APPLICATIONS

QT1100A charge-transfer (“QT”) QTouch ICs are self-contained digital controllers capable of detecting near-proximity or touch on up to

10 electrodes. This device allows each electrode to project an independent sense field through glass or plastic. These devices require

only a few inexpensive passive components per sensing channel. The devices are designed specifically for human interfaces, such as

control panels, appliances, gaming devices, lighting controls, or anywhere a mechanical switch may be found.

Each key channel operates independently, and can be tuned to a unique sensitivity level by simply changing setup values in an

EEPROM or via a serial interface. An external EEPROM can store the setups permanently for standalone applications, for example

when using the scanport, or, the EEPROM can be omitted if the serial port is used to send setup information after each power-up.

Included is patent pending AKS™ Adjacent Key Suppression which suppresses touch from weakly responding keys and allows only a

dominant key to detect, to solve the problem of large fingers on tightly spaced keys. Modulated burst technology provides superior

noise rejection. ‘Fast-DI’ operation works to further suppress false activations due to noise.

These devices also have a Sync pin to suppress some forms of external interference. A Sleep mode is also available for very low

power standby operation.

The QT1100A is designed specifically to assist in creating FMEA compliant designs, allowing it to be used in applications such as

appliance controls.

Using the charge transfer principle, these devices deliver a level of performance which is clearly superior to older technologies yet

extremely cost-effective.
