Two Wire Hall Effect Sensor ALLEGRO ATS19200LSNATN-H with Integrated EEPROM and ASIL B Safety Rating
Product Overview
The ATS19200 is an optimized Hall-effect integrated circuit (IC) designed for true zero-speed digital gear tooth sensing in two-wire applications. It integrates a rare-earth pellet and a high-temperature ceramic capacitor within a single overmolded package, enhancing EMC robustness and simplifying design-in. Featuring an advanced threshold switching algorithm, it delivers high accuracy for pitch and duty cycle across a wide operating air gap range. The device is ASIL B(D) rated, supported by integrated diagnostics and a certified safety design process. An integrated EEPROM provides device traceability throughout production. The ATS19200 is ideal for automotive and two-wheeler braking systems, offering a user-friendly solution with a two-wire current source output that supports speed and ASIL protocols.
