Product details
Overview
MLX90372GGO-ACC-300-RE from Melexis is a Triaxis® monolithic magnetic position processor IC for absolute rotary and linear position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, and SENT/PWM output. Operating from -40°C to +160°C with AEC-Q100 qualification and ISO 26262 ASIL-C safety certification, it delivers robust non-contact sensing in automotive throttle, pedal, and steering wheel position systems.
For engineers reviewing the MLX90372GGO-ACC-300-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die redundancy, SENT v4.0 (SAE J2716 APR2016) compliance, programmable 4–32-point transfer characteristic, stray-field immunity in legacy mode, and 8.0–10.5 mA supply current at 4.5–5.5 V.
Technical Context
The MLX90372GGO-ACC-300-RE implements a dual-die TSSOP-16 architecture with isolated analog grounds (VSS1/VSS2) and independent supply/decoupling pins per die, enabling full hardware redundancy for functional safety applications. Its Triaxis® Hall sensor measures Bx, By, and Bz components simultaneously to compute absolute angular or linear position without mechanical wear.
It supports two timing modes: asynchronous acquisition (528–588 µs measurement period) for PWM and continuous SENT, and synchronous acquisition aligned to SENT frame timing (930–960 µs frame period with two angles/frame). Output is configurable as SENT (3 µs tick, Secure Sensor format with CRC and diagnostics) or PWM (programmable duty cycle), both with fail-safe state activation within 9.8–34.6 ms after fault detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including engine control and transmission modules. |
| Supply Voltage | 4.5–5.5 V - regulated mode operation; supports battery-supplied 6–18 V via internal regulation. |
| Supply Current | 8.0–10.5 mA - low power consumption enables use in always-on vehicle subsystems without thermal penalty. |
| Output Protocol | SENT (SAE J2716 APR2016) or PWM - SENT provides 12-bit position + diagnostics in 3 µs tick frames; PWM offers analog-compatible interface. |
| Accuracy | ±0.3° typical angular error - achieved via on-chip DSP compensation and factory-trimmed transfer characteristics. |
| Safety Certification | ISO 26262 ASIL-C SEooC - enables integration into ASIL-B/C system architectures without requiring additional safety mechanisms at IC level. |
| Package | TSSOP-16 - dual-die layout with isolation resistance >4 MΩ between dice, supporting redundant signal paths. |
Pinout & Package
TSSOP-16 package with dual-die redundancy, RoHS-compliant, 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to stabilize internal analog regulators. |
| 2, 10, 16 | VSS1 / VSS2 / VSS1 | Separate analog/digital ground returns per die - mandatory separation prevents noise coupling between redundant channels. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enables power domain isolation for fault containment. |
| 4, 12 | Input1 / Input2 | Multi-function test/application pins - internally grounded in production; used for factory calibration and optional NTC/gateway functions. |
| 5, 13 | Test2 / Test1 | Factory test access points - not intended for end-user connection; tie to GND for EMC compliance. |
| 6, 15 | OUT2 / OUT1 | Redundant digital outputs - support cross-checking in safety-critical systems; both deliver identical SENT/PWM frames. |
| 7, 14 | N.C. | No-connect pins - must be left unconnected per datasheet; PCB pads may be omitted. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx/By/Bz measurement enables single-chip absolute angle decoding without external concentrators or complex magnet assemblies. |
| Programmable Transfer Curve | Configurable 4-, 8-, 16-, or 32-point PWL mapping allows precise linearization for custom mechanical linkages or non-uniform travel ranges. |
| Stray-Field Immunity | Legacy (-300) mode maintains ±0.3° accuracy under 10 mT external DC fields - critical for EV powertrain and ADAS proximity environments. |
| Dual-Die Redundancy | Independent signal chains with isolated grounds and supplies enable lockstep comparison for ASIL-C diagnostic coverage. |
| Secure SENT Output | Embedded CRC, status flags, and user-defined data fields provide tamper-resistant position reporting with real-time fault indication. |

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-300-RE | Same TSSOP-16 package and pinout; ACE revision replaces ACC with enhanced ESD robustness and updated firmware. | Identical functional scope; preferred for new designs per Melexis ordering guide. | Select ACE-300 for production ramp; ACC-300 remains available but not recommended for new designs. |
| MLX90371GGO-ACE-300-RE | Single-die variant in same TSSOP-16 package; lacks dual-die isolation and ASIL-C SEooC certification. | Lower-cost option for non-safety-critical applications like HVAC flap control or seat position. | Choose MLX90371 only when ASIL-C compliance and hardware redundancy are not required. |
Compared with MLX90372GGO-ACC-300-RE, the ACE-300 revision offers improved manufacturing yield and long-term firmware support, while the MLX90371GGO-ACE-300-RE reduces BOM cost by eliminating redundant circuitry - making it suitable for cost-sensitive industrial motion control where functional safety is not mandated.

FAQ
What is the primary sensing technology used in the MLX90372GGO-ACC-300-RE?
The MLX90372GGO-ACC-300-RE uses Melexis' proprietary Triaxis® Hall technology, which measures all three orthogonal components (Bx, By, Bz) of magnetic flux density. This enables true 3D field vector analysis for absolute angular or linear position decoding without external magnetic concentrators. The MLX90372GGO-ACC-300-RE processes these signals on-chip using dedicated analog front-end and DSP blocks to deliver calibrated output via SENT or PWM.
Does the MLX90372GGO-ACC-300-RE support functional safety standards?
Yes, the MLX90372GGO-ACC-300-RE is certified as an ISO 26262 ASIL-C Safety Element out of Context (SEooC) and qualified to AEC-Q100 Grade 0. Its TSSOP-16 dual-die architecture provides hardware redundancy with isolated grounds and supplies, enabling diagnostic coverage for single-event faults. The MLX90372GGO-ACC-300-RE also includes built-in watchdog timers (IWD/AWD), memory ECC, and SENT frame CRC to meet ASIL-C requirements without external safety monitors.
What output protocols does the MLX90372GGO-ACC-300-RE support?
The MLX90372GGO-ACC-300-RE supports two configurable digital output protocols: SENT (SAE J2716 APR2016 compliant, 3 µs tick, Secure Sensor format) and PWM (pulse-width modulated, programmable frequency and duty cycle). SENT output includes 12-bit position data, status flags, CRC, and up to 48 bits of user-defined ID. The MLX90372GGO-ACC-300-RE allows runtime switching between protocols via programming, with no hardware change required.
What package type and pin count does the MLX90372GGO-ACC-300-RE use?
The MLX90372GGO-ACC-300-RE uses a RoHS-compliant TSSOP-16 package with 0.65 mm pitch and dual-die construction. It features 16 leads including redundant VDD/VSS/VDEC/OUT pins per die, two isolated ground domains, and dedicated test/input pins. The MLX90372GGO-ACC-300-RE's pinout matches Melexis' standard TSSOP-16 layout for Triaxis® devices, ensuring drop-in compatibility with existing PCB footprints designed for MLX90372GGO-ACE-300-RE.
Can the MLX90372GGO-ACC-300-RE be programmed for custom transfer characteristics?
Yes, the MLX90372GGO-ACC-300-RE supports end-user programmable transfer characteristics using piecewise linear (PWL) interpolation with 4, 8, 16, or 32 breakpoints. These points define the mapping between raw magnetic field input and output position value, allowing compensation for mechanical nonlinearity, magnet misalignment, or custom travel profiles. Programming is performed via Melexis' PTC tool using the Input/Test pins, and settings are stored in on-chip NVRAM - the MLX90372GGO-ACC-300-RE retains configuration across power cycles.
