Texas Instruments announced the introduction of the industry's most highly integrated piezoelectric haptic driver for mobile consumer and industrial designs. The DRV8662 features an integrated 105V boost converter, power diodes, and a 50V to 200V peak-to-peak (Vpp) full-differential amplifier to provide a 50% smaller solution than competing competitive products. In addition, the DRV8662 uses a transformerless, high-efficiency design, which can reduce total solution cost by 40% compared to competing solutions. The DRV8662 has the ability to drive a variety of piezoelectric actuator voltages and supports fast start-ups, providing designers with a great advantage in creating fast, realistic tactile designs.
Steve Anderson, senior vice president of TI's high-performance analog business unit, pointed out: “Realistic tactile feedback effects can significantly enhance the overall user experience of touch-enabled consumer electronics. The high level of integration of the DRV8662 haptic driver can help us to simplify the design by changing the positioning vibration and frequency. Such effects include touch screen input devices or non-touch screen devices, including mobile phones, tablet computers, computer accessories, home appliances, and industrial automation consoles.
