DRV2603 www.ti.com SLOS754C–JUNE2012–REVISEDAUGUST2016 8 Detailed Description 8.1 Overview The DRV2603 is a haptic and vibratory driver designed specifically to meet the needs of haptic and vibration applicationsintheportablemarket.TheDRV2603hastwomodesofoperation,ERMmodeandLRAmode.ERM mode is designed to drive Eccentric Rotating Mass motors, which are generally DC motors of the bar or coin type. LRA mode is designed to drive Linear Resonance Actuators, also known as linear vibrators, which require an alternating signal that commutates at or very near the natural mechanical resonance frequency of the actuator. These actuators present a unique control challenge that is solved in the DRV2603 by auto resonance tracking. 8.2 Functional Block Diagram VDD VDD Thermal Supply Correction Shutdown OUT+ C VDD Overcurrent Gate Shutdown Drive EN LRA Control Engine Back-EMF M or LRA / ERM Detection ERM VDD OUT- PWM Gate Drive Level Correction GND Copyright © 2016, Texas Instruments Incorporated 8.3 Feature Description 8.3.1 SupplyVoltageRejectionforConstantVibrationStrength The DRV2603 features power supply feedback, so no external supply regulation is required. If the supply voltage drifts over time (due to battery discharge, for example), the vibration strength will remain the same so long as thereisenoughsupplyvoltagetosustaintherequiredoutputvoltage.The DRV2603canbeconnecteddirectlyto thebattery. 8.3.2 Low-VoltageControlLogicforConstantVibrationStrength The PWM input uses a digital level-shifter, so as long as the input voltage meets the V and V levels, the IH IL vibration strength will remain the same even if the digital levels were to vary. These benefits apply to both ERM modeandLRAmode. 8.3.3 ThermalProtection The DRV2603 has thermal protection that will shut down the device to prevent internal overheating.

DRV2603 SLOS754C–JUNE2012–REVISEDAUGUST2016 www.ti.com Feature Description (continued) 8.3.4 OvercurrentProtection The DRV2603 has overcurrent protection that is useful in preventing damage from short conditions. The overcurrent protection monitors current from VDD, GND, OUT+, and OUT-. See the Specifications for typical overcurrentthresholds. 8.3.5 LinearResonanceActuators(LRA) Linear Resonant Actuators, or LRAs, only vibrate effectively at their resonant frequency. LRAs have a high-Q frequency response due to which there is a rapid drop in vibration performance at offsets of 2 to 3 Hz from the resonant frequency. Many factors also cause a shift or drift in the resonant frequency of the actuator such as temperature, aging, the mass the product to which the LRA is mounted, and in the case of a portable product, the manner in which it is held. Furthermore, as the actuator is driven to its maximum allowed voltage, many LRAs will shift several Hz in frequency due to mechanical compression. All of these factors make a real-time trackingauto-resonantalgorithmcriticalwhendrivingLRAtoachieveconsistent,optimizedperformance. g n - o ati r e el c c A Frequency - Hz f RESONANCE Figure9. TypicalLRAResponse 8.3.6 AutoResonanceEngineforLRA No frequency calibration or actuator training is required to use the DRV2603. The DRV2603 auto resonance engine tracks the resonant frequency of an LRA in real time. If the resonant frequency shifts in the middle of a waveform for any reason, the engine will track it cycle to cycle. The auto resonance engine accomplishes this by constantly monitoring the back-EMF of the actuator. The DRV2603 tracking range for LRA devices is 140 Hz to 220Hz. 8.3.7 EccentricRotatingMassMotors(ERM) Eccentric Rotating Mass motors, or ERMs, are typically DC-controlled motors of the bar or coin type. ERMs can be driven in the clockwise direction or counter-clockwise depending on the polarity of voltage across its two terminals. Bi-directional drive is made possible in a single-supply system by differential outputs that are capable of sourcing and sinking current. This feature helps eliminate long vibration tails which are undesirable in haptic feedbacksystems.. Figure10.

DRV2603 www.ti.com SLOS754C–JUNE2012–REVISEDAUGUST2016 Feature Description (continued) Another common approach to driving DC motors is the concept of overdrive voltage. To overcome the inertia of the motor's mass, they are often overdriven for a short amount of time before returning to the motor's rated voltage to sustain the motor's rotation. Negative overdrive is also used to stop (or brake) an ERM quickly by reversingthemagneticfieldofthedrivingcoil(s). 8.3.8 EdgeRateControl The DRV2603 output driver implements Edge Rate Control (ERC). This ensures that the rise and fall characteristics of the output drivers do not emit levels of radiation that could interfere with other circuitry common inmobileandportableplatforms.BecauseofERC,nooutputfilterorferritesarenecessary. 8.4 Device Functional Modes 8.4.1 LRAMode When in LRA mode, the DRV2603 employs a simple control scheme that is designed to be compatible with ERM mode signaling. A 100% input duty cycle gives full vibration strength, and a 0% to 50% input duty cycle gives no vibration strength. The auto resonance detection algorithm takes care of the physical layer signaling and commutation required by linear resonance actuators. The DRV2603 implements closed-loop operation comprising a simple feedback loop. If the back-EMF feedback tells the device that the vibration is too low relative to the input duty cycle, the DRV2603 will increase the vibration strength. If the back-EMF feedback tells the device that the vibration is too high relative to the input duty cycle, the DRV2603 automatically enforces a braking algorithm. It follows that a 0% to 50% input duty cycle will always enforce braking until the LRA is no longer moving. This form of signaling is used to preserve the same input format for both ERM and LRA drive; therefore,nosoftwarechangesarerequiredwhenswitchingbetweenERMsandLRAswiththe DRV2603.

LRAMode The exact full-scale output voltage depends on the physical construction of the LRA itself. Some LRA devices give a small amount of back-EMF during full scale vibration, and other LRA devices give a much larger amount. A nominal full-scale output value is 2.2 V , but it can typically vary as much as +/- 10% depending on the RMS actuator's physical design. The output voltage can be approximated by the following equation between 50% and 100%inputdutycycle. éInputDutyCycle% ù VOUT(RMS)=VOUT(FULL-SCALE) ê -1ú ë 50 û (1) Since the DRV2603 includes constant output drive over supply voltage, the output PWM duty cycle will be adjustedsothattherelationshipintheaboveequationwillholdtrueregardlessofthesupplyvoltage.

Most competing solutions require external components for biasing or level-shifting, but the DRV2603 requires only one decoupling capacitor giving a total approximate circuit size of 2 mm by 2 mm.

DRV2603 www.ti.com SLOS754C–JUNE2012–REVISEDAUGUST2016 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The DRV2603 is designed to drive ERM and LRA actuators used for haptic feedback. ERM and LRA actuators can be used for numerous haptic feedback applications including vibration alerts, advanced vibration communication,buttonreplacement,andtactilefeedbackfortouchsurfaceorscreens. The DRV2603 output is controlled using PWM input. The duty-cycle of the PWM determines the amplitude of the output waveform. By varying the duty cycle, advanced haptic patterns and sequences can be created such as click,bumps,pulses,rampsandmanymore. If a PWM port is not available, the DRV2603 PWM pin can be controlled with a GPIO; however, the DRV2603 will only function as an ON-OFF driver. In the case of an ERM, when the GPIO is ON the output is 100% and whentheGPIOisOFFtheoutputis-100%(oppositedirection).InthecaseofanLRA,whentheGPIOisONthe output is 100% and when the GPIO is OFF the driver automatically brakes and will automatically bring the actuatortorest. 9.2 Typical Application The DRV2603 supports both ERM and LRA actuators. The operating mode can be selected by pulling the LRA/ERM pin either HIGH or LOW. Figure 13 shows the LRA configuration and Figure 14 shows the ERM configuration.

Thefollowingcanbeusedtoselecttheminimumrequiredsupplyvoltage. 1. Find the rated and/or maximum operating voltage in the actuator datasheet; some actuator datasheets may onlyhavetheratedvoltagelisted. 2. Using the larger of the rated and maximum operating voltage, add 250mV to get the minimum operating voltage.Adding250mVprovidesoperatingheadroomtoaccountforinternaldriverlosses. 3. Checkthesupplyvoltagetoensurethatthedesiredoutputisachieved. A minimum supply current is also required based on the load. To ensure enough current can be sourced divide the supply voltage above by the load resistance in the actuator datasheet. Compare this number with the current capabilityofthebatteryorvoltagesupply. 9.2.2.2 PowerSupplySelection The DRV2603 supports supply voltages from 2.5 to 5.2V. The DRV2603 can be directly connected to many battery types including common batteries like Lithium-Ion and Lithium-Polymer. The supply rejection feature of theDRV2603eliminatestheneedforavoltageregulatorbetweenthebatteryandVDD. 9.2.2.3 SendingaHapticEffect Sending a haptic effect with the DRV2603 is straightforward. The procedure is the same for both ERM and LRA drive. The ERM/LRA pin should be tied high or low as shown in the system diagrams.
