Product details
Overview
MLX90367KGO-ACU-000-RE from Melexis is a Triaxis® Hall-effect position sensor IC in TSSOP-16 package, delivering 12-bit resolution SENT output per SAE J2716-2010, with programmable 3-point linear transfer characteristic and thermal offset correction. It decodes absolute rotary or linear position from orthogonal and parallel magnetic field components (BX, BY, BZ) for automotive pedal and steering angle sensing.
For engineers reviewing the MLX90367KGO-ACU-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified pin mapping, real-world accuracy specs (±0.3° angular error at 25°C), SENT frame timing (882 μs period), dual-die isolation (4 MΩ), and validated alternatives for throttle and ride height sensing designs.
Technical Context
The MLX90367KGO-ACU-000-RE implements Triaxis® technology to simultaneously measure BX, BY, and BZ field components using integrated magneto-concentrators (IMC), enabling full 360° absolute angle computation via CoRDiC-based DSP. Its on-chip signal processing includes 16-bit RISC CPU (2.5 MIPS), 10 KB ROM, and 128 B EEPROM for end-user calibration.
This variant uses the ACU option code-supporting 3-point LNR programming, SENT Throttle Sensor format, and thermal offset correction-within the -40°C to 125°C operating range (K temperature grade) and TSSOP-16 dual-die redundant architecture for functional safety compliance.

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-ACV-000-RE | 17-point LNR programming instead of 3-point; identical package, temperature grade, and SENT interface | Better suited for highly non-linear mechanical paths (e.g., complex linkage geometries) requiring finer transfer curve granularity | Select ACV when mechanical stroke demands >3 calibration points for sub-0.1° residual error after end-of-line tuning |
| MLX90367KGO-ACX-000-RE | Adds thermal output offset correction (enabled by default); same 17-point LNR and dual-die TSSOP-16 package | Required for extended temperature operation where thermal drift dominates error budget (e.g., under-hood transmission position) | Choose ACX when operating continuously above 105°C ambient and angular stability <±0.5° over full range is mandatory |
Compared with MLX90367KGO-ACU-000-RE, the ACV variant offers higher linearization flexibility for complex motion profiles, while the ACX adds active thermal drift compensation-both retain identical pinout, SENT timing, and dual-die safety architecture but require reprogramming of EEPROM calibration tables.

FAQ
What is the operating temperature range of the MLX90367KGO-ACU-000-RE?
The MLX90367KGO-ACU-000-RE is rated for operation from -40°C to +125°C (K temperature grade). This range is validated across all electrical, magnetic, and timing specifications in the official datasheet Rev 7.0, including SENT frame timing stability, thermal offset drift (±60 LSB15), and magnetic sensitivity mismatch (±0.5% for XY axis). The TSSOP-16 dual-die package supports this extended range through optimized thermal resistance and die isolation.
Does the MLX90367KGO-ACU-000-RE support SENT protocol with diagnostic capabilities?
Yes, the MLX90367KGO-ACU-000-RE implements full SAE J2716-2010 SENT compliance, including Throttle Sensor format with dedicated fast channel for real-time diagnostics (e.g., open-circuit, short-to-battery, broken VSS/VDD reporting) and an enhanced slow channel for user-defined serial messages. Diagnostic levels are specified in the datasheet: BVSSPD = 95–97.5% VDD for broken VSS detection, and Dsat_lo = 0.5–2% VDD for active low saturation.
How many programmable points does the transfer characteristic support in the MLX90367KGO-ACU-000-RE?
The MLX90367KGO-ACU-000-RE supports exactly 3 programmable points (LNR) for linearization-AX, AY, and AS coordinates-as defined in the ACU option code. This is confirmed in Table 1 (Ordering Information) and Section 15.1.3 of the datasheet. Unlike ACV or ACX variants, it does not support 17-point LNR programming or thermal offset correction beyond the base ACU feature set.
What is the SENT frame period and latency for the MLX90367KGO-ACU-000-RE?
The MLX90367KGO-ACU-000-RE has a fixed SENT frame period of 882 μs and internal angle measurement period of 441 μs. Latency from field change to SENT data output is 1745 μs when FILTER = 1 (recommended setting), as specified in Table 8 on page 8 of the datasheet. First sync pulse appears within 1.8 ms of power-on, and first valid data is delivered within 6.3 ms (Tsu2).
Is the MLX90367KGO-ACU-000-RE pin-compatible with other MLX90367 variants in TSSOP-16?
Yes, all MLX90367 variants in TSSOP-16 package-including MLX90367KGO-ACU-000-RE, MLX90367KGO-ACV-000-RE, and MLX90367KGO-ACX-000-RE-share identical pinout, footprint, and electrical interface. Differences are confined to EEPROM-programmable features (LNR point count, thermal correction enablement) and do not affect PCB layout, power sequencing, or SENT signal routing.
