MultiDimension Technology Co., Ltd.: MDT Introduces Upgraded TMR Switch Sensors for Industrial, Medical and Automotive Applications

MDT Expands TMR Magnetic Sensor Portfolios from Self-owned Automotive-qualified 8-inch Sensor Fab

SAN JOSE, Calif. and ZHANGJIAGANG, China, July 18, 2023 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, has released several new TMR switch sensors. Highlights of these new products include dual-axis quadrature-waveform TMR1222/TMR1228 bipolar switches for flow meters and rotary encoders, TMR1367 1.2V ultra-low voltage nanoAmpere wake-up switch for battery-powered portable medical devices, new additions to the 200nanoAmpere omnipolar series TMR1363/TMR1365, and TMR1148/TMR1348 series for automotive level-sensing applications.

MDT's TMR switch sensors are equipped with advanced features of ultra-low power consumption, high sensitivity, and high-speed operation. They include the always-active series operating at 1.5microAmpere current consumption, and the 200nanoAmpere series with 50Hz power cycling. Furthermore, they support flexible configurations including unipolar/bipolar/omnipolar functionality, CMOS/ open-drain output, 1.8~5.5V or 3~40V in supply voltage, and factory-preset switching sensitivities in the programmable TMR13Dx series to meet various application requirements.

Empowered by its state-of-the-art 8-inch fab in full production with IATF-16949 qualification, MDT continues to reinforce its position as a leading manufacturer of magnetic sensors. MDT's new products will all benefit from the process upgrades targeting automotive applications, with higher performance and improved cost-effectiveness. MDT is fully committed to closely working with customers, ensuring accelerated time-to-market and offering an extensive range of magnetic sensing solutions to meet their growing needs.
