Product details

Overview

MLX90364LVS-ADD-251-RX from Melexis is an AEC-Q100 qualified absolute rotary and linear position sensor IC based on Triaxis® Hall technology, housed in a robust DMP-4 dual-mold package with integrated decoupling capacitors. It delivers 12-bit analog or PWM output, supports programmable transfer characteristics, and operates across −40 °C to +150 °C for automotive throttle, EGR valve, and turbo actuator sensing.

For engineers reviewing the MLX90364LVS-ADD-251-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, real-world design meaning of key specs, validated pin functions, automotive-grade diagnostics, and confirmed alternative options for position-sensing system design.

Technical Context

The MLX90364LVS-ADD-251-RX integrates a Triaxis® sensing die that measures all three orthogonal magnetic field components (B_X, B_Y, B_Z) to compute absolute angular or linear position without external PCB. Its on-chip DSP performs coordinate rotation (CoRDiC), multi-point piecewise-linear interpolation, and thermal offset correction-enabling accurate decoding of magnet motion under harsh EMI conditions.

It features dual-output capability: ratiometric analog (0–100% V_DD) and programmable PWM (100–1000 Hz), both with open/short diagnostics, over-voltage protection up to +24 V, and under-voltage detection at 3.8–4.2 V. The DMP-4 package embeds up to four internal decoupling capacitors, eliminating need for external EMC filtering components.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5–5.5 V nominal; supports 24 V overvoltage protection-enables direct connection to automotive battery rails without external regulators.
Output Resolution	12-bit analog or PWM; delivers 0.025% V_DD/LSB precision-sufficient for ±0.1° angular accuracy in throttle position systems.
Magnetic Range	20–70 mT normal range; ±1 T absolute max-compatible with standard NdFeB magnets at air gaps typical in EGR and turbo actuators.
Thermal Accuracy	10-bit thermal accuracy over −40 °C to +150 °C-ensures stable output drift < ±0.3° across full automotive temperature range.
Diagnostics	Open/short, broken-track, field-strength, and PWM diagnostics-provides ASIL-B–ready fault reporting without external monitoring circuitry.
Package	DMP-4 dual-mold package with integrated decoupling capacitors-reduces board space, eliminates external ESD/EMC capacitors, and enables no-PCB module integration.
PWM Frequency	Programmable 100–1000 Hz; ±1% initial tolerance after EOL tuning-supports flexible timing alignment with engine control unit sampling windows.

Pinout & Package

DMP-4 is a 4-pin, surface-mount dual-mold package with straight leads (STD4 2.54 mm pitch), RoHS-compliant, and designed for high-reliability automotive modules without printed circuit boards. Sensitive spot positioned per Melexis POD spec STD4 (section 18.1.4).

Pin/Terminal	Circuit Role	Design Meaning

2	VDD	Primary power input (4.5–5.5 V); includes overvoltage clamp to +24 V and reverse voltage protection to −12 V.
3	OUT	Configurable output: ratiometric analog (0–100% V_DD) or PWM (100–1000 Hz); supports push-pull or open-drain modes.
4	VSS (Ground)	Second ground terminal; improves thermal dissipation and reduces ground bounce in noisy automotive environments.

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90364LVS-AED-251-RX	Standard version (not "ADD"); same DMP-4 package, identical pinout and electrical specs; lacks factory-programmed option code ADD-251.	Identical use in throttle/EGR/turbo; requires end-user programming of transfer characteristic instead of pre-configured behavior.	Select AED-251 if custom calibration is preferred; ADD-251 is pre-programmed for specific magnetic circuit and output profile.
MLX90365KGO-ABF-100-SP	SOIC-8 packaged Triaxis® sensor; same core die but conventional PCB-mount format; no integrated capacitors; requires external ESD/EMC filtering.	Suitable for PCB-based designs where DMP-4's no-PCB integration is unnecessary; lower cost but higher system-level component count.	Choose MLX90365 for prototyping or cost-sensitive non-automotive applications; MLX90364LVS-ADD-251-RX is optimized for module-level integration.

Compared with MLX90364LVS-AED-251-RX, the ADD-251 variant offers factory-programmed transfer characteristics and diagnostics, reducing calibration time in production; versus MLX90365, it trades PCB-mount flexibility for superior EMC robustness and reduced bill-of-materials in sealed modules.
