ALS31313 Datasheet 3-d Linear Hall-effect Sensor

Manufacturer: Allegro MicroSystems

Overview: ALS31313 Automotive Grade, 3D Linear Hall-Effect Sensor with I2C Output and Advanced Low Power.

General Description

TheALS31313 3DMAG™ linear Hall-effect sensor IC provides a 12-bit digital value corresponding to the magnetic field measured in each of the X, Y, and Z axes.

The ALS31313 is preconfigured for use in 3D sensing applications for head-on linear motion, slide-by position sensing, and rotation angle measurements.

TheALS31313 is also offered in joystick mode, including a low gain option for the Z axis channel.

Key Features

  • AEC-Q100 automotive qualified.
  • Senses magnetic fields in X, Y, and Z axes.
  • Z-axis sensing of “crouch” or push button motion.
  • Capable of operating with back-bias magnets.
  • Ideal for battery-powered, low-voltage.
