Product details
Overview
MLX90373KVS-ABA-300-RX from Melexis is a Triaxis® Hall-effect position processor IC for absolute linear and angular position sensing using 2-wire PSI5 v1.3/v2.1 output. It operates from -40°C to +125°C, delivers ±0.85° total angle drift (rotary mode), supports stray-field immunity up to 5 mT, and is AEC-Q100 Grade 0 qualified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90373KVS-ABA-300-RX datasheet, pinout, applications, or equivalent options, key selection criteria include PSI5 interface compliance, DMP-4 package mechanical form factor, linear/angular dual-mode programmability, stray-field immune operation capability, and ISO 26262 SEooC ASIL-C functional safety support.
Technical Context
The MLX90373KVS-ABA-300-RX integrates a Triaxis® Hall sensor array with on-chip DSP to decode BX, BY, and BZ magnetic field components for absolute position reconstruction. Its -30x option code enables legacy linear/rotary mode with 11–20 mT useful magnetic field norm and 0.05–0.2° noise (±3σ, filter-dependent).
It implements 2-wire PSI5 communication over supply lines with 300–500 µs cycle time, supports programmable transfer characteristics (4/8-point piecewise-linear or 17/32-point PWL), and includes integrated diagnostics including intelligent watchdog (20 ms timeout) and configurable analog/digital diagnostic cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +125°C - Validated for under-hood automotive environments without derating. |
| PSI5 Compliance | v1.3 & v2.1 - Enables direct connection to ECU PSI5 receivers without external level-shifting or protocol translation. |
| Angle Accuracy | ±0.85° total drift (XY mode) - Specifies maximum deviation from calibrated angle across temperature and lifetime, referenced to 35°C. |
| Magnetic Range | 11–20 mT useful field norm - Defines minimum/maximum usable BNORM for nominal accuracy in legacy linear/rotary mode (-30x). |
| Supply Voltage | 4.1–6 V (PSI5 active) - Compatible with standard 5 V automotive supply rails; supports undervoltage lockout at 3.7–4.1 V. |
| Quiescent Current | 9–12.5 mA - Power budget impact for always-on position sensing in battery-constrained systems. |
| Stray Field Immunity | Up to 5 mT (4 kA/m) - Meets ISO 11452-8 for robust operation near high-current actuators or motors. |
Pinout & Package
DMP-4 package: Dual-mold, PCB-less, 4-terminal surface-mount module with straight leads (STD1), RoHS compliant. Dimensions: 4.0 × 3.0 × 1.1 mm (L×W×H). No internal PCB; terminals are directly bonded to die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be connected to low-impedance system ground plane. |
| 2 | VDD | Supply input and PSI5 data output line; requires 4.1–6 V; carries modulated current signal during PSI5 frame transmission. |
| 3 | N.C. | No internal connection; electrically isolated; recommended to tie to ground for EMC stability. |
| 4 | VSS | Second ground terminal; improves thermal dissipation and reduces ground loop impedance in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of BX, BY, BZ enables true 3D magnetic field decoding for absolute position without mechanical cam or gear constraints. |
| Programmable Transfer Curve | Supports 4/8-point piecewise-linear or 17/32-point PWL calibration - allows precise linearization of non-ideal magnet trajectories in custom mechanical assemblies. |
| AEC-Q100 Grade 0 | Qualified for -40°C to +125°C ambient operation - eliminates need for external thermal derating in engine bay or transmission control applications. |
| ISO 26262 SEooC ASIL-C | Delivers certified functional safety mechanisms (watchdog, ECC, diagnostics) - reduces integration effort for ASIL-B/C system-level safety goals. |
| Stray-Field Immune Mode | Valid for -10x variants only; MLX90373KVS-ABA-300-RX uses legacy mode but shares same core architecture enabling field upgrade path. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371KGO-ABA-300-RE | TSSOP-16 dual-die redundant package; higher quiescent current (2×); isolation resistance >4 MΩ between dice. | Required for ASIL-D system partitioning where hardware redundancy is mandated; not drop-in due to pin count and layout change. | Select when functional safety architecture requires physically independent signal paths and fault containment. |
| MLX90393ELQ-ABA-000-SP | 3-axis Hall sensor with I²C/SPI output; no integrated PSI5; 20-bit resolution; wider magnetic range (±50 mT). | Suitable for non-automotive industrial position feedback where protocol flexibility and higher resolution outweigh PSI5 integration. | Choose when host MCU has available I²C/SPI peripherals and system-level timing allows software-driven polling instead of deterministic PSI5 frames. |
Compared with MLX90373KVS-ABA-300-RX, the MLX90371KGO-ABA-300-RE adds hardware redundancy at the cost of board area and power, while the MLX90393ELQ-ABA-000-SP trades PSI5 integration for interface flexibility and higher raw resolution-neither is pin-compatible, and both require PCB redesign and firmware adaptation.

FAQ
What is the operating temperature range for the MLX90373KVS-ABA-300-RX?
The MLX90373KVS-ABA-300-RX is rated for continuous operation from -40°C to +125°C ambient temperature. This range is validated per AEC-Q100 Grade 0 requirements and applies to all electrical and magnetic specifications in the datasheet, including angle accuracy, PSI5 timing, and quiescent current. Operation outside this range may result in undefined behavior or permanent damage.
Does the MLX90373KVS-ABA-300-RX support PSI5 v2.1 communication?
Yes, the MLX90373KVS-ABA-300-RX fully supports PSI5 v2.1 protocol in addition to v1.3. It implements 2-wire current modulation over the VDD line with cycle times from 300 µs to 500 µs, synchronous and asynchronous modes, and built-in error reporting. The device auto-negotiates frame structure based on ECU command and maintains backward compatibility with legacy PSI5 receivers.
What package type is used by the MLX90373KVS-ABA-300-RX?
The MLX90373KVS-ABA-300-RX uses the DMP-4 (Dual Mould Package) - a PCB-less, 4-terminal surface-mount module with straight leads (STD1 configuration). Its dimensions are 4.0 × 3.0 × 1.1 mm, and it features two ground terminals (Pins 1 and 4), one supply/data terminal (Pin 2), and one no-connect terminal (Pin 3) tied to ground for EMC.
Can the MLX90373KVS-ABA-300-RX be used in stray-field immune applications?
No - the MLX90373KVS-ABA-300-RX is configured for legacy linear/angular mode (-30x option code), which does not activate the stray-field immune algorithm. That feature is exclusive to -10x variants (e.g., MLX90373KVS-ABA-100-RX). While the underlying Triaxis® silicon is identical, the firmware and magnetic processing path are fixed at factory programming and cannot be reconfigured in-system.
What is the total angle drift specification for the MLX90373KVS-ABA-300-RX?
The MLX90373KVS-ABA-300-RX exhibits a maximum total angle drift of ±0.85° in XY mode under nominal performance conditions, referenced to 35°C and measured across -40°C to +125°C after end-of-line calibration. This value includes contributions from temperature coefficient, aging, and mechanical stress effects, and assumes use within specified magnetic field norms (11–20 mT) and filtering settings.
