TI launched a new 3D Hall effect position sensor with high speed and high precision to achieve faster real-time control

     Texas Instruments introduced TI precise 3D Hall effect position sensor. With the TMAG5170, engineers can achieve ultra-high accuracy without calibration at speeds up to 20 kSPS, allowing faster and more accurate real-time control in factory automation and motor drive applications. The sensor also provides integrated functions and diagnostic features, which can improve design flexibility and system security to a greater extent, and its power consumption is at least 70% lower than that of similar devices. TMAG5170 is the first device in TI's new 3D Hall effect position sensor series, which can meet various industrial requirements, including ultra-high performance applications and general-purpose applications.

     "Smart factories have more and more highly automated systems that must operate in more integrated manufacturing processes while simultaneously collecting data to control processes," said Noman Akhtar, senior research analyst at Omdia. "3D position sensing technology with higher accuracy, speed and energy efficiency is critical for automation equipment, which can quickly achieve accurate real-time control to improve system efficiency and performance while reducing downtime."

     The TMAG5170 is TI's first 3D Hall effect position sensor, providing total error at full scale as low as 2.6% at room temperature. It also has an overall error drift of as low as 3% (at least 30% lower than comparable competitors) and an error of at least 35% lower than comparable devices in the presence of an axial field. Together, these features enable the TMAG5170 to provide higher accuracy than any other 3D Hall effect position sensor, simplifying system design and manufacturing without terminal calibration and off-chip error compensation. For faster and more accurate real-time control, the sensor supports measurements up to 20 kSPS, enabling low-latency throughput for high-speed mechanical movements.

     The TMAG5170 eliminates the need for off-chip computation and enables flexible orientation of sensors and magnets through integrated features such as an Angle calculation engine, mean measurement, and gain and offset compensation. These features simplify the design and increase system flexibility to achieve faster control loops, reduce system latency, and simplify the software development process, regardless of sensor placement. The sensor's integrated computing capabilities also reduce the system's processor load by up to 25%, enabling engineers to use general-purpose MCUS, such as TI's low-power MSP430™ MCU, to further reduce the total system cost.

     In addition, the TMAG5170 improves security with a unique set of intelligent diagnostics (such as checking communication, continuity, and internal signal paths) and diagnostics that can be configured for external power supplies, magnetic fields, and system temperature. As a result, engineers are able to customize chip - and system-level security solutions, achieving long-term reliability and lower design costs.

     The TMAG5170 offers a variety of operation modes and can reduce power consumption by at least 70% compared to other linear 3D Hall effect position sensors while maintaining system performance. With these configurable modes, engineers are able to reduce power consumption in the sampling range of 1 SPS to 20 kSPS for battery-powered devices or in light load modes that focus on system efficiency.
