Overview

The ALS31313KLEATR-500 is a high-performance 3D Hall-effect sensor designed for 12-bit linear and rotary position sensing applications. This AEC-Q100 qualified device measures magnetic field components across the X, Y, and Z axes and communicates via an I2C interface, making it ideal for low-power automotive and industrial control systems.

Why Choose This Part

The sensor offers exceptional power efficiency with a sleep current of only 14nA and a low-power duty cycle mode for battery-operated devices. Its integrated 12-bit ADC provides high-resolution data with 10-bit effective number of bits (ENOB), while the automotive qualification ensures operation across a wide -40 to 125 degree Celsius temperature range.

Applications

Joystick Controllers
Provides precise X and Y axis tilt sensing with Z-axis 'crouch' or push-button detection for gaming or industrial machine control.
Rotary Knobs and Dial Encoders
Enables non-contact rotary position sensing for rugged human-machine interfaces in automotive dashboards or appliances.
Anti-Tamper Sensors
Detects three-dimensional magnetic field changes to identify unauthorized attempts to interfere with smart meters or security systems.
Automotive Shift Levers
Tracks gear selector positions in automotive transmissions with high reliability and AEC-Q100 compliance.

Getting Started

Engineers can evaluate this part using the ASEK-31313-T-KIT evaluation board and Allegro's provided GUI software for real-time magnetic data visualization. The I2C interface allows for easy connection to any standard microcontroller using a 3.3V logic level, and the internal EEPROM can be programmed to store custom configuration and calibration parameters.
