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) 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 surfacemount packages (SOIC-8 – single die & TSSOP-16 – dual die). The decoupling capacitors are 4 identical 100nF/X8R well suited for package integration and the target operating temperature range. 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. BX, BY and BZ). 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. MLX90364 Triaxis® Position Sensor Assembly enables the realization of position sensor modules for which a PCB is no longer needed: this yield to an increase of the electrical, mechanical and environmental robustness of the final application.

Description As described on the block diagram the three vector components of the magnetic flux density (BX, BY and BZ) applied to the IC are sensed through the sensor front-end. The respective Hall signals (VX, VY and VZ) are generated at the Hall plates and amplified. The analog signal processing is based on a fully differential analog chain featuring the classic offset cancellation technique (Hall plate 2-Phases spinning and chopper-stabilized amplifier). The conditioned analog signals are converted through an ADC (15 bits) and provided to a DSP block for further processing. The DSP stage is based on a 16 bit RISC micro-controller whose primary function is the extraction of the position from two (out of three) raw signals (after so-called front-end compensation steps) through the following function: α = ∠(V1 , k ⋅V2 ) where alfa is the magnetic angle 170degC (± 20) Saturate value used for the compensations to -40degC and Temperature < -60degC (± 20) +150degC resp.

Built-in Capacitors and recommended Application Diagrams Figure 12 – Recommended wiring for the MLX90364 in DMP-4 Either Vss pin can be used for grounding, but always leave 1 floating. Built-in capacitors are ceramic multilayer type X8R with value of 100nF each. The capacitors are specifically suited for high temperature applications with stable capacitance value (+/15%) up to 150 DegC. The capacitors are assembled using a gluing method instead of soldering to be more reliable towards thermal/mechanical stress. The maximum rated voltage is 25V.
