Microchip Technology QT60168ASG Touch Key Sensor
The QT60168-ASG is a second-generation digital charge-transfer QProx IC designed for flexible touch key sensing. It detects up to 16 keys on a scanned passive X-Y matrix, capable of projecting signals through dielectrics up to 50mm thick. The key areas are defined by simple interdigitated electrodes made of copper, silver, or carbon. Features include individual sensitivity adjustment, auto-calibration, adjacent key suppression, spread-spectrum noise immunity, and minimal external components. Ideal for sealed, durable touch panels in appliances, security, and industrial controls, it offers high robustness against environmental effects and vandalism with integrated self-test diagnostics.
