The AT42QT101x Single Key capacitive touch controller family provides an easy way to add a touch key to any application. It implements advanced filtering algorithm to offer robust operation in noisy environment. Sensitivity and low power modes can be configured as well.
The AT42QT1010 has "maximum on" touch duration of ~ 60s. The device output will then go low and a subsequent touch event can be detected.
The AT42QT1011 output will remain high as long as a touch is detected. No "Max On" time out.
The AT42QT1012 has touch-on/touch-off (toggle) functionality and a Auto Off timer to save on power consumption.

| Cap Touch click is a capacitive touch sensing button, integrated on a click board™. It can be activated by touch. This click can sense touch even through plastic, wood, or other dielectric materials, which can be used to protect the surface of the PCB and the sensor pad trace itself. Unlike the mechanical button, the capacitive touch button lasts much longer, it is not prone to damage and wear over time and it is very reliable.
Capacitive buttons are a very popular method of powering up various devices. Besides the aforementioned benefits, having a touch sensitive button on a device allows for a compact design, opens possibilities for various kinds of human-machine interface and - it looks good and modern, especially if accompanied by a LED that turns on when activated, just like the one on Cap Touch click. Cap Touch click can find its place among many applications - for touch activated lighting controls, touch activated control panels, toys and any other applications that need a switch or a button. |
