Product details
Overview
MLX90367LDC-ABU-000-SP from Melexis is a Triaxis® monolithic Hall-effect position sensor IC in SOIC-8 package, delivering 12-bit absolute angular or linear position data via SENT output (SAE J2716-2010), with 10-bit thermal accuracy, programmable transfer characteristic, and on-chip signal processing for robust non-contact sensing in automotive throttle and steering applications.
For engineers reviewing the MLX90367LDC-ABU-000-SP datasheet, pinout, applications, or equivalent options, key selection considerations include SENT protocol compliance, ±150 °C operating range, 12-bit resolution with thermal offset correction, and SOIC-8 footprint compatibility for pedal and float-level sensor designs.
Technical Context
The MLX90367LDC-ABU-000-SP integrates three orthogonal Hall elements (BX, BY, BZ) with on-die DSP performing CoRDiC-based rectangular-to-polar conversion to compute absolute angle or displacement. Its SENT output supports Throttle Sensor Format with fast-channel diagnostics and slow-channel enhanced serial messages.
It features factory-trimmed IMC gain (1.2–1.8× for XY, 1.1–1.3× for Z), programmable 3-point linearization (LNR), and thermal offset correction-enabling <±0.3° angular error at 25 °C and <±0.15° drift over temperature when calibrated per application requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | SENT (SAE J2716-2010), Throttle Sensor Format - enables direct connection to automotive ECUs without external ADC or protocol translation. |
| Resolution & Accuracy | 12-bit position resolution, 10-bit thermal accuracy - delivers ≤0.3° angular error at 25 °C with factory trim and IMC calibration. |
| Operating Temperature | −40 °C to +150 °C - qualified for under-hood automotive applications including throttle and steering wheel position sensing. |
| Magnetic Sensitivity | BX/BY ≥70 mT, BZ ≥126 mT - supports compact magnet designs with high signal-to-noise ratio and low linearity degradation. |
| Supply Voltage | 4.5–5.5 V - compatible with standard 5 V automotive power rails and tolerant of transient overvoltage up to +24 V. |
| Package | SOIC-8, RoHS-compliant - surface-mount footprint with proven reliability in vibration-prone environments. |
| Latency | 1745 μs average field-to-SENT latency (FILTER = 1) - meets real-time control loop timing for closed-loop actuation systems. |
Pinout & Package
SOIC-8 package with 1.27 mm pitch, 5.0 mm × 6.2 mm body, and exposed pad option (not applicable to ABU variant). Pin 1 = VDD, Pin 5 = SENT output, Pin 8 = VSS (ground); unused test pins (2, 3, 4, 6, 7) must be tied to ground per EMC guidelines.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main supply input (4.5–5.5 V); internal LDO powers analog and digital blocks. |
| 2 | Test 0 | Factory test pin - not connected in final application; must be grounded for EMC compliance. |
| 3 | Test 2 | Factory test pin - not connected in final application; must be grounded for EMC compliance. |
| 4 | Not Used | No internal connection; tie to ground to minimize noise coupling. |
| 5 | OUT | SENT output (open-drain, 18 V tolerant); delivers encoded position, diagnostics, and OEM data frames. |
| 6 | Test 1 | Factory test pin - not connected in final application; must be grounded for EMC compliance. |
| 7 | VDIG | Digital supply rail - internally connected to VDD; decoupling recommended near pin. |
| 8 | VSS | Analog/digital ground reference - single-point grounding critical for noise immunity in SENT signaling. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall architecture | Senses BX, BY, BZ simultaneously - enables absolute rotary (0–360°) or linear position from a single moving magnet without mechanical stops or gears. |
| Programmable 3-point linearization | User-configurable LNR parameters (LNRS0, LNRAX–LNRCS) - corrects magnetic nonlinearity in custom mechanical assemblies without host MCU intervention. |
| SENT Throttle Sensor Format | Fast-channel diagnostic reporting (e.g., open-circuit, short-to-battery) plus slow-channel OEM-defined serial messages - satisfies ASAM MCD-2 MC and ISO 26262 diagnostic coverage requirements. |
| Thermal offset correction | Compensates for temperature-induced zero-point drift - maintains <±0.3° angular accuracy across −40 °C to +150 °C without external compensation circuitry. |
| 48-bit unique ID | Factory-programmed EEPROM identifier - enables full traceability, secure firmware binding, and counterfeit detection in Tier-1 production lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367LGO-ACX-000-RE | TSSOP-16 dual-die package with full redundancy and thermal offset correction; higher pin count, larger footprint. | Required for ASIL-D redundant architectures; supports independent die diagnostics and cross-checking. | Select when functional safety mandates hardware redundancy per ISO 26262 Part 10 Annex D. |
| MLX90364KDC-ABG-000-SP | Legacy Triaxis® device with PWM output only; no SENT support; 10-bit resolution; same SOIC-8 package. | Limited to legacy ECU interfaces without SENT receivers; lacks multi-point linearization and enhanced diagnostics. | Choose only for cost-sensitive, non-safety-critical replacements where SENT is unavailable and 12-bit resolution is unnecessary. |
Compared with MLX90367LDC-ABU-000-SP, the ACX TSSOP-16 variant adds hardware redundancy for ASIL-D compliance but requires PCB redesign, while the MLX90364 offers lower-cost PWM-only operation at reduced resolution and diagnostic capability-neither is pin-compatible nor drop-in replaceable.

FAQ
What is the operating temperature range of the MLX90367LDC-ABU-000-SP?
The MLX90367LDC-ABU-000-SP operates from −40 °C to +150 °C, meeting AEC-Q100 Grade 0 requirements for under-hood automotive use. This range is validated across all electrical parameters including SENT timing, thermal offset drift, and magnetic sensitivity, ensuring consistent performance in engine control, throttle, and steering applications where ambient heat exceeds 125 °C.
Does the MLX90367LDC-ABU-000-SP support SENT protocol version compatibility?
Yes, the MLX90367LDC-ABU-000-SP implements SENT per SAE J2716-2010, supporting both Throttle Sensor Format (fast-channel diagnostics + position) and Secure Sensor Format (enhanced serial messages). It uses SENT revision code 0x3 (J2716-2010), and frame timing (882 μs period) is fixed per specification - no software configuration is required for basic interoperability with compliant ECUs.
Can the MLX90367LDC-ABU-000-SP be programmed for custom linearization curves?
Yes, the MLX90367LDC-ABU-000-SP supports end-user programmable 3-point linearization (LNR) via EEPROM registers LNRS0, LNRAX–LNRCS. These parameters define piecewise-linear transfer characteristics to compensate for mechanical/magnetic nonlinearities in custom assemblies - programming is performed using Melexis' PTM or customer-specific tools before final system integration.
What is the significance of the "ABU-000" option code in MLX90367LDC-ABU-000-SP?
The "ABU-000" option code identifies a specific die revision and configuration: ABU denotes a non-recommended-for-new-design variant with 3-point LNR capability (AxU version), standard EEPROM settings, and SOIC-8 packaging. While fully functional and qualified, Melexis advises new designs use ACU-xxx variants for extended support and updated calibration defaults - ABU remains available for legacy program continuity.
How does the MLX90367LDC-ABU-000-SP handle electromagnetic interference in automotive environments?
The MLX90367LDC-ABU-000-SP incorporates integrated EMC countermeasures including differential Hall sensing, on-die filtering (configurable FIR), SENT's inherent noise immunity, and mandatory grounding of unused test pins. Its SOIC-8 layout and internal IMC structure provide >100 dB common-mode rejection, validated per ISO 11452-2/4/8 and CISPR 25 Class 5, making it suitable for placement near ignition coils or DC motors without external shielding.
