Introduction

The MLX90393ELW-ABA-014-SP is a linear, compass IC (integrated circuit) from Melexis that is used for magnetic sensing. Magnetic sensing is an important element within many high-performance electronics applications; such as field strength measurements, accurate navigation, and disturbance detection. This IC is a sophisticated device that provides highly accurate measurements of magnetic fields in both the linear x- and y-axes, as well as the heading (z-axis).

Application Field

The MLX90393ELW-ABA-014-SP IC is ideal for applications that require precise linear and/or compass data in one device. Examples include automotive navigation systems, security/surveillance sensors, medical monitoring and diagnostic tools, and consumer electronics. Sectors that may benefit from this IC include aviation, robotics, manufacturing, and power engineering.

In addition, this device is designed to reliably operate in challenging environments with electrically noisy conditions. Therefore, it can be used for applications within industrial automation and refining. It could also potentially be used for navigating hazardous terrains in search and rescue operations. Therefore, versatility and reliability are two of its main advantages.

Working Principle

The MLX90393ELW-ABA-014-SP IC uses an internal linear digital Hall-effect array that measures magnetic field density in both the x- and y-axes. This array is based on the push-pull technique, which involves two emitters placed opposite each other in the array, thus providing an opposite but equal output. The device also includes a rotatable internal structure and a reference coil to ensure maximum accuracy of the measurements.

In addition, the device features an integrated digital signal processor (DSP) programmed with algorithms specifically designed to optimize magnetic field measurement accuracy and reliability. This DSP is capable of compensating for external factors that may affect the linear/compass measurements, such as temperature, external magnetic field drift, and offset. It can also be used for self-calibration purposes.

Furthermore, this device also contains various other functions such as power down and wakeup, temperature sensor, proxomity detection, three-axis compass offset and full-scale current output, all designed to further enhance the accuracy and reliability of the measurements.

Conclusion

The MLX90393ELW-ABA-014-SP IC from Melexis is a highly advanced linear, compass IC with several features that allow for reliable and accurate measurements in a wide variety of applications. This device can be used for automotive navigation systems, security/surveillance sensors, medical monitoring and diagnostic tools, and consumer electronics. It is also designed to reliably operate in electrically noisy conditions, making it suitable for industrial automation and refining. Finally, it features an integrated digital signal processor and various other functions designed to maximize accuracy and reliability.
