MAX17263G Evaluation Kit
Evaluates: MAX17263
General Description
The MAX17263G evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
stand-alone ModelGauge™ m5 host-side fuel-gauge ICs
for lithium-ion (Li+) batteries in handheld and portable
equipment.
The MAX17263G EV kit includes the Maxim DS91230+
USB interface, IC evaluation board, and RJ-11 con-
nection cable. Windows
®
-based graphical user inter-
face (GUI) software is available for use with the EV
kit and can be downloaded from Maxim’s website at
www.maximintegrated.com/products/MAX17263
(under the
Design Resources
tab). Windows 7 or newer
Windows operating system is required to use with the EV
kit GUI software.

Procedure
The EV kit are fully assembled and tested. Follow the
steps below to install the EV kit software, make required
hardware connections, and start operation of the kit. The
EV kit software can be run without hardware attached. It
automatically locates the hardware when connections are
made. Note that after communication is established, the
IC must still be configured correctly for the fuel gauge to
be accurate.
1)
Visit
www.maximintegrated.com/products/MAX17263
under the
Design Resources
tab to download the
latest version of the EV kit software. Save the EV
kit software to a temporary folder and unpack the
ZIP file.
Install the EV kit software on your computer by run-
ning the MAX17263_Vx_x_x_Install.exe program
inside the temporary folder. The program files are
copied, and icons are created in the Windows
Start
menu. The software requires the .NET Framework 4.5
or later. If you are connected to the Internet, Windows
automatically updates .NET framework as needed.

3)
The EV kit software launches automatically after in-
stall or alternatively it can be launched by clicking on
its icon in the Windows
Start
menu.
Connect the DS91230+ adaptor to a USB port on the
PC. The DS91230+ is a HID device and is located
automatically by Windows without the need to install
additional drivers.
Make connections to the EV kit board based on cell
pack configuration as shown in
Figure 1.
The load or
charger circuit can be connected at this time as well.
6)
4)
The cell connects between the PACK- and PACK+
pads and the charger/load connects between the
SYSGND and SYSPWR pads. See
Table 1
for jumper
settings for different application scenarios.
Connect the RJ-11 cable between the USB adapter
and the EV kit board. The GUI software establishes
communication automatically.
At power-up, the IC defaults to EZ Configuration. If
you have a custom .INI file for your application, it can
be loaded at this time.

MAX17263G Evaluation Kit
Evaluates: MAX17263
Detailed Description of Hardware
The MAX17263G EV kit board provides a variety of fea-
tures that highlight the functionality of the IC. The follow-
ing sections detail the most important aspects of the EV
kit board.
0Ω jumpers must be resoldered to change the circuit.
Table 2
summarizes the changes. Note that the IC must
be reconfigured to support the new resistor type.
Detailed Description of Software
Communication Connections
The RJ-11 connector provides all signal lines necessary
for I
2
C communication between the IC and the software
GUI interface. When developing code separately, connec-
tions to the communication lines can be made directly to
the SDA, SCL, and GND pins of the board.
The MAX17263G evaluation kit software gives the user
complete control of all functions of the IC, as well as the
ability to load a custom model into the ICs. Separate con-
trol tabs allow the user access to view real-time updates
of all monitored parameters. The software also incorpo-
rates a data-logging feature to monitor a cell over time.
External Thermistor
Software Installation
The IC can be configured to use internal temperature
measurements or an external thermistor. The EV kit
board comes with a thermistor installed as surface mount
component RT1. If the application requires direct thermal
contact to the cells, RT1 can be removed and replaced
with a leaded thermistor connected between the RT1+/
RT1- solder pads (J2 and J3).
The software requires Windows 7 or newer operating
system. .NET version 4.5 is required for operation and is
automatically installed if an older version of .NET frame-
work is detected. To install the evaluation software, exit
all programs currently running and unzip the provided
MAX17263 Installation Package zipped file.
Double click the MAX17263_Vx_x_x Install.exe icon and
the installation process begins. Follow the prompts to
complete the installation. The evaluation software can be
uninstalled in the Add/Remove programs tool in the Control
Panel. After the installation is complete, open the Maxim
Integrated/MAX17263 folder and run MAX17263.exe or
select it from the program menu.
Figure 2
shows a splash
screen containing information about the evaluation kit that
appears while the program is loading.
Sense Resistor Options
The EV kit board is shipped with an 0805 size 0.010Ω
chip sense resistor installed. Oversized land pattern
pads allow for different size sense resistors to be used
if desired. Also, each board contains an optional 0.003Ω
copper trace sense resistor that can be enabled if desired.
To do so, the chip sense resistor must be removed and

Figure 2. EV Kit Splash Screen
Figure 3. EV Kit Bottom Status Bar
Communication Port
The EV kit software automatically finds the DS91230+
adapter when connected to any USB port. Communication
status is shown on the right-hand side of the bottom sta-
tus bar. See
Figure 3.
If the adapter cannot be found, a
“No USB Adapter” message is displayed. If the adapter is
found, but the IC daughter board cannot be found, a “No
Slave Device” message is displayed. Otherwise, if com-
munication is valid, a green bar updates as the software
continuously reads the IC registers.
If the DS91230+ is connected, the status bar should be
active. The bottom status bar also displays information on
data logging status, the communication mode, hiberna-
tion status, selected current-sense resistor value, device
serial number, and the EV kit GUIs version number.
Program Tabs
All functions of the program are divided under four tabs
in the main program window. Click on the appropriate
tab to move to the desired function page. Located on the
ModelGauge m5
tab is the primary user information mea-
sured and calculated by the IC. The
Graphs
tab visually
displays the fuel-gauge register changes over time. The
Registers
tab allows the user to modify common fuel-
gauge registers one at a time. The
Configure
tab allows
for special operations such as initializing the fuel-gauge
logging and performing fuel-gauge reset. All tabs are
described in more detail in the following sections.

ModelGauge m5 Tab
Measurements
The
ModelGauge m5
tab displays the important output
information read from the IC.
Figure 4
shows the format
of the ModelGauge m5 Tab. Information is grouped by
function and each is detailed separately.
The
Measurements
group box displays ADC measure-
ments that are used by the fuel gauge to determine state-
of-charge.
State-of-Charge
Alerts
The
State-of-Charge
group box displays the main output
information from the fuel gauge: state-of-charge of the
cell, remaining capacity, time-to-full, and time-to-empty.
The
Alerts
group box tracks all eleven possible alert
trigger conditions. If any alert occurs, the corresponding
checkbox is checked for the user to see. The clear alerts
button resets all alert flags.
Cell Information
At Rate
The
Cell Information
group box displays information
related to the health of the cell such as the cell’s age,
internal resistance, present capacity, number of equivalent
full cycles, and change in capacity from when it was new.
The
At Rate
group box allows the user to input a hypo-
thetical load current and the fuel gauge calculates the
corresponding hypothetical Qresidual, TTE, AvSOC, and
AvCap values.
