Product details
Overview
MLX90372GGO-ACC-200-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute linear position sensing with stray-field immunity. It delivers SENT or PWM output, operates from -40°C to +160°C, features ISO 26262 ASIL-C safety compliance, and is AEC-Q100 qualified for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90372GGO-ACC-200-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed linear stray-field immune mode (-200 option code), SENT/PWM protocol support, functional safety architecture, and real-world sensor interface design context.
Technical Context
The MLX90372GGO-ACC-200-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute linear position decoding without mechanical contact. Its dual-die TSSOP-16 package provides full redundancy with isolation resistance ≥4 MΩ between dice.
It supports programmable linear transfer characteristics using 4- or 8-point piecewise linear (PWL) interpolation and implements SAE J2716 APR2016 SENT with Secure Sensor format, including CRC, error codes, and user-defined data fields. The device uses asynchronous angle acquisition at ~588 µs per measurement in linear stray-field immune mode.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - Requires separate 100 nF ceramic capacitors to ground for noise suppression. |
| 2, 10, 16 | VSS1 / VSS2 (analog/digital) | Isolated ground domains - Prevents cross-talk between redundant signal paths; must be routed separately on PCB. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90372GGO-ACE-200-RE | ACE revision replaces ACC; improved ESD robustness and updated firmware stack. | Same linear stray-field immune functionality; preferred for new designs per datasheet Table 2. | Select ACE-200 for production ramp; ACC-200 remains available but not recommended for new designs. |
| MLX90371GGO-ACE-200-RE | Single-die variant in same TSSOP-16 package; no inter-die isolation or dual outputs. | Lacks redundancy and ASIL-C SEooC qualification; suitable only for non-safety-critical linear sensing. | Use only where cost sensitivity outweighs functional safety requirements; cannot substitute in ASIL-B/C systems. |

The MLX90372GGO-ACC-200-SP uses a TSSOP-16 package with full dual-die redundancy. It has 16 terminals, including two independent VDD/VSS/VDEC/OUT sets plus test and input pins. Pinout details are defined in Section 3.2 of the datasheet, with isolation resistance ≥4 MΩ between dice.
Does the MLX90372GGO-ACC-200-SP support SENT or PWM output?
Yes, the MLX90372GGO-ACC-200-SP supports both SENT (SAE J2716 APR2016 compliant) and PWM output modes, selectable via end-user programming. SENT includes Secure Sensor format with CRC, error codes, and 48-bit ID; PWM supports configurable duty cycle and frequency per Section 11.2.
What does the "-200" option code signify for the MLX90372GGO-ACC-200-SP?
The "-200" option code specifies Linear Stray-field Immune Mode, validated per datasheet Section 8.3. This configuration optimizes magnetic front-end filtering and signal conditioning to maintain accuracy in environments with external magnetic interference, such as near motors or solenoids.
Is the MLX90372GGO-ACC-200-SP certified for automotive safety standards?
Yes, the MLX90372GGO-ACC-200-SP is ISO 26262 ASIL-C Safety Element out of Context (SEooC) and AEC-Q100 qualified. These certifications apply to the ACC revision and are documented in Sections 14 and Ordering Information of the datasheet, supporting its use in ASIL-B/C system architectures.
Can the MLX90372GGO-ACC-200-SP be used for rotary position sensing?
No-the MLX90372GGO-ACC-200-SP is configured exclusively for linear position sensing with stray-field immunity. Rotary applications require option codes -100, -300, or -500. Using -200 in rotary setups results in degraded accuracy and invalid calibration; refer to Section 8.3 for mode-specific validation.
