Product details

Overview

MLX90373KVS-ABA-300-RE from Melexis is a Triaxis® Hall-based absolute position processor IC in DMP-4 package, delivering linear or angular position output via 2-wire PSI5 v1.3/v2.1 interface, with ±0.85° total angle drift over −40°C to +125°C, AEC-Q100 Grade 0 qualification, and stray-field immunity up to 5 mT (4 kA/m) per ISO 11452-8 - used in throttle, pedal, and ride height sensing.

For engineers reviewing the MLX90373KVS-ABA-300-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, PSI5 timing constraints, magnetic field gradient sensitivity (0.075–0.125 mT/mm), dual-ground DMP-4 terminal mapping, and validated alternatives for linear/angular position sensing in automotive ASIL-C systems.

Technical Context

The MLX90373KVS-ABA-300-RE implements Triaxis® Hall sensing of B_X, B_Y, and B_Z flux components to compute absolute position from magnet motion, supporting both legacy linear/rotary modes (−30x option code) and programmable multi-point transfer characteristics (4/8/17/32 points). Its on-chip DSP performs real-time angle calculation, filtering, and diagnostics without external MCU intervention.

It operates in PSI5 synchronous mode with 300–500 µs cycle time, delivers 12-bit position data per frame, and integrates ISO 26262 SEooC ASIL-C safety mechanisms including dual watchdogs (IWD/AWD), ECC-protected NVRAM, and configurable diagnostics. The DMP-4 package enables PCB-less mounting with 2.54 mm straight leads and dual VSS terminals for low-impedance grounding.

Key Specifications

Parameter	Value and Actual Design Meaning
Position Output Protocol	2-wire PSI5 v1.3/v2.1 over supply line; no separate data line required - reduces wiring complexity and EMI susceptibility.
Operating Temperature Range	−40°C to +125°C - qualified for under-hood automotive environments without derating.
Angle Accuracy (Total Drift)	±0.85° max over full temperature range and lifetime - specified after calibration, includes thermal and aging effects.
Magnetic Sensitivity	0.075–0.125 mT/mm field gradient resolution (12-bit) - enables high-resolution linear displacement or rotary position detection.
Stray-Field Immunity	Robust to 5 mT (4 kA/m) external fields per ISO 11452-8 - maintains <0.6° error under worst-case stray-field interference.
Supply Voltage Range	6–18 V during PSI5 communication - compatible with 12 V automotive battery systems including load-dump transients.
Quiescent Current	9–12.5 mA (legacy mode) - optimized for always-on vehicle subsystems with strict power budgets.

Pinout & Package

DMP-4 is a dual-mold, PCB-less package with 4 terminals: two ground (VSS), one supply/PSI5-output (VDD), and one not-connected (N.C.). Designed for direct solder-mounting onto flex or rigid boards with 2.54 mm pitch and straight leads (STD1 configuration per option code -300).

Pin/Terminal	Circuit Role	Design Meaning
1	VSS	Primary ground reference; must be connected to low-impedance chassis or system ground to ensure EMC compliance and signal integrity.
2	VDD	Supply input and PSI5 data output node; carries bidirectional current-modulated PSI5 frames - requires 6–18 V with ≤13.5 mA quiescent draw.
3	N.C.	No internal connection; must remain unconnected per datasheet - floating or tied to ground may disrupt internal biasing.
4	VSS	Secondary ground terminal; used for star-grounding topology to minimize ground loop noise in high-EMI environments.

Key Features

Feature	Design Value
Triaxis® Hall Sensing	Simultaneous measurement of B_X, B_Y, B_Z enables true 3D magnetic field decoding - eliminates need for external concentrators or multi-sensor assemblies.
Programmable Transfer Characteristic	Configurable 4-, 8-, 17-, or 32-point piecewise-linear curve - supports custom mechanical stroke profiles without firmware changes.
PSI5 v2.1 Compliance	Full support for synchronization pulses, error reporting, and diagnostic frames - interoperable with modern ECU PSI5 receivers without protocol translation.
AEC-Q100 Grade 0 & ISO 26262 SEooC ASIL-C	Validated for safety-critical automotive functions up to 125°C ambient - includes hardware-level fault detection and safe state outputs.
Stray-Field Immune Angle Sensing	Maintains <0.6° accuracy under 4 kA/m stray fields - enables reliable operation near motors, solenoids, or high-current cables.

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 (2×12.5 mA); isolation resistance >4 MΩ between dice.	Required for ASIL-D systems needing hardware redundancy; larger footprint and higher cost than DMP-4.	Select when functional safety demands dual-channel independence - not drop-in compatible due to pin count and package size.
MLX90372KVS-ABA-300-RE	DMP-4 package same as MLX90373KVS-ABA-300-RE but uses SENT output instead of PSI5; lacks ISO 26262 SEooC certification.	Suitable for non-safety-critical applications where SENT infrastructure exists; no PSI5 receiver compatibility.	Choose only if existing ECU supports SENT and ASIL-C is not mandated - differs in protocol, safety scope, and diagnostic depth.

Compared with MLX90373KVS-ABA-300-RE, the MLX90371KGO-ABA-300-RE adds hardware redundancy at the cost of size and power, while the MLX90372KVS-ABA-300-RE trades PSI5+ASIL-C for SENT simplicity - neither is pin-compatible, and all three require distinct ECU interface design.

What is the PSI5 timing behavior of MLX90373KVS-ABA-300-RE in default configuration?

In default configuration with no filtering, the MLX90373KVS-ABA-300-RE exhibits 850 µs latency and 1480–2125 µs worst-case step response time (Table 10). Cycle time is fixed at 300–500 µs, bit time at 5–8.4 µs, and sync pulse hold time at ≥9 µs - all compliant with PSI5 v2.1 for deterministic ECU synchronization.

Is MLX90373KVS-ABA-300-RE qualified for automotive safety standards?

Yes, the MLX90373KVS-ABA-300-RE is AEC-Q100 Grade 0 qualified and certified as a Safety Element out of Context (SEooC) meeting ISO 26262 ASIL-C requirements.
