ATS344 - High-Precision Linear Hall-Effect Sensor

General Description

The ATS344 device is a high-precision, back-biased programmable Hall-effect linear sensor integrated circuit (IC) with a conf igurable current-mode pulse-width-modulated output, for both automotive and non-automotive applications.

Key Features

  • Magnetic sensor IC with integrated rare-earth pellet.
  • Two-wire current mode PWM (pulse-width modulation) output.
  • Customer-programmable position range selection and offset, bandwidth, output clamps, and temperature compensation.
  • Sensitivity temperature coeff icient and offset drift preset at Allegro.
  • Temperature-stable, mechanical stress immune, and low noise device output via proprietary active stress compensation and four-phase chopper stabilization.
