GUI APPLICATION
Introduction to the GUI
The LTC3337 GUI provides a graphical interface for some
of the main features of the LTC3337. In addition, it pro-
vides an advanced debugging interface that can be used
in evaluating operation of the DC2973A as well as a cus-
tomer's own design.
To use the DC2973A, the PC must first have the proper
software driver and GUI installed. Download the QuikEval
software from www.analog.com
software by running the executable ltcqev.exe. Follow the
instructions to connect the DC2973A.
For more detail on GUI functions, launch the GUI and go
to Window ➝ Show Help Guide.
GUI Layout
The LTC3337 GUI is divided into a Dashboard tab, an
Engineering tab, and a Schematic tab. The Dashboard
tab shows a graphical representation of a some of the

LTC3337's core functionality. The Engineering tab shows
all registers and is intended to be used for lower-level
development and debugging purposes. The Schematic
tab just displays the schematic for reference.
Dashboard Tab
The Dashboard tab shows all the basic information
needed to monitor a battery's state of charge. Along with
the accumulated charge information, the battery voltage,
series resistance, and average current are also shown.
While the dashboard is open, the GUI reads data from the
LTC3337 every 200ms.
To set up a battery for SoC measurement, click the Battery
Setup button in the bottom-left corner. From there, con-
figure your battery settings as required and click the Start
button. This sets a target accumulated charge value at
which the remaining capacity of the battery is considered
to be 0%. After starting the test, intermediate calculations
can be viewed by showing the Console window.
