Overview

Product Highlight

  • Type: Adapter Boards
  • Core Supported: AS5045

The AS5045 is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front-end and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet may be placed above or below the IC.

The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0875° = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal. The PWM pulse width is programmable for 1s/step or 2s/step (244Hz or 122Hz PWM frequency). An internal voltage regulator allows the AS5045 to operate at either 3.3 V or 5 V supplies.

Features:

  • 360° contactless high resolution angular position encoding
  • Two digital 12-bit absolute outputs:
    • Serial interface and
    • Programmable Pulse Width Modulated (PWM) output
  • User programmable zero position
  • Failure detection mode for magnet placement monitoring and loss of power supply
  • Push button functionality detects movement of magnet in Z-axis
  • Serial read-out of multiple interconnected AS5045 devices using daisy chain mode
  • Mode input for optimizing noise vs. speed
  • Wide temperature range: -40 to +125°C
  • Small package: SSOP-16 (5.3mm x 6.2mm)

Applications:

  • Industrial applications:
    • Contactless rotary position sensing
    • Robotics
  • Automotive applications:
    • Steering wheel position sensing
    • Gas pedal position sensing
    • Transmission gearbox encoder
    • Headlight position control
    • Power seat position indicator
  • Replacement of potentiometers
  • Front panel rotary switches
