The CT300 is a 2D magnetic sensor with an angular error well below 0.5°
Crocus Technology announces the CT300 device, a new break-through TMR-based angular (2D) magnetic sensor with an extremely low angular error and high stability over a wide temperature and voltage ranges to address a variety of markets.
The CT300 is designed using Crocus’s revolutionary Magnetic Logic Unit™ (MLU™) technology and consists of two full-bridge magnetic resistor networks capable of two-dimensional sensing. In the presence of a rotating magnetic field, the CT300 senses the field and produces two sets of differential signals representing the sine (SIN) and cosine (COS) waveforms. Once the differential signals of the CT300 are processed and compensated, the resulting angular error will be at or below 0.5° over a temperature range of –40 °C to +150 °C. A single CT300 can measure the absolute angle resulting from a full 360° rotation and can sense magnetic fields ranging from 20 mT to 80 mT.

The CT300 addresses the demands of the consumer, industrial, medical and automotive markets and is highly suited for applications such as OIS (Optical Image Stabilization)/AF (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.
CT300 is available in wafer/KGD (Known-Good-Die), an 8-lead TSSOP package, and in an ultra-low profile and small form factor 8-lead DFN package. Samples will be available in December 2018 and fully qualified for production in the first quarter (Q1) of 2019.
