Crocus Technology Unveils Second Generation TMR Sensor Using Its Disruptive Magnetic
Logic Unit
Crocus Technology, a developer of disruptive tunnel magnetoresistance (TMR) sensors, has recently introduced another device based upon its patented Magnetic Logic Unit, this one employing
the company's second generation TMR technology.
The new CT100 is an advanced linear magnetic sensor that can measure the current from an induced magnetic field of a current carrying conductor. It follows the company's earlier introduction of
a two-dimensional angular sensor in late 2018, the CT300.
Able to perform across a wide temperature range with an extremely low linearity error, low hysteresis, and low noise, the new device can address many consumer, industrial and automotive applications, says the company. It does not require flux guides or concentrators, chopping circuits or set/reset pulses and operates over a
wide magnetic field range. The MLU is integrated
into the CT100 with a single full-bridge magnetic
resistor network.
"With its high frequency response, minimal power
consumption and small form factor, the CT100 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," according to Zack Deiri, CEO of Crocus.

current monitors, IoT smart devices,
electric motors, magnetic card readers, window and door sensors and mobile electronics where excellent linearity performance and
thermal stability is a must."

Crocus also
makes TMR
angular sensors that detect
the absolute
angular orientation of an
on-axis 2-pole
magnet rotating over the center of the sensor. In late 2018, it introduced its CT300 which is a discrete TMR-based
angular sensor also using the MLU technology and
designed to provide extremely stable magnetic
performance over a wide temperature range and
supply voltage range. It is suited for applications
such as optical image stabilization, auto-focus
enabled camera modules, optical encoders, BLDC
motor control, IoT enabled smart devices and appliances, automation equipment, industrial controls
and robotics where precise angular position measurements are required.
Headquartered in Santa Clara, CA, Crocus also
has offices in Grenoble, France where the company was founded, and in China.
