The QT113 charge-transfer (“QT’”) touch sensor is a self-contained digital IC capable of detecting near-proximity or touch. It will
project a proximity sense field through air, via almost any dielectric, like glass, plastic, stone, ceramic, and most kinds of wood. It can
also turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. This capability coupled with
its ability to self calibrate continuously can lead to entirely new product concepts.
It is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a mechanical
switch or button may be found; it 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.
The QT113 requires only a common inexpensive capacitor in order to function.
Power consumption is only 600
μ
A in most applications. In most cases the power supply need only be minimally regulated, for example
by Zener diodes or an inexpensive 3-terminal regulator.
The QT113’s RISC core employs signal processing techniques pioneered by Quantum; these are specifically designed to make the
device survive real-world challenges, such as ‘stuck sensor’ conditions and signal drift. Even sensitivity is digitally determined and
remains constant in the face of large variations in sample capacitor C
S
and electrode C
X
. No external switches, opamps, or other
analog components aside from C
S
are usually required.
The option-selectable toggle mode permits on/off touch control, for example for light switch replacement. The Quantum-pioneered
HeartBeat signal is also included, allowing a host microcontroller to monitor the health of the QT113 continuously if desired. By
using the charge transfer principle, the IC delivers a level of performance clearly superior to older technologies in a highly
cost-effective package.
