Capacitive button systems are not simple to design and provide a few major design problems. Reliable capacitive button solutions are difficult to implement and require specialized technical expertise. Different types of capacitive button overlays, such as curved or thick overlays, reduce button SNR performance. Capacitive button solutions require time-consuming manual tuning for robust performance. Secondly, water droplets can cause false touches in capacitive button solutions, and most capacitive button solutions will not work under water droplets or streaming water. Lastly, advanced features like proximity sensing complicate the design; proximity sensor reliability can be impacted by system and environmental changes. CapSense MBR solves these problems by making capacitive buttons easy to implement with a Register-Configurable Solution, even with curved or thick overlays. It eliminates the need for manual tuning by providing SmartSense auto-tuning. CapSense MBR works in wet and misty environments, and provides a reliable, easy-to-implement proximity sensor solution. CapSense MBR is an easy way to create reliable, water-tolerant capacitive buttons and proximity sensing.
