A19520 - Transmission Speed and Direction Sensor

Description

The A19520 is an advanced vibration-tolerant Hall-effect integrated circuit (IC) that measures the speed and direction of rotating targets.

This sensor IC can directly measure ring magnets or be back-biased with a magnet to measure ferrous targets.

Features

  • Differential Hall-effect sensor measures ring magnets and ferrous targets with inherent stray field immunity.
  • SolidSpeed Digital Architecture provides robust, adaptive performance with advanced algorithms that provide vibration immunity over the full target pitch.
  • Integrated solution includes a capacitor in a single overmolded miniature package.
  • ISO 26262:2011 ASIL B with integrated diagnostics and certified safety design process.
  • Two-wire current so.
