General Description
The MAX17058 and MAX17059 evaluation kits (EV kits)
consist of the MAX17058 and MAX17059 evaluation kit
(EV kit) and the Maxim DS91230+ command module.

7-com-
patible operating systems software is also available
for use with the EV kits and can be downloaded from
Maxim’s website at
www.maxim-ic.com/evkitsoftware.
The MAX17058 and MAX17059 EV kits are fully assem-
bled and tested surface-mount PCBs that evaluate the
MAX17058 and MAX17059 host- or battery-side fuel
gauge for single/double-cell lithium-ion (Li+) batteries in
handheld and portable equipment. The EV kits can be
powered from a single battery (MAX17058) and can be
configured to evaluate a single lithium cell (MAX17058)
or two lithium cells in series (MAX17059).

Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold and under-
lined
refers to items from the Windows operating system.
The EV kits are fully assembled and tested. Follow the
steps below to verify board operation.
Caution: Do not
turn on the power supply until all connections are
completed.
1) Connect the DS91230+ board to a spare USB port on
the PC.
2) Connect the RJ12 cord between J2 on the DS91230+
board and J1 on the EV kit.
ModelGuage is a trademark of Maxim Integrated Products, Inc.
3) Verify that shunts are installed according to the
defaults listed in
Table 1.
4) Connect the positive terminal of the power supply or
battery to the BAT+ PCB pad on the EV kit. Connect
the negative terminal of the power supply to the BAT-
PCB pad on the EV kit.
5) Download the latest version of the EV kit software at
www.maxim-ic.com/evkitsoftware,
MAX17058Rxx.
ZIP or MAX17059Rxx.ZIP. Save the EV kit software to
a temporary folder and uncompress the ZIP file.
6) Install the EV kit software on your computer by running
the SETUP.EXE program inside the temporary folder.
The program files are copied and icons are created
in the Windows
Start | Programs
menu. The software
requires the .NET Framework 4. If you are connected
to the Internet, Windows automatically locates the
correct files and walks you through the process. You
can also download the
Microsoft .NET Framework 4
Client Profile (Standalone Installer)
and run that on
your PC.
7) Start the EV kit software by opening its icon in the
Start | Programs
menu.
8) Load the default or custom battery model.
Required Equipment
• +2.5V to +4.5V DC power supply or single-cell battery

MAX17058/MAX17059 Evaluation Kits
Evaluate: MAX17058/MAX17059
Detailed Description of Hardware
The MAX17058/MAX17059 EV kits are fully assem-
bled and tested surface-mount PCBs that evaluate the
MAX17058 and MAX17059 host- or battery-side fuel
gauge for single/double-cell Li+ batteries in handheld
and portable equipment. The EV kits can be powered
from a single supply or battery with an input range of
+2.5V to +4.5V. The EV kit can be configured to evalu-
ate a single lithium cell (MAX17058) or two lithium cells
in series (MAX17059). Optional LDO U2 is provided to
power VIN when using a higher voltage 2-cell Li+ battery
to evaluate the MAX17059.
The MAX17058 EV kit is set by default to evaluate single-
cell Li+ batteries, while the MAX17059 EV kit is set by
default to evaluate 2-cell Li+ batteries. LDO U2 is pro-
vided so that only a single supply is needed to power the
EV kit in the case where a 2-cell battery is used.
When evaluating the MAX17058, set jumper JU1 to pins
1-2 and remove any shunt installed on JU2 to bypass the
LDO. When evaluating the MAX17059, set jumper JU1 to
pins 2-3 and install a shunt on JU2 to power VIN from the
LDO. See
Table 2
and
Table 3
for jumper JU1 and JU2
settings.
Note:
When using a separate supply for VIN or
evaluating the MAX17058, JU2 should be uninstalled to
prevent additional current drawn from the battery.

MAX17058/MAX17059 Evaluation Kits
Evaluate: MAX17058/MAX17059
Detailed Description of Software
The splash screen (Figure
1)
allows you to choose one of
three distinct modes:
• Custom model with physical MAX17058/MAX17059.
Custom models for MAX17040/1/3/4 can be used
in this software provided you change the line:
Device = MAX1704x to Device = MAX17058.
• Default model with physical MAX17058.
Warning:
Using the default model normally results in
poor fuel-gauge performance. For good fuel-gauge
performance, it is recommended to always use a
model that is matched to the battery according to bat-
tery characterization.
• Demo mode with a MAX17058 log file.
Note that the MAX17059 EV kit software is also available
for download at Maxim’s website at
www.maxim-ic.com/
evkitsoftware.
Splash Screen
You can resize the left-right split in the window (Figure
2).
Most major functionality is available from the menu, but
some of the following items should be observed early.
Main Window
Currently Loaded Custom Battery Model
This group displays any custom model that has been
loaded onto the part by the software. If the device resets,
this model is automatically reloaded. If you are using the
default model, nothing is displayed here. Any changes
to the configuration file are not reloaded automatically.
Record Registers to Log File
This group displays the file path to which the software
is recording the registers. If this box is blank, no file is
being saved.
RCOMP Configuration
You can enter a byte here and press the
Write RCOMP
button to write it to the device. This is not the same as
writing the value into the memory map, because RCOMP
is part of a larger 2-byte register.

Figure 2. MAX17058 EV Kit Software (Main Window)
If you have a custom model, you can also change the
temperature, which adjusts the MAX17058 for proper
temperature performance. Changing this value immedi-
ately calculates a new value of RCOMP and displays it in
the box. This value is not written to the device until you
press the
Write RCOMP
button. A change to RCOMP is
not reflected in the temperature.
Memory Map
Notation used for
Name
and
Addr
should be familiar
to C programmers with one small change. The memory
map lists:
• Name: A dot indicates that a single address has mul-
tiple meanings. This is similar to how the C firmware
might access the bits.
• Addr: A colon indicates the 0-indexed location, not
the size of the bit field. A dash indicates a range of
values (e.g., 0x0C:0-4 is a 5-bit value, offset 0 bits at
address 0x0C).
• Hex: The raw value as read directly from the device
• Value: A conversion of the raw hex value, usually with
units. Alert bit flags are blank when inactive, or show
text when they are alerting.
• Description: Reminders of the functionality. For full
details, refer to the MAX17058/MAX17059 IC data
sheet.
You can write values to the device directly through the
memory map. To write a raw hex value, select the cell in
the
Hex
column, overwrite the value, and press the Enter
or Tab key. You will be prompted to write to the device.
Normal communication pauses, and you will see a cor-
responding blank spot in the graph.
For registers with a conversion factor (e.g.,
Hibernate
Threshold
or
VAlertMax),
you can also modify the Value
column. The software converts the value back to the raw hex,
and prompts to verify that you are writing what you expect.
Remember that not all registers are writable.
Plot
The plot can be configured using the
Preferences
window.
The plot is interactive. You can zoom into the
Time
axis
by left-clicking and dragging anywhere in the plot area.
You will see the region highlighted as you drag. You can
zoom out either by pressing the small button in the bot-
tom left, or by right-clicking in the plot area.
Plotted information not in a log file cannot be recovered
once the application closes.
