Consumer behaviors and escalating global factors in multiple geographies and legislative bodies are driving growth in electrification. Europe, Asia, and North America are seeing an uptick in sales of EVs as incentives grow and fossil fuel use is discouraged.
In this context, the demand for current sensing technologies is rapidly growing. The current sensor market requires high volumes and cost-effective products.
Leading the world in electrical measurement, LEM is building on its 50 years of knowledge and expertise, and its proficiency in ASIC design to develop a full range of ICS to meet new customer current sensing needs. LEM R&D team is constantly investigating for improvements and technological solutions that allow to make a difference. TMR, Tunnel Magneto Resistance, is one of these promising technologies.
TDK Corporation and LEM announce they have entered into a development agreement of custom TMR (Tunnel Magneto Resistance) dies for next-generation integrated current sensors.
TDK will develop tunnel magnetoresistance (TMR) dies for LEM and LEM will incorporate these TMR dies into integrated current sensors (ICS).
This collaboration will further position TDK’s TMR technology in the automotive and industrial markets, two sectors in which LEM brings deep expertise, especially in booming segments such as energy storage, motor drives, and solar inverters. TDK expects to bolster its market position on magnetic sensors by offering superior products that support existing and upcoming applications in market trends like energy transformation (EX) and digital transformation (DX).
LEM selected TDK as a partner based on its best-in-class technology performance – including accuracy and noise – as well as reliable supply, automotive quality, and process maturity.
TDK and LEM will produce a TMR-based sensor that is faster, more accurate, and with lower noise than existing solutions.
