Description

The MLX90364 Triaxis® Position Sensor Assembly

is a high accuracy linear and angular position

sensor which eliminates need for inclusion of a

printed circuit board (PCB) within sensing

modules.

This device is based on a Dual Mold Package

(DMP-4) construction, which integrates a Triaxis

position sensing die together with the decoupling

capacitors necessary to meet the strenuous ESD

and EMC requirements. No PCB is needed.

The Triaxis position sensing die is nothing but the

one used for the MLX90365 in conventional

surface-mount packages (SOIC-8 and TSSOP-16).

Similarly to other Triaxis products, the MLX90364

is sensitive to the flux density applied

orthogonally and parallel to the IC surface i.e. the

3 components of the flux density applied to the IC

(i.e. B

, B

and B

). This allows the MLX90364 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).

MLX90364 reports a programmable ratiometric

analog output signal compatible with any resistive

potentiometer or programmable linear Hall

sensor. Through programming, the MLX90364

provides also a digital PWM (Pulse Width

Modulation) output characteristic.
