General Description

The A1693 is a magnetic sensor IC designed for measuring the speed and direction of rotating transmission systems.

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

The IC incorporates three Hall-effect elements that sense differentially, analog signal conditioning with dynamic gain and offset adjustment, analog-to-digital converters (ADCs), and a digital processor that applies intelligent algorithms to prevent the output from switching when the sensed target vibrates.

Overview

A1693 Vibration-Tolerant Hall-Effect Transmission Speed and Direction Sensor.

Key Features

  • Differential Hall-effect sensor IC measures ring magnets and ferrous targets with inherent stray field immunity.
  • Vibration detection algorithms prevent false switching and provide low-signal lockout.
  • Large operating air gap with independent switch points.
  • Three-wire pulse-width output protocol describes speed and direction.
  • Wide operating voltage and integrated protection circuits.
  • AEC-Q100 Grade 0 qualified for an ambient operating temperat.
