Functional Description

It is an impressive piece of engineering, and its capabilities in taking accurate angular measurements are revealed by the functional description. This angular magnetic encoder IC is a technological marvel that achieves unprecedented accuracy because it is manufactured using a CMOS standard process and makes use of Hall technology.

Hall Technology at the Core

It is built around a core of integrated Hall components. These components are thoughtfully arranged around the device’s core. Their main job is to detect magnetic fields all over the chip’s surface. To get an accurate voltage representation of the magnetic field at the IC’s surface, Hall components are used.

Digital Signal Processing (DSP) Magic

The Hall sensor provides more information than merely voltage readings. Digital signal processing (DSP) circuit is where the magic happens with this information. The data from the Hall sensor must be converted by this circuit into two important forms:

  • Absolute Angular Position: The first is the absolute output, which is represented by the DO/DI pin and conveys accurate angular position data. This allows you to immediately determine the precise angle at which the magnet is set in relation to the IC.
  • Digital Output: The incremental circuit also produces a digital output (A/U, B/V, I/W pins). When incremental measurements are required, this digital output comes in handy.

MagHi and MagLo Outputs

The AEAT-6600-T16, however, has additional features. The MagHi and MagLo digital outputs are also included. These readings reveal whether or not the magnet is drawing nearer or distant from the integrated circuit. Applications that need to keep tabs on the magnet’s vicinity will find this data extremely useful.

Magnet’s Role

For angular position data, the AEAT-6600-T16 uses a conventional magnet with diametric magnetization (two poles). The IC detects the magnet’s rotational direction as it passes over its center. The IC can use this method to convert a binary code from 10 bits to 16 bits.

Output Modes

The angular information generated by the AEAT-6600-T16 can be accessed through different output modes:

  1. Synchronous Serial Interface (SSI): This interface provides a convenient way to access the binary code representing the angular position.
  2. Pulse-Width Modulated (PWM) Signal: For those who prefer an absolute angular representation, a PWM signal is available at pin 8, making it easy to integrate into digital systems.

Tolerance to Magnet Misalignment and Stray Fields

It is particularly noteworthy how resistant the AEAT-6600-T16 is to magnet misalignment and stray magnetic fields. Because it makes use of a local measuring technique and Hall sensor conditioning circuitry, the integrated circuit is in a position to deliver accurate results even in conditions that are less than ideal.

It is a masterpiece that exemplifies the successful marriage of cutting-edge technology and painstaking handiwork. Its capacity to convert data from magnetic fields into accurate angular measurements contributes to its versatility, making it applicable to a wide range of applications, from industrial automation to robotics. This functional explanation makes it abundantly evident why this remarkable instrument is regarded as a cornerstone of modern angular measuring technology.

In Conclusion

The AEAT-6600-T16 is a game-changer in the realm of angular measurement. Its combination of contactless magnetic technology, customizable features, and impressive technical specifications make it an ideal choice for a variety of applications in industrial automation and beyond. Whether you are seeking precision in brushless motor control or a reliable alternative to outdated sensors, the AEAT-6600-T16 stands as a technological beacon, leading the way in accurate angular measurement.
