Description

The MLX90371 is a monolithic sensor sensitive to

the three components of the flux density applied

to the IC (i.e. B

, B

and B

). This allows the

MLX90371, with the correct magnetic design, to

decode the absolute position of any magnet

moving in its vicinity (e.g. rotary position from 0

to 360 Degrees or linear displacement).

The MLX90371GVD-EAC outputs a programmable

ratiometric analog output signal. The analog

output is compatible with any resistive

potentiometer or programmable linear Hall sensor

and is configurable through multi-point calibration

to tune the output to the desired motion and

improve accuracy.

Unique to this variant, compared to the other

MLX90371 products, is the dual die configuration

in the Single Mold Package (SMP) for PCB-less

integration. Configured with side-by-side

mounting of the dies, the Single Mold Package

provides independent outputs (1x per die) with

shared power and ground. The Single Mold

Package has been designed to provide improved

mounting and integration to a housing and

connector leadframe while reducing size

compared to previous PCB-less packages.
