DALLAS, July 20, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced the most highly
integrated piezo haptic driver for mobile consumer and industrial
designs. The DRV8662 features an integrated 105-V boost converter,
power diode, and 50-V to 200-V peak-to-peak (Vpp)
fully-differential amplifier, resulting in a solution size that is
50 percent smaller than leading competitors. The DRV8662 also
lowers total solution cost by 40 percent compared to competing
solutions, thanks to an efficient, transformer-less design. With
the capability to drive a wide range of piezo actuator voltages and
fast start-up time, the DRV8662 benefits designers creating fast,
high-definition haptic designs. To order samples and learn more,

"Realistic tactile feedback effects considerably enhance the
overall user experience of touch-enabled consumer electronics
devices," said Steve Anderson,
senior vice president of TI's High Performance Analog business.
"The integration of the DRV8662 haptics driver makes it easy to
include effects like localized vibrations and frequency variations
in both touch screen-input devices and those without a touch
screen, from mobile phones and tablets to computer accessories,
home appliances, and industrial automation consoles."
Key features and benefits
- Piezo modules enable fast start-up time (1.5 milliseconds),
thin form-factor and high bandwidth, resulting in the production of
haptic effects not possible with intertial-based actuators.
- Drives piezo actuator capacitances from 50 to 680 nanofarad
(nF) at 300 Hz, enabling a wide variety of high-resolution haptic
effects, including feedback localized to specific areas of the
device, as well as vibrations and pulses that change in frequency
based on how the user is interacting with the device.
- Transformer-less design and wide supply range of 3.0 to 5.5-V
with direct battery connection reduces solution size and cost.
- Thermal overload protection prevents damage when the device is
overdriven.
Availability and pricing
The DRV8662 is available now in a 4-mm x 4-mm x 0.9-mm QFN
package, priced at $1.75 in
quantities of 1,000.
Tools and support
An evaluation module is available for the DRV8662, priced at
$100, and includes a
fully-programmable MSP430G2553, as well as analog and digital
interfaces for complete standalone and in-system evaluation. Out of
the box, the MSP430 is programmed with sample haptic waveforms for
immediate evaluation. To view more information, including reference
material and sample code, and to place an order, visit

A simulation model for the DRV8662 is also available in TINA-TI
9.1, a SPICE-based analog simulation program. Download TINA-TI 9.1

OMAP compatibility
The DRV8662 can be used with TI's OMAP™ family of processors in
touch screen-enabled devices, such as handsets. The processing
power of the OMAP devices, coupled with the high-definition haptic
effects enabled by the DRV8662, significantly improve the user
experience.
