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. The RJ-11 connector provides all signal lines necessary for I2C, SMBus, 1-Wire, or 1-Wire overdrive communication between the IC and the software GUI interface. When developing code separately, connections to the communication 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 Configuration Wizard in the EV kit software to configure operation 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.

Figure 8 shows the format of the Commands tab. Each group box of the Commands tab is described in detail in the following sections. Figure 8. Commands Tab www.maximintegrated.com Maxim Integrated │  8 MAX17201G/MAX17201X/ MAX17211G/MAX17211X Evaluation Kits 1-Wire Communication Speed 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 communicates 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. 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 complete this action. 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 interval 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. Burn Nonvolatile Memory Block 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. www.maximintegrated.com Evaluate: MAX17201/MAX17211 Reset IC 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. Configuration Tab The Configuration tab has similar formatting to the standard 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. 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. 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.

Configuration Tab 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 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. SHA Secret Enter the secret value here to allow software to verify the SHA calculations of the IC. The EV kit software updates www.maximintegrated.com these values after a compute next secret command to 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. SHA Authentication Results After a SHA operation occurs, the output is displayed in the Reported MAC column. The EV kit software calculates its own hash and displays the result in the Expected MAC column. If the results match, the operation is a success. 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.

Authentication Tab Generate Challenge/Response Pairs Some applications use challenge-response pairs to confirm 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. 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, www.maximintegrated.com it is displayed to the user starting with page 1. Figure 11 shows the history tab format. 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. 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. Maxim Integrated │  11 MAX17201G/MAX17201X/ MAX17211G/MAX17211X Evaluation Kits Evaluate: MAX17201/MAX17211 Figure 11. History Tab The history information is also displayed in a graph on the left side of the tab. The graph displays data only from history pages that have been written by the IC. Click on the corresponding register name button to change the data shown by the graph. 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 conditions. The result is an .INI summary file that contains www.maximintegrated.com information that can be programmed into the IC using the Configuration Wizard tool. Contact Maxim for details on 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 conditions. 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. Maxim Integrated │  12 MAX17201G/MAX17201X/ MAX17211G/MAX17211X Evaluation Kits 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 nonvolatile settings inside the IC. The wizard allows user to: Evaluate: MAX17201/MAX17211 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). Step 1: Starting the Template ●● Open a custom INI file or generate a ModelGauge m5 EZ configuration. Choose between the existing nonvolatile memory data already inside the IC or revert back to the factory default values (ModelGauge m5 EZ). ●● Make any adjustments specific to the application. Step 2: Cell Model Selection ●● Load the final configuration into the IC. ●● 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 Choose between existing model already in the IC’s nonvolatile 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. Figure 12.

Die temperature measurements are enabled by default if no other measurement channels are enabled.. 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 configurations. Step 10: Temperature Measurement Details Select the number of series cells in the pack configuration 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. Selections made in step 9 determine which options are available in this step. The user must select which temperature input is used by the fuel gauge. See the nPackCfg 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 values are automatically populated. If the application does not use one of these common thermistors, select other and enter the scaling values manually. Step 5: Shutdown Mode Step 11: Alert Configuration Step 4: Specific Pack Configuration Details 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). 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. Step 6: SBS Compliant Functionality Step 12: Overcurrent Detection 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-purpose data storage in step 16. If SBS mode is enabled, all SBS-related configuration settings can be adjusted here. 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. Step 7: Sense Resistor Selection Step 13: ALRT Pin Polarity Choose the value of the sense resistor to be used in the application. Also, select the resistor temperature compensation. Maxim recommends disabling temperature compensation when using a chip sense resistor. If using a PCB signal trace as the sense resistor, the default temperature coefficient value of 0.4% per °C is ideal for copper. 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 calibrate 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 9: Temperature Measurement Channels Select which temperature measurements are used by the application. Die temperature measurement is recommended for all www.maximintegrated.com 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. 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 nVoltTemp and nSOC registers are used to store age forecasting information and are not available in step 15. 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 registers are available for general-purpose data storage. The user can now enter any data they wish into any nongrey register location. Maxim Integrated │  14 MAX17201G/MAX17201X/ MAX17211G/MAX17211X Evaluation Kits 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 memory 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. 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 configuration wizard. Option one is to discard all changes which has no effect on the IC. Option two is to write configura- Evaluate: MAX17201/MAX17211 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 configuration 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. 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. Figure 13.
