Microchip TechnologyAT42QT1011-TSHRIC: driver/sensor
The Microchip 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. It output will remain high as long as a touch is detected. No Max On time out. Electrode design Solid or ring electrode shapes PCB Layers required One Electrode materials Etched copper, silver, carbon, Indium Tin Oxide Panel thickness Up to 12 mm glass and 6 mm plastic electrode size and Cs dependent Key sensitivity Settable via capacitor Power consumption 17 μA at 1.8 V typical
