Crocus Technology
Crocus Technology develops and supplies magnetic sensors based on its revolutionary and patented XtremeSense® TMR technology. Crocus’ TMR sensor products take advantage of monolithic technology enabling the magnetic sensor to be fully integrated on top of a proprietary CMOS lithography process which in turn simplifies the manufacturing flow and achieves higher levels of integration and performance metrics.
These Crocus TMR sensors have high sensitivity and low noise plus nano-level low power consumption and offer high reliability and stable magnetic performance over temperature and outstanding robustness under extreme operating environments. These TMR sensors are an ideal sensing solution for IoT, consumer electronics and industrial applications.
The Crocus magnetic sensor family includes integrated magnetic switches and discrete current sensors, all based on XtremeSense® TMR technology, which provides the highest sensitivity, lowest power consumption, and highest performance among other magnetic technologies (Hall effect, AMR, GMR).
Tunnel Magneto-Resistance (TMR) Technology
Crocus Technology developed its innovative and patented XtremeSense® TMR technology to provide superior magnetic sensing performance for use in many applications.
The XtremeSense® TMR technology enables high magnetic sensitivity, stable performance over temperature, low noise and low power consumption which allows it be used in a wide variety of end-products and markets.
At the heart of XtremeSense® TMR technology is a thin film magneto-resistive device, the so-called Magnetic Tunnel Junction (MTJ). In its simplest form the MTJ consists of two magnetic layers on both sides of a thin insulating layer. One layer has a fixed magnetic moment while the other can chance freely in the presence of a magnetic field.
When a magnetic field aligns with direction of the fixed layer, resistance is low. Resistance increases when applied field deviates from fixed layer direction. This change in resistance is the principle behind XtremeSense’s® high performance sensor technology.
XtremeSense® TMR provides the highest sensitivity, the lowest power consumption, and smallest size by comparison to the other magnetic technologies such as Hall, AMR, and GMR.
