Magnetic sensors are essential components for a broad range of consumer electronics, industrial control, and medical devices. The MLX90215LVA-LC03 is multifunctional magnetic sensor IC from Melexis. It offers board-level magnetic field sensing for rotational and hinge applications. It provides system developers the flexibility to sense relative position and movements of mechanical structures with precision and accuracy.

Application Field

The MLX90215LVA-LC03 is a surface mountable device, designed for measurement and computation of an magnetic field. It can be used to detect movement of parts such as rotational control knobs and remote control systems, providing precise data on movement movement and direction. The sensor can also be used for guidance systems such as toy robots or drones, motion detection for security systems, and safety applications such as door or window open/close detection.

Working Principle

The MLX90215LVA-LC03 is an integrated Hall effect device. The device utilizes the Hall effect to measure the linear, rotational, and direction changes of a magnetic field. It features an integrated magnetic flux concentrator with a high sensitivity of 50mV/T, and can detect magnetic fields in the range of +/- 200mT in the Z-axis. The integrated temperature compensation ensures that the sensor output is reliable over temperature variations. It has a low power consumption of 6.2mW at 3.3V, making it ideal for battery operated applications.
