Product details
Overview
MLX90367LDC-ABU-000-RE from Melexis is a Triaxis® monolithic Hall-effect position sensor IC delivering absolute rotary or linear position measurement via 3-axis magnetic field sensing (BX, BY, BZ) with SENT output per SAE J2716-2010, 12-bit resolution, and thermal offset correction. It operates from −40 °C to +150 °C in SOIC-8 package and is used in automotive throttle, pedal, and steering wheel position sensing.
For engineers reviewing the MLX90367LDC-ABU-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, programmable multi-point transfer characteristic, thermal accuracy (10-bit), magnetic field range (±1 T), and dual-die redundancy option for functional safety-critical systems.
Technical Context
The MLX90367LDC-ABU-000-RE integrates on-chip analog signal processing (ASP) and digital signal processing (DSP) based on a 16-bit RISC microcontroller (2.5 MIPS @ 10 MHz) to compute absolute angle from orthogonal and parallel magnetic field components. Its Triaxis® architecture uses an integrated magneto-concentrator (IMC) to enhance sensitivity and enable robust non-contact position decoding.
It supports SENT frame transmission in Throttle Sensor or Secure Sensor format, with configurable filter settings (FILTER = 0/1/2), programmable clamping limits, discontinuity point definition, and user-defined serial messages. The device includes diagnostics such as broken VDD/VSS detection, watchdog timer (114.5–121.5 ms), and EEPROM-based configuration storage (128 B).
Key Specifications

Pinout & Package
MLX90367LDC-ABU-000-RE is housed in an 8-pin SOIC-8 package (RoHS compliant), with pins 1–8 arranged in standard dual-in-line configuration. Unused test pins must be connected to ground for optimal EMC performance per datasheet recommendation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Main power supply input (4.5–5.5 V); internal POR threshold at 2.25 V with 50–200 mV hysteresis. |
| 2 | Test 0 | Factory test pin; must be tied to VSS for production use to ensure EMC stability. |

Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Magnetic Sensing | Simultaneous BX, BY, BZ measurement enables absolute position decoding from magnet rotation or translation - eliminates need for external concentrators or multi-sensor assemblies. |

FAQ
What is the operating temperature range of the MLX90367LDC-ABU-000-RE?
The MLX90367LDC-ABU-000-RE is rated for operation from −40 °C to +150 °C (Temperature Code L), making it suitable for under-hood automotive applications including throttle bodies and transmission control modules. This range is validated per AEC-Q100 stress testing and includes full functionality of SENT output, diagnostics, and thermal offset correction across the entire span.
Does the MLX90367LDC-ABU-000-RE support SENT protocol version compatibility?
Yes, the MLX90367LDC-ABU-000-RE implements SENT per SAE J2716-2010, supporting both Throttle Sensor and Secure Sensor frame formats. It delivers fast-channel position data with diagnostic flags and optional slow-channel OEM-defined values. Frame timing (882 μs period) and nibble encoding comply strictly with the 2010 revision, with no backward compatibility to earlier SENT versions.
Can the MLX90367LDC-ABU-000-RE be programmed for custom transfer characteristics?
Yes, the MLX90367LDC-ABU-000-RE supports end-user programmable multi-point linearization: 3-point LNR for basic calibration (AxU variants) or 17-point LNR for high-fidelity correction (AxV/AxX variants). Parameters including CLAMPLOW, CLAMPHIGH, DP (discontinuity point), and CW (clockwise direction) are stored in EEPROM and configured via Melexis' PTraj software or compatible programmers.
What is the magnetic field range supported by the MLX90367LDC-ABU-000-RE?
The MLX90367LDC-ABU-000-RE supports magnetic flux densities up to ±1 T overall, with optimal sensing ranges of ≥70 mT for BX/BY and ≥126 mT for BZ. For best accuracy, the magnetic norm √[BX² + BY² + (BZ/1.2)²] should remain ≥20 mT to maintain signal-to-noise ratio; operation below this threshold increases quantization noise and degrades angular resolution.
Is the MLX90367LDC-ABU-000-RE pin-compatible with other MLX90367 variants?
No - the MLX90367LDC-ABU-000-RE uses the SOIC-8 package (DC code), while dual-die variants like MLX90367LGO-ACX-000-RE use TSSOP-16 (GO code) with different pin count, layout, and internal die configuration. Pin mapping, supply domains (VDIG1/VDIG2), and output structure (OUT vs. OUT1/OUT2) are not interchangeable; PCB redesign is required for migration between package types.
