MLX90316 DataSheet
The datasheet provides more technical information on the MLX90316 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 MLX90316 is only sensitive to the flux density coplanar with the IC surface. This allows the
MLX90316 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 4). The
angular information is computed from both vectorial components of the flux density (i.e. BX and BY).
MLX90316 produces an output signal proportional to the decoded angle. The output is selectable between
Analog, PWM and Serial Protocol.
