AT42QT1012-MAHR More Semiconductors - ICs by Microchip Technology
| Status: | Active |
|---|---|
| Series: | AT42QT1012 |
| RoHS: | Compliant |
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 AT42QT1012 has touch-on/touch-off (toggle) functionality and a Auto Off timer to save on power consumption.
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.
