LRA actuators typically have a narrow frequency
band over which they have an adequate haptic
response. This frequency window is typically ±2.5 Hz
wide or less, so driving an LRA actuator presents a
challenge. The DRV2603 solves this problem by
employing
auto
resonance
tracking,
which
automatically detects and tracks the optimum
commutation frequency. This means that any input
PWM frequency within the input range (10 kHz to 250
kHz) will automatically produce the correct resonant
output frequency. As an additional benefit, the
DRV2603 implements an optimal braking algorithm to
stop the LRA from ringing out, leaving the user with a
crisp haptic sensation.
For both ERM and LRA actuators, the automatic input
level translation solves issues with low voltage PWM
sources
without
adding
additional
external
components, so if the digital I/O levels vary, the
output voltage does not change. The DRV2603 also
has supply correction that ensures no supply
regulation is required for constant vibration strength,
allowing an efficient, direct-battery connection.

TEST SETUP FOR GRAPHS
With no output filter, the output waveform from the DRV2603 looks similar to Figure 1. The output signal contains
both a high frequency PWM component and a fundamental drive component which causes motion in the
actuator. To measure or observe the fundamental drive component, a low-pass filter must be used to eliminate
the PWM component. The digital filter function on a digital oscilloscope was utilized in the rest of the Typical
Characteristic figures. A 1st order, low-pass filter corner between 1 kHz and 3.5 kHz is recommended.

If a digital oscilloscope with digital filtering is not available, a 1st order, low-pass, RC filter network can be used
instead. Care must be taken not to use a filter impedance that is too low. This can interfere with the back-EMF
behavior of the actuator and corrupt the operation of the auto resonance function. A recommended circuit is

APPLICATION INFORMATION
OPERATION
The DRV2603 is a haptic and vibratory driver designed specifically to meet the needs of haptic and vibration
applications in the portable market. The DRV2603 has two modes of operation, ERM mode and LRA mode. 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.
CONSTANT VIBRATION STRENGTH
The DRV2603 features power supply feedback, so no supply regulation is required, and a direct battery
connection may be used. If the supply voltage drifts over time (due to battery discharge, for example), the
vibration strength will remain the same so long as there is enough supply voltage to sustain the required output
voltage. The DRV2603 PWM input also uses a digital level-shifter, so as long as the input voltage meets the VIH
and VIL levels, the vibration strength will remain the same even if the digital levels were to vary. These benefits
apply to both ERM mode and LRA mode.
LINEAR RESONANCE ACTUATORS
Acceleration - g
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
tracking auto-resonant algorithm critical when driving LRA to achieve consistent, optimized performance.
fRESONANCE
Frequency - Hz
Figure 11. Typical LRA Response
AUTO RESONANCE ENGINE FOR LRA
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
140 Hz.

LRA MODE
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, no software changes are required when switching between ERMs and LRAs with the DRV2603.

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 VRMS, but it can typically vary as much as +/- 10% depending on the
actuator's physical design. The output voltage can be approximated by the following equation between 50% and
100% input duty cycle.

SLOS754A – JUNE 2012 – REVISED JANUARY 2014
ECCENTRIC ROTATING MASS MOTORS (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
feedback systems..
Figure 13. Reversal of Motor Direction
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
reversing the magnetic field of the driving coil(s).
ERM MODE
The DRV2603 is a compact, cost-effective driver solution for ERM motors. 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. This small solution size still comes packed with features such
as a level-shifted input, differential outputs for braking, constant drive strength over supply, edge rate control, and
a wide input PWM frequency range.
When in ERM mode, the DRV2603 employs a simple control scheme. A 100% input duty cycle gives full-strength
forward rotation, a 50% input duty cycle give no rotation strength, and a 0% duty cycle give full-strength reverse
rotation. Forcing the motor velocity towards reverse rotation is used to implement motor braking in ERMs. By
stringing together various duty cycles over varying amounts of time, a haptic motor control signal will be
constructed at the output to precisely drive the motor.

The full-scale, open-load output voltage of the DRV2603 in ERM mode is 3.6V. The output stage has a total
nominal RDS of 1.9 Ω. When driving a 20 Ω ERM at full-scale, the differential voltage seen at the outputs is
approximately 3.3 V. When driving a 10 Ω ERM at full-scale, the output voltage is approximately 3.0 V.
The voltage seen at the outputs as a function of input duty cycle is given by this equation.

EDGE RATE CONTROL
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
in mobile and portable platforms. Because of ERC, no output filter or ferrites are necessary.
DECOUPLING CAPACITOR
The DRV2603 has a switching output stage which pulls transient currents through the VDD pin. A 0.1 µF, low
equivalent-series-resistance (ESR) decoupling capacitor of the X5R or X7R type is recommended for smooth
operation of the output driver and the digital portion of the device.
SENDING A HAPTIC EFFECT
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. Optimum performance is
achieved by using the following steps.
1. At or very near the same time, bring the EN pin high and start sourcing PWM waveform. No delays are
required. The best startup behavior is usually achieved when momentarily overdriving the actuator for 20 ms
to 50 ms. Reference the specifications of the actuator for optimum overdrive characteristics.
2. Change the PWM level as needed to achieve the desired effect.
3. When the effect is complete, set the PWM duty cycle to 0% if braking is desired. The EN pin must remain
high to actively brake the actuator. When braking is complete, set the EN pin low, concluding the haptic
effect. When braking an ERM, the user should take care not to brake the actuator for too long, or counterrotation can occur. When braking an LRA, the auto-resonance engine automatically drives the actuator to
zero vibration, so no significant reverse-phase vibration will ever occur.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. 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.
