The ATS684LSN is an integrated Hall-effect sensor IC designed for zero-speed, differential gear tooth sensing applications. It combines an industry-proven IC, rare-earth magnet, and high-temperature ceramic capacitor in a single overmolded package, offering EMI protection and simplifying system design. Its advanced algorithms provide immunity to signal perturbations from vibration, ferrous debris, target eccentricities, and harsh automotive conditions, making it ideal for safety-critical automotive applications like transmission speed sensing. The sensor features adaptive threshold sensing for optimized performance across various target types and includes Scan, Iddq, and Built-In Self-Test capabilities for enhanced dependability.
