The QT110 charge-transfer (“QT’”) sensor IC is a self-contained digital IC used to implement near-proximity or touch sensors. It
projects sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. It can also turn small metal-bearing
objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with an ability to self-calibrate
continuously leads to entirely new product concepts.
The QT110 is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a
mechanical switch or button may be found; they may also be used for some material sensing and control applications provided that
the presence duration of objects does not exceed the recalibration timeout interval.
A piezo element can also be connected to create a feedback click sound.
This IC requires only a common inexpensive capacitor in order to function. Average power consumption is under 20µA in most
applications, allowing battery operation.
The QT110 employs digital signal processing techniques pioneered by Quantum, designed to make it survive real-world challenges,
such as ‘stuck sensor’ conditions and signal drift. Sensitivity is digitally determined for the highest possible stability. No external active
components are required for operation.
The device includes several user-selectable built-in features. One, toggle mode, permits on/off touch control for example for light
switch replacement. Another makes the sensor output a pulse instead of a DC level, which allows the device to 'talk' over the power
rail, permitting a simple 2-wire twisted-pair interface. Quantum’s unique HeartBeat™ signal is also included, allowing a host controller
to continuously monitor sensor health.
By using the charge transfer principle, the QT110 delivers a level of performance clearly superior to older technologies in a highly
cost-effective package.
