Overview

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.

  • 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 applications □ 2.65 to 3.5 V single supply operation □ 1 MHz I2C compatibility down to 1.8 V □ 14 nA (typ) Sleep ICC □ 12 µA to 2 mA ICC (typ) in low-power duty cycle mode
  • Industry standard I2C interface for easy system integration □ Up to 1 MHz (Fast Mode+) I2C communication □ 16 selectable addresses via external resistor divider □ 127 available address configurable via EEPROM
  • On-chip EEPROM □ Stores factory- and user-configured settings □ 78 bits of user EEPROM for additional storage □ On-chip charge pump for easy programming Continued on next page... PACKAGE: Z 8-Pin TSSOP (LE) X Y Not to scale
