Sunnyvale, Calif.Maxim Integrated Products has introduced the MAX11810 and MAX11811, calling them the first touch-interface systems with integrated 4-wire touch-screen controllers, haptic controller drivers, and infrared-based proximity sensing.
The MAX11810 and MAX11811 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 and MAX11811 generate 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.
Applications include cell 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.
The MAX11810/MAX11811 are available in 2.1mm x 2.1mm, 20-pin TQFN and 16-pin WLP packages.
