Synopsis for Investor:   * Maxim's resistive touch-screen controllers (MAX11810/MAX11811 and     MAX11800/MAX11801) are ideal for mobile phones, MP3 players,     portable media players, digital photo frames, multifunction     printers, point-of-sale and financial terminals, bar     code-scanners, card readers, and industrial equipment.   * Automotive-qualified part versions are available for car GPS,     entertainment head units, and rear-seat entertainment systems.   * Touch-screens are widespread due to their ease of use, intuitive     interface, and stylish look. Resistive touch-screen technology, a     leading touch-screen technology, will remain the volume leader     for the next five years.   * These devices are compatible with virtually any system or     application processor.   * Integrated haptic controller drivers and IR-based proximity     sensing reduce the need for external circuitry, which facilitates     miniaturization of end equipment.   * Digital, on-chip processing automatically validates touch events     which reduces interrupt servicing of false or redundant touch     events and lowers total system power. This capability is crucial     for battery-powered end equipment. 

Designed for applications flexibility, these devices can drive a DC motor directly or 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.

Ideal applications include mobile phones, MP3 players, portable media players, digital photo frames, multifunction printers, point-of-sale and financial terminals, bar code-scanners, card readers, and other industrial equipment. Automotive-qualified part versions exist for use in car GPS, entertainment head units, and rear-seat entertainment systems.

Traditional Haptic Feedback System

The current market solution for haptic feedback using motors requires the application processor/system microcontroller to drive the motor.
