Product details
Overview
MLX90373KVS-ABA-103-SP from Melexis is a Triaxis® Hall-based absolute position processor IC in DMP-4 package, delivering stray-field immune angular position sensing up to 360° with PSI5 v1.3/v2.1 output, ±0.85° total angle drift over -40°C to +125°C, and AEC-Q100 Grade 0 qualification - used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90373KVS-ABA-103-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its 2-wire PSI5 interface, 4-pin DMP-4 footprint, stray-field immunity up to 5 mT, programmable piecewise-linear transfer characteristic, and ISO 26262 SEooC ASIL-C compliance for safety-critical systems.
Technical Context
The MLX90373KVS-ABA-103-SP implements Triaxis® Hall sensing with on-chip IMC (Integrated Magnetic Concentrator) to resolve all three magnetic field components (BX, BY, BZ), enabling robust absolute angle decoding from rotating or linear magnets. Its architecture supports two primary modes: Rotary Stray-Field Immune (-10x option code) and Legacy Angular/Linear (-30x), with this variant configured for the former.
It uses a 24 MHz internal main clock (±5% tolerance including thermal drift), processes data via integrated DSP, and outputs synchronized PSI5 frames with configurable cycle time (300–500 µs). Latency is 850 µs and worst-case step response is 2125 µs in default configuration without filtering - critical for real-time closed-loop control in ECU applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 6–18 V during PSI5 communication - supports wide automotive battery range with reverse voltage protection to -14 V. |
| Quiescent Current | 10–13.5 mA at -40°C to +125°C - enables low-power operation in always-on vehicle subsystems. |
| PSI5 Interface | v1.3 and v2.1 compliant, 2-wire current-modulated protocol - eliminates need for separate data line and simplifies wiring harness. |
| Stray-Field Immunity | Robust to 5 mT (4 kA/m) external fields per ISO 11452-8 - ensures reliable operation near motors, solenoids, or high-current traces. |
| Angle Accuracy | ±0.85° total drift over temperature and lifetime - meets tight mechanical tolerance requirements in pedal and throttle actuation. |
| Operating Temperature | -40°C to +125°C ambient - qualified for under-hood and transmission-mounted automotive locations. |
| Functional Safety | ISO 26262 SEooC ASIL-C certified - provides documented safety mechanisms for integration into ASIL-B/C system architectures. |
Pinout & Package
Dual Mold Package (DMP-4), PCB-less, RoHS-compliant, with 4 leads: 2×VSS (ground), 1×VDD (supply/PSI5-OUT), and 1×NC (not connected). Designed for direct solder-mounting onto flexible or rigid PCBs with minimal footprint and no substrate.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground return path for analog and digital circuitry - must be connected to PCB ground plane for EMC stability. |
| 2 | VDD | Supply input and PSI5 data output node - carries both power and modulated current signal; requires external decoupling. |
| 3 | N.C. | No internal connection - must remain unconnected per datasheet; floating or tied to ground degrades PSI5 signal integrity. |
| 4 | VSS | Second ground terminal - improves current return path symmetry and reduces common-mode noise in 2-wire PSI5 loop. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of BX, BY, BZ enables true 3D magnetic field reconstruction - eliminates reliance on single-axis magnet orientation. |
| Programmable Transfer Characteristic | Supports 4-, 8-, 17-, or 32-point piecewise-linear calibration - allows precise compensation of non-ideal magnetic circuits and mechanical hysteresis. |
| Stray-Field Immune Mode | Uses magnetic gradient ∆BXY/∆XY as primary signal - rejects uniform external fields while preserving sensitivity to target magnet motion. |
| AEC-Q100 Grade 0 Qualification | Validated for 125°C ambient operation with HTOL, TC, and ESD testing - ensures reliability in engine compartment and transmission control units. |
| 48-bit Unique ID | Factory-programmed serial number enables traceability, secure firmware binding, and anti-counterfeit verification in production ECUs. |

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-103-RE | TSSOP-16 dual-die redundant package with isolation >4 MΩ between dies - higher fault coverage but larger footprint and 2× supply current. | Required for ASIL-D systems needing hardware redundancy; not suitable for space-constrained DMP-4 mounting. | Select when full functional safety redundancy is mandated and PCB area permits TSSOP-16 layout. |
| MLX90373KDC-ABA-103-RE | SOIC-8 single-die package with identical electrical specs but different pinout (8 pins vs. 4) and no trim-and-form lead options. | Suitable for legacy board designs with SOIC footprints; lacks DMP-4's ultra-low profile and flexible mounting. | Choose for compatibility with existing SOIC-8 layouts where DMP-4 mechanical integration is impractical. |
Compared with MLX90373KGO-ABA-103-RE and MLX90373KDC-ABA-103-RE, the MLX90373KVS-ABA-103-SP offers the smallest form factor and lowest assembly cost for new designs requiring stray-field immune angular sensing without hardware redundancy - ideal for cost-sensitive, space-constrained automotive modules.

FAQ
What is the primary magnetic sensing mode supported by the MLX90373KVS-ABA-103-SP?
The MLX90373KVS-ABA-103-SP operates in Rotary Stray-Field Immune mode (indicated by option code "-103"), using the magnetic field gradient ∆BXY/∆XY as its primary signal. This enables accurate angular position measurement while rejecting uniform external magnetic interference up to 5 mT, making it ideal for environments with motors or high-current conductors. The MLX90373KVS-ABA-103-SP does not support Legacy Linear or XZ/YZ modes unless reprogrammed - its factory configuration is fixed to stray-field immune rotary operation.
Does the MLX90373KVS-ABA-103-SP require an external microcontroller to function?
No, the MLX90373KVS-ABA-103-SP is a fully self-contained position processor with integrated ADC, DSP, and PSI5 transmitter - no external MCU is needed for basic operation. It performs on-chip signal conditioning, linearization, and communication encoding. However, programming of calibration points, diagnostics, or safety parameters requires a PTC (Programming Through Connector) interface and Melexis-provided tools. The MLX90373KVS-ABA-103-SP delivers ready-to-use position data over its 2-wire PSI5 output.
What is the maximum operating supply voltage for the MLX90373KVS-ABA-103-SP during PSI5 communication?
The MLX90373KVS-ABA-103-SP supports a maximum PSI5 operating supply voltage of 18 V for durations under 24 hours at junction temperatures below 175°C, as specified in its Absolute Maximum Ratings table. For continuous operation, the recommended supply range is 6–12 V. Exceeding 18 V risks permanent damage, and operation above 12 V should only occur transiently during load dump events - the MLX90373KVS-ABA-103-SP includes built-in undervoltage and overvoltage detection to flag out-of-spec conditions.
Can the MLX90373KVS-ABA-103-SP be used for linear position sensing?
Yes, the MLX90373KVS-ABA-103-SP can be configured for linear position sensing using appropriate magnet geometry and magnetic circuit design, though its factory option code "-103" configures it for Rotary Stray-Field Immune operation. Linear use requires end-user programming of the transfer characteristic and validation of magnetic field gradient linearity. The MLX90373KVS-ABA-103-SP's underlying Triaxis® architecture supports both rotary and linear modalities - confirmed in Melexis' Application Examples and Functional Diagram sections.
Is the MLX90373KVS-ABA-103-SP pin-compatible with other MLX90373 variants like the SOIC-8 or TSSOP-16 packages?
No, the MLX90373KVS-ABA-103-SP uses the DMP-4 package with a unique 4-pin layout (VSS-VDD-N.C.-VSS), which is not pin-compatible with the SOIC-8 (8-pin) or TSSOP-16 (16-pin) variants. Each package has distinct pin counts, functions, and physical dimensions. Interchangeability requires PCB redesign. The MLX90373KVS-ABA-103-SP's DMP-4 footprint is optimized for low-profile, flexible mounting - unlike SOIC-8's through-hole compatibility or TSSOP-16's dual-die redundancy.
