MLX90316 and MLX90333
Hall Position Sensors
The MLX90316 is a monolithic sensor
IC featuring the Triaxis™ Hall technology. Conventional
planar Hall technology is only sensitive to the flux
density applied orthogonally to the IC surface. The
Triaxis™ 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 3). 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.
The MLX90333 is the 3D-variation of the MLX90313 and is used in applications
for joysticks and linear position measurement.
