ATS19420 - High-Accuracy Hall-Effect Transmission Speed Gear Tooth Sensor

General Description

The ATS19420 is an advanced Hall-effect integrated circuit (IC) that uses a fully integrated back-biased magnet to measure the speed of rotating ferrous targets.

Key Features

  • Differential Hall-effect sensor measures ferrous targets with inherent stray field immunity.
  • SolidSpeed Digital Architecture supports advanced algorithms, maintaining pitch and duty cycle accuracy during dynamic air gap disturbances.
  • Integrated solution includes back-biased magnet and capacitor in a single overmolded package.
  • ISO 26262:2011 ASIL B with integrated diagnostics and certified safety design process.
  • Two-wire current source output protocol.
