Product details
Overview
MLX90373KVS-ABA-338-RX from Melexis is a Triaxis® Hall-based absolute position processor IC in DMP-4 package, delivering stray-field immune angular/linear position sensing via 2-wire PSI5 v1.3/v2.1 interface, with ±0.85° total angle drift over -40°C to +125°C and 12-bit magnetic field gradient resolution (0.100 mT/mm LSB).
For engineers reviewing the MLX90373KVS-ABA-338-RX datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, DMP-4 terminal mapping, AEC-Q100 Grade 0 qualification status, ISO 26262 SEooC ASIL-C compliance, and real-world use cases in throttle, pedal, and ride height sensing.
Technical Context
The MLX90373KVS-ABA-338-RX implements Triaxis® technology to simultaneously measure BX, BY, and BZ components, enabling robust absolute position decoding from rotating or linearly moving magnets. Its on-chip DSP supports programmable multi-point (4/8-point) or piecewise-linear (17/32-point) transfer characteristics.
This variant uses the -338 option code, indicating Linear/Angular Position mode with Trim-and-Form STD4 2.54 lead configuration in DMP-4 package. It operates with 4.1–6 V supply during PSI5 communication and delivers 1480–2125 µs worst-case step response time under default filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (PSI5) | 4.1–6 V - Enables direct compatibility with automotive 5 V supply rails without external regulation. |
| Quiescent Current | 9–12.5 mA - Optimized for low-power operation in battery-sensitive applications like pedal sensors. |
| Angle Accuracy Drift | ±0.85° - Maximum total angle drift over full temperature range (-40°C to +125°C), referenced to 35°C calibration point. |
| PSI5 Cycle Time | 300–500 µs - Supports high-speed sensor data streaming at up to ~3.3 kHz frame rate. |
| Magnetic Resolution | 0.100 mT/mm LSB - 12-bit resolution of magnetic field gradient norm, critical for sub-degree linearity in linear/rotary modes. |
| Stray Field Immunity | Up to 5 mT (4 kA/m) - Validated per ISO 11452-8; enables reliable operation in ECU-adjacent high-EMI zones. |
| Functional Safety | ISO 26262 SEooC ASIL-C - Provides certified safety mechanisms for integration into ASIL-B/C system architectures. |
Pinout & Package
DMP-4 is a dual-mold, PCB-less package with 4 terminals and straight leads (STD4 2.54 mm pitch). It eliminates PCB assembly cost and reduces footprint while maintaining mechanical robustness for harsh-environment mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be connected to system ground for EMC stability. |
| 2 | VDD | Supply input and PSI5 data output line - enables 2-wire bidirectional communication over power rail. |
| 3 | N.C. | Not connected - internally unassigned; must remain floating or tied to ground per EMC best practice. |
| 4 | VSS | Second ground terminal - improves current return path symmetry and reduces ground loop impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous BX/BY/BZ measurement enables true 3D magnetic field decoding for absolute position without mechanical stops. |
| Programmable Transfer Curve | Supports 4/8-point linear interpolation or 17/32-point piecewise-linear mapping - allows precise compensation of non-ideal magnet geometry and air-gap variation. |
| AEC-Q100 Grade 0 | Qualified for operation from -40°C to +125°C ambient - meets automotive engine bay and transmission control unit thermal requirements. |
| PSI5 v1.3/v2.1 Compliance | Ensures interoperability with standard automotive ECUs using Peripheral Sensor Interface 5 - no custom PHY required. |
| 48-bit ID Number | Enables unique device identification and traceability across production batches - supports secure calibration and firmware binding. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
Use Scenario: Real-time detection of accelerator or brake pedal angular displacement in passenger vehicles. IC Role / Device Role / Timing Role: Absolute rotary position processor providing 12-bit angle output via PSI5 at ≤500 µs cycle time. Use Value: Eliminates potentiometer wear-out and contact bounce; achieves ±0.85° accuracy across full temperature range without recalibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90373KGO-ABA-300-RE | TSSOP-16 dual-die redundant architecture; higher quiescent current (2×10.5 mA); isolation resistance ≥4 MΩ between dice. | Required for ASIL-D system decomposition where hardware redundancy is mandated. | Select when functional safety architecture requires physically independent signal paths - not drop-in compatible due to different package and pin count. |
| MLX90373KDC-ABA-300-RE | SOIC-8 single-die package; 8-pin layout; supports same -30x linear/angular mode but lacks DMP-4's PCB-less mounting. | Suitable for legacy PCB designs with SOIC footprints; lower thermal dissipation than DMP-4 in high-ambient environments. | Choose for board-level integration where surface-mount reliability and reflow compatibility outweigh size constraints. |
Compared with MLX90373KVS-ABA-338-RX, the TSSOP-16 alternative provides hardware redundancy for higher ASIL targets but increases board area and cost, while the SOIC-8 version retains identical sensing performance in a conventional package - neither offers pin-to-pin compatibility with the DMP-4 variant.
