About Yole Group

Magnetic sensors are widely used in automotive, mobility, industrial, infrastructure, and consumer applications. Yole Intelligence estimates that the overall magnetic sensor market will reach almost $4.5B in 2027, with a 9% CAGR21-27 (volume and revenue growth). This is primarily due to the increase of electrification and “sensorization” of cars, though the demand for consumer and industrial applications also follows the same trend. 

Since we have noted an increasing interest for TMR (tunnel magnetoresistance) sensor technology, we propose a report on this topic. TMR sensors are a type of magnetic sensor widely used in a variety of applications, ranging from automotive and industrial to medical and consumer electronics. TMR sensors are based on the tunneling effect of electrons through a thin layer of insulator between two ferromagnetic layers, which results in a large change in resistance in the presence of a magnetic field.

We have selected 21 different devices that use TMR technology, providing a deep comparative review of the technology, supply chain, and cost. We wanted to understand the differences between all the magnetic sensor functions (e.g., position, current, speed, switches / latches) that employ this technology. The products analyzed in this report come from the main market suppliers: BOSCH, Crocus Technology, TDK, Infineon, MultiDimension Technology, NVE Corporation, Coto Technology, and ABLIC.

YoleSystemPlus has analyzed these sensors to provide insights regarding their structure, technology, process integration, and manufacturing cost of the main processes. Using our expertise in package opening, die decapsulation, delayering, cross-sectioning, SEM pictures, and material analyses, we have overviewed the ASIC modules (size, technology node, functions / outputs), the magnetic sensor part (layout, sensing area, materials), and the package (substrate type, dimensions).
