Crocus Technology Unleashes the World’s Fastest and Most Ac-curate XtremeSense® TMR Current Sensor with No Performance Compromises

Crocus Technology Inc., the leading supplier of disruptive Tunnel Magneto-Resistance XtremeSense™ TMR sensors, today announces the CT430 and CT431 isolated current sensor with 1MHz bandwidth and <1% total error over the full temperature range. The high speed operation and accurate output allow customers to optimize system design for smaller size and higher efficiency. In contrast to existing designs that utilize a Hall Sensor, the XtremeSense™ TMR sensor enables a no-compromise design solution by combining high bandwidth response and high accuracy.

The CT43x products are coreless devices which utilize Crocus’ state-of-the-art XtremeSense™ TMR technology to detect extremely small variations in AC or DC currents while achieving an unprecedented total output error of less than ±1.0% over the full temperature range from -40°C to +125°C. In addition, the CT43x has robust built-in immunity to common-mode fields which allows the device to reject > 99% of stray fields without the need for external shielding. The Crocus proprietary TMR technology inherently offers very high signal-to-noise ratio (SNR) which allow for high resolution measurements required for precision control or monitoring applications. The linear error and offset performance is intrinsically more accurate permitting the elimination of system level calibration normally done with an external voltage reference, thus freeing up processor time and simplifying system design. “I’m excited to introduce this truly differentiated current sensor product which highlights the benefits the Crocus XtremeSense™ TMR technology can bring.” states Zack Deiri, President and CEO of Crocus Technology. “Our customers have been astounded by the level of performance we are able to deliver in their applications. The combination of high response time and accuracy provides system designers the flexibility they have been eager to achieve without any compromises.”

Product features and performance:

  • CT430 (5 V version), CT431 (3.3 V version)
  • Integrated 0.5 mΩ conductor enabling 20 A, 30 A and 50 A applications
  • Total error output +/-0.7% (typ)
  • 300ns response time, 1-MHz bandwidth
  • Low noise 9 mArms
  • Integrated Common Mode Field Rejection (CMFR) with > 99% immunity
  • Over-Current Detection output pin

Investments made last year to expand our production capacity has enabled Crocus to be prepared to support high volume production today. To date we have shipped over 50M XtremeSense™ TMR sensors, and our customer base continues to rapidly expand. Products like the CT430 and CT431 which have an industry standard footprint enable customers to easily upgrade their existing products and accelerate product adoption.

Targeting applications in Solar Power Inverters, Power-Factor Correction (PFC), Battery Management Systems (BMS), Smart Appliances, IoT, and Power Supplies applications. These state-of-the-art devices are perfect companions to emerging applications utilizing GaN and SiC power devices where the fast response time of the Crocus TMR current sensors will ensure the highest operational efficiency.
