Product details

Overview

MLX90373KVS-ABA-100-RX from Melexis is a Triaxis® Hall-based absolute position processor IC in DMP-4 package, delivering stray-field immune angular position sensing up to 180° with ±0.85° total angle drift over -40°C to +125°C, 2-wire PSI5 v1.3/v2.1 output, and AEC-Q100 Grade 0 qualification for automotive pedal and throttle position sensing.

For engineers reviewing the MLX90373KVS-ABA-100-RX datasheet, pinout, applications, or equivalent options, key selection criteria include its DMP-4 4-pin footprint, PSI5 current-modulated interface, 1480–2125 µs worst-case step response, and immunity to 4 kA/m stray fields per ISO 11452-8.

Technical Context

The MLX90373KVS-ABA-100-RX implements Triaxis® sensing architecture that simultaneously measures B_X, B_Y, and B_Z magnetic field components to compute absolute angular position from magnet motion. Its stray-field immune mode (-100 option code) relies on in-plane magnetic gradient (∆B_XY/∆XY) as the primary signal, rejecting uniform external fields up to 5 mT.

It integrates on-chip DSP for real-time angle calculation, programmable multi-point linearization (4/8/17/32 points), and dual-stage watchdogs (IWD/AWD). The device operates on a single 2-wire PSI5 bus with supply/communication combined on VDD/PSI5-OUT, requiring no separate data line or ground return for signal transmission.

Key Specifications

Parameter	Value and Actual Design Meaning
Position Sensing Mode	Stray-field immune rotary (0–180°), using ∆B_XY/∆XY gradient as primary signal
Output Interface	2-wire PSI5 v1.3/v2.1 with current modulation; no separate data line required
Total Angle Drift	±0.85° over -40°C to +125°C (relative to 35°C), post-calibration
Stray Field Immunity	Valid up to 4 kA/m (5 mT) per ISO 11452-8; enables operation in high-EMI engine bays
Supply Voltage Range	6–18 V during PSI5 communication; supports wide automotive battery variation
Quiescent Current	10–13.5 mA typical for stray-field immune mode; enables low-power ECU integration
Step Response Time	1480–2125 µs worst case; determines minimum detectable angular slew rate

Pinout & Package

DMP-4 is a PCB-less dual-mold package with 4 terminals, optimized for direct solder-mounting onto flexible or rigid substrates. It features straight leads (STD1 configuration per ordering code -100) and RoHS compliance.

Pin/Terminal	Circuit Role	Design Meaning
1	VSS	Ground reference for analog/digital circuitry; must be connected to PCB ground plane
2	VDD	Combined supply input and PSI5 current-output node; powers IC and carries modulated data
3	N.C.	No internal connection; must be left unconnected per datasheet guidance
4	VSS	Second ground terminal for improved EMC performance and thermal dissipation

Key Features

Feature	Design Value
Triaxis® Hall Sensing	Simultaneous B_X, B_Y, B_Z measurement enables robust absolute angle decoding without mechanical stops or gears
Stray-Field Immunity	Rejects uniform external magnetic interference up to 4 kA/m while maintaining <0.6° error - critical for EV powertrain proximity
Programmable Transfer Characteristic	Supports 4-, 8-, 17-, or 32-point piecewise-linear calibration to compensate for magnet nonlinearity and mechanical tolerances
AEC-Q100 Grade 0	Qualified for operation from -40°C to +125°C ambient, meeting automotive powertrain and chassis requirements
ISO 26262 SEooC ASIL-C	Delivers safety mechanisms (dual watchdogs, ECC memory, diagnostics) as a Safety Element out of Context for system-level ASIL decomposition

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90373KGO-ABA-100-RE	TSSOP-16 dual-die redundant package; isolated dice; higher quiescent current (2×)	Required for ASIL-D decomposition or full functional redundancy in steer-by-wire	Select when hardware redundancy or die-level isolation is mandated by safety architecture
MLX90373KDC-ABA-100-RE	SOIC-8 single-die package; 8-pin footprint; different pinout and decoupling scheme	Suitable for legacy PCB layouts or cost-sensitive non-redundant modules	Select when SOIC-8 compatibility or lower unit cost outweighs DMP-4's space savings

Compared with MLX90373KVS-ABA-100-RX, the TSSOP-16 alternative provides die-level redundancy for ASIL-D systems but doubles supply current and increases board area, while the SOIC-8 version retains identical sensing performance but requires layout revision and lacks DMP-4's direct-mount flexibility.

FAQ

What is the primary magnetic sensing principle used by the MLX90373KVS-ABA-100-RX?

The MLX90373KVS-ABA-100-RX uses Triaxis® Hall technology to measure all three orthogonal components (B_X, B_Y, B_Z) of the applied magnetic field. In its -100 configuration, it computes absolute angular position from the in-plane magnetic gradient (∆B_XY/∆XY), enabling stray-field immunity up to 4 kA/m per ISO 11452-8. This principle eliminates sensitivity to uniform external fields while preserving accuracy in dynamic mechanical environments.

How does the MLX90373KVS-ABA-100-RX interface with an ECU over PSI5?

The MLX90373KVS-ABA-100-RX uses a true 2-wire PSI5 v1.3/v2.1 interface where VDD serves as both power supply and current-modulated data line. It draws supply current proportional to the encoded position value, eliminating the need for a separate data wire or ground return path. The device supports configurable cycle times (300–500 µs), synchronization pulses, and diagnostic reporting modes compatible with standard automotive PSI5 receivers.

What is the significance of the "-100" option code in MLX90373KVS-ABA-100-RX?

The "-100" option code specifies the MLX90373KVS-ABA-100-RX as configured for Angular Rotary Stray-Field Immune operation in DMP-4 packaging. The first digit "1" denotes stray-field immune magnetic configuration; the second digit "0" indicates default factory programming; the third digit "0" selects standard straight leads (STD1) for the DMP-4 package. This configuration enables 0–180° absolute angle measurement with guaranteed immunity to 4 kA/m external fields.

Can the MLX90373KVS-ABA-100-RX be reprogrammed in-system?

Yes, the MLX90373KVS-ABA-100-RX supports end-user programmability via PTC (Programming Through Connector) using the Melexis PTCSW software suite. Users can configure transfer characteristics (4/8/17/32-point PWL), filter settings, diagnostics thresholds, and identification data. Reprogramming requires only the PSI5 bus and a compatible programming tool - no additional pins or interfaces are needed, preserving the 4-terminal DMP-4 footprint.

What are the thermal and environmental qualifications of the MLX90373KVS-ABA-100-RX?

The MLX90373KVS-ABA-100-RX is AEC-Q100 qualified Grade 0 (−40°C to +125°C ambient), ISO 26262 SEooC ASIL-C certified, and compliant with RoHS and REACH. It meets stringent automotive EMC requirements including ISO 11452-8 for stray magnetic field immunity and supports operation in high-humidity, vibration-prone under-hood environments. Its DMP-4 package is rated for reflow soldering per J-STD-020 and qualified for 1000+ thermal cycles.
