Crocus Technology releases high resolution, isolated, contact current sensor

KUALA LUMPUR, Aug 3 -- Crocus Technology Inc, the disruptive Tunnel Magneto-Resistance XtremeSense™ TMR sensors supplier, has announced 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, offering design simplicity, reduced circuit complexity and inherent isolation.

The CT110 is a coreless device which utilises 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 per cent typical total output error.

According to a statement, 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,” said Crocus Technology President and Chief Executive Officer, Zack Deiri.

“The CT110 is ideal for any application which requires current monitoring including those currently utilising 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 x 3.00 x 0.95 mm. Samples and evaluation boards are currently available, and the device will be in production in September.
