ATS694LSM - Crankshaft Position Sensor

General Description

The ATS694LSM is a combined Hall-effect sensing integrated circuit, back-biasing rare-earth pellet, and EMC protection circuit that provides a user-friendly, PCB-less solution for true zero-speed digital crankshaft sensing.

Key Features

  • Allegro SM package with integrated EMC components provides robustness to most automotive EMC requirements.
  • Integrated back-biasing rare-earth pellet.
  • Digital output with speed and direction information provides ferromagnetic target position information.
  • Enhanced algorithms provide low jitter and high output accuracy performance.
  • Electrical offset compensation through chopper stabilization.
  • Dual zero-crossing with internal hysteresis.
