Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI's Product Information Center http://support/ti./com for further information. Save all warnings and instructions for future reference. Failure to follow warnings and instructions may result in personal injury, property damage, or death due to electrical shock and burn hazards. The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise and knowledge of electrical safety risks in development and application of high voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitable qualified, you should immediately stop from further use of the HV EVM. 1. Work Area Safety (a) Keep work area clean and orderly. (b) Qualified observer(s) must be present anytime circuits are energized. (c) Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access. (d) All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other related apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located within a protected Emergency Power Off EPO protected power strip. (e) Use stable and nonconductive work surface. (f) Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. 2. Electrical Safety As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. (a) De-energize the TI HV EVM and all its inputs, outputs and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely deenergized. (b) With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment connection, and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. (c) After EVM readiness is complete, energize the EVM as intended. WARNING: WHILE THE EVM IS ENERGIZED, NEVER TOUCH THE EVM OR ITS ELECTRICAL CIRCUITS AS THEY COULD BE AT HIGH VOLTAGES CAPABLE OF CAUSING ELECTRICAL SHOCK HAZARD. 3.

Figure 1 shows the names and locations of the various elements on the EVM. To power the board, connect the DRV2700EVM-HV500 to an available USB port on your computer using a mini-B USB cable. The default board settings cause the microcontroller (MSP430) to control the inputs of the DRV2700 at power up. The MSP430 has each of these control settings low which disables the DRV2700, by default. Figure 1 shows the basic board diagram of the DRV2700EVM-HV500.

This EVM allows the designer to evaluate this device and appropriately prototype it into their design. See the DRV2700 (SLOS861) datasheet for more in-depth information. 2.2 Microcontroller (MSP430) An onboard MSP430F5510 is used to control the various input signals as well as communicate through the USB to the GUI. See the Quick Start Board Setup section for how to setup and run with the GUI. 2.3 Power Supply Inputs and Path Two power supply inputs are available to power the EVM: USB power and VEXTERNAL (Ext VIN on the EVM). Each of these inputs can be used to power the entire board or parts of the board. 2.3.1 USB Power Input The USB power input can be supplied from a standard USB port on a computer, USB charger, or USB battery pack. This input is intended for ease-of-use and can be routed to power all circuitry on the EVM. Additionally, this input has a 5-V LED indicator showing that power is being supplied to the EVM. If the GUI is going to be used, the USB must be connected to the computer and JP2 routed to USB connection. 2.3.2 VIN/External Power Input Provide the VIN power input with an external 3.6- to 5.5-V power supply. Additionally, this input can power the entire board. 2.3.3 Power Path Selection VIN External DRV Header USB Power MSP Header Each of the two power supply inputs can be routed to the DRV2700 or the rest of the IC. The positions of the jumpers are described in Table 2 or can be read from the silkscreen of the EVM. Figure 2 shows the basic diagram of the power paths. Power to Rest of Board Power to DRV2700 Figure 2. Power Path Diagram If a power measurement of the DRV2700 circuitry is desired, it is best to provide the MSP jumper (JP2) with USB power and the DRV jumper (JP4) with VIN. With this configuration, measuring the provided voltage and current into VIN gives the power consumption of the DRV2700. 8 DRV2700EVM-HV500 High Voltage Piezo Driver Evaluation Kit Copyright © 2015, Texas Instruments Incorporated SLOU407A – April 2015 – Revised May 2015 Submit Documentation Feedback Overview of EVM www.ti.com 2.4 EN Configuration The EN input for the DRV2700 has 4 different driving configurations: • Driven through the MSP430. This is done by connecting the configuration jumper to the “MSP” state (default). • Pulled to a logic level high through pullup resistor. This is done by connecting the configuration jumper to the “PU” state. • Pulled to a logic level low through internal pulldown resistor. This is done by removing the configuration jumper. • Driven externally. This is done by connecting the external control signal to the center 100-mil header. This signal has an LED to indicate when the signal is at a logic-level high. 2.5 Inputs The analog input (TP1) is used for PWM and analog inputs. See PWM and Analog Inputs, for more information. 2.6 Outputs The DRV2700EVM-HV500 has a high voltage output ranging from 0–500 V. This output is routed to a terminal connector to mitigate the user touching between the high voltage node and GND. Be sure to disable power when connecting and disconnecting the high voltage node. GND High Voltage Output Figure 3. Output Diagram 2.7 TRIG Button The DRV2700EVM-HV500 has a built-in trigger button for user prototyping. If different modes of operation are desired without using the GUI, the MSP430 can be programmed such that the trigger button can cycle through different modes.

The Standard Drive utilizes changing the frequency and duty cycle of the PWM signal and is intended for easy prototyping and evaluating. The WaveBuilder tab is for showcasing the DRV2700 as a proportional controller that can drive a variety of user-created waveforms. On both tabs, the sections are intuitive, however, the following sections are worth describing: • Output Timing: This button has 3 different modes: Continuous, Pulsed, and Single. These modes help with a timed EN signal. • Boost Voltage Percentage: This is the duty cycle of the PWM waveform and after filtered will be a DC value to modulate the output. Note in the scopeshots in Figure 5 through Figure 8, that the PWM signal's duty cycle is inverse to the output. (As duty cycle increases, the output voltage percentage decreases.) This has been taken care of through software so that the slider bar will reelect the true output percentage though. The boost voltage percentage will only have a true "Boost Voltage Percentage" effect during High Frequency/DC Mode. • PWM Input Frequency: This will change the frequency of the PWM signal coming from the microcontroller, which is fed into the input filter: – Low PWM Frequency (< 1 kHz): When below 1 kHz, the PWM signal will hardly be attenuated such that the majority of the PWM signal will propagate through. This will cause the output to try and reflect the PWM signal coming from the microcontroller and the output will try to be a square wave. The AC Mode - Quick Launch frequency button will set the frequency to this range. – Mid PWM Frequency (1 kHz < freq < 20 kHz): When the frequency is set in this range, the PWM signal will be somewhat attenuated and the output will still somewhat reflect a PWM signal. This mode can be used for audio tones, however, the output may not be able to drive to full scale, depending on the load capacitance. – High PWM Frequency (> 20 kHz): As the frequency starts to go higher, the PWM signal will be greatly attenuated. This will cause the PWM signal to appear DC after this filter. This mode can be used to drive the output at a DC level which is set by the Boost Voltage Percentage (that is, duty cycle). The DC Mode - Quick Launch frequency button will set the frequency to 50 kHz, which is in this range. • Time Between Steps (ms): The time between steps on the wavebuilder tab is the time step between points. This is implemented using a series of DC set points occurring at a certain time of the waveform. The output is limited to 200 sample points. • Waveform From Excel/Text: This text box will build a waveform in the graph based on a commaseparated string of integers from 0-100%. It is best practice to have an oscilloscope measure the output to verify how the load is actually being driven, based on the conditions applied.

Mid PWM Frequency VDD = 5 V C(LOAD) = 22 nF VHV = 0 to 500 V Figure 8. Arbitrary Waveform Using Wavebuilder Tab Flyback Converter The DRV2700 device creates a boosted supply rail with an integrated DC-DC converter that can go up to 105 V. The switch-mode power supplies have a few different sources of losses. When boosting to very high voltages, the efficiency begins to degrade because of these losses. The DRV2700 device has a hysteretic boost design to minimize switching losses and therefore increase efficiency. A hysteretic controller is a self-oscillation circuit that regulates the output voltage by keeping the output voltage within a hysteresis window set by a reference voltage regulator and, in this case, the current-limit comparator. Hysteretic converters typically have a larger ripple as a trade-off because of the minimized switching. This ripple is a function of the output capacitor, internal delays, and the hysteresis of the control loop. Before connecting the load, ensure the load is rated for the current boost voltage setting. See Programming the HV Maximum Output Voltage for more information on how to set the boost voltage. 12 DRV2700EVM-HV500 High Voltage Piezo Driver Evaluation Kit Copyright © 2015, Texas Instruments Incorporated SLOU407A – April 2015 – Revised May 2015 Submit Documentation Feedback Flyback Converter www.ti.com 4.1 Programming the HV Maximum Output Voltage The high voltage output (HV) is set through an external network. For ease-of-use of this EVM, two switches (SW3 and SW4) are installed to change RFB1 and CFB2 with ease. For a normal application, switches should not be needed and those values can be set by passives. Additionally, RFB2 is split into two resistors to provide a reference voltage for the pull-down operational amplifier (opamp) that is discussed in Pulldown Network. VHV C(FB1) VFB R (FB2A) Pull down Reference C(FB2) R(FB2B) Filte r O utp ut Figure 9. VHV Feedback Network The HV output voltage is given by: Equation 2 æ VHV = VFB ç 1 + è RFB1 ö æ RFB1 ö ÷-ç ÷ VOP RFB2 ø è RFB2 ø (1) where VFB = 1.30 V and VOP is the VOL of the opamp since it cannot go all the way to ground. TI recommends the sum of the resistance of RFB1 and RFB2 be between 500 kΩ and 1 MΩ. The capacitors are needed in the feedback network to increase the performance at low and high frequencies. Because the charge storage is inversely proportional to the capacitance, use Equation 2 to calculate the values of the capacitors. In general, select a value around 22 pF for CFB1 and size CFB2 accordingly. RFB1 CFB2 = RFB2 CFB1 (2) Refer to Table 3 for the switch setting to change the maximum output voltage. CAUTION Be sure not to hot switch the SW3 and SW4 connection. This should only be switched while the output is disabled or the board is unpowered. Table 3.

The current limit is not a safety mechanism, but the highest value current the inductor will see each cycle. The inductor must be capable of handling this programmed limit during normal operation. The relationship of REXT to ILIM is approximated with Equation 3 where ILIM is the current limit set by REXT, K = 10500, VREF = 1.35 V and RINT = 60 Ω. æ V REXT =   ç K REF è ILIM 4.3 ö ÷ - RINT ø (3) Transformer Selection Transformer selection plays a critical role in the performance of the DRV2700. The range of recommended primary-side inductance values is 3.3 µH to 22 µH. When a larger inductance is chosen, the DRV2700 flyback converter automatically runs at a lower switching frequency and incurs less switching losses; however, the larger inductances may also have a higher equivalent series resistance (ESR), which will increase the parasitic inductor losses. Another factor to consider for transformers is the winding ratio. In general, if a 200-V output is desired then, because the SW node can boost up to 100 V, a transformer of 1:2 (100 V:200 V) is the minimum required winding. However, selecting a slightly higher winding ratio to ensure that the 100 V on the primary side is not surpassed while trying to boost up to the desired voltage is good design practice. The transformer used on this EVM is a 1:10 winding ratio with a primary side inductance of 7 µH. 4.4 HV Capacitor Selection The HV output voltage may be programmed as high as 500 V on this EVM. A capacitor must have a voltage rating equivalent to the boost output voltage or higher. Because the output can be unloaded, a 1nF output capacitor is added to ensure some amount of stability on the output. Additionally, a non-populated landing pad (C6) is provided for additional capacitance, if desired. 14 DRV2700EVM-HV500 High Voltage Piezo Driver Evaluation Kit Copyright © 2015, Texas Instruments Incorporated SLOU407A – April 2015 – Revised May 2015 Submit Documentation Feedback PWM and Analog Inputs www.ti.com 5 PWM and Analog Inputs The flyback configuration on this EVM uses a low-pass (two pole) filtered PWM waveform from the microcontroller or an analog signal from the user. By default, the DRV2700EVM-HV500 uses the MSP430 PWM input mode. This section describes each input mode in detail and the modifications necessary for operation of each. The DRV2700EVM supports two input modes for driving the DRV2700: • PWM input using MSP430: In this mode, the onboard MSP430 generates a PWM waveform that is sent through the low-pass input filter to the DRV2700. • Analog input: An external source supplies an analog waveform to the TP1 header which is sent through the low-pass input filter to the DRV2700. Because the low-pass filter will try to pass the DC components of the signal, the PWM/Analog input's frequency will determine if the filtered signal will still appear AC. • • • Low Frequency/AC Mode (< 1 kHz): When below 1 kHz, the PWM signal will hardly be attenuated such that the majority of the PWM signal will propagate through. This will cause the output to try and reflect the PWM signal coming from the microcontroller and the output will try to be a square wave. Mid Frequency (1 kHz < freq < 20 kHz): When the frequency is set in this range, the PWM signal will be attenuated but it will still somewhat reflect a PWM signal. This mode can be used for audio tones, however the output may not be able to drive to full scale, depending on the load capacitance. High Frequency/DC Mode (> 20 kHz): As the frequency starts to go higher, the PWM signal will be greatly attenuated. This will cause the PWM signal to appear DC after this filter. This mode can be used to drive the output at a DC level which is set by the Boost Voltage Percentage (that is, duty cycle). See the scopeshots in Section 3 for example waveforms. 5.1 PWM Input Using MSP430 MSP430 Low-Pass Filter DRV2700 Figure 10. PWM Signal When using the DRV2700EVM-HV500 in MSP430 PWM input mode, the onboard MSP430 generates a PWM signal that is sent through a low-pass filter to the DRV2700. The DRV2700EVM-HV500 is set up to use this mode by default. Set to the default settings to use this input mode. If specific waveforms (other than those already on the MSP430) are needed, the firmware can be updated. To update the firmware, download Code Composer Studio (or a third-party MSP430 IDE) and connect the DRV2700EVM-HV500 Spy-Bi-Wire to the computer.

Disconnect the MSP430 output pin from the DRV2700 input pins by removing jumper JP1 2. Connect the DRV2700 EN signal: (a) Use the onboard MSP430 and GUI to control the EN pin by connecting JP3 between EN and MSP (b) EN the output all the time by connecting JP3 between PU and EN (c) Use an external control signal by connecting source to the middle header of JP3 3. Connect the analog input signal to TP1 (INPUT). Note, the default input range is from 0–3.3 V (same as PWM signal). Therefore, if a voltage divider is needed, R21 and R2 can be changed accordingly. 4. Enable the power supply 5. Enable the analog input signal (and EN) Figure 11 and Figure 12 show waveforms using an external sine wave.

Therefore, there are several key specifications to consider when choosing a piezo load; such as dimensions, blocking force, and displacement. However, the key electrical specifications from the driver perspective are voltage rating and capacitance. Figure 13 shows the typical instantaneous maximum load current versus output voltage. 600 540 Max Output Voltage [V] 480 420 360 300 240 180 120 60 0 0 1 2 3 4 5 6 7 8 Instantaneous Load Current [mA] 9 10 11 D001 Figure 13. Instantaneous Max Load Current vs Max Output Voltage 6.2 Pulldown Network The pulldown FET and one or more resistors are used to remove the charge on the high-voltage output faster than just simply using the feedback resistors. Because the FET must be driven from a comparator, an NMOS FET must be used. During normal operation, the VDS of the NMOS is subject to any voltage from approximately 0 V when the FET is on, to the output on the flyback configuration (VHV) when the FET is off. Therefore, selecting a FET with a VDS breakdown higher than the maximum VHV is required. Additionally, placing a resistor in series with this FET (on the source side) to limit the current going through the FET is recommended. This resistor can be sized according to the maximum current allowed per the data sheet of the FET, such that when current flows through the resistor, it raises the source voltage and thereby lowers the VGS and shuts the FET off. Using Equation 4 provides a good value of RS where VG is the VOH of the opamp, VGS(th) is the threshold voltage of the FET and IDS(Max) is the maximum current allowed through the FET. As an additional measure, one or more resistors can be placed on the drain and gate side to protect the pulldown FET by minimizing sharp transients that can be coupled to the other terminals of the FET. VG - VGS(th) RS = I DS(Max) (4) Because the output voltage will ripple (based on the load current and cap) the threshold at which the opamp turns on the FET needs to be set effectively. To try and eliminate the need for external references, two references from the basic circuit configuration are used. The REXT voltage at ≈ 1.3 V is regulated internally by the DRV2700; however, it cannot source or sink very much current. Therefore, by connecting this reference to a high impedance input to an opamp, which draws zero current, this reference can be used.

This works, such that when the output is rippling during normal operation, the threshold will not be triggered. However, when the input signal changes so that the output needs to be discharged, the feedback network will be changed so this reference will become higher than VREXT and therefore turn on the output FET.

Depending on the input frequency and input voltage, the filter can be adapted to attenuate any undesired out-of-band content. This section describes the input filter requirements and the various respective configurations. The filter can be modified by the user, however be sure that the 3-dB point is no higher than 5 kHz. See scopeshots in Section 3 for example waveforms. 7.1 First Order Filter In order to attenuate the high frequency PWM signal, a first order filter was used prior to the integrator to attenuate the high-frequency components. This RC network has a 3-dB point around 1.75 kHz. 7.2 Integrator In order to attenuate the PWM signal even further, a non-inverting integrator is used.
