Magnetic sensors are commonly used in various different applications such as magnetic navigation, closed-loop control, robotic/vision systems, security systems and more. They make use of a wide range of technologies such as Hall Effect, anisotropic magnetoresistance (AMR) and giant magnetoresistance (GMR). The MLX90215LVA-AAA-111-SP is a ferromagnetic field sensor which belongs to the family of linear, compass (ICs).

Applications

The MLX90215LVA-AAA-111-SP is a magnetically sensitive IC that is particularly suitable for automotive and industrial applications. It is designed to detect the magnetic field in three axes and to provide an analog output to an external microcontroller for further processing. Some of the applications of this type of IC include automotive navigation systems, motor control, magnetic positioning systems, angle measurements, and consumer applications such as local positioning systems and location-based services.

Working Principle

The MLX90215LVA-AAA-111-SP is composed of an integrated Hall Effect-type magnetoresistor connected to an amplifier. The magnetoresistor works as a transducer to convert the strength of the external magnetic field into a voltage or current signal. When an external magnetic field is applied to the magnetoresistor, the resistance of the magnetoresistor changes, which causes it to interact with the amplifier, resulting in an output that is proportional to the strength of the magnetic field. The MLX90215LVA-AAA-111-SP provides two outputs: one for X-axis and one for Y-axis. The intensity in each axis is determined by the amount of external magnetic field present, the sensitivity of the magnetoresistor and the amplification of the amplifier.

The MLX90215LVA-AAA-111-SP is also designed to be immune to external noise sources such as other magnets, electric fields, and temperature changes. A special feature of this IC is the protection against ESD. This feature helps protect
