MultiDimension Debuts TMR Linear Magnetic Field Sensors

December 14, 2011

New tunneling magnetoresistance (TMR) sensors offer large dynamic range, superior performance and low power in a wide spectrum of industrial and consumer sensor applications.


SAN JOSE, CA and ZHANGJIAGANG, Jiangsu, China, -- /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, has announced a lineup of three linear magnetic field sensors, MMLD47F, MMLP57F and MMLP57H. They are the world's first magnetic field sensors setting outstanding marks in the most critical magnetic sensor design features, including a large dynamic range of ±70 Oe, ultra-low hysteresis below 0.1% of the full-scale field range, high sensitivity up to 6 mV/V/Oe, and power consumption as low as 5 µW, which have never before been realized by any magnetic field sensor. They are designed to suit a variety of industrial and consumer applications under diverse operating conditions, including magnetic field, current, and position sensing.

"MDT's new TMR linear sensors provide the best value to applications that demand large dynamic range, precision measurement, high sensitivity, and low power consumption. Backed by our strong intellectual property portfolio and advanced manufacturing facilities, we are fully capable of offering all these critical benefits in a single sensor design. This combination of benefits is unprecedented, and it is not achievable using any other existing magnetic sensor technologies, including Anisotropic Magnetoresistance (AMR), Giant Magnetoresistance (GMR), or the Hall Effect. MDT is the first high-volume manufacturer that brings the full advantages of TMR technology to the commercial sensor market," said Dr. Song Xue, Chairman and CEO of MultiDimension Technology. "With our world-class expertise in TMR technology, volume production, application engineering, and technical support, we are confident that MDT will create ground-breaking opportunities to expedite the growth of the magnetic sensor industry, which are otherwise not possible in today's market."

The MMLD47F/MMLP57F/MMLP57H sensors are available in a 6 mm x 5 mm x 1.7 mm SOP8 package and a small 3 mm x 3 mm x 0.75 mm DFN8 package for space-constrained designs. They exhibit ultra-low hysteresis below 0.1% full-scale, while operating over a wide field range of up to ±70 Oe, and they show excellent temperature stability from –40°C to 125°C. The magnetic field sensitivity is designed to be 3 to 6 mV/V/Oe, and the typical current consumption is between 5 and 12.5 µA with a 1 V voltage supply.
