Product Release QT102 QTouch™ Sensor IC
05.09.2007
The QT102 capacitive touch sensor IC is a self-contained, all-digital product combining a single channel touch sensor with integrated system power management functions.
The QT102 is a digital burst mode charge-transfer (QT) sensor designed specifically for touch controls; it includes all of the required hardware and signal processing functions necessary to provide high performance capacitive touch-sensing under the broadest range of operating conditions. Only a few passive external components are required to implement the sensor in a typical application.
The user definable auto shut-off feature of the QT102 addresses power management in applications which are battery driven and can help to provide a safety margin in, for example, small appliances. The off-timer override function can be used to integrate the chip as part of a broader system environment where an external device, such as a passive infrared sensor as part of a lighting control circuit, can determine the shut-off behaviour of the circuit.
Applications:
• Kitchen Appliances
• Flashlights
• Stereo Systems and TV
• PC and PC Peripherals
• Toys
