MLX90821 web

The MLX90395 is a 3D magnetometer capable of measuring X, Y, and Z magnetic fields and is an expansion of the set of Melexis sensors offering this output. Unlike many other magnetometers, the MLX90395 is designed to sense magnetic fields produced by a permanent magnet versus earths magnetic field. Therefore, the MLX90395 is well suited to sense the position of a static or moving magnet in the vicinity of the sensor by measuring the magnetic fields produced by it.

Compared to the previously released, consumer-product-focused MLX90393, the MLX90395 shares many features but also differs in many ways.

Wider temperature range
The MLX90395 operates over a wider temperature range than the MLX90393, from -40 degC to 125 degC ambient, making the MLX90395 suitable for in-cabin, on-body, or light powertrain applications in automotive. It is also suitable for many industrial applications like factory automation, robotics, or material handling.

Higher speed operation
The speed has been increased, up to a 2kHz peak sampling rate, when measuring all three magnetic field axes.

Supply voltage measurement
The MLX90395 can also measure its own supply voltage to enable a plausibility check to be conducted with the ADC in the host microcontroller. The supply voltage measurement also enables monitoring of battery discharge in battery powered applications.
