The AT42QT1050-MMH is a bidirectional QTouch device that combines touch button and sliders with a hardware and software architecture optimisation. It enables the user to customize their applications according to their needs. The auto-configurable capacitive touch detection makes this device ideal for use in both portable and non-portable applications. This device is intended for use with both capacitive touch screens and capacitive touch buttons as application fields.

The AT42QT1050-MMH combines a QTouch process engine with a hardware interface to enable the device to detect and respond to touch events. It contains a 16-bit processor and a dual-channel eXtended-range hardware comparator. The hardware is tailored for capacitive touch button and slider designs to enable fast response times. The processor can be programmed using the QTouch Composer software for customisation across different application fields.

The AT42QT1050-MMH utilises a combination of hardware and software components to detect and respond to touch. It utilises a self-calibrating process engine to continuously monitor the electrical performance of the capacitive touch button and slider sensor. The device continuously monitors the capacitance of the sensor and compares the data with a user-programmed threshold value. When the threshold value is exceeded, an interrupt request is sent to the processor, indicating that a valid touch has been detected.

The detecting process of the AT42QT1050-MMH is further enhanced by the auto-configurable sensing mode. This enables the device to optimise the detection process to fit the application field. The auto-configurable sensing mode can be used in applications which require both instant response times and low energy consumption. The auto-configurable sensing mode helps to provide the best possible performance across different application fields.

The AT42QT1050-MMH is also equipped with a self-calibration mode. This mode allows the system to refine the detection process and to improve responsiveness. The self-calibration process also helps to reduce the amount of energy needed to run the device. This helps to improve the device’s efficiency and power consumption.

In conclusion, the AT42QT1050-MMH is an ideal device to be used in applications where order to detect and respond to touch events, such as portable and non-portable applications. The combination of self-calibrating process engine and auto-configurable sensing mode allows the device to provide the best performance across different application fields. The self-calibration mode also helps to reduce power consumption, thus improving device efficiency and power consumption.
