The CT100, says the company, has best-in-class performance across a wide temperature range coupled with an extremely low linearity error, low hysteresis, and low noise, which enables it to address many consumer, industrial and automotive applications and markets. The device is claimed to outperform xMR or Hall-based linear magnetic sensor technologies available today in terms of performance, deviation over temperature, current consumption, and overall robustness.

“The CT100 with its high frequency response, minimal power consumption and small form factor, enables simple and creative system designs in applications such as IoT, drones, electric motor controls, power monitoring, and many other consumer, industrial and automotive applications,” says Zack Deiri, CEO of Crocus Technology. “Many applications today demand performance but not at the expense of large deviations due to temperature fluctuation which impacts system performance and safety. The CT100, a discrete TMR sensor with ESD protection, offers superior performance to our competitors’ fully integrated and highly compensated solutions in terms of accuracy and robustness over field and temperature.”

The company’s Magnetic Logic Unit (MLU) TMR technology is implemented into the CT100 with a single full-bridge magnetic resistor network, which delivers high gain and high accuracy. The CT100 senses the presence of a magnetic field (whether from a magnet or a field generated by a current carrying conductor) and outputs a differential signal with a linearity error that is less than ±0.5% over a magnetic field range from -20 mT to +20 mT with negligible hysteresis and extremely low noise.

The device operates from -40°C to +150°C and yields a predictable temperature coefficient of sensitivity (TCS) of less than 300 ppm/°C and a temperature coefficient of offset (TCO) that does not exceed 3 µV/V/°C across a supply voltage range from 1.0 V to 5.5 V.

The CT100 is available in a 6-lead SOT23 package, and in an ultra-low profile and small form factor 6-lead DFN package, as well as wafer/KGD (Known-Good-Die). Samples and evaluation boards are currently available, and production is targeted for early Q3 2019.
