Product details
Overview
MLX90374GDC-ABC-100-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute angular rotary sensing in stray-field-immune configurations. It delivers dual PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and is AEC-Q100 qualified for automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90374GDC-ABC-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed pin functions, exact output timing (100–2000 Hz PWM), stray-field immunity specification (-100 code), and validated alternatives for angular position sensing in harsh environments.
Technical Context
The MLX90374GDC-ABC-100-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling precise 0–360° absolute angle decoding with on-chip DSP and analog signal conditioning. Its architecture supports programmable linear transfer characteristics using 4- or 8-point piecewise linear (PWL) calibration.
This variant uses the ABC chip revision in SOIC-8 (DC) package with -100 option code - specifically configured for angular rotary stray-field-immune operation. It implements dual PWM output with configurable redundancy modes and includes integrated diagnostics such as intelligent watchdog (20 ms timeout) and fail-safe state duration (9.8–34.6 ms).

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90375GDC-ABC-100-SP | Same SOIC-8 package and -100 stray-field immunity, but adds SENT+PWM dual-output mode (vs. PWM-only in MLX90374) | Required where host ECU mandates SAE J2716 SENT protocol alongside PWM redundancy | Select MLX90375 if SENT communication is needed; otherwise MLX90374 suffices for pure PWM architectures. |
| AMS AS5055A-BQFT | 12-bit SPI output only; no dual-output capability or ASIL-C certification; ±0.5° typical INL | Suitable for non-safety-critical industrial rotary encoders, not automotive ASIL-B/C systems | Use only in cost-sensitive, non-automotive applications lacking functional safety requirements. |
Compared with MLX90374GDC-ABC-100-SP, MLX90375 offers protocol flexibility at higher BOM cost, while AMS AS5055A lacks automotive qualification and redundancy - making MLX90374 the optimal balance of safety, robustness, and dual-PWM simplicity for ASIL-C throttle and steering systems.

FAQ
What is the operating temperature range of the MLX90374GDC-ABC-100-SP?
The MLX90374GDC-ABC-100-SP is rated for continuous operation from -40°C to +160°C ambient temperature, meeting AEC-Q100 Grade 0 requirements. This range is validated for under-hood automotive use, including proximity to engines and power electronics, and is supported by thermal performance data in section 17.10 of the datasheet.
Does the MLX90374GDC-ABC-100-SP support SENT output?
No, the MLX90374GDC-ABC-100-SP is configured exclusively for dual PWM output per its -100 option code and SOIC-8 (DC) package. SENT capability is available only in variants with option codes ending in -300 or -107 and requires DMP-4 packaging or specific configuration - not implemented in this part number.
What does the "-100" in MLX90374GDC-ABC-100-SP signify?
The "-100" suffix denotes the magnetic configuration: Angular Rotary Strayfield Immune mode. This setting optimizes the MLX90374GDC-ABC-100-SP's internal DSP and front-end for 0–360° absolute angle measurement with guaranteed accuracy under ±1 T external magnetic interference - essential for EV drivetrain and braking systems.
Is the MLX90374GDC-ABC-100-SP pin-compatible with earlier ABB revisions?
No - while physically identical in SOIC-8 packaging, the MLX90374GDC-ABC-100-SP uses the ABC chip revision which includes enhanced diagnostics, safe startup sequencing, and updated stray-field immunity algorithms not present in ABB. Migration requires firmware and calibration validation per Melexis Application Note AN-102.
How is functional safety implemented in the MLX90374GDC-ABC-100-SP?
The MLX90374GDC-ABC-100-SP achieves ISO26262 ASIL-C as a Safety Element out of Context via integrated mechanisms: dual PWM channel comparison, intelligent watchdog (20 ms timeout), analog/digital diagnostic cycles (34 ms and 20 ms), and fail-safe state activation within 11.9 ms after fault detection - all documented in section 13 of the datasheet.
