TDK Corporation (TSE:6762) introduces the Micronas HAL 13xy family, a factory-programmable Hall-effect switch sensor designed for speed and direction detection in automotive and industrial applications. Leveraging TDK-Micronas’ proven 3D HAL technology, HAL 13xy features three orthogonal Hall elements (X, Y, Z) arranged in a pixel cell, providing 90° phase separation (quadrature signal) that is inherently independent of magnet pole spacing and air gap. This design enables the simultaneous measurement of two magnetic-field components, offering manufacturers maximum flexibility in sensor and magnet placement.

For the automotive sector, the HAL 13xy family can be employed in applications such as seat-track motors, sunroof drives, tailgate motors, valve position, steering column motors, steering turn-count sensing, and window lifters with anti-pinch functionality. *  
Start of production is planned for October 2026. Samples are already available.

HAL 13xy delivers two independent open-drain outputs, which can be configured for quadrature speed/speed or speed/direction signals. This flexible output configuration supports compact electric motor control in applications that require precise, reliable, and space-saving sensing technology. With its robust design and versatile outputs, HAL 13xy helps enable smooth motion control, high safety standards, and enhanced user comfort.

Designed for robustness and long-term reliability, HAL 13xy operates from –40 °C to 170 °C junction temperature, supports a wide supply voltage range from 3.0 V to 24 V, and provides strong protection features, including 40 V load dump robustness, -18 V reverse-voltage protection, and short-circuit/thermal protection. The device maintains constant switching points across supply voltage and temperature variations, ensuring stable performance in demanding environments. It is qualified to AEC-Q100 standards for automotive electronics and offers high EMC resilience according to ISO and IEC requirements.

As a Safety Element out of Context (SEooC), and with integrated continuous built-in self-test (BIST), HAL 13xy is ASIL B ready in accordance with ISO 26262, making it suitable for integration into automotive safety-related systems. The sensor operates with both static and dynamic magnetic fields up to 40 kHz and is compatible with a variety of ferrite and rear-earth magnet types, thanks to multiple temperature coefficient options.

With its compact 5-pin SOT23 package, high ESD robustness (up to 4 kV HBM), and configurable sensing axes, the HAL 13xy family gives engineers a versatile and cost-effective solution for precise motor control and position detection in space-constrained automotive and industrial applications.
