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.

The splash screen (Figure 1) allows you to choose one of
three distinct modes:
1) Custom model with physical MAX17048 / MAX17049.
2) Default model with physical MAX17048. Warning:
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).
Custom models for MAX17040 –MAX17044 can be
used in this software provided you change the line
Device = MAX1704x to Device = MAX17048.
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.
