CT815x

Digital TMR Latch​

Integrated Omnipolar TMR Analog Sensor

The CT815x series of Tunnel Magnetoresistance (TMR) analog sensors (with option for digital latch output) are designed for consumer and industrial applications. It is based on Crocus Technology’s patented Magnetic Logic Unit™ (MLU™) technology with integrated CMOS process to provide a monolithic solution for superior sensing performance. Also, the CT815x analog sensors with XtremeSense® performance where it offers stable magnetic operation over temperature.

For applications that require a very small form factor and low profile, the CT815x sensors are assembled in a 4-lead LGA package. The CT8150 is also available in an industry standard 3-lead SOT-23 package while CT8152 is offered in a 5-lead SOT23 package to support high volume manufacturing.
