USER GUIDE
UG527: Si82Fx Blinky Demo Board User Guide
The Si82Fx-Blinky is a portable device that helps users
visualize the revolutionary Selectable Variable Current
Drive (SelVCD™) technique, which allows the Si82Fx
IsoDriver to dynamically control its output current at a
constant sourcing or sinking rate. Learn more about
SelVCD™ here.
Blinky demonstrates all eight current "speed" settings
of the Si82Fx via the brightness intensity of an LED
controlled by a rotary switch, with the numbers 0 to 7
indicating lowest-to-highest LED brightness.
Each switch setting activates a connection to a resistor
in an array, which, in turn, connects to the SPD± pins of
the Si82Fx. There is also an "Aux" setting, which allows
for rapid, back-and-forth cycling through all output
current settings of the Si82Fx, thereby causing the LED
to pulsate.
