General Description
Evaluate: MAX17201/MAX17211
The MAX17201G/MAX17201X/MAX17211G/MAX17211X
evaluation kits (EV kits) are fully assembled and test-
ed surface-mount PCBs that evaluate the stand-alone
ModelGauge™ m5 pack-side fuel-gauge ICs for lithium-
ion (Li+) batteries in handheld and portable equipment.
The MAX17201 and MAX17211 are for single-cell appli-
cations. See the MAX17205 and MAX17215 for multicell
applications.
The MAX17201G/MAX17201X/MAX17211G/MAX17211X
EV kits include the Maxim DS91230+ USB interface, IC
evaluation board, and RJ-11 connection cable. Windows
®
based graphical user interface (GUI) software is avail-
able for use with the EV kit and can be downloaded from
Maxim’s website
www.maximintegrated.com/evkitsoft-
ware.
Windows 7 or newer Windows operating system is
required to use with the EV kit GUI software.

Fully Assembled and Tested
The EV kits are fully assembled and tested. Follow the
steps below to install the EV kit software, make required
hardware connections, and start operation of the kits. 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. See the
Configuration Wizard
and
ModelGauge m5 EZ Configuration
sections of the GUI
software description.
1)
Visit
www.maximintegrated.com/evkitsoftware
to
download the latest version of the MAX17201_05_11_15K
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 MAX17201_05_11_15K_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.
The EV kit software launches automatically after in-
stallation or alternatively it can be launched by click-
ing on its icon in the Windows
Start
menu.
Connect the DS91230+ adapter 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.

5)
Make connections to the EV kit board based on cell
pack configuration as shown in
Figure 1.
The cell
connects between the BAT- and BAT+ pads and the
charger/load connect between the PACK- and PACK+
pads. The load or charger circuit can be connected at
this time as well.

Communication Connections
Connect the RJ-11 cable between the USB adapter
and the EV kit board. The GUI software establishes
communication automatically.
7)
If the IC has not been configured, run the Configura-
tion Wizard in the EV kit software to configure op-
eration for the desired application circuit and lithium
cell type. Configuration information is permanently
saved inside the IC.
6)
The RJ-11 connector provides all signal lines necessary
for I
2
C, SMBus, 1-Wire, or 1-Wire overdrive communica-
tion between the IC and the software GUI interface. When
developing code separately, connections to the commu-
nication lines can be made directly to the board.
Table 1
summarizes the connections that should be made. The
user must apply the appropriate external pullup resistors
to the communication lines when not using the DS91230+
communication interface.
External Thermistors
The MAX17201/MAX17211 can be configured to use up
to two external thermistors. All EV kit boards come with
these thermistors installed as surface mount components
RT1 and RT2. If the application requires direct thermal
contact to the cells, RT1 and RT2 can be removed and
replaced with leaded thermistors connected between the
RT1+/RT1- and RT2+/RT2- solder pads.

Sense Resistor Options
All EV kit boards are 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 0Ω
jumpers must be resoldered to change the circuit.
Table 2
summarizes the changes for each board type. Note that
the IC must be reconfigured to support the new resistor
type. See the
Configuration Wizard
section for details.

Detailed Description of Software
The MAX17201G/MAX17201X/MAX17211G/MAX17211X
evaluation kit software gives the user complete control of
all functions of the MAX17201/MAX17211, as well as the
ability to load a custom model into the ICs. It also comes
with a sophisticated Configuration wizard to allow user to
easily adjust fuel gauge settings. Separate control tabs
allow the user access to view real-time updates of all
monitored parameters. The software also incorporates a
data-logging feature to monitor a cell over time.

Software Installation
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
MAX17201_05_11_15K Installation Package zipped file.
Double click the MAX17201_05_11_15K_V_x_x_x_x
Install.exe icon and the installation process begins.
Follow the prompts to complete the installa-
tion. 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/MAX17201_05_11_15K folder and run
MAX17201_05_11_15K.exe or select it from the pro-
gram menu.
Figure 2
shows a splash screen containing
information about the evaluation kit that appears as the
program is being loaded.
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 EVKIT GUI’s version number.

Program Tabs
All functions of the program are divided under eight 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
measured and calculated by the IC. The
Graphs
tab
visually displays fuel gauge register changes over time.
The
Registers
and
SBS
registers tabs allow the user to
modify common fuel gauge registers one at a time. The
Commands
tab allows for special operations such as
changing communication mode, initiate fuel gauge log-
ging and performing fuel gauge reset. The
Configuration
tab displays the value of the nonvolatile registers as
well as the remaining number of available writes. The
Authentication
tab displays SHA authentication-related
information. The
History
tab allows the user to read out
and save battery history information logged by the IC over
its lifetime. All tabs are described in more detail in the fol-
lowing sections.

ModelGauge m5 Tab
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.
State of Charge
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.
Cell Information
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.

Tab. Graph information is grouped into four categories:
voltages, temperatures, capacities, and currents. The
user can turn on or off any data series using the check
boxes on the right-hand side of the tab. The graph visible
viewing area can be adjusted from 10 minutes up to 1
week. The graphs remember up to 1 week worth of data.
If the viewing area is smaller than the time range of the
data already collected, the scroll bar below the graphs
can be used to scroll through graph history. All graph
history information is maintained by the program. Graph
settings can be changed at any time without losing data.
