The QT111 is a touch sensor IC having recalibration timeouts (“max on-duration”) of 5 minutes and infinity.
Applications
* where continuous touch over long periods is desired, like hand-on-joystick sensors, dead-man switches, etc. Although the primary application of the device is still as a ‘touch sensor’, longer timeouts also aknowledge alternate uses for the QT110 family, for example in process controls.
