Product details
Overview
MLX90373KVS-ABA-103-RE from Melexis is a Triaxis® Hall-based absolute rotary position sensor IC with stray-field immunity, 2-wire PSI5 v1.3/v2.1 output, AEC-Q100 Grade 0 qualification, and ±0.85° total angular drift over −40°C to +125°C. It operates in DMP-4 package with dual-ground 4-pin configuration and delivers robust angle sensing up to 360° in automotive pedal and throttle applications.
For engineers reviewing the MLX90373KVS-ABA-103-RE datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immune operation (−10x option code), PSI5 timing compliance (Tcycle = 300–500 µs), angular accuracy under thermal drift, magnetic gradient sensitivity (≥4.1 mT/mm), and functional safety support per ISO 26262 SEooC ASIL-C.
Technical Context
The MLX90373KVS-ABA-103-RE implements Triaxis® Hall technology to measure all three magnetic field components (BX, BY, BZ) for absolute angle decoding. Its on-chip DSP performs real-time piecewise-linear (PWL) transfer function correction using up to 32 programmable points, enabling precise linearization of non-ideal magnet trajectories.
This variant uses the −10x option code, configuring it exclusively for Rotary Stray-Field Immune mode: it processes magnetic in-plane gradient (∆BXY/∆XY) as the useful signal, rejecting uniform stray fields up to 5 mT (4 kA/m) per ISO 11452-8, with immunity validated across full 180° mechanical range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | −40°C to +125°C - supports under-hood automotive environments without derating. |
| PSI5 Cycle Time | 300–500 µs - enables high-speed closed-loop control at up to 3.3 kHz frame rate. |
| Total Angular Drift | ±0.85° - maximum peak-to-peak deviation relative to 35°C calibration point over lifetime and temperature. |
| Stray-Field Immunity | Up to 5 mT (4 kA/m) - maintains <0.6° error under ISO 11452-8 compliant interference. |
| Magnetic Gradient Sensitivity | ≥4.1 mT/mm - minimum usable signal for nominal accuracy in stray-field immune mode. |
| Supply Voltage Range | 6–18 V - compatible with 12 V automotive battery systems including load-dump transients. |
| Quiescent Current | 10–13.5 mA - power budget compatible with always-on ECU modules. |
Pinout & Package
DMP-4 package: dual-mold, PCB-less, 4-terminal surface-mount device with straight leads (STD2 2.54 mm pitch per ordering legend). No internal PCB; terminals are directly bonded to die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground return path - must be connected to low-impedance chassis ground for EMC stability. |
| 2 | VDD | Supply input / PSI5 data output - powers IC and carries bidirectional PSI5 current-modulated signal. |
| 3 | N.C. | No internal connection - electrically isolated; recommended to tie to ground for shielding. |
| 4 | VSS | Second ground terminal - provides dedicated return for PSI5 current loop, reducing common-mode noise. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous BX, BY, BZ measurement enables true 3D magnetic field reconstruction for absolute angle decoding without mechanical cam or gear constraints. |
| Stray-Field Immune Mode | Processes ∆BXY/∆XY gradient as primary signal - rejects uniform external fields up to 5 mT while preserving full 0–360° angular resolution. |
| Programmable PWL Transfer | Supports 32-point piecewise-linear calibration - corrects nonlinearities from magnet geometry, air gap variation, and mechanical misalignment in production. |
| AEC-Q100 Grade 0 | Qualified for 125°C ambient operation - meets automotive engine compartment reliability requirements including HTOL, TC, and ESD stress. |
| ISO 26262 SEooC ASIL-C | Delivers safety mechanisms including dual watchdogs (IWD/AWD), ECC-protected NVRAM, and diagnostic coverage for sensor front-end and signal chain. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374KGO-ABA-103-RE | TSSOP-16 dual-die redundant architecture; higher isolation resistance (4 MΩ); 2× quiescent current (21 mA typical). | Required for ASIL-D systems needing hardware redundancy; not drop-in due to 16-pin footprint and different pinout. | Select when functional safety requires full hardware redundancy and board space permits TSSOP-16 layout. |
| MLX90371KDC-ABA-100-RE | SOIC-8 single-die package; lower max supply (6 V); no stray-field immune mode - limited to legacy angular/linear configurations. | Suitable only for non-critical cabin or body applications; lacks ISO 11452-8 validation and ASIL-C certification. | Choose for cost-sensitive, non-safety-critical designs where 125°C operation and stray-field immunity are not required. |
Compared with MLX90373KVS-ABA-103-RE, the MLX90374KGO-ABA-103-RE adds hardware redundancy at the cost of doubled current and larger footprint, while the MLX90371KDC-ABA-100-RE sacrifices stray-field immunity, ASIL-C compliance, and extended voltage range for SOIC-8 simplicity and lower BOM cost.

FAQ
What is the primary magnetic sensing mode configured for MLX90373KVS-ABA-103-RE?
The MLX90373KVS-ABA-103-RE is factory-configured for Rotary Stray-Field Immune mode (−10x option code), which uses magnetic in-plane gradient (∆BXY/∆XY) as the primary signal. This mode enables immunity to uniform external fields up to 5 mT and supports full 0–360° absolute angle measurement with <0.6° error under ISO 11452-8 test conditions. The MLX90373KVS-ABA-103-RE does not support legacy angular or linear modes unless reprogrammed via PTC.
Does MLX90373KVS-ABA-103-RE support PSI5 v2.1 communication?
Yes, MLX90373KVS-ABA-103-RE fully supports PSI5 v2.1 protocol as specified in its datasheet Revision 2.0. It complies with cycle times of 300–500 µs, bit timing of 5–8.4 µs, and synchronous mode sync pulse hold time ≥9 µs. The MLX90373KVS-ABA-103-RE also maintains backward compatibility with PSI5 v1.3, allowing seamless integration into existing ECU platforms without firmware updates.
What is the maximum allowable stray magnetic field for MLX90373KVS-ABA-103-RE without degrading accuracy?
The MLX90373KVS-ABA-103-RE maintains ≤0.6° angular error under stray magnetic fields up to 5 mT (4 kA/m) applied from any direction, as validated per ISO 11452-8:2015. This performance is guaranteed only in Rotary Stray-Field Immune mode (−10x), where the device processes magnetic gradient rather than absolute flux density. The MLX90373KVS-ABA-103-RE's immunity scales linearly with both useful field strength and disturbing field magnitude.
Can MLX90373KVS-ABA-103-RE be used in linear position sensing applications?
No - MLX90373KVS-ABA-103-RE is specifically configured for Rotary Stray-Field Immune operation (option code −103) and does not support linear position sensing modes. Linear applications require −30x option codes (e.g., ABA-300/303/308) that enable legacy x-y, x-z, or y-z sensing configurations. Using MLX90373KVS-ABA-103-RE for linear displacement would result in undefined behavior and uncalibrated output due to mismatched magnetic transfer function.
What packaging and lead configuration does MLX90373KVS-ABA-103-RE use?
MLX90373KVS-ABA-103-RE uses the DMP-4 (Dual Mould Package) - a PCB-less, 4-terminal surface-mount device with STD2 trim-and-form leads spaced at 2.54 mm pitch. Its pinout is VSS–VDD–N.C.–VSS, with two dedicated ground terminals for enhanced PSI5 current-loop integrity and EMC robustness. The MLX90373KVS-ABA-103-RE is delivered in tape-and-reel (RE) format with face-up orientation.
