Covering Disruptive Technology Powering Business in The Digital Age

MultiDimension Technology Co., Ltd. (MDT), a leading supplier of magnetic sensors specialising in Tunneling Magnetoresistance (TMR) technology, has released the TMR2623 linear magnetic field sensor with built-in programmable signal conditioning circuitry. Designed for current sensing, position sensing and other high-performance industrial magnetic sensor applications, they are factory-calibrated and temperature-compensated to customisable sensitivity and full-scale voltage output level supporting a wide measurement range up to ±500 Gauss, achieving high uniformity and temperature stability in performance metrics across production volumes with enhanced versatility for a variety of applications under diverse operating conditions.

“With the built-in programmable signal conditioning circuitry that performs calibration and temperature-compensation of the TMR sensor’s performance parameters, including offset, sensitivity, measurement range, and linearity, and the adjustable gain to customise the sensitivity and the full-scale output voltage, TMR2623 achieves outstanding device uniformity and temperature stability in performance metrics over mass production quantities, thus relieving customers’ efforts and resources that would have been spent on calibrating individual devices. This new capability is vital for high-volume, performance-critical industrial sensor applications such as current sensing, offering our customers a fast-track for time-to-market.” said Dr Song Xue, Chairman and CEO at MultiDimension Technology.

Dr Xue added: “Built on MDT’s extensive experience and unique IP portfolio in TMR sensor and ASIC design, and the in-depth understanding of application requirements by closely working with our customers, we are ready to unleash the full potentials of our TMR technology in a fully integrated and ready-to-use TMR sensor device, offering our customers enhanced return-on-investment.”

Key features of TMR2623 include:

• Excellent temperature stability in -40~125°C, with TCS (temperature-coefficient-sensitivity) under 100PPM/°C, TCO (temperature-coefficient-offset) under 50PPM/°C
• Programmable sensitivity in 1~200mV/Gauss and full-scale output voltage, corresponding to a customisable measurement range up to ±500 Gauss
• High frequency response up to 2MHz
• Two versions supporting 3.3V/5.0V supply voltage
• Compact 3*2*0.75mm DFN package
