Product details
Overview
MLX90373KVS-ABA-108-RE from Melexis is a Triaxis® Hall-based absolute rotary position sensor IC for stray-field immune angular sensing in automotive applications. It delivers 12-bit PSI5 output, supports ±0.85° total angle drift over −40°C to +125°C, and operates with 6–18 V supply in DMP-4 package. Used in throttle and steering wheel position sensing where magnetic robustness is critical.
For engineers reviewing the MLX90373KVS-ABA-108-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, PSI5 timing constraints, stray-field immunity validation (ISO 11452-8), angular accuracy specs, and DMP-4 terminal mapping - all confirmed for the -108 option code and K-temp grade.
Technical Context
The MLX90373KVS-ABA-108-RE implements Triaxis® technology to measure all three magnetic field components (BX, BY, BZ), enabling stray-field immune angular decoding up to 180° using in-plane gradient ∆BXY/∆XY as the primary signal. Its on-chip DSP performs real-time piecewise-linear transfer function correction with up to 32 points, configurable via end-user programming.
It uses 2-wire PSI5 v1.3/v2.1 communication over supply lines with 300–500 µs cycle time, 850 µs latency, and 1480–2125 µs worst-case step response. The device integrates dual watchdogs (IWD/AWD), diagnostics (analog/digital), and meets ISO 26262 SEooC ASIL-C requirements for safety-critical systems.

FAQ
What is the PSI5 communication protocol supported by the MLX90373KVS-ABA-108-RE?
The MLX90373KVS-ABA-108-RE supports PSI5 v1.3 and v2.1 over its 2-wire interface, with cycle times of 300–500 µs, 8.4 µs max bit time, and synchronous pulse hold time ≥9 µs. It transmits 12-bit angular data with CRC and diagnostic flags, fully compliant with automotive ECU receiver requirements. The MLX90373KVS-ABA-108-RE does not support SENT or PWM output modes.
How does the MLX90373KVS-ABA-108-RE achieve stray-field immunity up to 4 kA/m?
The MLX90373KVS-ABA-108-RE achieves stray-field immunity by measuring the spatial gradient ∆BXY/∆XY rather than absolute field magnitude, allowing rejection of uniform external fields while preserving sensitivity to local magnet motion. Validated per ISO 11452-8, it maintains ≤0.6° angular error at 4 kA/m. This capability is intrinsic to the -108 option code's rotary stray-field immune mode and requires no external shielding. The MLX90373KVS-ABA-108-RE's Triaxis® architecture enables this behavior without additional components.
What is the angular accuracy specification for MLX90373KVS-ABA-108-RE over temperature?
The MLX90373KVS-ABA-108-RE specifies ±0.85° total angle drift over −40°C to +125°C after calibration, relative to 35°C reference. This includes contributions from temperature coefficient, aging, and magnetic hysteresis. Intrinsic linearity error is ±1° before calibration, reducible via end-user 32-point PWL programming. Noise is 0.2–0.7° pk-pk depending on filter setting. The MLX90373KVS-ABA-108-RE meets these values under nominal magnetic conditions (≥4.1 mT/mm useful gradient).
Can the MLX90373KVS-ABA-108-RE be used for linear position sensing?
No - the MLX90373KVS-ABA-108-RE is configured exclusively for angular rotary stray-field immune operation (option code -108). Linear position sensing requires -30x option codes (e.g., ABA-300), which implement different magnetic front-end configurations and transfer functions. Attempting linear use with MLX90373KVS-ABA-108-RE will result in invalid output due to mismatched gradient interpretation and calibration tables. The MLX90373KVS-ABA-108-RE's firmware and factory trim are fixed to rotary mode.
What package type and pin configuration does MLX90373KVS-ABA-108-RE use?
The MLX90373KVS-ABA-108-RE uses the DMP-4 (Dual Mold Package) - a PCB-less, 4-terminal surface-mount package measuring 5.0 × 4.0 mm. Pins are: 1=VSS, 2=VDD/PSI5-OUT, 3=N.C., 4=VSS. Pin 3 must be tied to ground for EMC; both VSS pins serve as low-impedance return paths. This package eliminates PCB interposer layers, reducing height and thermal resistance. The MLX90373KVS-ABA-108-RE is not available in SOIC-8 or TSSOP-16 variants.
