Functional Description
The FSA806 USB2.0 accessory switch is designed to
consolidate wired accessories for portable devices, such
as cellular telephones and portable audio players. The
benefits
of
consolidation
include
reduced
space
requirements from a reduction of connectors and their
size. The micro-USB connector, for example, reduces
connector height and depth, allowing for slimmer overall
designs. Using the USB industry standard and a common
connector type, for accessories such as chargers and
headsets, greatly reduces the waste associated with new
phone purchases by allowing re-use of the accessories.
Using just five wires for all connection types
considerably reduces the cost of wired accessories and
simplifies their construction. The FSA806 facilitates
adopting this methodology because it is designed to
redirect the DP/DM pins from the USB connector to one
of three ports at the baseband’s discretion.
Applications with Multiple USB Controllers
When operating with two USB controllers, it is
recommended to configure the switches to OPEN before
switching to the other (second) USB interface. The
OPEN setting duration should be long enough for the
accessory to go to a SE0 state, when the switch is set to
the other (second) USB port, the new controller re-
enumerates.
