1 Functional Diagram
2 General Description
The Triais® rotary position sensor MLX91204
detects the absolute angular position of a small
magnet that is positioned above the device
surface.
The MLX91204 reports two analog, linear,
orthogonal (quadrature) and ratiometric
output voltages proportional to the applied
magnetic flux density parallel to the chip
surface (thanks to the Integrated Magneto
Concentrator – IMC® – added on the top of
the sensitive Hall elements).
The MLX91204 is ideally suited for hi-speed
rotary position sensing in harsh automotive
and industrial environments.
The angular position is computed off-chip
from both sine and cosine signals.
