IXYS Introduces a 12-Bit Digital Magnetic Flux Sensor

SANTA CLARA, CA /BUSINESS WIRE/ -- IXYS Corp. announced that its Clare Micronix division has developed a new 12-bit digital output magnetic flux sensor, the MX868. The sensor is a complete sampled data subsystem that includes a unique adjustable digital filter that significantly improves signal to noise performance while also reducing signal bandwidth. The MX868 is powered from a 4.5-5.5 volt supply and converts a magnetic flux intensity of +/- 500 Gauss full scale into a 12-bit digital output word. It operates as a slave on a standard serial interface bus and is compatible with daisy chain expansion in a multiple device serial bus configuration. The MX868 can be mounted onto a PCB or incorporated into a magnetic assembly and then calibrated in-system through the serial interface.

This integrated circuit is designed to sense the magnetic field generated in power systems as a result of electrical current, as well as in motor control applications. Designers can use the IC for sensing of electrical current, and thus sense power level, with digital signal output to facilitate digital power control.

"The MX868 takes our hall sensor technology to the next level of system integration. We have combined our sensitive magnetic flux sensor and signal processing technologies to enable precise monitoring of high-amperage DC motors. The MX868 is the first device in a new family of hall sensors that will be introduced over the next year," remarked Bob DeCaro, vice president and general manager of Clare Micronix. "We are offering application support and information on the versatility of the MX868 that can reduce system costs by using our IC versus expensive current sensors or other magnetic analog sensors."
