Crocus Technology announced the CT110, a high resolution, isolated, contact current sensor based on Crocus’ TMR technology. The CT110 provides highly accurate current measurements over a wide operating temperature range in a miniature form-factor.

The CT110 is a coreless device which utilizes Crocus’s 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.

Samples and evaluation boards are currently available, and the device will be in production in September 2020
