General Description

Quick Start

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.

Procedure

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

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

The RJ-11 connector provides all signal lines necessary

2

for I 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.

6) 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.

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

Detailed Description of Software

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.

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

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

ModelGauge m5 Tab

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.

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.

corresponding hypothetical Qresidual, TTE, AvSOC, and

AvCap values.

IC Information

The IC Information group box displays information relat-

ed to IC itself. This includes the IC part number, IC unique

ROM ID, and IC ﬁrmware revision.

Graphs Tab

The Graphs tab displays up to 20 ADC readings and fuel

gauge outputs. Figure 5 shows the format of the Graphs

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.

Measurements

The Measurements group box displays ADC measure-

ments that are used by the fuel gauge to determine state

of charge.

Alerts

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.

At Rate

The At Rate group box allows user to input a hypo-

thetical load current and the fuel gauge calculates the

A pop-up window allows the user to enter a new value in

either hexadecimal units or application units. The main

read loop temporarily pauses while the register updates.

Registers Tab

The Registers tab allows the user access to all fuel gauge

related registers of the IC. Figure 6 shows the format of

the Registers tab. By using the two buttons on the left

side of the tab, the user can sort the registers either by

function or by their internal address. Each line of data

contains the register name, register address, hexadecimal

SBS Registers Tab

The SBS registers tab is visible only if SBS functions of the

IC are enabled. The SBS registers tab has the same for-

matting as the standard Registers tab as shown in Figure

7. By using the two buttons on the left side of the tab, the

user can sort the registers either by function or by their

internal address. Each line of data contains the register

1-Wire Communication Speed

Reset IC

This option affects 1-wire ICs only. The user can select

either standard or overdrive communication speed.

Communication speed is controlled by the EV kit software

by driving the OD pin of the IC high or low. Regardless of

the desired communication rate, the kit software commu-

nicates with any IC it discovers at either communication

speed. The actual communication speed is displayed in

the bottom status bar of the EV kit window.

Clicking the Full Reset button sends the software POR

command to the command register and sets the POR_

CMD bit of the Conﬁg2 register to fully reset operation

the same as if the IC had been power cycled. Note that

resetting the IC when the cell is not relaxed causes fuel

gauge error.

Lock Register Blocks

Clicking one of the ﬁve lock buttons locks a page or pages

of memory as listed to the right of each button. This is a

permanent operation so the user is prompted to conﬁrm

the operation prior to setting the lock.

Read/Write Register

The user can read a single register location by entering

the address in hex and clicking the Read button. The

user can write a single register location by entering the

address and data in hex and clicking the Write button.

The read loop is temporarily paused each time to com-

plete this action.

Conﬁguration Tab

The Conﬁguration tab has similar formatting to the stan-

dard Registers tab as shown in Figure 9, but there are

some major differences. When the user changes a register

value on the Conﬁguration tab, only the RAM value of

that location is changed. The nonvolatile value remains

unchanged. Register text changes to BLUE to indicate the

RAM and nonvolatile values do not match. The user must

complete a nonvolatile burn on the Commands tab or run

the Conﬁguration Wizard to change the nonvolatile value.

Log Data to File

Data logging is always active when the kit software is

started. The default data log storage location is the My

Documents/Maxim Integrated/MAX17201_205_211_215/

Datalog.csv. The user can stop data logging by clicking

the Stop Log button or change the data log ﬁle name by

clicking the Change Path button. Whenever data logging

is active, it is displayed on the bottom status bar of the EV

kit window. All user available IC registers are logging in a

.csv formatted ﬁle. The user can adjust the logging inter-

val at any time. The user can also enable or disable the

event logging at any time. When event logging is enabled,

the data log also stores any IC write or reads that are not

part of the normal read data loop and indicates any time

communication to the IC is lost.

The nonvolatile memory has a limited number of updates

that is shown in a box on the left-hand side of the tab.

Maxim recommends using the Conﬁguration Wizard to

make any changes to nonvolatile memory instead of

changing registers manually. The wizard can be launched

through the Device drop-down menu at the top of the EV

kit software window or by the button on the left-hand side

of the Conﬁguration tab. See the Conﬁguration Wizard

section for details.

Burn Nonvolatile Memory Block

Note any register information that is displayed in RED

text indicates a nonvolatile burn error where the data read

back after a burn does not match the expected value.

Clicking the Burn NV Block button sends the Copy NV

Block command to the command register that causes

all register locations from 180h to 1DFh to be stored to

nonvolatile memory. Nonvolatile memory has a limited

number of copies and the user is prompted to conﬁrm

prior to executing the copy.

what it believes the secret value should be. The secret

value cannot be written directly or read from the IC. The

secret value has a limited number of updates that are

displayed in the changes remaining box. Note that once

the secret is locked or if the number of remaining updates

reaches 0, it can no longer be changed.

Authentication Tab

The Authentication tab allows the user to perform any

action related to the SHA 256 authentication feature of the

IC. Figure 10 shows the format of the Authentication tab.

Each group box of the Authentication tab is described in

detail in the following sections.

SHA Challenge/ROM ID

SHA Authentication Results

Enter values into the challenge registers directly or click

the Randomize Challenge button to ﬁll the challenge

registers with a completely random value. The challenge

value is not written to the IC until one of the Compute

MAC buttons is clicked. The ROM ID is used in some SHA

calculations so it is displayed here for reference.

After a SHA operation occurs, the output is displayed in

the Reported MAC column. The EV kit software calcu-

lates its own hash and displays the result in the Expected

MAC column. If the results match, the operation is a suc-

cess. If the results do not match, it is most likely because

the secret inside the IC does not match the secret value

entered into the EV kit software.

SHA Secret

Enter the secret value here to allow software to verify the

SHA calculations of the IC. The EV kit software updates

shows the history tab format.

Generate Challenge/Response Pairs

Some applications use challenge-response pairs to con-

ﬁrm battery pack authenticity instead of maintaining the

secret on the host side. The EV kit software can generate

a ﬁle of any length of random challenge-response pairs

for use by the application. Ensure to have the correct

secret entered before generating the pairs.

Each history page has a status of “BLANK” if it has not yet

been written, “WRITTEN” if it contains good history data,

or “SKIPPED” if the IC experienced a write error while

storing the data. Each history page contains 16 words of

data. The user can click through each of the 203 history

pages or enter a page number directly into the box to

jump to a certain page.

History Tab

The History tab allows the user to see all battery history

logging information stored inside the IC. When the EV kit

software is loaded, this page is blank. History information

is not automatically read from the IC. The user must click

either the Read Battery History button to display history

data or the Read History and Save to File button to store

history data in a tab delimited .csv ﬁle and then display

the data. After history data has been read from the IC,

If a page has been written, all page data is displayed as

hexadecimal values. Some history information can be

converted into application units. Those locations contain

one or two additional boxes of information showing the

converted values. Value boxes can display “User Data”

if that location has been conﬁgured to store user data

instead of history information or “A.F. Data” if that location

is being used for cycle+ age forecasting information.

this procedure.

The second method is ModelGauge m5 EZ conﬁguration.

This is the default characterization information shipped

inside every IC. This default model produces accurate

results for most applications under most operating condi-

tions. It is the recommended method for new designs as

it bypasses the custom cell characterization procedure.

Some additional information is required from the user for

EZ conﬁguration initialization. The Conﬁguration Wizard

tool handles this as well.

ModelGauge m5 EZ Conﬁguration

Before the IC accurately fuel gauges the battery pack, it

must be conﬁgured with characterization information. This

can be accomplished two ways.

The ﬁrst is through a custom characterization procedure

that can be performed by Maxim under certain condi-

tions. The result is an .INI summary ﬁle that contains

can click the previous button in the bottom left corner of

any page to return to any previous step if desired. Once

the last step is completed, the wizard closes, the IC is

conﬁgured, and a new INI ﬁle is saved (if selected).

Conﬁguration Wizard

The EV kit software contains a fuel gauge Conﬁguration

Wizard that can be launched either on the Conﬁguration

tab or from the Device drop-down menu.The Conﬁguration

Wizard is the recommended way to change any nonvola-

tile settings inside the IC. The wizard allows user to:

Step 1: Starting the Template

Choose between the existing nonvolatile memory data

already inside the IC or revert back to the factory default

values (ModelGauge m5 EZ).

● Open a custom INI file or generate a ModelGauge

m5 EZ configuration.

● Make any adjustments specific to the application.

● Load the final configuration into the IC.

Step 2: Cell Model Selection

Choose between existing model already in the IC’s non-

volatile memory, the ModelGauge m5 EZ model, or a

custom model from an INI ﬁle by using the Select File

button. Note that ModelGauge m5 EZ is recommended if

a custom model is not available.

● Export the generated configuration to a new INI file.

The Conﬁguration Wizard walks users through an 18 step

process to conﬁgure the IC. Figure 12 shows the ﬁrst

page of the wizard. Each step is detailed below. The user

applications. Die temperature measurements are enabled by

default if no other measurement channels are enabled..

Step 3: General Pack Conﬁguration

Select the conﬁguration that most closely resembles the

application circuit. The choice made in step 3 determines

which options are available in step 4 as certain functions

and ADC channels are not available in certain pack con-

ﬁgurations.

Step 10: Temperature Measurement Details

Selections made in step 9 determine which options are

available in this step. The user must select which tem-

perature input is used by the fuel gauge. See the nPack-

Cfg register deﬁnition for details. If a thermistor channel is

enabled then gain, offset, and curve scaling values must

be used to convert the ADC reading to temperature. If the

application uses a common thermistor type found in the

pulldown menu, select that thermistor and the scaling val-

ues are automatically populated. If the application does

not use one of these common thermistors, select other

and enter the scaling values manually.

Step 4: Speciﬁc Pack Conﬁguration Details

Select the number of series cells in the pack conﬁgura-

tion as well as which ADC channels are used to measure

pack voltages. If Multicell Inside Protector conﬁguration

was selected in step 3, cell balancing is possible. The cell

balancing threshold can be selected from the drop-down

box. If the application has more than 15 cells in series,

contact Maxim about conﬁguration options.

Step 11: Alert Conﬁguration

Step 5: Shutdown Mode

Enable the desired alert conditions and then select the desired

alert thresholds. Note that the current related alert thresholds

scale based on the sense resistor selection from step 7.

Select the checkbox if the user intends for the IC to enter

shutdown mode any time the battery pack is removed

from the application (communication lines low).

Step 12: Overcurrent Detection

Step 6: SBS Compliant Functionality

Choose the over-discharge (OD) and short-circuit (SC)

detection settings for the application. Each can be enabled

independently of other alerts. The user then selects

a threshold and delay setting. Threshold values scale

depending on the sense resistor selection from step 7.

Select the checkbox if user intends to use IC in smart

battery system (SBS) compliant mode. If SBS mode is not

used, these device registers are available for general-pur-

pose data storage in step 16. If SBS mode is enabled, all

SBS-related conﬁguration settings can be adjusted here.

Step 13: ALRT Pin Polarity

Step 7: Sense Resistor Selection

Choose between active high and active low for the ALRT

pin’s polarity. ALRT pin polarity is forced to active low if

either OD or SC comparators are enabled.

Choose the value of the sense resistor to be used in the

application. Also, select the resistor temperature com-

pensation. Maxim recommends disabling temperature

compensation when using a chip sense resistor. If using a

PCB signal trace as the sense resistor, the default temper-

ature coefﬁcient value of 0.4% per °C is ideal for copper.

Step 14: Cycle+ Age Forecasting

Enable age forecasting here and then choose the

DeadTargetRatio and CycleStart for the age forecasting

function. Note that if age forecasting is enabled, the nVolt-

Temp and nSOC registers are used to store age forecast-

ing information and are not available in step 15.

Step 8: Current Measurement Calibration

(Optional)

Current measurement gain calibration is not required for

proper operation of the fuel gauge. Perform this operation

calibration step only if the application requires it. To cali-

brate current, ﬁrst force a known current of at least one half

the full-scale value through the sense resistor and enter

that value into the Forced Current text box. When the

Current register and AvgCurrent register readings become

stable, the Auto Calibrate button is enabled to allow

calibration to occur. Alternatively, the user can adjust gain

manually by entering a value into the Gain Adjust text box.

The default value for gain adjust is 1.000 or 100%.

Step 15: Battery Life Logging

Enable or disable any of the registers used for Battery Life

Logging. Any unchecked registers not otherwise used by

age forecasting are available for general-purpose data

storage during step 16. The Cycles Per Save box sets

the rate at which cell history information is data logged

by the IC.

Step 16: General-Purpose Data Storage

Conﬁguration choices in steps 1–15 determine which reg-

isters are available for general-purpose data storage. The

user can now enter any data they wish into any nongrey

register location.

Step 9: Temperature Measurement Channels

Select which temperature measurements are used by the appli-

cation. Die temperature measurement is recommended for all

tion shadow RAM and then restart ﬁrmware so that those

changes take effect. This allows the user to experience the

new operation of the IC without using one of the limited

nonvolatile copies. Finally, option three writes the new con-

ﬁguration to the IC, burns the conﬁguration into nonvolatile

memory, and then restarts the IC so those changes take

effect. This option is not available if the IC already used up

all of the available conﬁguration copies. Additionally, the

user can store the new conﬁguration options into a new

INI ﬁle for easy programming of additional units. Select the

desired path name for the new INI ﬁle.

Step 17: Summary of Changes

After all desired nonvolatile conﬁguration settings have

been entered by the user, the table in step 17 shows a

color-coded summary of how the nonvolatile memory

settings are changed by the new conﬁguration. Note the

Conﬁguration Wizard automatically converts any mem-

ory location that matches its alternate default value into

general-purpose data storage. This can cause changes

to the nNVCfg0 to nNVCfg2 registers not selected by the

user, but does not affect IC operation. Figure 13 shows

an example of the Conﬁguration Wizard summary table.

The Conﬁguration Wizard completes once the user clicks

the Done button below step 18. The desired actions from

step 18 occur after Done is clicked and the wizard closes.

Click the window close button in the upper right corner of

the wizard to exit at any time without performing any of the

actions from step 18.

Step 18: Update IC and Save New Conﬁguration

In the ﬁnal step, the user is given options of how to use the

new conﬁguration. Figure 14 shows step 18 of the conﬁgu-

ration wizard. Option one is to discard all changes which

has no effect on the IC. Option two is to write conﬁgura-
