The DRV2667 from TI is being touted as the industry’s most highly integrated piezo haptic driver for HD consumer, automotive and industrial touchscreen applications. Features include a digital interface, integrated 15 V to 105 V boost converter, power diode, and 40 V to 200 Vpp fully-differential amplifier. The driver enables the high fidelity HD haptic experience for a range of products, including smartphones, tablets, white goods and automotive central information displays. The integration of digital waveform generation, high-voltage drive, and 2 kB of RAM eliminates the need for external components, and allows the driver to store and instantly recall haptic waveforms. Digital interface and a 2 ms startup enable a faster haptic effect response time, and a more realistic HD tactile experience that closely resembles the feel of specific events, surfaces or effects. The DRV2667EVM can be purchased for $99 and is supplied with user guide, fully programmable MSP430G2553 Value Line microcontroller, piezo actuator, sample waveforms and capacitive touch buttons. The DRV2667 digital driver is available now in a 20-pin, 4 x 4 x .9 mm QFN package for $2.95 each/1,000.
