AT42QT1010
The AT42QT1010 is part of Atmel's family of SingleTouch touch button controllers. The AT42QT1010 supports a single capacitive touch button and can be used to replace a traditional mechanical switch in many designs. The device can be configured to work through a range of panel thicknesses and materials through careful capacitor selection. The device can also be used in proximity sensing applications. The AT42QT1010 requires just 3 external components.
The AT42QT1010 has a 'Max On' setting which prevents the 'Stuck-key' condition from occurring when an obstruction is detected for prolonged period of time. After the time period the key will re-calibrate, allowing subsequent touches to be detected.
The EVK1010A evaluation kit can be used to appraise the performance of the AT42QT1010.
