What Crocus Technology does
Crocus Technology is a Santa Clara, California-based semiconductor company founded in 2004 that specialized in Tunneling Magnetoresistance (TMR) and Magnetic Tunnel Junction (MTJ) technology for magnetic sensing applications. Its core technology is built on thin-film magneto-resistive MTJ devices that deliver higher magnetic sensitivity, lower power consumption, and smaller form factors than incumbent Hall, AMR, and GMR magnetic sensing technologies, while supporting wide-bandgap (GaN and SiC) power-conversion designs that require high bandwidth and accuracy.
The company's XtremeSense TMR product portfolio spans three core families: high-linearity current sensors for 0 to >1000A applications (CT220, CT455, CT456, and the CT41x/CT42x/CT43x series with sub-0.7% total error), 1D/2D linear and angular position sensors (CT100, CT310, CT8150, CT8152), and integrated micropower switches and latches (CT8111/CT8112/CT8122/CT8131/CT8132). These products serve automotive (primary segment, including xEV, ADAS, and power conversion), industrial (automation, robotics, motor control), and consumer electronics applications. Crocus generated revenue via technology/IP licensing and sensor product sales to OEMs and tier-one suppliers across these verticals.
Crocus raised approximately USD 143 million across six funding rounds from 2006 to 2018 from a syndicate including Sofinnova, Idinvest Partners, CEA Investissement, +ND Capital, Ventech, RUSNANO, and CDC Enterprises. In 2025-2026, the company was acquired by Allegro MicroSystems for USD 420 million, integrating its TMR technology and XtremeSense product line into Allegro's broader magnetic sensing franchise. Leadership includes Zack Deiri as Chief Executive Officer, Jacques Noels as Founder, and Michel Desbard as Executive Chairman.
