A31316: 3D PCB-less Hall-Effect Sensor for Rotary and Linear Measurement

Description

The A31316 is a robust, fully integrated 3DMAG™ Hall-effect magnetic position sensor IC designed to support a wide range of non-contact rotary and linear position measurement in the automotive, industrial and consumer applications.

The A31316 is available in a PCB-less SIP package with an integrated supply capacitor. The sensor has high robustness to mechanical vibration and contamination and can be over-molded or potted with plastic or epoxy for a tight seal.

This family of sensors integrates vertical and planar Hall-effect elements to detect two out of three magnetic field components (X,Y and Z). Using configurable signal processing, linearization and angle calculation allows the A31316 to accurately resolve the absolute rotary (full 360° and short-stroke <360°) or linear position of a moving magnetic target.   

The A31316 features PWM or SENT (SAE J2716) interface options to output the angle between the two factory-selected axes or the field from a single axis. In addition, the SENT interface provides the option to output the field measurement from both channels.

Top Features

  • PCB-Less “UC” Package for system integration without a PCB
  • Linearization and binning modes (up to 33-point fixed, up to 22-point programmable positions)
  • Supports SENT (SAE J2716) and PWM interface options
  • Developed in accordance with ISO 26262 as a hardware safety element out of context (SEooC) with ASIL B
  • AEC-Q100 Grade 0 qualified supports operation in harsh conditions, required for automotive and industrial applications
