1 MAX/MAX Evaluation Kit Evaluates: MAX/MAX General Description The MAX/MAX evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX/MAX. The EV kit allows for easy evaluation of the various MAX/ MAX features, including the SIMO buck-boost regulator, linear regulator, analog multiplexer, smart battery charger, on/off controller, and IC interface. The MAX and MAX EV kits are identical aside from the device (U), silkscreen, and two resistive dividers at the SIMO outputs (see the MAX/ MAX EV Kit Differences section). The MAX/ MAX devices themselves have different output voltage ranges for the SIMO buck-boost regulator. Consult the device data sheet for more information. Windows -based software provides a user-friendly graphical interface as well as a detailed register-based interface to exercise the features of the MAX/MAX. Ordering Information appears at end of data sheet.

7 MAX/MAX Evaluation Kit Evaluates: MAX/MAX Quick Start Follow this procedure to familiarize yourself with the EV kit. 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 underlined refers to items from the Windows operating system. Required Equipment MAX/MAX EV kit Windows-based PC Power supply Ammeter DVM Micro-USB cable GUI Procedure ) Install the GUI software. Visit the product webpage at /maxevkit and navigate to Design Resources to download the latest version of the EV kit software. Save the EV kit software to a temporary folder and decompress the ZIP file. ) Install EV kit shunts per Table. ) Connect a Micro-B USB cable between the EV kit s J and your Windows-based PC. Note that a USB cable should always be plugged in during evaluation. ) Apply a.v supply (set for ma current limit) through an ammeter (set for ma range) across the VBATT and terminals of the EVKIT. Turn the supply on. ) Open the GUI and press the Connect button in the upper-left corner. Wait for the device to respond, and in the Synchronize window, press the Read and close button. ) Press the on-key (SW) for approximately second, then release the on-key. ) On the AMUX/ADC tab of the GUI, click the Read buttons next to VSBB, VSBB, VSBB, and VLDO. For the MAXA,.V,.V,.V, and.8v, respectively, appear (Figure ). For the MAXB,.9V,.V, V, and V, respectively, appear. 8) Confirm with the ammeter that the quiescent current is approximately µa. Then, in the Global Resources tab on the GUI, set the Main Bias Low Power Mode bit to and click the Write button. Now, confirm that the quiescent current is approximately µa. Note that the MAX will have an extra µa current when J and J are installed. See the MAX/MAX EV Kit Differences section for more information. This concludes the Quick Start procedure. Users are now encouraged to explore the device and its register settings with the GUI. For guidance on configuring the charger and the LED s, see the Charger Quick Start and LED Quick Start sections. During general device evaluation, set the ammeter range to greater than or equal to A to minimize the impact of its series resistance. For more information on the GUI, see the Software section.

8 MAX/MAX Evaluation Kit Evaluates: MAX/MAX EV Kit Features On-Key Options For applications that require the IC to enable with a userinteractable switch, the EV kit comes with two common types: the push-button (momentary) and the slide-switch (persistent). The active-low enable pin (nen) has an external pullup resistor R. Select which type of switch to use with jumper J. Refer to the MAX/MAX data sheet for more information on configuring the IC for momentary or persistent switches. Temperature Monitoring Jumper J allows selection between the following temperature monitoring options: ) Potentiometer R (Connect pins and ) ) Fixed resistor divider R (Connect pins and ) ) 8K negative temperature coefficient thermistor (NTC) RT (Connect pins and ) Use the potentiometer setting (pin and ) to simulate changing temperature to evaluate the charger s JEITA safe charging response. Turn the potentiometer knob counterclockwise to simulate increasing battery temperature. Turn the knob clockwise to simulate decreasing temperature. Use the resistor setting (pin and ) to set a static temperature ( C). Use the thermistor setting (pin and ) to evaluate the charger s response to actual EVK temperature. The NTC beta parameter is 8K. Temperature thresholds corresponding to this NTC beta are listed in Table. The MAX/MAX automatically biases the temperature monitoring circuit whenever CHG is valid and the thermistor is enabled (THM_EN = ), or the MUX_SEL[:] bitfield is connecting the THM or TBIAS pins to the AMUX output (MUX_SEL = b or b). Refer to the Adjustable Thermistor Temperature Monitors section of the MAX/MAX data sheet for more information. Table. Trip Thresholds for 8K Beta Thermistor TRIP VOLTAGE (V) TRIP TEMPERATURES ( C) Battery Ammeter The EV kit comes with an on-board ammeter for users to measure battery current with selectable ma or ma range. The battery current sense resistor voltage is amplified with an op-amp and then converted with an ADC. The GUI reads the ADC value and displays the corresponding current measurement. There is a removable jumper J8 (default installed, near the Li+ battery connector J9) that shorts the negative terminal of the battery to. To use the on-board battery ammeter, remove jumper J8 and select the desirable ammeter range (ma or ma) in the AMUX/ADC tab of the GUI. Reinstall jumper J8 when not using the on-board battery ammeter. See the Software section for where to read the current value on the GUI. Maxim Integrated 8

9 MAX/MAX Evaluation Kit Evaluates: MAX/MAX Electronic Load The EV kit comes with an electronic load that allows the user to easily evaluate the SIMO and LDO. An on-board DAC and op-amp configuration set the load current through IC. J, J, J, and J connect the load to the output of the SBB, SBB, SBB, and LDO, respectively. Emulate SYS loading by removing J and connecting pin of the header to VSYS with a wire. To exercise the load transient response, remove J (for SBB), J (for SBB), J (for SBB), or J (for LDO) and connect a signal generator to the gate of the load MOSFET (pin of the header). Drive the MOSFET gate with a signal between V (off) and V (fully on) to apply transients to the output of the SIMO or LDO. Note that there is a Ω sense resistor that has test point access (called VIL_SBB, VIL_SBB, VIL_SBB, and VIL_LDO) that allows for a : conversion of load current to voltage. See the Software section for how to set the load current from the GUI. On-Board ADC (MAX) An on-board ADC is available to convert the output voltages of SBB, SBB, SBB, and LDO. The AMUX pin of the MAX/MAX, test points A and A, and battery current (IBATT) are also measured. The GUI does the appropriate conversions. See the Software section for how to read these values from the GUI. Software The graphical user interface (GUI) software allows for quick, easy, and thorough evaluation of the MAX/ MAX. The GUI is designed to have individual tabs for each functional block of the device (global resources, interrupts/status, GPIO, charger, SIMO buck-boost, LDO, and LED driver) and two additional tabs for controlling EV kit hardware (load control and AMUX/ADC). See Figure 8 for a screenshot of the GUI upon first opening.

MAX/MAX Evaluation Kit GUI Top-Level Interface Installation Visit the product webpage at com/maxevkit and navigate to Design Resources to download the latest version of the EV kit software. Save the EV kit software to a temporary folder and decompress the ZIP file. Windows Drivers Upon connection of a Micro-USB cable between your PC and the EV kit for the first time, wait a few minutes for Windows to automatically install the necessary drivers. Graphical User Interface Details (GUI) The GUI drives IC communication with the EV kit. Every control in the GUI (excluding the Load Control and AMUX/ADC tabs) corresponds directly to a register within the MAX/MAX. Refer to the Programmer s Guide and IC data sheet for a complete description of the registers. The Load Control and AMUX/ADC tabs provide additional functionality with the EV kit. Load Control Tab The Load Control tab contains controls for setting loads on the regulator outputs. The GUI is capable of setting steady-state, transient, and random load currents. To set a load current, use the slider bar or text field to input a value (ma) and click the Enable button. Shuffle through the modes to exercise different load conditions. The offset and gain values are set by Maxim and do not need to be altered. AMUX/ADC Tab The AMUX/ADC tab allows users to convert important voltage and current signals to digital readings. To read a signal, click the Read button and examine the Interpreted Value column. Maxim Integrated

11 MAX/MAX Evaluation Kit Evaluates: MAX/MAX Charger Quick Start The Charger tab on the GUI has many settings to toggle; however, only three registers are needed to charge a battery. To get started with the charger, follow the procedure below: ) Determine the capacity of the battery to identify a safe charge current. Maxim recommends charging at % of the total capacity (e.g., a mah battery can be charged at ma charge current). Consult the battery manufacturer s data sheet carefully to determine safe charging parameters. ) In Charger Configuration E/F, move the Fast-Charge Current (IFAST_CHG) slider to the desired charge current setting, and click the Write button. ) In Charger Configuration G/H/I, move the Fast- Charge Voltage (VFAST_CHG) slider to the desired charge voltage setting, and click the Write button. ) Make sure there is a charge source connected to the EV kit at V. Then, enable the charger by setting the button labeled Charger to (Enabled) and click the Write button. ) The battery should now be charging at the charge current set from step. For more information on the capabilities of the battery charger, refer to the IC data sheet and Programmer s Guide. LED Quick Start There is an RGB LED cluster on the EV kit, and three current sinks (LED, LED, and LED). To get started with the EV kit LEDs, follow the procedure below: ) Choose an LED Configuration section to change. LED controls Blue, LED controls Red, and LED controls Green. ) The main-bias circuits must be on for the current sinks to enable. This can be accomplished by: pressing the on-key (SW), or in the Global Resources tab of the GUI, setting the Main Bias Enable Controller bit to a and click the Write button. Pressing the on-key will allow the internal on/off controller to enable the main-bias, while setting the GUI bit to will force the main-bias circuits on. ) On the LED Driver tab of the GUI, set the desired LED Full Scale to.ma. ) Set the Duty Cycle and Period to a desired blinking configuration (% duty cycle for always-on). ) Set the Brightness to % or adjust as needed. Click the Write button. ) Set the LED Master Enable bit in LED TOP Configuration to. Click the Write button. The LEDs should now be powered. If they are not, see step of this procedure. ) Adjust the settings for the other LEDs as desired. MAX/MAX EV Kit Differences The MAX and the MAX are the same in every way except for the output voltage range of two of the SIMO outputs. The MAX SBB output voltage range is from.8v to.8v, whereas the MAX SBB output voltage range is from.v to.v. The MAX SBB output voltage range is from.8v to.9v, whereas the MAX SBB output voltage range is from.v to.v. To expedite evaluation of these two products, Maxim offers the MAXEVKIT# and the MAXEVKIT#. Like the devices themselves, these two EV kits are almost identical. The PCB layout and schematic are identical for both EV kits. The silkscreen designator for the part number on the PCB is different as well as the actual device (U). As shown in the MAX/MAX EV Kit Component List, R, R, R, and R are different for each EV kit. On the MAX EV kit, these resistors scale the SBB/SBB output voltages to be within the.9v full-scale range of the MAX ADC. They also create a MΩ impedance path to ground, which creates additional current. To see the true quiescent current of the device, remove J and J from the EV kit. The GUI automatically detects the device version by reading the DIDM bit. The transfer function for converting the SBB and SBB voltages are adjusted based on the version detected. Note that the photos and layout files shown are for the MAX, but are directly applicable to the MAX.
