Description
The MLX90365 is a monolithic sensor IC sensitive
to the flux density applied orthogonally and
parallel to the IC surface.
The MLX90365 is sensitive to the three
components of the flux density applied to the IC
(i.e. B
X
, B
Y
and B
Z
). This allows the MLX90365 with
the correct magnetic circuit to decode the
absolute position of any moving magnet (e.g.
rotary position from 0 to 360 Degrees or linear
displacement, stroke). It enables the design of
novel generation of non-contacting position
sensors that are frequently required for both
automotive and industrial applications.
MLX90365 reports a programmable ratiometric
analog output signal compatible with any resistive
potentiometer or programmable linear Hall
sensor. Through programming, the MLX90365
provides also a digital PWM (Pulse Width
Modulation) output characteristic.
