Piezo haptic driver enables quick, flexible tactile feedback in consumer and industrial applications
July 21, 2011 // Paul Buckley
Texas Instruments Incorporated is claiming 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.
"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."
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.
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.

A simulation model for the DRV8662 is also available in TINA-TI 9.1, a SPICE-based analog simulation program, at www.ti.com/tina-ti-download-pr.
