MAX17048/MAX17049 Evaluation Kits
Evaluate: MAX17048 /MAX17049
General Description
The MAX17048/MAX17049 evaluation kits (EV kits)
consist of the MAX17048/MAX17049 evaluation kit
(EV kit) and the Maxim DS91230+ command mod-
ule. A Windows XP
M
-, Windows Vista
M
-, and
Windows
M
7-compatible software is also available for
use with the evaluation kits and can be downloaded from
www.maxim-ic.com/evkitsoftware.
The EV kits are fully assembled and tested surface-mount
PCBs that evaluate the MAX17048/MAX17049 host or
battery-side fuel gauge for 1-cell/2-cell lithium-ion (LI+)
batteries in handheld and portable equipment. The EV
kits can be powered from a single battery (MAX17048)
and can be configured to evaluate a single lithium cell
(MAX17048) or two lithium cells in series (MAX17049).

Quick Start
• MAX17048 / MAX17049 EV kits
• DS91230+ PicBrick board
• RJ12 6pos-6pos reverse modular cord
• Windows XP, Windows Vista, or Windows 7 PC
• USB port
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.
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

5) Visit
www.maxim-ic.com /evkitsoftware
to download
the latest version of the MAX17048 or MAX17049 EV
kit software, MAX17048Rxx.ZIP /MAX17049Rxx.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.

MAX17048/MAX17049 Evaluation Kits
Evaluate: MAX17048 /MAX17049
Detailed Description of Hardware
The MAX17048/MAX17049 EV kits are fully assembled and
tested surface-mount PCBs that evaluate the MAX17048 /
MAX17049 host or battery-side fuel gauge for 1-cell /2-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 kits can be
configured to evaluate a single lithium cell (MAX17048)
or two lithium cells in series (MAX17049). Optional LDO
U2 is provided to power VIN when using a higher voltage
2-cell Li+ battery to evaluate the MAX17049.
The MAX17048 EV kit is set by default to evaluate 1-cell
Li+ batteries, while the MAX17049 EV kit is set by default
to evaluate 2-cell Li+ batteries. LDO U2 is provided so
that only a single supply is needed to power the EV kit in
the case a 2-cell battery is used.
When evaluating the MAX17048, set jumper JU1 to pins
1-2 and remove any shunt installed on JU2 to bypass the
LDO. When evaluating the MAX17049, set jumper JU1
to pins 2-3 and install a shunt on JU2 to power VIN from
the LDO. See Tables 2 and 3 for jumper JU1 and JU2
settings. Note that when using a separate supply for VIN
for evaluating the MAX17048, JU2 should be uninstalled
to prevent additional current drawn from the battery.
Detailed Description of Software
The splash screen (Figure 1) allows you to choose one of
three distinct modes:
1) Custom model with physical MAX17048 / MAX17049.
Custom models for MAX17040 –MAX17044 can be
used in this software provided you change the line
Device = MAX1704x to Device = MAX17048.
2) Default model with physical MAX17048.
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
battery characterization.
3) Demo mode with a MAX17048 log file.
Note:
The MAX17049 EV kit software is also available for
download at
www.maxim-ic.com/evkitsoftware.
You can resize the left-right split in the window. Most
major functionality is available from the menu, but some
of these items should be observed early (see Figure 2).
