The MAX11810 and MAX11811 from Maxim Integrated Products, Sunnyvale, CA, are touch-interface systems with integrated 4-wire touchscreen controllers, haptic controller drivers, and IR-based proximity sensing. The 1.6 by 2.1 and 2.1 by 2.1 mm devices can drive a DC motor directly or piezo elements using an external piezo driver. Register programming lets the devices generate >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. The MAX11800 and MAX11801 are register-map-compatible versions without haptic controller drivers and proximity sensing.
