ATEVK1010A

The ATEVK1010A is a Single Key Capacitive Touch Controller, provide touch key replacements for mechanical buttons. The IC as such can be added to designs with minimal impact on the bill of materials. Single key with timer to reset stuck key condition. The AT42QT1010 has a maximum on duration of 60 seconds. If there is an obstruction on the sensor, the device output will go low after the maximum on detection period, so that subsequent touches can be detected.

• Low power consumption (17µA at 1.8V)
• Range of response speed settings
• Can be configured for use as a proximity sensor
• Drift compensation
• Spread spectrum acquisition
• Sensitivity, calibration and detection
• The device will automatically calibrate on power up
• ICs include signal processing which helps to suppress detections caused by electrical noise
