MagnaChip Semiconductor Corporation's new digital Hall sensor product line, the MXM1120 series, is designed to replace conventional analog Hall switches in emerging consumer, industrial, and medical magnetic sensor applications. 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.


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.

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