Crocus Technology Unveils High Linearity, High Resolution,
Integrated XtremeSense™ TMR Current Sensor
The CT110 a plug-and-play device for current monitoring applications requiring high linearity,
high resolution, miniature form-factor, isolation, and design simplicity
Santa Clara, California, July 30, 2020 – Crocus Technology Inc., the leading supplier of disruptive Tunnel Magneto-
Resistance XtremeSense™ TMR sensors, today announces the CT110, a high resolution, isolated, contact current
sensor based on Crocus’ patented and unique TMR technology. The CT110 provides highly accurate current
measurements over a wide operating temperature range in a miniature form-factor. The CT110 offers design simplicity,
reduced circuit complexity, and inherent isolation.
The CT110 is a coreless device which utilizes Crocus’s state-of-the-art XtremeSense TMR 1D technology to accurately
detect the smallest variation in AC or DC current while achieving a class-leading less than 0.5% typical total output
error. Crocus offers the CT110 in configurations which support 5 A to 15 A with the ability to detect less than 5 mA
variations in current due to its low-noise and high sensitivity capabilities compared to traditional Hall sensor
technologies, which require flux guiding, significant signal amplification, and temperature compensation. The CT110 is
a ratio-metric device with an analog output capable of operating from 2.7 V to 5.5 V at 200 kHz sampling frequency
and low power consumption.
“The CT110 demonstrates the advancement Crocus has achieved in TMR magnetic sensing technology. The CT110
offers a robust sensing resolution, stable performance over temperature combined with design simplicity. Crocus’s
XtremeSense TMR 1D technology offers an extremely low noise, high sensitivity, high linearity, low temperature drift,
and virtually no hysteresis which renders existing sensing technologies obsolete. The CT110 is one of a family of
devices Crocus will introduce this year which target power monitoring applications. The CT110 is a perfect current
sensor for consumer, enterprise, and industrial applications. Due to its small form-factor and high resolution, the CT110
is suitable for applications such as smart plugs and IoT devices, appliances, drones, LED lighting, battery chargers,
power tools, and PCs and servers,” states Zack Deiri, President and CEO of Crocus Technology. “The CT110 is ideal
for any application which requires current monitoring including those currently utilizing shunt resistors combined with
an isolation amplifier. To simplify and expedite customer’s system evaluation, Crocus offers evaluation boards with
multiple current sensing configurations.”
The CT110 is available in a low profile and small form factor 6-lead DFN package with dimensions of 3.00 × 3.00 ×
0.95 mm. Samples and evaluation boards are currently available, and the device will be in production in September
2020. For more information on the CT110, please visit the product webpage at
