TDK and LEM set to collaborate on next-generation TMR-based ICS

TDK Corporation and LEM International SA announce that they have entered into a development agreement of custom TMR dies for next-generation integrated current sensors.

TDK will develop tunnel magnetoresistance (TMR) dies for LEM. LEM will incorporate these TMR dies into their integrated current sensors (ICS), a critical component used in rapidly expanding electrification applications like onboard chargers (OBCs) in EVs.

This collaboration will further position TDK’s TMR technology to succeed 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).

“As the technology leader of magnetic sensor solution provider, we are proud of this collaboration,” said Takao Tsutsui, CEO of the Sensor Systems Business Company of TDK Corporation. “The combination of our TMR technology and LEM’s expertise in electrical measurement will generate outstanding new products for various market segments requiring electrification”.

“LEM is convinced about the benefits of this collaboration, and feedback from our customers has already been very positive regarding a next generation of TMR-based integrated current sensors,” stated Frank Rehfeld, CEO of LEM. “These positive reactions, the megatrend in electrification, and TDK’s and LEM’s deep expertise will contribute to the success of this collaboration.”
