Product details
Overview
MLX90373KVS-ABA-303-RX from Melexis is a Triaxis® Hall-effect position processor IC for absolute rotary and linear position sensing using 2-wire PSI5 v1.3/v2.1 output. It operates from -40°C to +125°C, delivers ±0.85° total angular drift (XY mode), supports stray-field immunity up to 5 mT, and is AEC-Q100 Grade 0 qualified for automotive pedal and throttle position systems.
For engineers reviewing the MLX90373KVS-ABA-303-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package with 4-pin 2-wire PSI5 interface, programmable piecewise-linear transfer characteristic (up to 32 points), ISO 26262 SEooC ASIL-C compliance, and legacy-mode magnetic sensitivity of 11–20 mT BNorm.
Technical Context
The MLX90373KVS-ABA-303-RX implements Triaxis® technology to measure all three orthogonal magnetic field components (BX, BY, BZ), enabling robust absolute angle or linear displacement decoding via on-chip DSP. Its -30x option code configures it for Legacy/Standard mode-supporting both angular and linear applications with 2-pole magnet compatibility and x-y/x-z/y-z sensing modes.
This variant uses the DMP-4 (dual-mold PCB-less) package with VSS/VDD/N.C./VSS pinout and operates over 4.1–6 V supply during PSI5 communication. It features 24 MHz main clock (±5% tolerance), 850 µs default latency, and 1480–2125 µs worst-case step response-optimized for real-time ECU feedback in safety-critical vehicle subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +125°C - supports under-hood automotive environments without derating. |
| Supply Voltage | 4.1–6 V - compatible with standard 5 V automotive power rails and PSI5 bus operation. |
| PSI5 Protocol | v1.3 & v2.1 compliant - enables deterministic 2-wire sensor communication over supply line with 300–500 µs cycle time. |
| Angular Accuracy | ±0.85° total drift (XY mode) - calibrated performance across temperature and lifetime, referenced to 35°C. |
| Magnetic Sensitivity | 11–20 mT BNorm - defines minimum usable field strength for nominal accuracy in Legacy mode. |
| Stray Field Immunity | Not applicable - this -303 variant is configured for Legacy mode, not Stray-Field Immune (-10x) operation. |
| Functional Safety | ISO 26262 SEooC ASIL-C - provides safety mechanisms documented for integration into ASIL-B/C systems. |
| AEC-Q100 | Grade 0 qualified - validated for continuous operation at 125°C junction temperature. |
Pinout & Package
DMP-4 is a dual-mold, PCB-less surface-mount package with 4 terminals and no internal substrate. It supports compact, low-profile mounting directly onto flex or rigid PCBs with face-down tape-and-reel delivery (RX).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital circuitry; must be connected to system ground for EMC stability. |
| 2 | VDD | Supply input and PSI5 data output line; carries bidirectional current-modulated PSI5 frames. |
| 3 | N.C. | No internal connection; electrically isolated and must remain unconnected per design. |
| 4 | VSS | Second ground terminal; improves thermal dissipation 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 cams or gears. |
| Programmable Transfer Curve | Supports 4-, 8-, 17-, or 32-point piecewise-linear calibration - corrects nonlinearity from magnet geometry and air gap variation. |
| Legacy Mode (-30x) | Configured for standard angular/linear applications with 2-pole magnets and x-y/x-z/y-z sensing flexibility - distinct from stray-field immune variants. |
| PSI5 v2.1 Interface | 2-wire current modulation eliminates separate data lines, simplifies harness routing, and meets automotive EMI requirements for sensor networks. |
| On-Chip Diagnostics | Includes analog/digital watchdogs (IWD/AWD), magnetic field monitoring (BTH_LOW/HIGH), and CRC-protected frame validation - supports ASIL-C fault detection. |

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-303-RE | TSSOP-16 dual-die redundant package; higher quiescent current (2×10.5 mA); isolation-rated between dice. | Required for ASIL-D systems needing hardware redundancy; unsuitable for space-constrained DMP-4 footprints. | Select when functional safety requires die-level redundancy and PCB area permits TSSOP-16. |
| MLX90373KDC-ABA-303-RE | SOIC-8 single-die package; 8-pin layout; different pinout (VDD/IN/TEST/N.C./IDATA/N.C./VDEC/VSS); 6–18 V PSI5 operating range. | Better suited for prototyping and legacy board designs with SOIC footprints; lacks DMP-4's ultra-low profile. | Choose for development boards or cost-sensitive industrial applications where SOIC-8 is already standardized. |
Compared with MLX90373KVS-ABA-303-RX, the GO variant adds hardware redundancy at the cost of size and current draw, while the DC variant trades compactness for broader voltage support and easier hand-soldering-neither is pin-compatible, but all share identical core sensing algorithms and PSI5 protocol behavior.

FAQ
What is the primary sensing mode configured for MLX90373KVS-ABA-303-RX?
The MLX90373KVS-ABA-303-RX is factory-configured for Legacy/Standard mode (option code -303), supporting both angular and linear position sensing using 2-pole magnets and x-y/x-z/y-z field component combinations. It does not implement the Rotary Stray-Field Immune algorithm found in -10x variants.
Does MLX90373KVS-ABA-303-RX support programmable calibration, and how is it implemented?
Yes, MLX90373KVS-ABA-303-RX supports end-user programmable transfer characteristics including 4-, 8-, 17-, or 32-point piecewise-linear (PWL) calibration stored in NVRAM. Calibration is performed via PTC (Programming Through Connector) using Melexis' PTM software and requires no external MCU intervention during runtime.
What are the absolute maximum ratings for supply voltage on MLX90373KVS-ABA-303-RX?
The MLX90373KVS-ABA-303-RX has an absolute maximum supply voltage of 27 V for durations under 24 hours at junction temperatures below 175°C. For short transients, it withstands up to 37 V for ≤60 seconds at ambient ≤35°C-exceeding these limits risks permanent damage per datasheet Table 6.
How does the DMP-4 package of MLX90373KVS-ABA-303-RX differ from SOIC-8 and TSSOP-16 variants?
The DMP-4 package of MLX90373KVS-ABA-303-RX is a dual-mold, PCB-less construction with only four terminals (VSS/VDD/N.C./VSS), enabling ultra-low profile mounting and reduced assembly cost. Unlike SOIC-8 (8-pin) or TSSOP-16 (16-pin dual-die), DMP-4 lacks internal substrate and requires face-down tape-and-reel (RX) handling.
Is MLX90373KVS-ABA-303-RX certified for functional safety applications, and what level does it achieve?
Yes, MLX90373KVS-ABA-303-RX is certified as a Safety Element out of Context (SEooC) meeting ISO 26262 requirements at ASIL-C. This includes documented safety mechanisms such as dual watchdogs (IWD/AWD), magnetic field monitoring, CRC-protected PSI5 frames, and diagnostic coverage analysis-enabling integration into ASIL-B or ASIL-C systems.
