The MLX90392 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface. The device makes magnetic measurement along the 3 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 I2C communication channel. The device transmits compensated raw measurement data.

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

• Ambient temperature range from -40℃C to 85℃

To begin with, it 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. To continue, the MLX90392 internal parameter can be updated on the fly from the microcontroller I2C bus, thus eliminating the need for an extra pin. Simpler PCB can be achieved.

And finally, the MLX90392 comes pre-programmed, making it a plug & play solution to integrate.

The MLX90392 is available in 2 magnetic versions:
+/-5mT range for low-noise applications
+/-50mT range for position sensor applications
