Product details
Overview
MLX90373KGO-ABA-300-SP 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, AEC-Q100 Grade 0 qualification, and stray-field immunity up to 5 mT - deployed in automotive throttle, pedal, and ride height sensors.
For engineers reviewing the MLX90373KGO-ABA-300-SP datasheet, pinout, applications, or equivalent options, key selection criteria include TSSOP-16 dual-die redundancy, PSI5 v1.3/v2.1 compliance, programmable piecewise-linear transfer characteristic (up to 32 points), ISO 26262 SEooC ASIL-C readiness, and magnetic field gradient sensitivity of 0.075–0.125 mT/mm.
Technical Context
The MLX90373KGO-ABA-300-SP implements Triaxis® Hall sensing with integrated IMC (Integrated Magnetic Concentrator) to resolve BX, BY, and BZ flux components, enabling robust absolute position decoding from rotating or linearly moving magnets. Its dual-die TSSOP-16 package provides full hardware redundancy for safety-critical systems.
It uses on-chip DSP to compute angle/position from raw magnetic data, supports configurable filtering (Filter = 0–2), and delivers output via 2-wire PSI5 current modulation with cycle times of 300–500 µs. The -300 option code configures it for legacy/linear-angular mode with BNorm ≥11 mT nominal useful field strength.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +125°C - qualified for under-hood automotive environments without derating. |
| PSI5 Interface | v1.3 & v2.1 compliant - enables deterministic 2-wire communication over supply line with 300–500 µs cycle time. |
| Angle Accuracy | ±0.85° total drift (XY mode) - specifies maximum deviation after calibration across temperature and lifetime. |
| Magnetic Sensitivity | 0.075–0.125 mT/mm resolution - defines smallest detectable field gradient change for position calculation. |
| Supply Voltage | 4.1–6 V - compatible with standard 5 V automotive sensor rails; includes undervoltage lockout at 3.7–4.1 V. |
| Quiescent Current | 9–12.5 mA - dual-die current draw in legacy mode, enabling low-power ECU integration. |
| Safety Certification | ISO 26262 SEooC ASIL-C - provides documented safety mechanisms for use in ASIL-B/C system architectures. |
Pinout & Package
TSSOP-16 package (GO code) houses two fully redundant dies for functional safety compliance; requires PCB-level grounding of all unused pins per EMC guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - must be connected to local 100 nF ceramic capacitors for stable analog reference. |
| 2, 10 | VSS1 / VSS2 | Independent ground terminals per die - isolation resistance >4 MΩ between dice ensures fault separation. |
| 3, 11 | VDD1 / VDD2 | Separate supply inputs per die - enables independent power domain monitoring and fault detection. |
| 4, 12 | IN1 / IN2 | External sensor input - internally grounded in application; unused in standard Triaxis® configurations. |
| 5, 13 | TEST2 / TEST1 | Test pins - internally grounded; connect to PCB ground for optimal EMC performance. |
| 6, 15 | IDATA2 / IDATA1 | Current sensing outputs - must remain unconnected per datasheet; not used in PSI5 operation. |
| 7, 8, 14, 16 | N.C. | No-connect pins - require PCB ground connection to suppress parasitic coupling and meet EMC requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Hall Sensing | Simultaneous BX/BY/BZ measurement enables true 3D magnetic field reconstruction for stray-field immune angle decoding. |

| Dual-Die Redundancy (TSSOP-16) | Hardware-isolated signal chains support cross-checking and fault detection required for ASIL-C system integration. |
| Stray-Field Immunity | Validated to ISO 11452-8:2015 - maintains <0.6° error under 4 kA/m external fields, critical for EV powertrain proximity. |
| End-User Programmable Diagnostics | Configurable watchdog timeouts, field threshold monitors, and filter settings enable application-specific safety response tuning. |

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-SP | Single-die TSSOP-16; no inter-die isolation; lacks ASIL-C SEooC documentation. | Lower-cost alternative for ASIL-B systems where dual-die redundancy is not mandated. | Select when functional safety requirements stop at ASIL-B and cost optimization is prioritized over fault containment. |
| MLX90374KGO-ABA-300-SP | Enhanced 14-bit resolution; extended PSI5 frame capacity; updated diagnostic register set. | Required for next-gen ADAS platforms needing higher angular fidelity and expanded diagnostic coverage. | Choose when migrating from MLX90373KGO-ABA-300-SP to meet tighter accuracy specs (<±0.3° drift) or new OEM diagnostic mandates. |
Compared with MLX90373KGO-ABA-300-SP, MLX90371KGO-ABA-300-SP reduces BOM cost by eliminating die redundancy but forfeits ASIL-C capability, while MLX90374KGO-ABA-300-SP adds resolution and diagnostic depth at higher unit cost and firmware integration effort.

FAQ
What is the primary sensing architecture used in the MLX90373KGO-ABA-300-SP?
The MLX90373KGO-ABA-300-SP employs Triaxis® Hall technology with an integrated magnetic concentrator (IMC) to simultaneously measure the X, Y, and Z components of magnetic flux density. This enables robust absolute angle or linear position decoding from magnet motion, independent of magnet orientation or air gap variation - a capability confirmed in the Revision 2.0 datasheet section 1 and Figure 1 block diagram.
Does the MLX90373KGO-ABA-300-SP support both angular and linear position sensing?
Yes, the MLX90373KGO-ABA-300-SP is configured for linear/angular position sensing via its -300 option code, supporting legacy magnetic configurations (rotary or linear) with BNorm ≥11 mT nominal useful field strength. Its programmable transfer characteristic (up to 32-point PWL) adapts to either geometry, as specified in Table 12 and section 13.1 of the datasheet.
What safety certifications apply to the MLX90373KGO-ABA-300-SP?
The MLX90373KGO-ABA-300-SP is AEC-Q100 Grade 0 qualified and certified as a Safety Element out of Context (SEooC) meeting ISO 26262 ASIL-C requirements. Its TSSOP-16 dual-die architecture, internal watchdogs (IWD/AWD), and diagnostic registers provide the foundation for system-level ASIL-B/C implementation - details are in sections 14.1–14.2 of the datasheet.
What is the recommended supply voltage range for reliable operation of the MLX90373KGO-ABA-300-SP?
The MLX90373KGO-ABA-300-SP operates reliably within 4.1 V to 6.0 V for PSI5 communication, with undervoltage lockout thresholds at 3.70–4.00 V (low) and 3.80–4.10 V (high). Exceeding 6 V risks damage, as defined in Table 8's "Operating Supply Voltage" row and Absolute Maximum Ratings section.
How does the MLX90373KGO-ABA-300-SP achieve stray magnetic field immunity?
The MLX90373KGO-ABA-300-SP achieves stray-field immunity through Triaxis® differential sensing and proprietary signal processing that rejects common-mode field components. It maintains <0.6° error under 4 kA/m (5 mT) stray fields per ISO 11452-8:2015 testing - a specification explicitly validated for the -300 configuration in section 9.1.1.3 and Table 11 footnote 17.
