It delivers absolute rotary or linear position measurement up to 360° or full stroke, with 12-bit resolution and ±0.3° angular accuracy at 25°C, deployed in throttle and steering wheel position sensing.
For engineers reviewing the MLX90367LGO-ACV-000-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its 17-point programmable transfer characteristic, dual-die fault-tolerant design, SENT frame timing (882 μs period), thermal offset correction capability, and operation across −40°C to +150°C.
Technical Context
The MLX90367LGO-ACV-000-RE integrates three orthogonal Hall elements (BX, BY, BZ) and on-chip DSP performing CoRDiC-based angle computation, enabling robust absolute position decoding from rotating or linearly moving magnets. Its dual-die TSSOP-16 implementation provides hardware-level redundancy with isolation resistance ≥4 MΩ between dice.
It supports SENT Throttle Position format with fast-channel diagnostics and slow-channel enhanced serial messages (24- or 40-frame sequences), configurable FIR filtering (FILTER = 0/1/2), and user-programmable parameters including discontinuity point, clock direction, clamping limits, and 17-point LNR tables-specifically enabled in the ACV variant per ordering code.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDIG1 | Digital supply for Die 1 - must be decoupled locally; shared ground reference with VSS1 ensures noise-immune digital domain operation. |
| 2 | VSS1 | Digital ground for Die 1 - separate from analog ground to minimize coupling; recommended connection to system ground plane near IC. |
| 3 | VDD1 | Analog supply for Die 1 - powers Hall front-end and ADC; requires low-noise regulation and local 100 nF ceramic decoupling. |
| 4 | Test 01 | Factory test terminal - not connected in normal operation; datasheet recommends tying to VSS1 for optimal EMC performance. |
| 5 | Test 22 | Factory test terminal - unused in application; tie to VSS1 per EMC guidelines to reduce radiated emissions. |
| 6 | OUT2 | Redundant SENT output from Die 2 - identical protocol and timing to OUT1; enables cross-checking or fail-safe voting in ASIL-B/C systems. |
| 7 | Not Used | No internal connection - must be tied to VSS1 to prevent floating node and ensure predictable ESD behavior. |
| 8 | Test 12 | Factory test terminal - unused; connect to VSS1 to maintain signal integrity and meet automotive EMC requirements. |
| 9 | VDIG2 | Digital supply for Die 2 - independent rail allows die-level power sequencing and fault containment. |
| 10 | VSS2 | Digital ground for Die 2 - isolated from VSS1 to support dual-die independence; joined at single-point system ground. |
| 11 | VDD2 | Analog supply for Die 2 - mirrors VDD1 functionality; enables true hardware redundancy with independent analog signal chains. |
| 12 | Test 02 | Factory test terminal - no functional role; tie to VSS2 to suppress parasitic oscillation and improve immunity. |
| 13 | Test 21 | Factory test terminal - unused in field operation; grounding prevents capacitive coupling into sensitive analog paths. |
| 14 | Not Used1 | No internal connection - must be tied to VSS2; omission risks increased susceptibility to high-frequency interference. |
| 15 | OUT1 | Primary SENT output from Die 1 - delivers calibrated angle data, diagnostics, and OEM-defined values per programmed serial message structure. |
| 16 | Test 11 | Factory test terminal - grounded per design recommendation to stabilize internal bias networks and reduce jitter. |

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-ACU-000-RE | 3-point LNR instead of 17-point; no thermal offset correction; same TSSOP-16 dual-die package and SENT interface. | Suitable for cost-sensitive applications where mechanical linearity is high and thermal drift is mitigated externally. | Select ACU for simpler calibration workflows and lower BOM cost where full 17-point flexibility is unnecessary. |
| MLX90367LGO-ACX-000-RE | Includes thermal output offset correction (enabled in ACX); otherwise matches ACV in 17-point LNR and dual-die architecture. | Required when system-level thermal drift exceeds ±0.3° without software compensation - e.g., under-hood transmission position sensing. | Choose ACX over ACV only if measured thermal offset drift exceeds 90 LSB15 across operating range; ACV suffices for most pedal/throttle use cases. |
Compared with MLX90367LGO-ACU-000-RE, the MLX90367LGO-ACV-000-RE adds precision calibration headroom via 17-point LNR while retaining identical packaging and interface; versus MLX90367LGO-ACX-000-RE, it omits thermal offset correction - reducing EEPROM usage and startup latency by ~0.5 ms.

FAQ
What is the SENT frame structure used by the MLX90367LGO-ACV-000-RE?
The MLX90367LGO-ACV-000-RE implements the SAE J2716-2010 Throttle Position format: each 882 μs frame contains four 4-bit nibbles encoding primary angle data, status flags, and diagnostic information. Fast-channel diagnostics report open-circuit, short-to-ground, and supply faults; slow-channel serial messages (24- or 40-frame sequences) deliver OEM-defined values and enhanced error codes. Frame synchronization uses pause pulses aligned to internal angle measurement periods.
Does the MLX90367LGO-ACV-000-RE support functional safety standards like ISO 26262?
Yes, the MLX90367LGO-ACV-000-RE supports ISO 26262 ASIL B through its TSSOP-16 dual-die architecture, which provides hardware-level redundancy with ≥4 MΩ isolation between dice, independent analog/digital supplies, and cross-die diagnostic capabilities. Its SENT output includes built-in CRC and error reporting, and the device undergoes Melexis' automotive qualification process (AEC-Q100 Grade 0). Full ASIL B compliance requires proper system-level integration per ISO 26262 Part 5.
How does the 17-point LNR programming work in the MLX90367LGO-ACV-000-RE?
The MLX90367LGO-ACV-000-RE stores 17 coordinate pairs (X/Y/S) in EEPROM to define a piecewise-linear transfer function mapping raw magnetic field data to calibrated output angle. Programming is performed via Melexis' PTC interface using standard SENT commands; each point corresponds to a specific magnetic field condition, enabling precise compensation for mechanical tolerances and magnet non-uniformity. This capability is exclusive to ACV and ACX variants - ACU uses only 3-point LNR.
What is the maximum operating temperature range for the MLX90367LGO-ACV-000-RE?
The MLX90367LGO-ACV-000-RE operates across −40°C to +150°C, as indicated by its Temperature Code 'L'. This rating is validated per AEC-Q100 Grade 0 and applies to both electrical performance (e.g., 12-bit resolution, SENT timing) and magnetic sensitivity (BX/BY ≥70 mT, BZ ≥126 mT) across the full range. Thermal offset drift remains within ±90 LSB15 (≈±0.45°) at 150°C, supported by on-chip correction algorithms.
Can the MLX90367LGO-ACV-000-RE be used in linear position sensing applications?
Yes, the MLX90367LGO-ACV-000-RE is explicitly designed for both absolute rotary and linear position sensing. In linear mode, it measures BZ component variation along a magnet's stroke axis, converting field gradients into calibrated displacement output. Applications include float-level sensors, ride height sensors, and brake pedal position - all leveraging the same 17-point LNR, SENT interface, and −40°C to +150°C operation as rotary use cases.
