Product details
Overview
MLX90374GDC-ABB-300-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers dual-output signals (PWM or SENT + programmable switch), supports AEC-Q100 Grade 0 qualification (−40°C to +160°C), achieves ±0.3° angular accuracy in legacy mode, and integrates on-chip DSP for stray-field-immune operation in automotive throttle and steering wheel position systems.
For engineers reviewing the MLX90374GDC-ABB-300-RE datasheet, pinout, applications, or equivalent options, key selection considerations include SOIC-8 package compatibility, dual-output configurability (PWM/SENT), ISO 26262 ASIL-C safety element out of context compliance, and −40°C to +160°C operating range with stray-field robustness for under-hood automotive use.
Technical Context
The MLX90374GDC-ABB-300-RE implements Triaxis® Hall sensing to measure Bx, By, and Bz magnetic field components simultaneously, enabling absolute angle decoding from 0° to 360° or linear displacement without mechanical contact. Its integrated DSP performs real-time signal conditioning, FIR filtering (FIR11/FIR1111), and programmable piecewise-linear (PWL) transfer characteristic mapping (up to 32 points).
This variant uses the ABB chip revision in SOIC-8 (DC) package and operates in Legacy/Standard mode (−300 option code), supporting both continuous asynchronous acquisition (528–588 µs measurement period) and SENT synchronous timing (e.g., 3 µs tick, 320-tick frame). It features dual independent outputs-OUT1 and OUT2-with configurable PWM frequency (100–2000 Hz) or SENT SAE J2716 APR2016 compliance including error codes and user-defined data fields.

| 3 - OUT2 | Secondary digital output | Configurable as PWM, SENT, or programmable switch; supports redundancy or dual-signal reporting |
| 4 - Test | Test/programming interface | Internally grounded in application; tie to PCB ground to minimize noise coupling |
| 5 - OUT1 | Primary digital output | Default SENT or PWM output; synchronized with OUT2 in redundant configurations |
| 6 - VSS | Digital ground reference | Must be connected to low-impedance digital ground plane; separate from analog ground if possible |
| 7 - VDEC | Analog voltage decoupling | Requires 100 nF ceramic capacitor to ground; stabilizes internal 3.3 V analog supply rail |
| 8 - VSS | Analog ground reference | Dedicated analog ground pin; isolate from digital return paths to preserve ADC SNR |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90374GDC-ABC-300-RE | ABC revision replaces ABB; adds enhanced diagnostics, safe startup sequence, and improved ESD robustness | Same SOIC-8 package and −300 legacy mode, but supports full ASIL-C diagnostic coverage per safety manual | Select ABC-300 for new designs requiring updated safety mechanisms and long-term lifecycle support |
| MLX90363GSE-AAA-000-SP | Single-output SENT-only device; no PWM or switch function; lower accuracy (±0.5°); no programmable PWL | Targeted at cost-sensitive, single-signal applications like basic throttle position where redundancy is not required | Choose MLX90363 when only one SENT output is needed and advanced calibration or dual outputs are unnecessary |

FAQ
What is the operating temperature range of the MLX90374GDC-ABB-300-RE?
The MLX90374GDC-ABB-300-RE is rated for operation from −40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood automotive placement without external thermal management, and its performance specifications-including angular accuracy and startup time-are guaranteed across this full interval per the official datasheet revision 4.
Does the MLX90374GDC-ABB-300-RE support SENT and PWM simultaneously?
No-the MLX90374GDC-ABB-300-RE supports either dual PWM outputs or a SENT + programmable switch configuration, but not SENT and PWM concurrently on the same device. OUT1 and OUT2 can be independently assigned to PWM, SENT, or switch functions per configuration settings stored in NVRAM, as defined in section 12.3 of the datasheet.
What package type does the MLX90374GDC-ABB-300-RE use?
The MLX90374GDC-ABB-300-RE uses the SOIC-8 package (designated by "DC" in the part number), with dimensions of 5.3 mm × 6.2 mm and 1.27 mm lead pitch. It is RoHS-compliant, qualified for automotive reflow profiles, and features dedicated analog and digital ground pins (VSS) to minimize noise coupling in precision position applications.
Is the MLX90374GDC-ABB-300-RE ISO 26262 certified?
The MLX90374GDC-ABB-300-RE is qualified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC), meaning it provides documented safety mechanisms-including watchdog timers, memory ECC, and diagnostic cycles-but requires integration-level verification by the end-system manufacturer to achieve full ASIL-B or ASIL-C compliance in final applications.
What is the angular accuracy specification for the MLX90374GDC-ABB-300-RE?
In Legacy/Standard mode (−300 option code), the MLX90374GDC-ABB-300-RE achieves ±0.3° typical angular accuracy over temperature and lifetime, as specified in section 8.4 of the datasheet. This accuracy applies to absolute rotary position sensing with appropriate magnet geometry and calibration, and includes contributions from INL, thermal drift, and signal processing residuals.
