A19571 Datasheet Gmr Transmission Speed And Direction Sensor

Manufacturer: Allegro MicroSystems

Overview: A19571 Large Air Gap, Vibration-Tolerant, GMR Transmission Speed and Direction Sensor.

General Description

The A19571 is a magnetic sensor integrated circuit (IC) that uses giant magnetoresistance (GMR) technology to encode the speed and direction of rotating ring magnets.

Using a state-ofthe-art GMR stack design integrated with a BiCMOS process, the IC differentially measures magnetic fields and applies advanced digital processing to robustly measure ring magnets commonly used in automotive transmissions.

The A19571

Key Features

  • GMR technology delivers high magnetic sensitivity for large air gaps and minimal jitter.
  • SolidSpeed Digital Architecture provides robust, adaptive performance with advanced algorithms that provide vibration immunity over the full target pitch.
  • Flexible orientation allows parallel or perpendicular placement to the magnet.
  • ISO 26262 ASIL B with integrated diagnostics and certified safety design process.
  • EEPROM enables traceability throughout product li.
