New TMR Sensor Series Offers Excellent Temperature Stability and Versatility, Enabling Wideband Current Sensing Solutions for High-speed Power Electronics

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 -40~125 °C.
• Two versions with native linear range in ±1000 Gauss (TMR2651D) and ±500 Gauss (TMR2652D).
• Two supply voltage settings in 5.0V and 3.3V.
• Excellent linearity and low hysteresis.
• User-performed in-field calibration through the optional programming toolkit.
• Compact 3*2*0.75mm DFN6L package.

The TMR265x sensors are immediately available to order from Digi-key at competitive pricing, making them suitable for general-purpose magnetic field measurement for a wide variety of sensor applications.
