| Supply Voltage | 4.5 V to 5.5 V (regulated mode) - compatible with standard 5 V automotive ECUs; supports battery mode up to 18 V. |
| Output Interface | SENT (SAE J2716 APR2016) or PWM - SENT enables secure sensor data frames with CRC, diagnostics, and user-defined values. |
| Accuracy (Rotary) | ±0.3° typical total error - includes INL, DNL, temperature drift, and magnetic hysteresis over full temperature range. |
| Stray-Field Immunity | High-field variant (-500 code) - designed for operation in strong external magnetic fields up to ±1 T without performance degradation. |
| Safety Certification | ISO26262 ASIL-C SEooC - provides safety mechanisms (watchdog, memory ECC, diagnostic cycles) for integration into ASIL-B/C systems. |
| Package | TSSOP-16 - dual-die layout enables full hardware redundancy; isolation resistance ≥4 MΩ between dies supports fault-tolerant architectures. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: two independent sensor channels (die1/die2), each with dedicated supply, ground, decoupling, and output pins. Requires PCB-level grounding of all unused Input/Test pins for optimal EMC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 / VDEC2 | Decoupling pin (per die) | Connects to local 100 nF ceramic capacitor to stabilize internal analog regulator (3.3 V); critical for noise immunity. |
| VDD1 / VDD2 | Supply input (per die) | Accepts 4.5–5.5 V regulated supply; dual inputs enable independent power domain monitoring for redundancy validation. |
| VSS1 / VSS2 (analog & digital) | Ground reference (per die) | Separate analog/digital ground pins per die reduce coupling noise; isolation resistance ≥4 MΩ enables fault detection. |
| OUT1 / OUT2 | Digital output (per die) | Push-pull SENT/PWM outputs; support independent diagnostics and cross-checking for safety-critical comparison logic. |
| Input1 / Input2 / Test1 / Test2 | Test or gateway interface | Internally grounded in application; must be externally tied to PCB ground to prevent floating nodes and EMC issues. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously to compute absolute angle/position without external concentrators - enables compact, low-profile magnet placement. |

FAQ
What is the operating temperature range of the MLX90372GGO-ACC-500-RE?
The MLX90372GGO-ACC-500-RE is rated for operation from -40°C to +160°C, meeting AEC-Q100 Grade 0 requirements. This range supports under-hood automotive applications such as throttle bodies and brake pedals where ambient temperatures exceed 125°C. The specification is validated across supply voltage (4.5–5.5 V) and includes full functionality of SENT output, diagnostics, and stray-field immunity at both extremes.
Does the MLX90372GGO-ACC-500-RE support both SENT and PWM output modes?
Yes, the MLX90372GGO-ACC-500-RE supports selectable SENT (SAE J2716 APR2016 compliant) or PWM output via end-user programming. SENT mode delivers secure sensor frames with CRC, error codes, and user-defined data; PWM mode provides configurable duty cycle for legacy ECU interfaces. Both modes operate within the same timing constraints and retain full diagnostic capability.
What does the "-500" option code signify in MLX90372GGO-ACC-500-RE?
The "-500" option code in MLX90372GGO-ACC-500-RE configures the device for Rotary Stray-field Immune Mode – High Field Variant. It enables operation in external magnetic fields up to ±1 T without accuracy loss, making it suitable for proximity to electric motors, solenoids, or high-current conductors. This setting is factory-programmed and distinct from -100 (low-field) or -300 (legacy) variants.
Is the MLX90372GGO-ACC-500-RE pin-compatible with other MLX90372 package variants?
No - the MLX90372GGO-ACC-500-RE uses the TSSOP-16 package with dual-die layout and 16-pin footprint, which is not pin-compatible with SOIC-8 (8-pin) or DMP-4 (4-pin) variants. Pin assignments differ significantly: TSSOP-16 provides separate VDD/VSS/VDEC/OUT per die, while SOIC-8 and DMP-4 share resources. PCB redesign is required when switching packages.
How does the dual-die architecture of MLX90372GGO-ACC-500-RE support ISO26262 ASIL-C compliance?
The MLX90372GGO-ACC-500-RE achieves ASIL-C as a Safety Element out of Context (SEooC) through its dual-die TSSOP-16 implementation: independent power, ground, and signal paths enable cross-die comparison; isolation resistance ≥4 MΩ between dice supports fault detection; and integrated diagnostics (IWD, AWD, memory ECC) provide coverage for transient and permanent faults - all documented in Melexis' certified safety manual.
