Product details
Overview
MLX90373KVS-ABA-108-SP from Melexis is a Triaxis® position processor IC for absolute rotary position sensing with stray-field immunity up to 5 mT, PSI5 v1.3/v2.1 interface, AEC-Q100 Grade 0 qualification, and operation from −40°C to +125°C in DMP-4 package. It delivers 12-bit angular output with ≤0.85° total angle drift and supports programmable piecewise-linear transfer characteristics.
For engineers reviewing the MLX90373KVS-ABA-108-SP datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immune angular accuracy, PSI5 timing compliance (300–500 µs cycle), DMP-4 mechanical form factor, and end-user programmability of transfer characteristic and diagnostics.
Technical Context
The MLX90373KVS-ABA-108-SP implements Triaxis® Hall technology to measure all three magnetic field components (BX, BY, BZ) and compute absolute angle via on-chip DSP. Its -108 option code specifies Rotary Stray-Field Immune mode with 4-pole magnet support and useful signal defined as ∆BXY/∆XY ≥ 4.1 mT/mm.
It uses a 2-wire PSI5 interface over supply lines with configurable cycle time (300–500 µs), latency ≤850 µs (no filtering), and step response ≤2125 µs. Internal regulation provides VDEC = 3.3 V ±0.1 V and digital supply VDDD = 1.85 V ±0.05 V, with undervoltage detection thresholds at 3.70–4.10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DMP-4 is a dual-mold, PCB-less surface-mount package with 4 terminals and straight leads (STD4 2.54 mm pitch per ordering code "-108"). It enables compact, cost-effective integration into space-constrained sensor assemblies without PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains - must be connected to system ground for EMC compliance |
| 2 | VDD | Supply input and PSI5 data output line - carries bidirectional current-modulated PSI5 frames |
| 3 | N.C. | No internal connection - electrically isolated; recommended to tie to ground for shielding |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground impedance in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous BX, BY, BZ measurement enables true 3D magnetic field decoding for absolute angle without mechanical stops |
| Stray-Field Immune Mode | Uses magnetic gradient (∆BXY/∆XY) instead of absolute field magnitude - rejects uniform external fields up to 5 mT |
| Programmable Transfer Characteristic | Supports 4-/8-point linear or 17-/32-point piecewise-linear calibration - adapts to non-ideal magnet geometry and mechanical tolerances |
| PSI5 v1.3/v2.1 Compliance | Includes synchronization pulse, CRC protection, and configurable frame structure - interoperable with standard automotive sensor hubs |
| AEC-Q100 Grade 0 | Qualified for 125°C ambient operation with HTOL and ESD testing - suitable for engine bay and transmission applications |
| End-User Programmability | Allows field calibration of transfer curve, filter settings, and diagnostics via PTC - eliminates factory trim dependency |

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-100-RE | TSSOP-16 dual-die redundant architecture; higher quiescent current (2×10–13.5 mA); isolation resistance >4 MΩ between dice | Targeted at ASIL-D systems requiring hardware redundancy; larger footprint and higher cost | Select when functional safety requirements exceed ASIL-C or fault tolerance mandates die-level redundancy |
| MLX90372KVS-ABA-100-SP | DMP-4 package like MLX90373KVS-ABA-108-SP but with legacy (-100) rather than stray-field immune (-108) magnetic mode; lower stray-field immunity (no ∆BXY/∆XY processing) | Suitable for shielded environments where external field interference is controlled; reduced magnetic design complexity | Select when magnetic circuit provides inherent stray-field suppression and cost optimization is prioritized over field immunity headroom |
Compared with MLX90373KVS-ABA-108-SP, MLX90371KGO-ABA-100-RE adds hardware redundancy at the expense of size and power, while MLX90372KVS-ABA-100-SP retains the same DMP-4 form factor but omits stray-field immune signal processing - making it less suitable for unshielded high-EMI locations.

FAQ
What is the magnetic operating mode of MLX90373KVS-ABA-108-SP?
The MLX90373KVS-ABA-108-SP operates in Rotary Stray-Field Immune mode, identified by the "-108" option code. It computes angle from the magnetic field gradient (∆BXY/∆XY) rather than absolute field strength, enabling immunity to uniform stray fields up to 5 mT as verified per ISO 11452-8. This mode requires a 4-pole magnet and supports up to 180° mechanical range.
Does MLX90373KVS-ABA-108-SP require an external microcontroller for calibration?
No, MLX90373KVS-ABA-108-SP supports end-user programmability via Programming Through Connector (PTC), allowing full calibration-including multi-point transfer characteristic, filter coefficients, and diagnostic thresholds-to be performed in-system without external MCU intervention. The device stores calibrated parameters in NVRAM with ECC protection.
What is the PSI5 timing compliance of MLX90373KVS-ABA-108-SP?
The MLX90373KVS-ABA-108-SP complies with PSI5 v1.3 and v2.1 specifications, supporting cycle times from 300 µs to 500 µs, bit times of 5–8.4 µs, and sync pulse hold times ≥9 µs. Its default latency is ≤850 µs with no filtering enabled, and worst-case step response is ≤2125 µs in rotary mode-meeting real-time control requirements for automotive ECUs.
Can MLX90373KVS-ABA-108-SP be used in linear position sensing applications?
Yes, MLX90373KVS-ABA-108-SP can be configured for linear position sensing via appropriate magnet arrangement and end-user programming of the transfer characteristic. However, its -108 option code is optimized for rotary stray-field immune use; for dedicated linear applications, Melexis recommends -30x option codes (e.g., ABA-308) which use BNORM instead of gradient-based computation.
What package type does MLX90373KVS-ABA-108-SP use and how is it mounted?
MLX90373KVS-ABA-108-SP uses the DMP-4 (Dual Mould Package) - a PCB-less, surface-mount package with four terminals and STD4 2.54 mm pitch straight leads. It is soldered directly onto the host board using reflow, with terminals 1 and 4 serving as ground and terminal 2 as combined VDD/PSI5 data line; terminal 3 is not connected and should be grounded for EMC.
