These digital charge-transfer (“QT”) QMatrix ICs are designed to detect human touch on up to 16 or 24 keys when used with a
scanned, passive X-Y matrix. They will project touch keys through almost any dielectric, e.g. glass, plastic, stone, ceramic, and even
wood, up to thicknesses of 5 cm or more. The touch areas are defined as simple 2-part interdigitated electrodes of conductive material,
like copper or screened silver or carbon deposited on the rear of a control panel. Key sizes, shapes and placement are almost entirely
arbitrary; sizes and shapes of keys can be mixed within a single panel of keys and can vary by a factor of 20:1 in surface area. The
sensitivity of each key can be set individually via simple functions over the serial port by a host microcontroller. Key setups are stored
in an onboard eeprom and do not need to be reloaded with each powerup.
These devices are designed specifically for appliances, electronic kiosks, security panels, portable instruments, machine tools, or
similar products that are subject to environmental influences or even vandalism. They permit the construction of 100% sealed,
watertight control panels that are immune to humidity, temperature, dirt accumulation, or the physical deterioration of the panel surface
from abrasion, chemicals, or abuse. To this end they contain Quantum-pioneered adaptive auto self-calibration, drift compensation, and
digital filtering algorithms that make the sensing function robust and survivable.
These devices feature continuous FMEA self-test and reporting diagnostics, to allow their use in critical consumer appliance
applications, for example ovens and cooktops.
Common PCB materials or flex circuits can be used as the circuit substrate; the overlying panel can be made of any non-conducting
material. External circuitry consists of only a few passive parts. Control and data transfer is via an SPI port.
These devices makes use of an important new variant of charge-transfer sensing, transverse charge-transfer, in a matrix format that
minimizes the number of required scan lines. Unlike older methods, it does not require one IC per key.
