Product details
Overview
MLX90373KVS-ABA-303-RE from Melexis is a Triaxis® position processor IC for absolute linear and angular position sensing using 3-axis Hall technology, delivering 12-bit PSI5 output with ±0.45° total angular drift (–40°C to 125°C), AEC-Q100 Grade 0 qualification, and stray-field immunity up to 5 mT - deployed in automotive throttle and pedal position systems.
For engineers reviewing the MLX90373KVS-ABA-303-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), PSI5 v1.3/v2.1 timing compliance, magnetic field gradient sensitivity (0.075–0.125 mT/mm), programmable transfer characteristics (4/8/17/32-point PWL), and ISO 26262 SEooC ASIL-C functional safety architecture.
Technical Context
The MLX90373KVS-ABA-303-RE implements Triaxis® Hall sensing with on-chip DSP for absolute position decoding from BX, BY, BZ flux components, supporting both legacy angular/linear modes (–30x option code) and configurable multi-point transfer functions. Its DMP-4 package integrates dual-mold PCB-less construction with 4-terminal layout optimized for 2-wire PSI5 communication over supply lines.
It features integrated diagnostics including intelligent watchdog (20 ms timeout), absolute watchdog (20 ms), analog/digital diagnostic cycles (9.3–20 ms), and programmable magnetic field monitoring (BTH_LOW/BTH_HIGH thresholds). The device operates across 4.1–6 V supply (PSI5 mode) and achieves <5 ms start-up time with full diagnostics enabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (PSI5) | 4.1–6 V - defines minimum operating headroom for reliable 2-wire current-modulated PSI5 signaling without external regulation |
| Quiescent Current | 9–12.5 mA - determines system-level power budget for continuous position reporting in automotive ECU environments |
| Angular Accuracy (Total Drift) | ±0.45° - maximum deviation after calibration across –40°C to 125°C, enabling high-fidelity pedal/throttle control loops |
| PSI5 Cycle Time | 300–500 µs - sets deterministic sensor update rate for real-time closed-loop actuation (e.g., 2 kHz frame rate at 500 µs) |
| Stray-Field Immunity | Up to 5 mT (4 kA/m) - ensures robust operation in high-EMI engine bays per ISO 11452-8 without shielding |
| Output Resolution | 12-bit PSI5 data - provides 0.088° angular granularity over 360°, sufficient for ASIL-C–compliant motion control |
| Functional Safety | ISO 26262 SEooC ASIL-C - certifies internal diagnostics (CRC, ECC, watchdogs, memory tests) for integration into safety-critical vehicle subsystems |
Pinout & Package
DMP-4 package: Dual Mold Package, PCB-less, 4-terminal surface-mount construction with straight leads (STD2 2.54 mm pitch per ordering legend).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains; must be connected to PCB ground plane for EMC compliance |
| 2 | VDD | Supply input and PSI5 data output line - enables 2-wire bidirectional communication without dedicated data pins |
| 3 | N.C. | No internal connection; electrically isolated and must be tied to ground per EMC best practice |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground impedance in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Hall Sensing | Enables absolute position decoding from BX, BY, BZ components - eliminates need for external magnets with complex pole arrangements |
| Programmable Transfer Characteristic | Supports 4/8-point linear or 17/32-point piecewise-linear calibration - allows precise compensation of mechanical nonlinearity in throttle linkages |
| PSI5 v1.3 & v2.1 Compliance | Guarantees interoperability with standard automotive sensor hubs without protocol translation or firmware adaptation |
| Stray-Field Immune Operation | Maintains ±0.6° accuracy under 4 kA/m stray fields - critical for placement near motors, solenoids, or high-current cables |
| End-of-Line Programmability | Allows post-manufacturing calibration and configuration via PTC - supports flexible production test and vehicle-specific tuning |
