Product details
Overview
MLX90372GDC-ACE-200-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing in stray-field-immune configurations. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO26262 ASIL-C safety compliance, and supports programmable piecewise-linear transfer characteristics up to 32 points. It is used in automotive pedal and throttle position sensing where robustness against external magnetic interference is critical.
For engineers reviewing the MLX90372GDC-ACE-200-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOIC-8), confirmed linear stray-field-immune operation mode, SENT/PWM dual-output capability, AEC-Q100 qualification, and functional safety architecture details required for automotive sensor design and validation.
Technical Context
The MLX90372GDC-ACE-200-RE implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling high-accuracy absolute linear position decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, angle calculation, and SENT frame encoding with CRC and error codes.
This variant is factory-configured for Linear Stray-field Immune Mode (-200 option code), uses SOIC-8 packaging (DC), and supports SENT 3µs timing mode with built-in diagnostics including intelligent watchdog (20 ms timeout) and analog/digital diagnostic cycle times of 34 µs and 20 ms respectively.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GDC-ABF-200-RE | Lacks ISO26262 ASIL-C certification; single-die architecture; no SENT protocol support - PWM-only output | Targeted at cost-sensitive industrial linear sensing, not safety-critical automotive functions | Select only if ASIL-C compliance and SENT diagnostics are not required |
| TLV493DW2B6HTSA1 | 3D Hall sensor with I²C interface; no on-chip DSP or programmable transfer curve; ±2.5 mT field range vs. ±1 T for MLX90372 | Suitable for low-precision proximity or tilt detection, not high-accuracy linear position with stray-field immunity | Choose when compact size and I²C integration outweigh need for automotive-grade accuracy and robustness |
