The EVM is a combination of a motherboard and daughterboard. The motherboard includes a TLC555 timer configured to supply a PWM to the DRV10963 and a potentiometer to adjust the speed of the motor by varying the duty cycle of the PWM and has USB2ANY connector to communicate with DRV10963 GUI. The daughterboard contains a socket allowing the device to be programmed using the DRV10963 GUI via I2C communication and it is mounted on top motherboard, as shown in Figure 1. The EVM set-up, together with DRV10963 GUI also provides means to program OTP (one time programmable) of DRV10963 blank version (un-programmed OTP) device for any custom motor solution. The DRV10963 GUI is easy to use, requires only four simple steps to tune the motor for any end application and program the device OTP. The DRV10963 EVM comes with blank version device with unprogrammed OTP bits. The DRV10963 device has configurable shadow registers corresponding to each OTP bit. Shadow registers provide ease-of-tuning to the user, as their values can be changed indefinitely during the course of tuning to arrive at the best optimized values. The DRV10963 also has an I2C interface, this allows the user to program specific motor parameters in shadow registers, before deciding on final values to program OTP. Note that configurable shadow registers are volatile and lose their values in power off condition. This document describes the kit details and explains the functions and locations of test points, jumpers, and connectors present on the kit. This document is also a quick start guide for using the GUI to tune a motor for an end application. For detailed information about the DRV10963, refer to the DRV10963 data sheet (SLAS955A). Figure 1.

The DRV10963 EVM is provided with a GUI to configure the device and tune the application. Refer to DRV10963_2P0 User Manual.pdf present (C:\Program Files (x86)\Texas Instruments\DRV10963_2P0 EVM\Documents) in the GUI-installed directory for instructions to download and install the GUI application. Create a desktop shortcut with the name DRV10963_2P0 EVM, for future use. 2. Install the Run-Time Engine LabVIEW-2014 from the following link, for complete instructions, refer to http://www.ni.com/download/labview-run-time-engine-2014/4887/en CAUTION Do not apply power to board before you have verified settings mentioned in Section 5.2 and Section 5.3! 5.2 Initial Hardware Settings The kit ships with the daughterboard already mounted on top of the motherboard. The daughter socket board also has a pre-inserted DRV0963 blank version device, however, ensure: • The daughterboard is rigidly inserted on the motherboard without any loose connection. Check the orientation of the daughterboard with VCC_IN test-point connected to the right corner. Refer to Figure 2 for details and read instructions written on the motherboard for proper orientation. • The DRV10963 device is properly inserted with right orientation at the socket in the daughter card as per Figure 3, referred to as U1. : VCC_IN Test Point of Daughter-Board Figure 2. DRV10963 Daughterboard Mounting on Motherboard 6 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Quick Start Guide www.ti.com Figure 3. DRV10963 Orientation Inside Daughterboard Socket 5.3 Jumpers and Switch Setup Settings On the daughterboard: 1. Make sure that only jumper J1 is populated, jumper J2 and J3 all 3-pins shall be open On motherboard: 1. Make sure that all jumpers J1, J2, and J3 are populated 2. Switch S1 should be in the off position and switch S2 in the I2C-GUI position. DRV10963 PWM input pin has dual functionality, that is, it serves as speed control input as well as clock signal for I2C. Switch S2 provides a means to configure the PWM input pin for speed control or I2C clock. 5.4 Powering-Up EVM DRV10963 EVM requires two power supply sources, that is, 5 V and 6.2 V to work with the GUI to enable I2C interface for register configuration. Note that programmed device needs only one 5-V supply in the final end-application circuit. Use the following sequence to power-up the EVM and to establish a successful connection with the GUI: 1. Do not power up the power supply. First, connect the power supply ground to pin GND, the 6.2 V to pin V_Testmode, and 5 V to PowerIn on the motherboard at connector P3. At this point, make sure that switch S1 is in the turn-off position and the “USB2Any” board is not connected to the motherboard. If using a lab power supply, it is recommended to set the current limit of both power supplies to 1.5 A. 2. Turn the POT-R17 fully CCW (counter-clock wise). This keeps the speed PWM input to the minimum value. 3. Connect the 3-phase terminal of motor to connector P4 on the daughterboard. It is not important to observe the polarity as it only determines the direction of rotation. 4. Now power up the board and turn switch S1 to the “on” position. Check LED1, LED2, and LED3. All should turn green. 5. Connect USB2Any box first, via the supplied USB cable to the computer. Then connect the 10-pin ribbon cable to the USB2ANY connector on the motherboard.

Now launch the DRV10963EVM GUI by double clicking the DRV10963_2P0 EVM shortcut on the desktop. If "Demo Mode" is selected, the screen shown in Figure 4 appears, deselect "Demo Mode" to go to the next step. Figure 4. GUI Initial Screen With Demo Mode 2. If "Demo Mode" is not select previously, the screen shown in Figure 5 appears as soon as the GUI launches. The "CONNECTED" block should turn green indicating that the GUI is successfully connected to USB2ANY. 8 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Quick Start Guide www.ti.com Figure 5. GUI Screen With Successful I2C Interface 3. Left-click on the step 1 button “Set Default Resister Values”. Step 1 is always mandatory before proceeding to step 2 to enable configuration of the device. This step programs the following parameters to the corresponding shadow register, as shown in Figure 6. These default values correspond to the factory programmed part DRV10963JJ. Refer to the DRV10963 datasheet for a detailed explanation of different versions of DRV10963 and descriptions of tunable parameters. • "Start Up Align Time" - 350 ms and "Start-up Acceleration Rate" - 80 Hz/s • "Open to Close Loop Threshold" - 100 Hz • "PWM Duty Cycle Cutoff" - 10% • "FG Frequency Divider" - 1 or 1/3 • "Software Current limit" - 500 mA • "Voltage Delay" - 120 µs To enable motor spin with the above parameters, open the jumper J1 on the motherboard. There is a high probability that the motor will start rotating with previously shown default values. This state is equivalent to driving the motor at maximum speed with 100% duty cycle because PWM input being connected to the I2C clock input continues to receive a high signal. Ensure that the parameters previously shown are optimized for their end application. Refer to Section 6 for guidelines to optimally determine and tune motor parameters using the GUI.

Default Configuration Parameters 4. To facilitate the tuning at different speeds or across a speed range, the EVM provides a TLC555 timerbased PWM generation circuit and potentiometer (R17) to adjust the duty cycle of PWM to control the speed of the motor. To enable speed control via POT-R17, change the switch S2 position to PWM Speed Control mode. Turn the POT-R17 clock-wise to increase the motor speed and counterclockwise to reduce it. 5. In case motor performance is not satisfactory with default values or further optimization is desired, try three other factory-programmed device options before attempting to customize parameters. This would benefit in production phase because all versions of factory programmed devices can be easily procured and used directly without the burden to programming the OTP values. The GUI comes with three .txt files corresponding to the three remaining factory-programmed devices. 6. To test motor performance with the DRV10963JM version, short the jumper J1 back. This will stop the motor. Referring to Figure 7, left-click the “Load Config“ button, browse to the GUI installation directory for 3 .txt files in your PC and select DRV10963JM.txt.This will load the register with configuration parameters corresponding to DRV10963JM. Refer to Figure 8 to check configuration parameters corresponding to the DRV10963JM version. In same way, load and configure other versions of DRV10963 to test the performance. To enable motor spin, open the jumper J1 on the motherboard and use POT R-17 for speed control. 10 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Quick Start Guide www.ti.com Figure 7.

DRV10963JM Configuration Parameter 7. After trying DRV10963JM, the next file to load is the DRV10963JU configuration followed by loading the DRV10963JA. 8. If only one of the preloaded configurations spins the motor, then obviously that is the part number to order to control the motor. However, if two or more spin the motor, then refer to Figure 9. Figure 9. Initial Tuning Flow Chart 12 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Tuning Guide www.ti.com 9. Even if one of the four factory-programmed settings do spin the motor, it may not be optimized for that motor. Using whichever DRV10963xx file as a starting point, then run through the tuning guide in Section 6 to create the best settings. However, for convenience it would be easier to just order a factory-programmed part. The "Control Advance Angle Method is described in Section 6.1.6. 6 Tuning Guide If all four of the given factory-programmed settings have been tried (3 .txt files and the default values) and the motor still will not spin or you would like to further optimize your motor then you can try the following steps to custom tune the DRV10963 for your motor. 6.1 Configuring the Device Leave the device connected to the motor and the computer. Next, make sure that the DRV10963EVM is powered up in test mode and the GUI is open. If an error message like the one in Figure 10 is returned, just close the GUI and reopen it and make sure that it reconnects to the device. Figure 10. Error Message Each one of the parameters that you can configure with the GUI will change how your motor reacts to the DRV10963 device. Read the description of each one of the parameters below and then choose if you would like to make the changes suggested. Be sure to connect a current probe to phase V to observe the phase current during tuning. 6.1.1 Start UP Align Time and Start Up Acceleration Rate Start-up align time and acceleration rate determines how fast the motor can reach a particular set speed from standstill, so these values should be chosen to get the fastest possible start-up time. Note that too aggressive values of acceleration rate can cause higher inrush current in starting and may hit overcurrent protection, in which case the motor may not be able to start successfully. It is better to start with slower values and gradually increases to get the fastest possible start-up time based on the application. In the DRV10963 device, both the values are dependent on each other. They can only be configured as a dependent pair. The values tunable from the GUI of align time is in ms and acceleration rate is in Hz/sec. Using the motor inertia from the motor parameters previously determined, estimate the align time. If you do not know, just input the highest possible align time which will correspond to the lowest possible acceleration rate. Then, after tuning the rest of the parameters is complete, come back to align time and step it down one-by-one until the fan will not spin. Then you know the best align time is the value just before the one where the fan stopped.

Correct Align Time and Acceleration Rate Figure 12. Align Time Too Long 6.1.2 Figure 13. Align Time Too Short Open to Close Loop Threshold Open to close loop threshold determines the threshold frequency at which the controller goes from openloop commutation to closed-loop, back-emf, zero-crossing-based commutation. For best performance to get stability during dynamic load/speed changing conditions and for maximum possible speed range, the motor should run in closed-loop commutation mode, therefore, the threshold frequency should be chosen as low as possible. However, too low values will cause an issue with sensor-less control because backemf will not be sufficient to allow closed loop operation. Typically this threshold should be 10% to 25% of the speed desired to run the motor. The values tunable via GUI are in units of Hz. Normally, higher-speed motors (maximum speed) require a higher handoff threshold because higher speed motors have lower Kt, and as a result, lower BEMF. In other words, if your desired RPM is 3000, then the open to close loop threshold should be 1/4 × (500 rpm) = 125 Hz. Therefore, the open to close loop threshold should be around 50≈125 Hz. 14 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Tuning Guide www.ti.com Figure 14. Open to Close Loop Threshold Too Low 6.1.3 Figure 15. Open to Close Loop Threshold Too High PWM Duty Cycle Cutoff PWM duty cycle cutoff decides the minimum operating duty cycle; this can be chosen to meet minimum speed requirements. Refer to the DRV10963 datasheet for more information about the different minimum duty cycles. 6.1.4 FG Frequency Divider The FG pin provides an indication of the speed of the motor. There are two options, 1 or 1/2 toggles FG once every 2 electrical cycles and 1 or 1/3, toggles FG once every 3 electrical cycles. This signal can be used to get the motor speed feedback information. In order to see this relationship off of the FG pin on the daughterboard, the device must be taken out of test mode by opening the jumper J1 on the motherboard, using the POT R-17 for speed control, and the FGS pin must be driven low. For more information about this, refer to the DRV10963 datasheet. 6.1.5 Software Current Limit The software current limit function is only available in closed loop commutation mode. It works more like an active current or better as torque limit, and does not cause overcurrent trip. This value can tune to get a particular speed at a given motor loading condition. For example, increasing its value increases the motor-applied torque and thus the speed, however, ensure that the value is not exuberantly high to prevent motor heating. A lower value will prevent the motor from reaching a higher speed. Start out at 0.125 A to make sure that your motor will spin and then slowly start to increase the current limit until it fails, then use the current limit right before. Figure 16. Current Limit Too High Figure 17. Current Limit Very Small SLAU643 – July 2015 Submit Documentation Feedback DRV10963 Evaluation Module Copyright © 2015, Texas Instruments Incorporated 15 Tuning Guide 6.1.6 www.ti.com Control Advance Angle Method a.k.a Voltage Delay Voltage delay represents lagging phase angle (in unit of time) of back-emf with respect to applied voltage. As explained in the datasheet, for efficient operation, applied voltage must lead the back-emf to force the motor-current in phase with back-emf for constant air-gap BLDC moor without saliency. For salient pole motors back-emf and phase current may have phase angle difference for efficient operation depending upon motor parameters. Both types of motor can be tuned efficiently via the GUI using voltage delay. In the GUI, zero delay setting forces the applied voltage in phase with back-emf and increasing its value, make the applied voltage to lead with respect to back-emf. To determine the optimized value, run the motor at rated speed as per end-application requirement and adjust the value to draw minimum current from the power supply. 1. Configure the motor using the Tuning Guide up to this point and make sure it can spin in closed loop control (after the current flat lines on startup and then keeps oscillating). Switch S2 to the PWM so it can receive a PWM signal. Have a current probe on one of the phases of the motor and a voltage probe on the FG pin of the daughterboard. Also make sure that the input voltage VIN is run through a multimeter so that you can know the exact output current at all times. 2. Change the Voltage Delay to “No Delay” and click ‘Configure Parameters’. 3. Next, the device must be taken out of test mode. Disconnect the USB2ANY from the EVM board. Turn off the output of 6.2 V. Disconnect the J2 jumper from the motherboard. 4. Connect a function generator to the PWM in the pin located on the daughterboard. The function generator is outputting 50 kHz square wave at 5 Vpp with 2.5 V DC offset and in High Z. Using this signal, adjust the duty cycle to reach the RPM that is desired for your application. The RPM can be obtained using Equation 1. The frequency of the FG pin corresponds to the electrical frequency. ƒ elec RPM = ´ 60 # of poles (1) 5. Take the current measure from the multimeter. 6. Once you have those taken down, turn off the output of the function generator and do the steps in reverse order to put the device back into test mode. Connect J2 and the USB2ANY and then turn on the 6.2-V supply. 7. Reopen the GUI, connect to the device and set the default register values like in the tuning guide. Next, configure all other values to what they were when the motor was spinning in closed loop. 8. Repeat Steps 2-7 several times changing the "Voltage Delay" each time to get a few reference points. 9. The "Voltage Delay" value that has the smallest current off of the multimeter is the current that is most in phase with the BEMF. If you are deciding between the JA and the JJ models, just do Steps 4 and 5 for both parts and pick the one with the minimum current between the two. 6.2 Writing to the OTP Registers Each time when writing to the OTP registers, always ensure: Jumper J1 on motherboard remains: Shorted to enable I2C and configuration via GUI Open to enable motor spin after any configuration Switch S2 on motherboard remains: I2C-GUI to enable I2C and configuration via GUI "Speed Control" mode to enable PWM to device 1. The EVM provides means to program the OTPs of a blank part. To enable OTP programming of any new blank device: • Disconnect the motor from EVM • Start with initial condition of jumpers/switches mentioned in Section 5.3 and follow-up power on EVM steps of Section 5.4. 2. As a first step to program the OTP, launch the GUI and left click "Set Default Register Value", that is, step 1. Load the custom configuration as shown in Figure 18 from the stored directory on your PC. 16 DRV10963 Evaluation Module SLAU643 – July 2015 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Tuning Guide www.ti.com Figure 18. Load Custom Configurations to GUI 3. Increase the V_Testmode voltage level to 7.4 V and Vpower_in to 6.2 V. Now, left click “Write OTP Values” from the GUI. This will program the OTP bits of a blank device with user-configured values. CAUTION Never exceed Vpower_in beyond 6.5 V in any circumstances to prevent damaging the EVM. 4. In order to ensure that OTP are programmed properly, step 4 provides a means for read-back option. To enable read-back, first reduce the V_Testmode voltage level back to 6.2 V and Vpower_in to 5.0 V and left click “Read OTP Values”. If the GUI does not give any error message, it ensures the correct OTP programming. This means the device is ready to be used in stand-alone mode at the endapplication circuit. 5. The final test to ensure proper OTP programming, power down both power supplies, disconnect the USB2ANY. Reconnect the motor to EVM and reapply 6.2 V and 5.0 V, don’t connect USB2ANY and open the jumper J1 on motherboard. The motor will start rotating confirming that the OTP are programmed and device is ready to use. NOTE: The DRV10963 blank version is not available off-the-shelf for direct purchase, contact TI sales or distributors for further details if custom settings for production with a blank version is desired.

The following sections details several common issues that could happen and how to fix them. 6.4.1 Hitting Current Limit If the beginning of the current waveform looks like Figure 19, there might be a problem with the current limitation of the chip itself. If the align time is small, the current limit of the chip is reached and the chip turns itself off, waits for a set amount of time then tries again. If you see a waveform like the one below either add a 1-Ω resistor to each one of the 3 phases or lower the VIN to around 4.8 V. Figure 19. Motor Hitting Current Limit and Trying Again 6.4.2 Open to Close Loop Threshold High Sometimes even though the motor will go into closed loop at a certain threshold does not mean that it is optimized. If the current waveform resembles the one shown in Figure 20 before it goes into closed loop (it goes into closed loop after the flat line in the middle where the GUI is measuring the BEMF) then it means that the Open to Closed Loop Threshold is high. This is an inefficient way to start up the motor because it is dangerously close to hitting a current limit and stopping the motor waiting and trying again. The optimized performance would be to make the current funnel down until it hits closed loop control. Figure 20.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
