Turnkey Multi-Finger Solutions for Robust and Reliable Touchpads and Touchscreens

Don’t compromise on touch performance when designing applications that incorporate a touchpad or touchscreen. Regardless of the conditions, maXTouch touchscreen controllers are designed for robust and reliable operation in challenging environments. They support single-finger, multi-finger and gloved-finger operation for screens up to 24” in diagonal size that are used in a variety of automotive, home appliance, medical and industrial applications.  Host serial I2C, SPI and USB communication interfaces are available across the product portfolio.

maXTouch touchscreen controllers that are designed for automotive applications are AEC-Q100 compliant, fully automotive qualified and are available in Grade 3 (−40 to +85°C) or Grade 2 (−40 to +105°C) variants. Intelligence added to the touch controller enables self- and sensor-diagnostic functions for constantly monitoring the integrity of the touch subsystem. These smart diagnostic features support the Automotive Safety Integrity Level (ASIL) classification index as defined by the ISO 26262 Functional Safety Specification for Passenger Vehicles. Automotive maXTouch touchscreen controllers are the first touch controllers to carry Automotive SPICE Level 3 certification, and they are available in TQFP, LQFP and VQFN packages.

Developing your innovative touchpad or touchscreen application is easy using maXTouch touchscreen controllers. They embed best-in-class and proven touch algorithms to simplify touch system development and significantly reduce time to market. If you need additional assistance, our global technical support team can provide you with answers to your questions.

    • Single-finger gesture such as tap, double-tap or flick
    • Dual-finger gesture such as pinch and rotate

Outstanding Noise Immunity

maXTouch technology has superior Signal-to-Noise Ratio (SNR), which enables you to successfully combat various sources of electromagnetic interference such as:

  • Injected current noise
  • Display radiated noise
  • Backlight and motor radiated noise
  • Fast transient current

maXTouch touchscreen controllers are built on a highly parallel sensing architecture and carry multiple hard-wired analog and digital filters. When combined with a high-performance and low-power CPU core, maXTouch touchscreen controllers maintain a fast reporting rate and excellent touch performance even in the presence of sources of severe electromagnetic noise. All maXTouch touchscreen controllers are designed to meet high Electrostatic Discharge (ESD) requirements, and they have an unmatched track record when used in touch panels that have successfully passed industry-related EMC standards in the automotive, home appliances, medical and industrial markets.
