About this Solution:

Azoteq TechnologySensors & Sensing


The Azoteq ProxSense® capacitive controllers are the most sensitive and robust proximity and touch controllers available today.

  • ProxSense® unique technical features:
    • 1000 x more sensitive than competition (allows proximity)
    • Ultra low power consumption (down to sub 2µA)
    • RF Immunity
    • Water Immunity
    • Touch on Metal options
    • RF noise detection
    • Automatic Tuning Implementation
    • AC Noise filtering
    • On-chip regulator
    • Integration of external componentsr
    • Lowest system cost


Azoteq's ProxFusion™ sensor family builds on more than a decade of capacitive sensor experience to integrate more than 6 different sensor technologies into a single IC:

  • Capacitive
  • Inductive
  • Hall-effect switch
  • Hall rotation sensor
  • IR
  • Support for PIR (external component)
  • Ambient light sensors
  • All combined into single package
  • The single package, multi-sensor approach ensures:
    • Smaller BOM
    • Lower cost
    • Lower power consumption
    • Water Immunity
    • Higher reliability
    • Less overhead on the host MCU

Low Voltage and High Voltage LED Drivers


Azoteq's LightSense™ product range of intelligent switches, offers a sophisticated and cost-effective alternative to electro-mechanical switches. Applications include flashlights, headlamps, child lights, automotive interior lights, seat warmers and battery-operated toothbrushes. LightSense™ is widely used by the leading manufacturers of flashlights and headlamps.

  • Advanced Features:
    • Automatic switch-off (time-based)
    • Brightness selection
    • Strobe functions
    • Continuous find-in-the-dark
    • Battery Power Meter
    • Constant Illumination
    • Temperature control
    • Customizable user interface
    • Modes: High, Medium and Low Power, Fast Flash, Slow Flash and SOS


Azoteq's PowerSense™ family provides reliable and cost effective solutions to the high voltage LED lighting industry. Solutions are based around Azoteq’s proprietary high voltage driver family. Azoteq supplies driver IC’s, modules and fully assembled bulbs, tubes, luminaires, high-bay lights and spotlights to a worldwide customer base.
