Product details
Overview
MLX90367LDC-ACX-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), with 12-bit resolution, 10-bit thermal accuracy, and integrated thermal output offset correction. It operates over −40 °C to +150 °C in SOIC-8 package and targets automotive pedal, throttle, and steering angle sensing.
For engineers reviewing the MLX90367LDC-ACX-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, programmable 17-point linearization, thermal offset correction capability, magnetic field sensitivity (±126 mT BZ), and dual-die redundancy readiness.
Technical Context
The MLX90367LDC-ACX-000-SP integrates three orthogonal Hall elements (BX, BY, BZ) with on-chip DSP for real-time rectangular-to-polar conversion using CoRDiC algorithm, enabling robust absolute angular or linear position decoding. Its internal 16-bit RISC CPU runs at 10 MHz (2.5 MIPS) and supports user-programmable transfer characteristics.
It implements SENT output in Throttle Sensor or Secure Sensor format with fast/slow channels, diagnostic reporting, and error codes. The ACX variant includes full 17-point LNR parameter programming and thermal output offset correction-features absent in ACU/ACV variants-making it suitable for high-accuracy, temperature-stable applications requiring <±0.3° angular error.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90367LDC-ACV-000-SP | Lacks thermal output offset correction; retains 17-point LNR programming | Suitable for lower-temperature environments (<125°C) where thermal zero drift is less critical | Select ACV when cost optimization is prioritized and thermal stability requirements are relaxed |
| MLX90367LDC-ACU-000-SP | Supports only 3-point LNR; no thermal offset correction; fixed transfer curve granularity | Targeted at cost-sensitive, low-accuracy applications such as basic ride height or non-safety-critical linear feedback | Choose ACU only for legacy designs or where <±1° angular tolerance is acceptable |
Compared with MLX90367LDC-ACX-000-SP, the ACV variant trades thermal offset correction for reduced cost while retaining high-resolution linearization, whereas the ACU variant sacrifices both features for minimal BOM cost-making ACX the sole choice for ASIL-B–aligned, high-accuracy automotive position sensing.

FAQ
What is the SENT frame period and latency behavior of the MLX90367LDC-ACX-000-SP?
The MLX90367LDC-ACX-000-SP outputs SENT frames every 882 μs (tframe). Field change to SENT data latency is 1745 μs when FILTER = 1 (recommended setting). First angle measurement to sync pulse latency is 1084 μs (ta1); second is 643 μs (ta2). These values are fixed per internal clock (13.3 MHz typical) and unaffected by external load within specified limits.
Does the MLX90367LDC-ACX-000-SP support dual-die redundancy?
No-the MLX90367LDC-ACX-000-SP uses the SOIC-8 package (Package Code "DC"), which contains a single die. Dual-die (full redundant) versions require TSSOP-16 packaging (Package Code "GO") and carry different option codes (e.g., ABX-000). The ACX-000 option is only available in SOIC-8 configuration.
How does thermal output offset correction function in the MLX90367LDC-ACX-000-SP?
The MLX90367LDC-ACX-000-SP implements on-chip thermal output offset correction specifically for the ACX variant, reducing zero-point drift over temperature. At 150°C, this feature limits angular error to ±0.3°-a 50% improvement versus ACU/ACV variants-by dynamically adjusting the output baseline based on internal temperature sensing and factory-trimmed coefficients.
What magnetic field strengths are required for reliable operation of the MLX90367LDC-ACX-000-SP?
The MLX90367LDC-ACX-000-SP requires minimum magnetic flux densities of ±70 mT for BX/BY and ±126 mT for BZ. Magnetic norm (√[BX² + BY² + (BZ/1.2)²]) must exceed 20 mT for optimal signal-to-noise ratio and linearity. Below 20 mT, performance degrades due to reduced SNR; above 70 mT for BX/BY, IMC saturation increases linearity error.
Can the MLX90367LDC-ACX-000-SP be programmed in-system after soldering?
Yes-the MLX90367LDC-ACX-000-SP supports full in-system programming via SENT interface using Melexis' PTi software and compatible programmers. All end-user programmable items-including 17-point LNR, thermal offset correction enablement, diagnostics, and clamping-can be configured post-mounting without removing the device from the PCB.
