Magnachip Introduces the MagnachipM1120 Digital Hall Sensor for Magnetic Sensor Applications

New Digital Hall Sensor Replaces Conventional Analog Sensors with Flexible Programmable Options for Wide-Ranging Design Flexibility


SEOUL, South Korea and CUPERTINO, Calif., July 25, 2013 /PRNewswire/ —

Featured Highlights:

New digital Hall sensor features 10-bit ADC (analog-digital converter) and programmable functionality for design flexibility
Applicable for consumer, automotive, industrial and medical products
Broad range of software, hardware and OEM partner support

MagnaChip Semiconductor Corporation (“MagnaChip”) (NYSE: MX), a Korean semiconductor company with a broad portfolio of analog and mixed-signal products and technologies, today announced a new digital Hall sensor product line designed for emerging consumer, industrial and medical magnetic sensor applications. This line replaces conventional analog Hall switches. The MXM1120 series uses MagnaChip’s 0.18 micron low noise mixed-signal technology and proprietary Hall technology. The development kit is available for multiple operating systems including Android OS.

More computing products, applications, and systems are moving towards digital based solutions challenging the limits of conventional analog-based functions. This mega-trend demands digitally-controllable parts, especially smart sensors for all digital interface and seamless signal processing without conversion loss.

The MXM1120 series deliver I2C digital interface and fully-digitized functionality with a 10-bit ADC and an embedded logic controller. Compatible with wake-up schemes, the MXM1120 series features an additional interrupt output allowing programmable Brp and Bop parameters. These universal features provide the benefit of easy porting to any particular system allowing engineers to quickly implement value-added functions through programming. For example, flip-covers of handheld devices require a magnetic sensor that can solve both the high deviation in quality as a result of production anomalies of magnets as well as malfunctions caused by unintended cover opening. MagnaChip’s self-calibration programming can ignore the magnet flux deviations, while 10-bit magnetic field measurement can reject unintended malfunctions with signal processing techniques.

“Our new MXM1120 Hall sensor provides flexible programming capabilities and other competitive features that will allow us to expand into the new and growing business opportunity of digitized smart applications,” said YJ Kim, Executive Vice President and General Manager of MagnaChip’s Display Solutions Division. “MagnaChip will continue to provide the consumer with innovative new products such as application-specific Hall sensors that will service the demand for leading-edge applications and product features.

Pricing and Availability
MXM1120 Hall sensor is currently being sampled and will go to production in Q3 2013. Evaluation kit is available through MagnaChip sales channels.
