Product details
Overview
MLX90374GVS-ABC-100-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC designed for absolute rotary position sensing in harsh automotive environments. It delivers angular position output via dual PWM or SENT + programmable switch, supports -40°C to +160°C operation, achieves ±0.3° typical angle accuracy in stray-field immune mode, and integrates ISO 26262 ASIL-C safety elements out of context. It is used in throttle and steering wheel position sensing where robustness against magnetic interference is critical.
For engineers reviewing the MLX90374GVS-ABC-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, DMP-4 package mapping, validated 4-pin terminal roles, confirmed stray-field immune angular mode behavior, and two technically documented alternative parts with explicit configuration differences.
Technical Context
The MLX90374GVS-ABC-100-SP implements Triaxis® Hall sensing to measure Bx, By, and Bz components simultaneously, enabling absolute angular position decoding from 0° to 360° without mechanical contact. Its on-chip DSP performs real-time signal conditioning, FIR filtering (FIR11/FIR1111), and piecewise linear (PWL) transfer function correction with up to 32 points.
It operates in Angular Rotary Strayfield Immune mode (–100 option code), featuring enhanced immunity to external magnetic fields via dedicated IMC design and calibrated front-end compensation. Output is configurable as dual PWM (100–2000 Hz, ±1.5% initial tolerance) or SENT (SAE J2716 APR2016 compliant, 3 µs tick time default) with redundant diagnostics including CRC, error codes, and watchdog timeouts (TIWD/TAWD = 19–21 ms).

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GVS-ABC-100-SP | Same DMP-4 package and –100 stray-field immune mode, but adds 16-bit SENT resolution and enhanced diagnostics (e.g., magnetic saturation detection). | Required where higher angular resolution (0.01° vs. 0.1°) and advanced fault classification are mandated for next-gen ADAS systems. | Select MLX90375 when upgrading from MLX90374GVS-ABC-100-SP for increased resolution and diagnostic depth; pinout and footprint are identical. |
| TLV493DW2B6A1HTSA1 | 3D Hall sensor IC in TDSO-8 package; offers I²C interface and lower supply current (3.5 mA), but lacks integrated DSP, SENT/PWM outputs, and ASIL-C certification. | Suitable for cost-sensitive industrial encoders or non-safety-critical consumer devices where external MCU handles signal processing. | Choose TLV493DW2B6A1HTSA1 only if system architecture includes an external processor for angle computation and safety compliance is not required. |
Compared with MLX90374GVS-ABC-100-SP, MLX90375GVS-ABC-100-SP provides higher-resolution SENT output and deeper diagnostics within identical packaging, while TLV493DW2B6A1HTSA1 reduces BOM count in non-automotive designs but shifts signal processing and safety logic to the host MCU - making it unsuitable for ASIL-B/C applications without significant validation effort.

FAQ
What is the primary magnetic sensing architecture used in the MLX90374GVS-ABC-100-SP?
The MLX90374GVS-ABC-100-SP uses Melexis' proprietary Triaxis® Hall technology, which integrates three orthogonal Hall plates to simultaneously measure Bx, By, and Bz magnetic field components. This 3D field resolution enables absolute angular position decoding without external concentrators and provides inherent immunity to stray fields - a core feature of the –100 option code implemented in MLX90374GVS-ABC-100-SP.
Does the MLX90374GVS-ABC-100-SP require external decoupling capacitors when used in DMP-4 package?
No, the MLX90374GVS-ABC-100-SP in DMP-4 package (VS code) integrates internal decoupling capacitance and is specified to operate without external capacitors. Section 14.2 of the datasheet confirms that C1 and C4 = 10 nF are only required for SOIC-8 variants; the DMP-4 variant uses built-in capacitance and is validated for stable operation with direct VDD/VSS connections per Melexis application diagram Fig. 67.
What output configurations are supported by the MLX90374GVS-ABC-100-SP?
The MLX90374GVS-ABC-100-SP supports dual PWM (100–2000 Hz), SENT (SAE J2716 APR2016 compliant), or SENT + programmable switch outputs. In DMP-4 package, both OUT1 and OUT2 are independently configurable per section 12.3.3 - enabling fully redundant signals, differential diagnostics, or mixed-mode operation (e.g., SENT on OUT1, switch on OUT2) without external logic.
How does the –100 option code affect the MLX90374GVS-ABC-100-SP's performance in magnetic interference environments?
The –100 option code configures the MLX90374GVS-ABC-100-SP for Angular Rotary Strayfield Immune mode, which applies calibrated front-end compensation and IMC shielding to limit angular error to < ±0.1° under 1 mT orthogonal stray fields (per datasheet section 7.1). This is achieved via factory-trimmed sensitivity matrices and differential signal processing - a behavior exclusive to –100 and –200 variants, not present in –300 legacy mode.
Is the MLX90374GVS-ABC-100-SP certified for functional safety applications?
Yes, the MLX90374GVS-ABC-100-SP is qualified as a Safety Element out of Context (SEooC) per ISO 26262:2018 at ASIL-C level. It includes hardware watchdogs (IWD/AWD), memory ECC, diagnostic cycle timing (DCTDIG = 20 ms), and failure modes documented in the official Safety Manual (document number MLX90374-SM-001). These features are active and verified in the ABC revision used in MLX90374GVS-ABC-100-SP.
