Description The MLX90324 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 MLX90324 is only sensitive to the flux density coplanar with the IC surface. This allows the MLX90324 with the correct magnetic circuit to decode the absolute rotary (angular) position from 0 to 360 Degrees. It enables the design of novel generation of non-contacting rotary position sensors that are frequently required for both automotive and industrial applications. In combination with the appropriate signal processing, the magnetic flux density of a small magnet (diametral magnetization) rotating above the IC can be measured in a non-contacting way (Figure 2). The angular information is computed from both vectorial components of the flux density (i.e. B and B ). X Y MLX90324 produces an output signal proportional to the decoded angle. The output is selectable between Analog, PWM and SENT (SAE-J2716) Protocol. Figure 2 - Typical application of MLX90324 The MLX90324 is similar to the MLX90316 in many ways but it is targeted for Under-the-Hood applications and the associated harsh hi-temperature environment. Amongst others, the hi-temperature performances and the SENT feature confirm this devotion. 3901090324 Page 2 of 41 Data Sheet Rev. 005 May 17 14-15 12
