Spotlight on 3D Hall Sensors – Part 2:
TDK Micronas HAL35

In the first part of this series, we introduced the HAL37.

It is the cost-effective solution for applications where reliability and efficiency are the primary requirements.

But what happens when system requirements become more demanding?
When different magnet concepts need to be supported. When higher accuracy is required. Or when developers want greater control over the sensor output without immediately moving to the highest-performance solution.

This is exactly where TDK's Micronas HAL35 comes into play.

The Perfect Balance of Performance and Flexibility

A typical development project often starts with clear requirements: detect position, determine angle, and provide a signal output.

As development progresses, however, additional requirements frequently emerge. Accuracy needs to be improved. Different magnet arrangements must be supported. The output signal should be adaptable to the specific application. At this point, simple standard sensors often reach their limits.

At the same time, a high-end solution may introduce unnecessary complexity and cost. This is where the HAL35 demonstrates its strengths.

The HAL35 is based on Micronas' proven 3D HAL® technology, which captures multiple magnetic field components simultaneously. The resulting position and angle information can be flexibly adapted to a wide variety of applications and magnet concepts.

Its key advantage lies in its programmability. Compared to the HAL37, developers gain significantly greater freedom in defining transfer characteristics, signal processing, and application-specific customization.

Why the HAL35 Is the Optimal Choice for Many Applications

• Greater Design Freedom
  The programmable transfer characteristic enables precise adaptation to different magnet concepts and application requirements.

• Higher Accuracy
  Compared to the HAL37, the HAL35 offers improved precision and enhanced robustness.

• Attractive Price-to-Performance Ratio
  The HAL35 is positioned exactly where many projects need it most: between an entry-level solution and maximum functionality.

• Design Flexibility
  Compact SOIC8 and SOIC16 package options simplify integration into industrial and automotive applications.

• Redundancy for Enhanced Safety Requirements
  For safety-critical applications, the HAL35 is also available as a dual-die version. Two independent sensor chips within a single package enable redundant measurements and plausibility checks without requiring additional board space.

The HAL35 is particularly well suited for:

• Precise position and angle measurement
• Position feedback systems
• Automotive applications
• Industrial automation
• Applications requiring support for different magnet concepts

The Ideal Balance Among 3D Hall Sensors
The HAL35 bridges the gap between the cost-optimized HAL37 and the high-performance HAL39. It provides developers with exactly the additional flexibility and accuracy that many applications require. In short, the HAL35 is the sensor for engineers who need more possibilities—without adding more complexity than necessary.

In the next and final part of our series, we will introduce the HAL39—the flagship of the 3D Hall sensor family for particularly demanding position and angle measurement applications.
