Description
The FAN5617 Evaluation Board is a compact circuit
including the FAN5617 in a 3x3mm 16-pin MLP package.
LED brightness is controlled via a simple one-wire digital
interface. The evaluation board includes a USB interface
with mini-B receptacle for easy connection to a PC. A
"dashboard" program is provided on an installation CD to
set the LED brightness using the TinyWire
TM
interface. The
FAN5617 evaluation board, a completely assembled and
tested surface mount board, provides easy probe access
points to all inputs and outputs so that electrical
characteristics and waveforms can be easily measured.

FAN5617 Evaluation Board
USB Type A to Mini-B Data Cable
Software Installation CD
PC System Requirements
A PC or Laptop running Windows 2000 or Windows XP with
an available USB port connection. USB 2.0 is required for
the FAN5617 to run from USB-power. USB 1.1 may be
used with an external power supply to run the FAN5617
(see Power Options on next page).
Set-up and Installation Procedure
1. Insert the CD-ROM. If the installation program does not
run automatically, run Setup.exe, which is in the root
directory of the CD-ROM.
If you choose to run the program after installation, and
before completing step #2 below, you will get an error
message.
2. Connect the USB cable between the eval board and
PC. Windows should then find the device and attempt
to install the driver.
3. Connect any external power supplies, if desired. The
FAN5617 eval board can be powered from the USB
cable if USB 2.0 is used.
4. Run the software: “FAN5617 TinyWire Control Panel"
