Product details
Overview
MLX90373KVS-ABA-300-SP 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 targets automotive pedal, throttle, and ride height sensing.
For engineers reviewing the MLX90373KVS-ABA-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include DMP-4 package compatibility, PSI5 communication timing (300–500 µs cycle), programmable 4/8/17/32-point transfer characteristic, AEC-Q100 Grade 0 qualification, and ISO 26262 SEooC ASIL-C functional safety compliance.
Technical Context
The MLX90373KVS-ABA-300-SP implements Triaxis® technology to measure all three magnetic field components (BX, BY, BZ) simultaneously, enabling robust absolute position decoding in both linear and angular configurations. Its on-chip DSP performs real-time signal processing including multi-point linearization, filtering (FIR/EMA), and diagnostics.
It uses a 24 MHz main clock (±5% tolerance) with 850 µs latency and 1480–2125 µs worst-case step response in default configuration. The device supports PSI5 current modulation over supply lines with programmable cycle time (300–500 µs), synchronization pulse hold time (9 µs), and error reporting modes compliant with v1.3 and v2.1 standards.
Key Specifications

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 architecture; higher quiescent current (2×10.5 mA); isolation resistance >4 MΩ between dies. | Targeted at ASIL-D systems requiring full hardware redundancy; larger footprint and higher cost than DMP-4. | Select when functional safety requirements exceed ASIL-C or fault-tolerant dual-channel validation is mandated. |
| MLX90372KVS-ABA-300-SP | DMP-4 package; identical pinout and PSI5 interface; lacks ISO 26262 SEooC certification and AEC-Q100 Grade 0 qualification. | Suitable for industrial or consumer applications where automotive reliability and safety certification are not required. | Choose for cost-sensitive designs needing same form factor and basic functionality without automotive-grade validation. |
Compared with MLX90373KVS-ABA-300-SP, the MLX90371KGO-ABA-300-RE adds die-level redundancy for ASIL-D but increases board area and power; the MLX90372KVS-ABA-300-SP shares mechanical and electrical compatibility but omits safety certifications and high-temp validation, limiting deployment to non-automotive use cases.

FAQ
What is the operating voltage range for MLX90373KVS-ABA-300-SP during PSI5 communication?
The MLX90373KVS-ABA-300-SP operates from 6 V to 18 V during PSI5 communication when used in DMP-4 or SOIC-8 packages. This wide supply range accommodates battery transients and ensures reliable operation in automotive 12 V systems. The device also features undervoltage lockout thresholds (3.70–4.10 V) and overvoltage protection up to 37 V for short durations.
Does MLX90373KVS-ABA-300-SP support both linear and angular position sensing?
Yes, MLX90373KVS-ABA-300-SP supports both linear and angular position sensing through its option code "-300", which configures the device for Legacy/Linear Position or Legacy/Angular Rotary modes. It uses Triaxis® technology to decode magnet motion in either configuration without hardware change, relying solely on magnetic circuit design and end-user programming of the transfer characteristic.
What package type is used by MLX90373KVS-ABA-300-SP and what are its mounting advantages?
MLX90373KVS-ABA-300-SP uses the DMP-4 (Dual Mould Package) - a PCB-less, 4-terminal surface-mount package with straight leads. Its advantages include minimal footprint (no substrate), direct solderability to flex or rigid boards, improved thermal coupling to PCB, and suitability for automated assembly in space-constrained automotive modules like pedal sensors and throttle bodies.
How does MLX90373KVS-ABA-300-SP achieve stray magnetic field immunity?
MLX90373KVS-ABA-300-SP achieves stray-field immunity up to 5 mT (4 kA/m) by leveraging Triaxis® technology to compute position from the spatial gradient of the magnetic field (∆BXY/∆XY) rather than absolute field magnitude. This differential method rejects uniform external fields while preserving sensitivity to the intended magnet's localized gradient, validated per ISO 11452-8 test methodology.
Is MLX90373KVS-ABA-300-SP certified for automotive functional safety standards?
Yes, MLX90373KVS-ABA-300-SP is certified to ISO 26262 SEooC ASIL-C and AEC-Q100 Grade 0. These qualifications confirm its suitability for safety-critical automotive applications such as electronic throttle control and brake-by-wire subsystems, with documented safety mechanisms including CRC, ECC, dual watchdogs, and diagnostic coverage reports available in the official safety manual.
