MDT Launches TMR265x Programmable TMR Linear Sensors with 2MHz Bandwidth for Current Sensing

NUREMBERG, Germany and ZHANGJIAGANG, China, May 9, 2023 /PRNewswire/ -- MultiDimension Technology Co., Ltd. (MDT), a leading manufacturer of magnetic sensors specializing in Tunneling Magnetoresistance (TMR) technology, has introduced the TMR265x linear magnetic field sensors at Sensor+Test 2023. Designed to provide wideband current sensing for high-speed power electronics, these sensors feature a 2MHz bandwidth, and they are equipped with a built-in programmable signal conditioning ASIC that supports temperature-calibrated customization of sensitivity and measurement range up to ±1000 Gauss. Through factory presetting or user-performed in-field programming, they offer high uniformity and temperature stability of critical performance metrics for a variety of high-frequency and high-precision sensor applications, including current sensing, rotary encoders, and non-destructive testing.

The TMR265x series sets a new standard with the highest frequency response of 2MHz among all signal-conditioned magnetic field and current sensing ICs on the market, making it ideal for current monitoring in high-speed power electronics such as silicon-carbide (SiC) / gallium-nitride (GaN) power switches. The programmable signal conditioning ASIC supports enhanced versatility in optimizing the critical performance parameters toward specific application requirements. The user-programmable option provides a flexible and efficient way to explore various design choices from concept to production. The enriched feature set of TMR265x enables customers to accelerate their development cycle and time-to-market for high-volume, performance-critical sensor applications.

Key features and benefits of TMR265x include:

  • Wide bandwidth from DC to 2MHz.
  • Programmable linear range up to ±1000 Gauss with customizable sensitivity, supporting wide current measurement ranges.
  • Multi-point temperature compensation, achieving excellent temperature stability in -40°C to 125°C.
  • Two versions with native linear range in ±1000 Gauss (TMR2651D) and ±500 Gauss (TMR2652D).
  • Two supply voltage settings in 5.0 V and 3.3 V.
  • Excellent linearity and low hysteresis.
  • User-performed in-field calibration through the optional programming toolkit.
  • Compact DFN6L (3mm × 2mm × 0.75 mm) package.
