Product details
Overview
MLX90367EGO-ACU-000-RE 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, housed in a RoHS-compliant TSSOP-16 dual-die package for functional redundancy. It is used in automotive pedal, steering wheel, and throttle position sensing where robust non-contact operation and diagnostic-rich serial output are required.
For engineers reviewing the MLX90367EGO-ACU-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT frame timing (882 µs period), thermal offset correction capability, programmable 3-point linear transfer characteristic, dual-die isolation resistance (4 MΩ), and operating temperature range up to +150°C.
Technical Context
The MLX90367EGO-ACU-000-RE implements Triaxis® technology using integrated magneto-concentrators (IMC) to sense orthogonal (BZ) and in-plane (BX, BY) magnetic field components. Its on-chip RISC DSP performs real-time rectangular-to-polar conversion (CoRDiC) and applies user-programmable gain, clamping, and discontinuity point settings to generate calibrated angular or linear position data.
It outputs SENT frames in Throttle Sensor format with fast-channel diagnostics and optional slow-channel enhanced serial messages. The dual-die TSSOP-16 configuration provides full hardware redundancy, with isolated power domains (VDIG1/VDD1 and VDIG2/VDD2) and independent SENT outputs (OUT1/OUT2), meeting ASIL-B requirements for safety-critical automotive subsystems.

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, same package, but rated for -40°C to +125°C (vs. +150°C for MLX90367EGO-ACU-000-RE); lower thermal offset drift spec (±60 LSB15 vs. ±90 LSB15 at +150°C). | Suitable for under-hood applications with moderate thermal exposure (e.g., HVAC actuators), not for high-temp exhaust proximity or turbocharger mounts. | Select when ambient temperature stays below +125°C and cost optimization is prioritized over extended thermal margin. |
| MLX90371GO-ABU-000-RE | Next-generation Triaxis® sensor with 16-bit resolution, improved INL (<±0.2°), and extended SENT frame flexibility (multi-sensor daisy-chain support); not pin-compatible. | Targets next-gen ADAS and zonal ECU architectures requiring higher resolution and multi-node SENT networks. | Choose for new designs needing >12-bit precision or SENT daisy-chaining; requires PCB redesign and firmware update due to different pinout and register map. |
Compared with MLX90367KGO-ACU-000-RE, the MLX90367EGO-ACU-000-RE offers extended high-temperature operation (+150°C) critical for exhaust-mounted throttle bodies, while MLX90371GO-ABU-000-RE provides higher resolution and advanced SENT features but mandates layout and firmware changes.

FAQ
What is the operating temperature range of the MLX90367EGO-ACU-000-RE?
The MLX90367EGO-ACU-000-RE operates from -40°C to +150°C, validated per its 'L' temperature suffix. This extended range supports placement in high-heat zones such as near engines, transmissions, or exhaust manifolds, where conventional sensors may fail. All electrical and magnetic specifications-including thermal offset drift (±90 LSB15) and sensitivity mismatch-are guaranteed across this full range.
Does the MLX90367EGO-ACU-000-RE support SENT protocol version compatibility?
Yes, the MLX90367EGO-ACU-000-RE complies fully with SAE J2716-2010 (Revision 3) for SENT output. It supports both Throttle Sensor format (fast-channel diagnostics only) and Secure Sensor format (enhanced serial message with OEM-defined fields), selectable via EEPROM configuration. Frame timing (882 µs period) and tick count (294 ticks) are fixed per specification.
How does the dual-die architecture of the MLX90367EGO-ACU-000-RE improve functional safety?
The MLX90367EGO-ACU-000-RE integrates two fully independent sensor dies in one TSSOP-16 package, each with separate VDD/VDIG/VSS supplies and SENT outputs (OUT1/OUT2). This enables cross-die comparison, fault detection, and ASIL-B compliance without external redundancy circuitry. Isolation resistance between dice exceeds 4 MΩ, preventing common-cause failure propagation.
Can the MLX90367EGO-ACU-000-RE be programmed for custom linearization curves?
Yes, the MLX90367EGO-ACU-000-RE supports end-user programming of a 3-point linear transfer characteristic (LNR) via its EEPROM. Parameters LNRS0, LNRAX–LNRCS define coordinate pairs for piecewise-linear interpolation, enabling compensation of mechanical tolerances, magnet asymmetry, or air-gap variation during final calibration-no host MCU computation required.
What magnetic field strength is required for reliable operation of the MLX90367EGO-ACU-000-RE?
The MLX90367EGO-ACU-000-RE requires a minimum magnetic flux norm of 20 mT (calculated as √[BX² + BY² + (BZ/1.2)²]) for optimal performance. For XY-axis sensing, ≥70 mT is recommended to avoid IMC saturation; for Z-axis, ≥126 mT ensures full dynamic range. Field strength directly impacts noise floor and linearity-designs should validate with actual magnet geometry and air gap.
