Product details
Overview
MLX90367EGO-ACU-000-SP from Melexis is a Triaxis® Hall-effect position sensor IC delivering absolute rotary or linear position measurement via SENT output (SAE J2716-2010). It resolves 3-axis magnetic flux (BX, BY, BZ) with 12-bit resolution and 10-bit thermal accuracy in a TSSOP-16 dual-die package, enabling robust non-contact sensing in automotive throttle and steering wheel position systems.
For engineers reviewing the MLX90367EGO-ACU-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include SENT protocol compliance, dual-die redundancy, programmable 3-point linear transfer characteristic, thermal offset correction capability, and operation across –40 °C to +150 °C.
Technical Context
The MLX90367EGO-ACU-000-SP integrates on-chip analog signal processing (ASP) and digital signal processing (DSP) to compute absolute angular or linear position from orthogonal and parallel magnetic field components. Its dual-die architecture provides full hardware redundancy for functional safety-critical applications.
It implements SENT output using Throttle Sensor format with fast-channel diagnostics and slow-channel enhanced serial messages. The DSP core is a 16-bit RISC microcontroller running at 10 MHz (2.5 MIPS), supporting end-user programming of transfer characteristics, clamping limits, and diagnostic settings via EEPROM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367KGO-ACU-000-RE | Same die, TSSOP-16 package, but rated for –40 °C to +125 °C (K grade) instead of L grade (–40 °C to +150 °C) | Suitable for under-hood applications with lower max ambient temperature; not qualified for engine valve train or turbocharger zones | Select when thermal budget allows margin below 150 °C and cost optimization is prioritized |
| MLX90367EGO-ACV-000-RE | Same package and temperature range, but supports 17-point LNR calibration (vs. 3-point in ACU) and no thermal offset correction | Better linearity correction for high-precision industrial encoders; lacks thermal drift compensation needed in automotive powertrain | Choose for applications demanding ultra-low INL where thermal stability is managed externally |
Compared with MLX90367EGO-ACU-000-SP, the K-grade alternative trades thermal range for cost, while the ACV variant offers higher linearization granularity at the expense of thermal drift mitigation-making MLX90367EGO-ACU-000-SP optimal for safety-critical automotive positions where both extended temperature operation and thermal stability are mandatory.

FAQ
What is the operating temperature range of the MLX90367EGO-ACU-000-SP?
The MLX90367EGO-ACU-000-SP operates from –40 °C to +150 °C, certified to the L temperature grade per Melexis ordering nomenclature. This range is validated across all electrical, magnetic, and timing specifications in the official datasheet revision 7.0, making it suitable for engine bay and transmission-mounted position sensing where extreme thermal cycling occurs. The MLX90367EGO-ACU-000-SP maintains 10-bit thermal accuracy within this full span.
Does the MLX90367EGO-ACU-000-SP support SENT protocol compliance with SAE J2716-2010?
Yes, the MLX90367EGO-ACU-000-SP implements SENT output fully compliant with SAE J2716-2010, using the Throttle Sensor format with fast-channel diagnostics and slow-channel enhanced serial messages. Frame period is fixed at 882 μs, and it supports error code reporting, OEM-defined values, and configurable pause pulses. The MLX90367EGO-ACU-000-SP delivers SENT frames from both OUT1 and OUT2 outputs in dual-die mode.
What type of magnetic field configuration does the MLX90367EGO-ACU-000-SP require?
The MLX90367EGO-ACU-000-SP requires a rotating or translating magnet positioned to generate orthogonal (BX, BY) and parallel (BZ) flux components relative to the IC surface. It uses an Integrated Magneto-Concentrator (IMC®) to enhance sensitivity; typical configurations include off-axis rotary magnets or linear sliders with IMC-backed magnets. The MLX90367EGO-ACU-000-SP achieves optimal accuracy when magnetic flux norm remains ≥20 mT and BX/BY ≥70 mT.
How is redundancy implemented in the MLX90367EGO-ACU-000-SP?
Redundancy in the MLX90367EGO-ACU-000-SP is achieved via physically separate dual dice in one TSSOP-16 package, each with independent VDD1/VDD2, VSS1/VSS2, and SENT outputs (OUT1 and OUT2). Isolation resistance between dice exceeds 4 MΩ. The MLX90367EGO-ACU-000-SP supports cross-die comparison for fault detection and meets requirements for ASIL-B/C system architectures without external duplication.
Can the MLX90367EGO-ACU-000-SP be programmed for custom transfer characteristics?
Yes, the MLX90367EGO-ACU-000-SP supports end-user programming of a 3-point linear transfer characteristic (LNR) via EEPROM, allowing calibration of gain, offset, and breakpoints to compensate for mechanical and magnetic tolerances. Parameters like LNRAX, LNRAY, and LNRS0 are user-writable; the MLX90367EGO-ACU-000-SP retains settings after power cycle and supports lock/unlock via MEMLOCK bits to prevent accidental overwrite.
