Product details

Overview

MLX90366LVS-AEV-250-RE from Melexis is an AEC-Q100 qualified Triaxis® absolute position sensor IC using Hall-effect technology to measure Bx, By, and Bz magnetic field components. It delivers 12-bit resolution with 10-bit thermal accuracy, SENT output per SAE J2716-2010 (Throttle format), and operates across −40 °C to +150 °C for automotive pedal and steering wheel position sensing.

For engineers reviewing the MLX90366LVS-AEV-250-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, 17-point programmable transfer characteristic, on-board diagnostics, thermal offset correction (enabled in AEV variant), and DMP-4 package integration without PCB.

Technical Context

The MLX90366LVS-AEV-250-RE integrates a 16-bit RISC DSP core running at 10 MHz (2.5 MIPS) and performs real-time rectangular-to-polar coordinate conversion via CoRDiC algorithm. Its Triaxis® architecture enables simultaneous orthogonal and parallel flux density measurement using integrated magneto-concentrators (IMC).

It supports user-programmable 17-point piecewise-linear transfer characteristics (LNR), thermal output offset correction (specific to AxX/AEV variants), and dual diagnostic channels - fast channel for error codes and slow channel for enhanced serial messages including OEM-defined values and 48-bit ID.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Interface	SENT (SAE J2716-2010 Throttle format); enables deterministic timing, CRC-protected frames, and diagnostic reporting over single wire.
Resolution & Accuracy	12-bit output resolution; 10-bit thermal accuracy ensures ≤ ±0.3° angular error over −40 °C to +125 °C (±60 LSB₁₅ thermal offset drift).
Operating Temperature	−40 °C to +150 °C; qualified per AEC-Q100 Grade 0, supporting under-hood and transmission-mounted applications.
Magnetic Sensing Range	B_X/B_Y: ≥70 mT; B_Z: ≥126 mT; norm √[B_X²+B_Y²+(B_Z/1.2)²] ≥20 mT - defines minimum usable field for reliable angle calculation.
Supply Voltage	4.5 V to 5.5 V nominal; includes overvoltage protection up to +24 V and reverse voltage tolerance to −12 V.
Power Consumption	6–10 mA typical (power-saving enabled); surge current up to 20 mA during startup - supports low-power automotive subsystems.
Latency	1745 μs average field-to-SENT data latency (FILTER = 1); first sync pulse within 1.8 ms - meets real-time control loop timing for throttle/steering systems.

Pinout & Package

DMP-4 (Dual Mold Package) with 4-pin leadframe, STD1 1.27 mm pitch, RoHS-compliant, no-PCB module integration capable. Pin 1 and Pin 4 are both VSS (ground); Pin 2 is VDD; Pin 3 is SENT output. Either ground pin may be used, but Pin 1 must remain floating if Pin 4 is connected.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	VSS (Ground)	Secondary ground terminal; must be left floating when Pin 4 is used as primary ground - prevents ground loop in module-level assembly.
Pin 2	VDD	Primary power supply input (4.5–5.5 V); includes internal POR, MT4V detection, and overvoltage protection up to +24 V.
Pin 3	OUT	SENT output (open-drain compatible); drives standard 14.7 kΩ pull-up; supports diagnostic saturation levels at 2–3% and 95–98.5% of VDD.
Pin 4	VSS (Ground)	Primary ground terminal; mandatory connection point for return path - ensures stable reference for analog front-end and SENT driver.

Key Features

Feature	Design Value
Triaxis® 3D Magnetic Sensing	Simultaneous B_X, B_Y, B_Z measurement enables true absolute rotary (0–360°) and linear position decoding without mechanical stops or multi-chip solutions.
17-Point Programmable Transfer Curve	User-configurable piecewise-linear mapping (LNR) allows precise calibration to magnet geometry and mechanical nonlinearity - eliminates external lookup tables or host MCU compensation.
SENT Output with Dual Diagnostic Channels	Fast channel reports real-time errors (e.g., open-circuit, short-to-battery); slow channel transmits OEM-defined serial messages, 48-bit ID, and sensor type - reduces ECU software overhead.
On-Chip Thermal Offset Correction	Enabled in AEV variant; compensates for temperature-induced zero-point drift in magnetic signal path - maintains <±0.3° angular accuracy over full automotive temperature range.
No-PCB Module Integration	DMP-4 package supports direct wire bonding to flex or housing - removes solder joint reliability risk and improves mechanical robustness in high-vibration environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90366LVS-AEU-250-RE	Lacks thermal output offset correction; uses same 17-point LNR but no BZ-axis thermal drift compensation.	Suitable for lower-temperature zones (<125 °C ambient) where thermal drift is less critical, e.g., cabin-mounted pedals.	Select AEU for cost-sensitive designs where full −40 °C to +150 °C thermal accuracy is not required.
MLX90366LVS-AEX-250-RE	Includes thermal offset correction and supports enhanced SENT slow-channel messaging (e.g., extended OEM serial data fields).	Preferred for next-gen ADAS modules requiring traceable sensor IDs and multi-message diagnostics beyond basic throttle format.	Choose AEX when OEM mandates 48-bit ID serialization, enhanced slow-channel payload, or tighter thermal spec compliance.

Compared with MLX90366LVS-AEV-250-RE, the AEU variant trades thermal offset correction for lower unit cost in moderate-temperature applications, while the AEX variant adds extended serial messaging capability and identical thermal performance - making AEV the balanced choice for mainstream automotive throttle and pedal systems requiring verified 150 °C operation and diagnostic depth.

FAQ

What is the SENT protocol configuration supported by MLX90366LVS-AEV-250-RE?

The MLX90366LVS-AEV-250-RE implements SAE J2716-2010 SENT with Throttle position format: 12-bit position data, 4-bit CRC, and fast-channel diagnostic bits. Frame period is fixed at 882 μs, and it supports configurable pause pulses and enhanced slow-channel messages containing OEM-defined values and 48-bit ID. The device does not support PWM or analog output modes.

Does MLX90366LVS-AEV-250-RE require an external microcontroller for calibration?

No, MLX90366LVS-AEV-250-RE does not require an external microcontroller for calibration. Its 17-point piecewise-linear transfer characteristic (LNR) and thermal offset correction parameters are programmed directly into on-chip EEPROM using Melexis' PTM or EVK tools. All signal processing - including CoRDiC angle computation, filtering, and SENT encoding - is performed autonomously by the integrated 16-bit RISC DSP.

What is the meaning of "AEV" in MLX90366LVS-AEV-250-RE?

The "AEV" option code in MLX90366LVS-AEV-250-RE denotes a standard version with 17-point LNR programmability and thermal output offset correction enabled. It distinguishes this variant from ADU (3-point LNR, no thermal correction) and AEX (17-point LNR + extended slow-channel messaging). The "250" suffix specifies STD1 1.27 mm pitch DMP-4 packaging.

Can MLX90366LVS-AEV-250-RE operate without a printed circuit board?

Yes, MLX90366LVS-AEV-250-RE is designed for no-PCB module integration using its DMP-4 package. The die is pre-molded with bond pads accessible for direct wire bonding to flexible circuits or metal housings. This eliminates solder joints and improves mechanical robustness - confirmed in Melexis documentation as "Reliable NoPCB Module Integration" for high-vibration automotive applications.

What diagnostic capabilities does MLX90366LVS-AEV-250-RE provide?

MLX90366LVS-AEV-250-RE provides comprehensive diagnostics including broken VDD/VSS detection, open-circuit and short-to-battery output reporting, watchdog timeout monitoring, and SENT frame CRC validation. Diagnostic status is delivered via dedicated bits in the SENT fast channel, while extended fault logs and OEM identifiers are transmitted in the slow channel - enabling ECU-level failure mode analysis without additional hardware.
