Touch key IC which can detect human body contact using external touchpads. The high level of device integration enables applications to be implemented with a minimum number of external components.
Special internal circuitry is also employed to ensure excellent power noise rejection to reduce the possibility of false detections, increasing the touch switch application reliability under adverse environmental conditions.
With auto-calibration, low standby current, and a choice of wake-up features, this range of touch key devices provides a simple and effective means of implementing touch switches in a wide variety of applications.
