SANTA CLARA, Calif., March 20 (Bernama-GLOBE NEWSWIRE) — Crocus Technology Inc., a leading supplier of disruptive Tunnel Magneto-Resistance (TMR) sensors, today announces the CT100 device, an advanced, high-performance linear (1D) magnetic sensor based on Crocus’ patented and unique TMR-based technology. The CT100 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 CT100 outperforms competitors’ xMR or Hall-based linear magnetic sensor technology available today in terms of performance, deviation over temperature, current consumption, and overall robustness. The CT100 does not require any expensive flux guides or concentrators, chopping circuits or set/reset pulses and operates over a wide magnetic field range.
Crocus’s revolutionary 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 robust 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) which does not exceed 3 µV/V/°C across a supply voltage range from 1.0 V to 5.5 V.
