Touch controller consumes just 0.5μA in active-idle state

As little as 0.5μA is consumed by the device when in its active-idle state. According to Aito, this is significantly less than competing touch control devices. Allowing touch buttons to be integrated into metal and other surfaces, the controller is based on the company’s SEP technology. In combination with up to 15 LED indicator and buzzer outputs, the ATB352 supports up to five piezo touch key inputs.

The piezo sensing parameters for each key can be individually configured for sensitivity and detection area. Each key can also be configured to cope with overlay stiffness or mechanical integration conditions. For a customised feedback pattern, the LED indicator and audible buzzer responses for each button can also be individually configured. The ATB352 AitoTouchLE Controller is suitable for home automation, battery-powered equipment and wearbles.

"Applications which rely on battery power, or even energy harvesting, demand the most efficient design solutions", said Peter Kurstjens, Chief Commercial Officer, Aito. "But equally, these products deserve to benefit from the design aesthetics and quality user experience that our current AitoTouch products offer - which is exactly what the new AitoTouchLE family now delivers."

Kurstjens adds, "The key Aito feature of robust and reliable operation, even with gloved hands or in the presence of water or other surface contaminants, is as vital for personal appliances and wearable devices as it is in more established applications such as kitchen appliances or medical electronics."
