Description The MLX90395 Triaxis Magnetic Node is a miniature monolithic sensor IC sensitive to the three orthogonal components of the flux density applied to the IC (i.e. BX, BY and BZ) and to temperature. This allows the MLX90395 with the correct magnetic circuit to decode the absolute position of any moving magnet. It enables the design of novel generation of non-contacting position sensors that are frequently required for both automotive and industrial applications. The MLX90395 selectable measurement data can be read over I2C or SPI bus. The sensor is runtime programmable and offers on-chip temperature compensation of the measured units. The selectable measurement duty cycle enables unsurpassed micro-power functionality. In this respect, the MLX90395 is the first true Software Defined Sensor: one IC, any magnetic sensing application. You define the function. MLX90395 Triaxis® Magnetometer Node Datasheet 4. Ordering Information Note: Ordering code BAA-x0x: not recommended for new designs.

Functional Diagram The MLX90395 is sensitive to the three (BX, BY, BZ) components of the flux density applied to the IC. This allows the MLX90395 with the correct off-chip signal processing to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees, linear displacement, joystick… as shown in Figure 1). The flexibility resides in the runtime selection of measurement data and the application software in the external microcontroller, resulting in a true “Software-Defined Magnetic Sensor”. Rotary End-of-Shaft (with Push) Linear Axial Parallel Ball & Socket Joystick Rotary Through-Shaft Linear Axial Orthogonal Gimbal Joystick Figure 1: Magnetic Applications As the MLX90395 has no on-board microcontroller, it lends itself well to applications requiring a concatenation of multiple sensors on the communication bus of a single microcontroller, allowing more cost-efficient and lean designs. Melexis’ Applications Engineers can support in the microcontroller computations.
