Melexis' proprietary Triaxis technology, a 16-bit resolution MLX90393 sensor IC which is on each EVB, has the capacity to deliver a digital output proportional to the detected magnetic flux density along 3 perpendicular axes (X, Y and Z). In addition, there is also provision for thermal measurement.
The IC is able to act like a building block for position sensing systems in a broad spectrum of applications. It presents engineers with a wide array of configurable parameters, allowing them to optimise their system for either high speed measurement, elevated signal integrity or low power consumption.
Both SPI and I2C interfaces are featured on the EVB, making it straightforward to integrate with an external microcontroller. There is also a pad incorporated onto the board for the connection of a decoupling capacitor if required, as well as pads for optional pull-up and pull-down resistors for I2C addressing and bus line supply. An operational temperature range spanning from -20°C to +85°C is also supported.
The EVB is supplied with a MLX90393 IC soldered directly on to the PCB, along with 3 extra ICs to accompany it. A QR code link printed on the underside of the board permits immediate access to all the relevant documentation available on the Melexis website.
