MLX90392 3D Magnetometer

Melexis' MLX90392 is a monolithic sensor IC that is sensitive to the flux density applied orthogonally and parallel to the IC surface. The device makes magnetic measurements along the three-axis (X, Y being in a plane parallel to the surface of the die, Z being perpendicular to the surface). Those measurements and the IC temperature are converted into 16-bit words which are transferred upon request over an I²C communication channel. The device transmits compensated raw measurement data.

Specially designed for low-micropower applications, the MLX90392 features a power-down current of 1.5 µA and operates on a 1.8 V supply.

MLX90392 Simplifies Designs

The MLX90392 magnetometer reduces bill-of-materials costs and saves PCB space. Measuring just 2 mm x 2.5 mm x 0.4 mm, the sensor features a UTDFN-8 ultra-thin flat no-lead 8-pin package to help designers tackle space-constrained applications. The MLX90392's internal parameter can be updated on the fly from the microcontroller I²C bus, eliminating the need for an extra pin. Simpler PCBs can be achieved.

The MLX90392 comes pre-programmed, making it a plug-and-play solution to integrate.

The MLX90392 is available in two magnetic versions:

• ±5 mT range for low-noise applications
• ±50 mT range for position-sensor applications
