Product details
Overview
MLX90372GDC-ACC-200-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC in SOIC-8 package, delivering absolute linear position sensing with stray-field immunity, SENT or PWM output, and AEC-Q100 qualification for automotive pedal and throttle applications.
For engineers reviewing the MLX90372GDC-ACC-200-SP datasheet, pinout, applications, or equivalent options, key selection criteria include linear stray-field immune operation (–200 option code), SOIC-8 footprint compatibility, SENT 3µs timing compliance, ISO26262 ASIL-C safety element out of context support, and programmable piecewise linear transfer characteristic up to 32 points.
Technical Context
The MLX90372GDC-ACC-200-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute linear position decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning and angle calculation using factory-configured or user-programmed PWL transfer functions.
This variant uses the ACC chip revision and –200 option code, specifying linear position mode with enhanced stray-field immunity, SENT 3µs output timing, and SOIC-8 packaging. It operates across –40°C to +160°C with supply voltage range 4.5–5.5 V (regulated) or 6–18 V (battery), and supports diagnostic cycle times of 34 ms in asynchronous acquisition mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic linear position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GDC-ACE-200-RE | ACE revision replaces ACC; improved startup time (11.2 ms vs 12.4 ms), updated EEPROM reliability, and extended lifecycle support | Same linear stray-field immune functionality, SOIC-8 package, and SENT 3µs timing - direct drop-in replacement for new designs | Select ACE-200 for new designs; ACC-200 remains in production but not recommended for new projects per Melexis documentation |
| MLX90371GDC-ACC-200-RE | Legacy Triaxis® device with fixed 8-point PWL, no SENT protocol support, PWM-only output, and no ASIL-C safety documentation | Limited to basic linear position feedback where diagnostics and secure serial communication are not required | Only consider if legacy system compatibility or cost sensitivity outweighs need for SENT, safety certification, or advanced programmability |
Compared with MLX90372GDC-ACC-200-SP, the ACE-200 offers faster safe startup and longer-term supply assurance, while the MLX90371GDC-ACC-200-RE lacks SENT, ASIL-C, and flexible PWL - making it unsuitable for modern automotive safety-critical linear sensing.
