Product details
Overview
MLX90367EDC-ABU-000-SP from Melexis is a Triaxis® Hall-effect position sensor IC in SOIC-8 package, delivering 12-bit resolution SENT output per SAE J2716-2010, with programmable linear transfer characteristic and thermal offset correction. It measures absolute rotary or linear position via orthogonal and parallel magnetic flux components (BX, BY, BZ), enabling non-contacting potentiometer replacement in automotive throttle and steering systems.
For engineers reviewing the MLX90367EDC-ABU-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, ±1° intrinsic angle linearity error at 25°C, -40°C to +150°C operation, SOIC-8 RoHS packaging, and end-user programmability of measurement range and transfer curve.
Technical Context
The MLX90367EDC-ABU-000-SP integrates a 16-bit RISC DSP core (2.5 MIPS @ 10 MHz) with on-chip analog signal processing for real-time 3-axis magnetic field decomposition using CoRDiC algorithms. Its Triaxis® architecture enables direct computation of absolute angular position (0–360°) or linear displacement from BX, BY, and BZ inputs without external magnets or complex mechanical coupling.
It implements SENT frame transmission with Throttle Sensor Format or Secure Sensor Format, supporting diagnostic reporting via fast channel and enhanced serial messages via slow channel. The device features factory-trimmed IMC gain (1.2–1.8× for XY, 1.1–1.3× for Z), programmable k-factor (1.0–1.5), and configurable FIR filter (FILTER=0/1/2) to optimize latency-noise trade-off.

Pinout & Package
MLX90367EDC-ABU-000-SP uses an 8-pin SOIC-8 package (RoHS compliant) with exposed pad not electrically connected. Pin 1 is VDD; pins 2, 3, and 6 are test terminals recommended to be tied to ground for EMC stability; pin 5 is SENT output; pins 7 and 8 provide digital supply (VDIG) and ground (VSS).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main analog/digital supply input (4.5–5.5 V); requires local 100 nF decoupling. |
| 2 | Test 0 | Factory test terminal; must be connected to VSS for optimal EMC performance. |
| 3 | Test 2 | Factory test terminal; must be connected to VSS for optimal EMC performance. |
| 4 | Not Used | No internal connection; leave unconnected or tie to VSS. |
| 5 | OUT | SENT output signal (open-drain, 0–5 V logic); drives single-wire bus to ECU. |
| 6 | Test 1 | Factory test terminal; must be connected to VSS for optimal EMC performance. |
| 7 | VDIG | Digital supply rail; internally regulated from VDD; powers SENT driver and logic. |
| 8 | VSS | Analog/digital ground reference; low-impedance return path essential for accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous BX, BY, BZ detection enables absolute position decoding without magnet reorientation or multi-sensor stacking. |
| Programmable Transfer Characteristic | Multi-point linearization (3-pt or 17-pt LNR) allows custom calibration to mechanical nonlinearity in throttle or pedal linkages. |
| SENT Diagnostic Messaging | Fast-channel diagnostics (e.g., open-circuit, short-to-battery) and slow-channel OEM-defined serial messages improve system-level fault coverage. |
| Thermal Output Offset Correction | Compensates for temperature-induced zero-point drift in high-temp environments, maintaining ≤±0.3° angular error across full range. |
| End-User EEPROM Programmability | 128 B EEPROM stores calibration coefficients, ID, lock status, and filter settings - enables post-manufacture tuning without hardware change. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367GO-ACU-000-RE | TSSOP-16 dual-die package with full redundancy; higher pin count, larger footprint, no test pin grounding requirement. | Required for ASIL-B/C safety-critical functions (e.g., steer-by-wire); supports independent diagnostic monitoring per die. | Select when functional safety compliance (ISO 26262) mandates hardware redundancy. |
| MLX90364KGO-ABG-000-RE | Legacy Triaxis® IC with PWM output only; no SENT interface; 10-bit resolution; lacks thermal offset correction and multi-point LNR. | Suitable for cost-sensitive, non-diagnostic applications where ECU lacks SENT receiver (e.g., older engine control units). | Select only if SENT capability is unnecessary and legacy PWM interface suffices. |
Compared with MLX90367EDC-ABU-000-SP, the TSSOP-16 MLX90367GO-ACU-000-RE adds hardware redundancy for safety-critical use, while the MLX90364KGO-ABG-000-RE sacrifices SENT, resolution, and thermal correction for lower BOM cost in legacy systems.

FAQ
What is the operating temperature range of the MLX90367EDC-ABU-000-SP?
The MLX90367EDC-ABU-000-SP operates from -40°C to +150°C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive environments. This range is validated across all electrical parameters including SENT timing, thermal offset correction, and magnetic sensitivity, ensuring reliable performance in throttle bodies and brake modules.
Does the MLX90367EDC-ABU-000-SP support SENT protocol revision compatibility?
Yes, the MLX90367EDC-ABU-000-SP implements SENT per SAE J2716-2010 and supports both Throttle Sensor Format and Secure Sensor Format. Its SERIAL_SENTREV register defaults to 0x3 (2010 revision), and CRC2010 bit enables CRC-2010 checksum generation, ensuring interoperability with modern ECUs.
How is the MLX90367EDC-ABU-000-SP calibrated for different mechanical configurations?
The MLX90367EDC-ABU-000-SP supports end-user programmable 3-point or 17-point linearization (LNR) via its 128 B EEPROM. Engineers configure LNRS0/LNRAX–LNRCS coefficients during final test to map raw magnetic angle to mechanical stroke or rotation, compensating for linkage geometry and magnet placement tolerances.
What is the purpose of the test pins (2, 3, 6) on the MLX90367EDC-ABU-000-SP SOIC-8 package?
Pins 2 (Test 0), 3 (Test 2), and 6 (Test 1) are factory test terminals with no functional role in normal operation. Melexis specifies they must be connected to VSS (ground) on the PCB to minimize electromagnetic emissions and ensure stable SENT signal integrity per ISO 11452-4.
Can the MLX90367EDC-ABU-000-SP be used in safety-critical automotive systems?
The MLX90367EDC-ABU-000-SP itself is not ASIL-certified as a single-die SOIC-8 device. For ASIL-B/C applications like EPS or brake-by-wire, Melexis recommends the dual-die TSSOP-16 variant (e.g., MLX90367GO-ACU-000-RE), which provides hardware redundancy and independent diagnostic paths required by ISO 26262.
