Product details
Overview
MLX90373KVS-ABA-308-RE from Melexis is a Triaxis® position processor IC for absolute linear and angular position sensing using 3-axis Hall technology, delivering 12-bit PSI5 output with ±0.85° total angle drift over −40°C to +125°C, stray-field immunity up to 5 mT, and AEC-Q100 Grade 0 qualification - deployed in automotive throttle and pedal position systems.
For engineers reviewing the MLX90373KVS-ABA-308-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (DMP-4), confirmed PSI5 v1.3/v2.1 timing (500 µs cycle time), calibrated transfer characteristics (up to 32-point PWL), functional safety compliance (ISO 26262 SEooC ASIL-C), and real-world magnetic field specifications (≥11 mT useful BNorm).
Technical Context
The MLX90373KVS-ABA-308-RE implements Triaxis® Hall sensing with on-chip DSP for absolute position decoding from BX, BY, and BZ flux components. Its dual-mold DMP-4 package supports PCB-less mounting and integrates regulated 3.3 V analog supply (VDEC) with ±150 mV UV/OV hysteresis.
This variant operates in Standard/Legacy mode (−30x option code), supporting x-y, x-z, and y-z sensing configurations with IMC gain compensation (GIMC = 1.19), 12-bit resolution, and programmable filtering (FIR/EMA). It uses 2-wire PSI5 communication at 500 µs cycle time with 8.4 µs bit time and 2125 µs worst-case step response.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.1–6 V - compatible with standard 5 V automotive sensor rails; no external regulator needed |
| PSI5 Cycle Time | 500 µs - enables 2 kHz position update rate for real-time control loops |
| Angle Accuracy | ±0.85° total drift - calibrated performance across −40°C to +125°C, referenced to 35°C |
| Magnetic Sensitivity | ≥11 mT BNorm - minimum usable field strength for nominal accuracy in legacy mode |
| Stray-Field Immunity | Up to 5 mT (4 kA/m) - validated per ISO 11452-8, enabling operation near high-current wiring |
| Functional Safety | ISO 26262 SEooC ASIL-C - includes AWD/IWD watchdogs, CRC-protected frames, and ECC memory |
| Operating Temp | −40°C to +125°C - qualified per AEC-Q100 Grade 0 for under-hood automotive use |
Pinout & Package
DMP-4 is a dual-mold, PCB-less surface-mount package with 4 terminals: two ground pins (VSS), one supply/PSI5-output pin (VDD), and one not-connected pin (N.C.). Designed for direct soldering onto flex or rigid boards without carrier PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground return path - must be connected to system ground for EMC and bias stability |
| 2 | VDD | Supply input and PSI5 data output - carries both power and modulated current signal (2-wire) |
| 3 | N.C. | No internal connection - leave unconnected; avoid routing traces to prevent parasitic coupling |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground impedance |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Hall Sensing | Simultaneous BX/BY/BZ measurement enables robust absolute position decoding without mechanical cam or gear constraints |
| Programmable Transfer Characteristic | Configurable 4-, 8-, or 32-point piecewise-linear (PWL) curve - eliminates need for external lookup tables or host-side calibration |
| PSI5 v1.3 & v2.1 Compliance | 2-wire interface with CRC, synchronization pulse, and error reporting - interoperable with standard automotive ECU PSI5 receivers |
| Stray-Field Immune Operation | Validated 180° angle sensing under 4 kA/m stray fields - critical for EV powertrain and ADAS proximity applications |
| End-of-Line Programmability | PTC-enabled configuration via connector - allows final trim of offset, sensitivity, and diagnostics without reflow |

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 (21 mA); isolated dice (4 MΩ inter-die resistance) | Required for ASIL-D systems needing full hardware redundancy; larger footprint and higher cost | Select when dual-die fault containment and inter-die isolation are mandated by safety architecture |
| MLX90372KVS-ABA-308-RE | DMP-4 package same as MLX90373KVS-ABA-308-RE but lacks ISO 26262 SEooC ASIL-C certification and advanced diagnostics | Suitable for non-safety-critical industrial position sensing; no AWD/IWD or CRC frame validation | Choose for cost-sensitive applications where functional safety certification is not required |
Compared with MLX90373KVS-ABA-308-RE, the MLX90371KGO-ABA-300-RE provides hardware-level redundancy at the expense of size and power, while the MLX90372KVS-ABA-308-RE offers identical form factor and basic functionality without safety certification - making MLX90373KVS-ABA-308-RE the optimal balance of compactness, stray-field resilience, and ASIL-C readiness.

FAQ
What is the primary sensing mode supported by MLX90373KVS-ABA-308-RE?
The MLX90373KVS-ABA-308-RE operates in Standard/Legacy mode (indicated by "308" option code), supporting x-y, x-z, and y-z magnetic field configurations with IMC gain compensation. It delivers absolute linear or angular position output using 12-bit PSI5 frames, optimized for applications like throttle and pedal sensors where full 360° rotation or multi-axis field geometry is used.
Does MLX90373KVS-ABA-308-RE require an external decoupling capacitor?
No - the MLX90373KVS-ABA-308-RE integrates an internal regulated 3.3 V analog supply (VDEC) with built-in decoupling. The DMP-4 package has no dedicated VDEC pin; instead, local 100 nF ceramic capacitance between VDD and VSS on the target PCB is recommended per Melexis layout guidelines to suppress PSI5-induced ripple and ensure stable startup.
How is stray-field immunity validated for MLX90373KVS-ABA-308-RE?
MLX90373KVS-ABA-308-RE is tested per ISO 11452-8:2015 at 30°C with 4 kA/m (5 mT) stray fields applied from any direction. Under these conditions, its output angle error remains ≤0.6° - a specification confirmed in the datasheet's accuracy table for "Output Stray Field Immunity (∂θFF)" and applicable to all legacy-mode configurations.
Can MLX90373KVS-ABA-308-RE be programmed after soldering to the PCB?
Yes - MLX90373KVS-ABA-308-RE supports Programming Through Connector (PTC) via its VDD pin using Melexis' PTC protocol. This allows end-of-line trimming of offset, sensitivity, transfer characteristic, and diagnostics without requiring reflow or special test fixtures, enabling final calibration after mechanical assembly and environmental stress.
What is the maximum PSI5 data rate achievable with MLX90373KVS-ABA-308-RE?
The MLX90373KVS-ABA-308-RE supports a minimum PSI5 cycle time of 300 µs (3.33 kHz frame rate) and typical 500 µs (2 kHz), per Table 10 in the datasheet. At 500 µs, it delivers full 12-bit position data plus CRC and status bits per frame. Higher rates require confirming thermal limits and ECU receiver compatibility, as maximum voltage (18 V) and die temperature constrain sustained operation.
