It is an integrated chip and associated sensing platform designed to detect and process the human touch. It provides a simple, reliable and cost-effective solution for capacitive touch interface, offering cost reduction and an improved user experience.

Application Fields

QT60240-ATG provides a variety of application fields for capacitive touch sensing, including home appliances, automotive, industrial, medical and portable device applications. It offers a high level of sensitivity and accuracy, meaning that it can accurately detect even very fine touches, allowing a user to intuitively operate the interface. The chip can also detect fingers, stylus, pincher and even gloves made of different materials.

Integrated Features

The QT60240-ATG chips offer a range of integrated features, such as noise reduction, crowding tolerant detection and sensor break away detection, among others. Noise reduction enables the chip to reduce interference from other sources and provide a reliable and accurate touch screen experience. Meanwhile, crowding tolerant detection allows the chip to detect multiple touches on the surface of the screen at the same time. Lastly, sensor break away detection provides a way to detect any touch surface movement, allowing for more accurate gesture control.

Working Principle

The working principle behind the QT60240-ATG is based on capacitive touch sensing. This technology works by measuring the capacitance of a touch sensor. When the user places their finger or hand on the sensor, the capacitance increases, which is detected by the QT60240-ATG chip. The chip then processes this signal, allowing the user to interact with the touch interface.

Conclusion

QT60240-ATG is a versatile and reliable capacitive touch sensing platform that provides a simple and cost-effective solution for capacitive touch interfaces. It offers a wide range of integrated features and a high level of sensitivity and accuracy, allowing users to intuitively interact with a touch interface. The chip’s working principle is based on capacitive touch sensing, making it an ideal choice for a variety of applications.
