion (THD) of 0.1
percent to optimize performance.
- Robust Protection
Functions. The FSA9280A features many built-in protection
functions and the FUSB2500 offers exceptionally high ESD
protection, 15kV HBM, exceeding the 2kV standard.
- Space-Savings. By
integrating a MOSFET and USB IP into one IC, the FSA9280A
eliminates at least five additional components and reduces Bill of
Material (BOM) costs.
All of these design attributes are instrumental in delivering a
rich user experience. The FSA9280A allows for every conceivable
form of accessory and five future definable accessories, ushering
in a full multi-media experience. The FSA9280A packs data,
charging, audio, headset and other accessory connectivity into one
solution. Through its careful optimization of power, both of these
products feature a power saving mode to help extend battery life
for digital still cameras, portable medical and mobile
applications. Through its audio expertise, Fairchild maintains
signal integrity while adding new functionality. And by integrating
and packing performance into small packages, Fairchild offers the
smallest designs possible.
Fairchild’s USB expertise, combined with its broad portfolio of
USB switches, USB transceivers and audio products, brings
innovation in mobile designs. Fairchild was the first to develop
USB switches and has been supporting USB transceivers for more than
a decade. Fairchild will continue to invest in USB solutions that
advance mobile designs and enrich the user experience.
