Touch-Interface Systems Employ Haptic Feedback

With integrated four-wire touch-screen controllers, haptic controller drivers, and infrared-based proximity sensing, the MAX11810 and MAX11811 can drive a DC motor directly or drive piezo elements using an external piezo driver. The MAX11800 and MAX11801 are register-map-compatible versions without haptic controller drivers and proximity sensing. Through simple register programming, the MAX11810/MAX11811 generates greater than 50,000 different haptic patterns with a built-in haptic waveform generator. Programmable registers eliminate the need for a dedicated interface on the application processor or system microcontroller. This programmability simplifies the addition of haptic feedback to any end equipment with a touch screen. These devices are well suited for use in cell phones, MP3 players, portable media players, multifunction printers, card readers, and other industrial equipment. Automotive-qualified part versions exist for use in car GPS, entertainment head units, and rear-seat entertainment systems. Available in high-speed (25 MHz) SPI and fast (400-kHz) I2C versions, all these devices guarantee compatibility with virtually any system or application processor. The MAX11800-MAX11803 are available in 1.6-mm x 2.1-mm, 12-pin TQFN and 12-pin WLP packages. The MAX11810/MAX11811 are available in 2.1-mm x 2.1-mm, 20-pin TQFN and 16-pin WLP packages. Pricing for the devices ranges from $1.26 to $1.81 in 1000-piece quantities. All part versions are available now. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
