    Products Detail

    The QT110 / QT110H is a digital burst mode charge-transfer (QT) sensor designed for touch controls. It projects a sense field through dielectrics like glass, plastic, stone, ceramic, and wood, and can turn small metal-bearing objects into intrinsic sensors. It requires only one external capacitor (10nF to 30nF) for operation and features continuous autocalibration. The device operates from 2.5V to 5V with typical current consumption under 20µA, making it suitable for battery-powered applications. It includes multiple output modes (DC, toggle, pulse), a HeartBeat health indicator, and direct piezo sounder drive for tactile feedback. The IC is designed for human interfaces and can replace mechanical switches in various applications.

    Key Features

    • Less expensive than mechanical switches
    • Projects a touch button through any dielectric
    • Turns small objects into intrinsic touch sensors
    • 100% autocal for life - no adjustments required
    • Only one external part required - a 1¢ capacitor
    • Piezo sounder direct drive for tactile click feedback
    • LED drive for visual feedback
    • 2.5 to 5V 20µA single supply operation
    • Toggle mode for on/off control
    • 10s or 60s auto-recalibration timeout
    • Pulse output mode
    • Gain settings in 3 discrete levels
    • Simple 2-wire operation possible
    • HeartBeat health indicator on output
    • Active Low (QT110), Active High (QT110H) versions
