MLX90251EVA-FAA-300-SP is a monolithic integrated linear digital Hall-effect sensor, suitable for industrial and consumer applications. The device includes an advanced patented ASIC sensor die and a linear magnetostrictive element for optimizing performance in terms of accuracy, linearity and power consumption. The device also features frequency and level conversion for superior signal-to-noise ratio and perfect detection of even the smallest magnetic field changes.

The MLX90251EVA-FAA-300-SP is widely used for non-contact proximity and motion sensing applications such as speed measurement, position detection, and small-range magnetometry applications in automotive, industrial, and machine-to-machine (M2M) systems. It is an ideal choice for uncompromised measurement, registration, and processing of ferromagnetic signals. This device is also used for applications in communication infrastructure, including RFID, GSM/GPRS, and cellular base stations.

The MLX90251EVA-FAA-300-SP application field and working principle can be classified into magnetic sensors in Linear, Compass (ICs). In terms of working principles, magnetic sensors measure the magnitude and direction of the external magnetic field and convert the signals into electrical signals that can be read by the system controlling the device. The linear and compass operation mode of the MLX90251EVA-FAA-300-SP convert magnetic signals into electrical signals in proportion to the strength of the magnetic field.

The MLX90251EVA-FAA-300-SP contains a hall effect chip integrated onto the die. The hall effect chip senses the magnetic field and its strength. It then produces a small voltage which can be used to detect the direction and magnitude of the magnetic field. The hall effect sensor is amplifying the magnetic signal and allows for more efficient reading and retrieving of the magnetic and linear signals.

The compass feature of the MLX90251EVA-FAA-300-SP uses advanced circuitry and filtering techniques for better performance while the linear features guarantee linearity over the entire range of the linear input magnetic field. The magnetic field is measured along three perpendicular axis. Each axis has an amplifier stage which measures the magnetic field along its direction. The difference between the outputs of the three amplifiers is then analyzed and a polarity signal is generated for sensing the direction of the field.

The MLX90251EVA-FAA-300-SP has an integrated microprocessor which can perform the calculations necessary for the correct functioning of the device. It can calculate the relative direction and can also calculate the average value of the signals from the three axes. The device can also detect the fluctuations in the magnetic field strength, for example when a circuit is passing in front of the sensor and the signal fluctuates accordingly.

The MLX90251EVA-FAA-300-SP is also equipped with an I2C/TWI interface that allows the device to be connected to other systems. The I2C/TWI interface is used to communicate with other systems, allowing the device to be integrated into larger systems. The device also includes a programmable FIFO (First In – First Out) memory that can store the signals from the measurement measure up to 8 magnetic field measurements.

In conclusion, the MLX90251EVA-FAA-300-SP is a highly capable magnetic sensor for linear, compass (ICs) applications. It is Small-Size, Low-Power and Highly Accurate device that can be used for a variety of applications in automotive, industrial, and machine-to-machine (M2M) systems. Its advanced features and integrated microprocessor provide great performance and make it an ideal choice for any linear or compass application.
