Product details

Overview

MLX90373KVS-ABA-100-SP from Melexis is a Triaxis® Hall-based absolute rotary position processor IC for stray-field immune angular sensing, delivering 12-bit PSI5 output with ±0.85° total angle drift over −40°C to +125°C, 0–360° measurement range, and robustness against 4 kA/m stray fields per ISO 11452-8. It targets automotive pedal, throttle, and steering wheel position sensing in safety-critical systems.

For engineers reviewing the MLX90373KVS-ABA-100-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 package compatibility, -100 option code for stray-field immune rotary mode, AEC-Q100 Grade 0 qualification, ISO 26262 SEooC ASIL-C compliance, and 500 µs PSI5 cycle time.

Technical Context

The MLX90373KVS-ABA-100-SP implements Triaxis® Hall sensing with on-chip IMC (Integrated Magnetic Concentrator) to resolve all three magnetic field components (B_X, B_Y, B_Z) and compute absolute angle via digital signal processing. Its -100 option code configures it exclusively for stray-field immune rotary mode using magnetic gradient ∆B_XY/∆XY as the useful signal.

This variant operates with 2-wire PSI5 v1.3/v2.1 communication at 6–18 V supply, delivers latency of 850 µs and worst-case step response of 2125 µs, and embeds programmable diagnostics, multi-point linearization (up to 32 points), and 48-bit ID - all validated under AEC-Q100 Grade 0 and ISO 26262 ASIL-C functional safety requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	6–18 V - supports direct connection to automotive battery rail without external regulator.
Quiescent Current	10–13.5 mA - enables low-power operation in always-on vehicle subsystems.
PSI5 Cycle Time	300–500 µs - ensures high update rate for real-time closed-loop control in ECU applications.
Angle Accuracy	±0.85° total drift - guaranteed over full temperature range and lifetime, critical for ASIL-C system compliance.
Stray Field Immunity	Up to 4 kA/m (5 mT) - maintains accuracy in magnetically noisy engine bay environments per ISO 11452-8.
Operating Temp	−40°C to +125°C - meets under-hood automotive ambient requirements without derating.
Output Protocol	2-wire PSI5 v1.3/v2.1 - enables daisy-chainable, noise-immune communication over supply line.

Pinout & Package

DMP-4 package: dual-mold, PCB-less, 4-terminal surface-mount device with straight leads (STD1 configuration), RoHS compliant, optimized for compact, high-reliability automotive sensor assemblies.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute rotary position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90373KGO-ABA-100-RE	TSSOP-16 dual-die redundant package with isolation resistance >4 MΩ between dice; higher quiescent current (2×10–13.5 mA); requires separate ground routing.	Required where hardware-level redundancy is mandated (e.g., ASIL-D subsystems); not suitable for space-constrained DMP-4 footprints.	Select when functional safety architecture demands physical die separation and fault containment - not a drop-in replacement for MLX90373KVS-ABA-100-SP.
MLX90371KDC-ABA-100-RE	SOIC-8 single-die package; same -100 stray-field immune mode but lacks 48-bit ID and advanced diagnostics; lower EMC immunity margin.	Suitable for cost-sensitive non-safety applications (e.g., HVAC flap control); not AEC-Q100 Grade 0 qualified.	Choose only for legacy designs where DMP-4 footprint is unavailable and ASIL-C compliance is not required.

Compared with MLX90373KGO-ABA-100-RE and MLX90371KDC-ABA-100-RE, the MLX90373KVS-ABA-100-SP uniquely balances DMP-4 miniaturization, full ASIL-C capability, and stray-field immunity - making it the only option for new compact, safety-certified automotive rotary sensing designs.

FAQ

What is the operating temperature range of the MLX90373KVS-ABA-100-SP?

The MLX90373KVS-ABA-100-SP operates from −40°C to +125°C, fully qualified per AEC-Q100 Grade 0. This range covers under-hood automotive environments including engine compartments and transmission control units, with no performance derating required across the span. The device's total angle drift specification (±0.85°) is guaranteed over this entire range.

Does the MLX90373KVS-ABA-100-SP support PSI5 v2.1 communication?

Yes, the MLX90373KVS-ABA-100-SP natively supports both PSI5 v1.3 and v2.1 protocols over its 2-wire interface. It uses current modulation on the VDD line with configurable cycle times (300–500 µs), frame structure, and error reporting modes - enabling seamless integration into modern automotive domain controllers compliant with latest PSI5 standards.

How does the stray-field immunity of the MLX90373KVS-ABA-100-SP work?

The MLX90373KVS-ABA-100-SP achieves stray-field immunity by using the magnetic gradient ∆B_XY/∆XY - not absolute field strength - as its primary sensing signal. This allows it to reject uniform stray fields up to 4 kA/m (5 mT) per ISO 11452-8 while maintaining ±0.6° output error, making it ideal for placement near motors, solenoids, or high-current traces.

Is the MLX90373KVS-ABA-100-SP pin-compatible with other MLX90373 variants?

No - the MLX90373KVS-ABA-100-SP uses the DMP-4 package with 4 terminals, while SOIC-8 and TSSOP-16 variants have different pin counts, layouts, and internal die configurations. Direct PCB replacement is not possible; layout redesign is required to migrate between packages, even within the same MLX90373 family.

What calibration options are available for the MLX90373KVS-ABA-100-SP?

The MLX90373KVS-ABA-100-SP supports end-user programmable transfer characteristics: 4-point, 8-point, or 17-/32-point piecewise-linear calibration. These are written via PTC (Programming Through Connector) and stored in NVRAM, enabling compensation for magnet nonlinearity, mechanical tolerances, and thermal drift - all without modifying host ECU firmware.
