Product details
Overview
MLX90372GGO-ACC-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position processor IC for absolute rotary and linear position sensing. It delivers SENT or PWM output, operates from -40°C to +160°C, supports ISO26262 ASIL-C safety element out of context, and is AEC-Q100 qualified for automotive throttle and pedal position systems.
For engineers reviewing the MLX90372GGO-ACC-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), SENT/PWM timing modes, stray-field robustness, programmable transfer characteristics, and functional safety architecture details critical for automotive sensor design.
Technical Context
The MLX90372GGO-ACC-300-SP implements dual-die full redundancy in TSSOP-16 packaging with isolated analog grounds (VSS1/VSS2) and independent supply/decoupling pins per die. Its Triaxis® front end measures Bx, By, and Bz components to compute absolute angle or linear displacement without mechanical contact.
It supports SAE J2716 APR2016 SENT with secure sensor format (48-bit ID option), configurable PWM output, and programmable piecewise linear (PWL) transfer curves-up to 32 points. Diagnostic cycle time is 20 ms for digital diagnostics and 34 μs for analog diagnostics in asynchronous mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - Enables under-hood automotive deployment without external thermal derating. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) - Matches standard 5 V automotive ECUs; battery mode supports 6–18 V. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - SENT provides error codes and user-defined values; PWM offers deterministic timing for control loops. |
| Accuracy (Legacy Mode) | ±0.3° typical angular error - Validated for -300 option code in standard rotary/linear applications per datasheet Section 9.5. |
| Supply Current | 8.0–10.5 mA - For single-die-equivalent operation; dual-die TSSOP-16 draws ~2× this value. |
| Safety Certification | ISO26262 ASIL-C SEooC - Enables integration into ASIL-B/C systems without requiring additional hardware safety mechanisms. |
| Package | TSSOP-16 - Dual-die redundant layout with isolation resistance ≥4 MΩ between dice per Table 9. |
Pinout & Package
TSSOP-16 package with full redundancy: two independent dies sharing no analog/digital signal paths except shared VSS connection at pin 16 (digital ground die1); isolation confirmed via ≥4 MΩ resistance between VSS1 and VSS2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require separate 100 nF ceramic capacitors to VSS for noise immunity. |
| 2, 10 | VSS1 / VSS2 | Analog ground per die - electrically isolated; must be routed separately on PCB to maintain redundancy integrity. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable fault-containment during overvoltage events. |
| 6, 15 | OUT2 / OUT1 | Redundant digital outputs - support cross-checking or fail-safe voting logic in safety-critical systems. |
| 4, 5, 12, 13 | Input1 / Test2 / Input2 / Test1 | Test/application pins - internally grounded in production; connect to PCB ground for EMC compliance. |
| 7, 14 | N.C. | No-connect pins - must remain unconnected; not bonded internally. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously - enables true absolute position decoding from a single moving magnet without multi-chip alignment. |
| Programmable PWL Transfer | Up to 32-point piecewise linear curve - eliminates external lookup tables and allows custom calibration for non-uniform mechanical travel. |
| SENT Secure Sensor Format | Includes CRC, error flags, and 48-bit ID - supports traceability and diagnostic confidence in vehicle networks. |
| Stray-Field Immunity (Legacy Mode) | Validated for -300 option code - maintains accuracy in environments with nearby motors or solenoids without shielding. |
| Fast Startup Time | 11.2–12.4 ms safe startup - ensures rapid system readiness after ignition, meeting automotive cold-start timing requirements. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|

IC Role / Device Role / Timing Role: Linear position sensor using legacy -300 configuration with programmable 16-point PWL to match nonlinear spring characteristics. Use Value: Single-die-equivalent current draw (8–10.5 mA) enables low-power continuous monitoring without draining chassis batteries. |
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-SP | ACE revision replaces ACC; improved startup time (11.2–12.4 ms vs. ACC's unspecified), enhanced ESD robustness, and updated memory ECC. | Same TSSOP-16 package and -300 legacy mode functionality - suitable for new designs requiring long-term availability. | Select ACE-300 for new designs; ACC-300 remains in production but is not recommended for new projects per Melexis documentation. |
| MLX90371GGO-ACC-300-SP | Single-die variant in same TSSOP-16 package; lacks dual-die isolation and redundancy; lower supply current (8–10.5 mA vs. ~2× for MLX90372). | Applicable where ASIL-C SEooC or hardware redundancy is not required - e.g., non-safety-critical industrial actuators. | Choose MLX90371 only if cost and power are prioritized over functional safety certification and fault tolerance. |
Compared with MLX90372GGO-ACC-300-SP, the ACE-300 alternative offers documented lifecycle support and tighter startup timing, while the MLX90371GGO-ACC-300-SP reduces cost and power at the expense of ISO26262 ASIL-C qualification and die-level redundancy.

FAQ
What is the operating temperature range of the MLX90372GGO-ACC-300-SP?
The MLX90372GGO-ACC-300-SP operates from -40°C to +160°C, validated per AEC-Q100 Grade 0 specifications. This range supports under-hood placement in modern ICE and hybrid powertrains without external thermal management, and is explicitly confirmed for the ACC-300 option code in the official datasheet revision 8.
Does the MLX90372GGO-ACC-300-SP support both SENT and PWM outputs?
Yes, the MLX90372GGO-ACC-300-SP supports selectable SENT (SAE J2716 APR2016 compliant) or PWM output via end-user programming. SENT provides secure sensor format with CRC and error reporting; PWM delivers deterministic timing for real-time control loops - both modes are fully supported in the ACC-300 configuration.
Is the MLX90372GGO-ACC-300-SP certified for functional safety applications?
Yes, the MLX90372GGO-ACC-300-SP is qualified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). This certification applies directly to the ACC-300 variant and enables its use in ASIL-B or ASIL-C systems when integrated with appropriate system-level safety mechanisms per the Melexis Safety Manual.
What package type does the MLX90372GGO-ACC-300-SP use, and why is it significant?
The MLX90372GGO-ACC-300-SP uses the TSSOP-16 package, which houses two fully redundant dies with isolated analog grounds (VSS1/VSS2) and independent supply/decoupling paths. This physical separation enables hardware-level fault containment - a requirement for ASIL-C compliance and fail-operational behavior in automotive safety systems.
How does the MLX90372GGO-ACC-300-SP achieve stray magnetic field immunity?
The MLX90372GGO-ACC-300-SP achieves stray-field immunity through its Triaxis® architecture and differential front-end design, validated for the -300 option code in standard rotary/linear configurations. It rejects common-mode interference from nearby motors or solenoids without requiring external shielding - a capability confirmed in Section 8.4 of the datasheet.
