Description

The MLX90333 is a monolithic sensor IC featuring the Tria?is? Hall technology. Conventional planar Hall technology is only sensitive to the flux density applied orthogonally to the IC surface. The Tria?is? Hall sensor is also sensitive to the flux density applied parallel to the IC surface. This is obtained through an Integrated Magneto-Concentrator (IMC?) which is deposited on the CMOS die (as an additional back-end step).

The MLX90333 is sensitive to the 3 components of the flux density applied to the IC (BX, BY and BZ). This allows the MLX90333 to sense any magnet moving in its surrounding and it enables the design of novel generation of non-contacting joystick position sensors which are often required for both automotive and industrial applications (e.g. man-machine interface).
