Product details

Overview

MLX90373KVS-ABA-308-SP from Melexis is a Triaxis® Hall-effect position processor IC for absolute linear and angular position sensing using 2-wire PSI5 v2.1 output. It operates from -40°C to +125°C, delivers ±0.85° total angle drift (rotary mode), supports stray-field immunity up to 5 mT, and is AEC-Q100 Grade 0 qualified for automotive pedal and throttle position sensing.

For engineers reviewing the MLX90373KVS-ABA-308-SP datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 package with 4-pin configuration, PSI5 communication timing (500 µs cycle time), programmable 17/32-point piecewise-linear transfer characteristic, and ISO 26262 SEooC ASIL-C functional safety compliance.

Technical Context

The MLX90373KVS-ABA-308-SP implements Triaxis® technology to measure all three magnetic field components (B_X, B_Y, B_Z) on a single die, enabling robust absolute position decoding without external magnets or complex flux concentrators. Its on-chip DSP performs real-time angle calculation, filtering, and diagnostics using configurable FIR filters and programmable transfer functions.

This variant uses the -30x option code, supporting Legacy / Linear & Angular Position modes-not Stray-Field Immune mode-requiring ≥11 mT useful magnetic field norm (B_Norm) and delivering ±0.45° XY total angle drift over temperature. It communicates exclusively via 2-wire PSI5 (v1.3/v2.1) with current modulation, no separate clock line, and built-in watchdogs (IWD/AWD).

Key Specifications

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; not suitable for space-constrained DMP-4 footprints.	Select when functional safety requires dual-channel independence and diagnostic coverage exceeds ASIL-C.
MLX90372KVS-ABA-308-SP	Same DMP-4 package and -308 option code but lacks ISO 26262 SEooC ASIL-C documentation and AEC-Q100 Grade 0 validation.	Acceptable for non-safety-critical industrial linear position sensing; not approved for automotive ECU integration.	Choose only for cost-sensitive non-automotive applications where functional safety certification is unnecessary.

Compared with MLX90371KGO-ABA-300-RE, the MLX90373KVS-ABA-308-SP offers smaller footprint and lower power but no hardware redundancy; versus MLX90372KVS-ABA-308-SP, it adds certified ASIL-C safety evidence and Grade 0 qualification-critical for production automotive use.

FAQ

What is the operating temperature range of the MLX90373KVS-ABA-308-SP?

The MLX90373KVS-ABA-308-SP is rated for continuous operation from -40°C to +125°C ambient temperature. This Grade 0 AEC-Q100 qualification ensures reliable performance in under-hood automotive locations, including near engines and exhaust systems, without thermal derating or additional heatsinking.

Does the MLX90373KVS-ABA-308-SP support both linear and angular position sensing?

Yes, the MLX90373KVS-ABA-308-SP supports both linear and angular position sensing in Legacy / Linear & Angular Position mode (indicated by its -308 option code). It decodes absolute position from magnetic field vector components (B_X, B_Y, B_Z) and outputs calibrated angle or displacement via PSI5, with programmable transfer characteristics for either geometry.

What package type does the MLX90373KVS-ABA-308-SP use, and what are its mounting requirements?

The MLX90373KVS-ABA-308-SP uses the DMP-4 (Dual Mould Package) - a PCB-less, 4-terminal surface-mount package with STD4 trim-and-form straight leads. It requires direct soldering to a host PCB with VSS pins grounded to minimize impedance; unused pin 3 must remain unconnected, and no external decoupling is needed due to integrated regulation.

How does the MLX90373KVS-ABA-308-SP implement functional safety compliance?

The MLX90373KVS-ABA-308-SP is certified as a Safety Element out of Context (SEooC) meeting ISO 26262 ASIL-C requirements. It includes dual watchdogs (IWD/AWD), ECC-protected memory, configurable diagnostics, and documented safety mechanisms - enabling integrators to achieve ASIL-B or ASIL-C system-level compliance without redesigning the sensor subsystem.

What is the minimum magnetic field strength required for accurate operation of the MLX90373KVS-ABA-308-SP?

In Legacy / Linear & Angular Position mode, the MLX90373KVS-ABA-308-SP requires a minimum useful magnetic field norm (B_Norm) of 11 mT for nominal accuracy. Below this threshold, limited performance applies - including increased noise and reduced linearity - as specified in Section 8.2 of the datasheet.
