Product details
Overview
MLX90422GVS-ADD-030-SP from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing, featuring SENT output per SAE J2716 APR2016, programmable 17-point linear transfer characteristic, and operation from −40°C to +160°C in DMP-4 package. It uses Bx/By/Bz field components for robust non-contact angle measurement up to 360°, with ISO26262 ASIL B safety element out of context and AEC-Q100 Grade 0 qualification.
For engineers reviewing the MLX90422GVS-ADD-030-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, pin-level design meaning, real-world automotive use cases, and validated alternative options for pedal, throttle, and steering position sensing systems.
Technical Context
The MLX90422GVS-ADD-030-SP integrates a Triaxis® Hall front end, analog-to-digital signal conditioner, and DSP-based signal processing engine to compute absolute angular position from three orthogonal magnetic flux components (Bx, By, Bz). Its programmable sensing mode selects axis combinations (e.g., X-Y for rotary, X-Z for linear) to match magnet geometry and motion path.
It outputs SENT frames in Single Secure Sensor A.3 (H.4) format with fixed 3 μs tick time, 287-tick frame length (861–905 μs), and dual diagnostics cycles (10.4 ms analog, 19.7 ms digital). Startup time to first valid angle is 5.93 ms, with average latency of 1.32–2.03 ms depending on filter configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format - enables deterministic, error-coded transmission to automotive ECUs with CRC and diagnostic nibbles. |
| Operating Temp | −40°C to +160°C - supports under-hood and transmission applications without external cooling or derating. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard automotive 5 V supplies; internal 3.3 V regulated analog rail (VDEC). |
| Supply Current | 7.5–10.0 mA - single-die power consumption enabling low-heat dissipation in compact DMP-4 package. |
| Angle Accuracy | ±0.5° typical INL over full scale - ensures high-fidelity feedback for closed-loop control in throttle and pedal systems. |
| Magnetic Range | BNorm = 10–20 mT - defines usable magnetic signal envelope for reliable detection with common NdFeB magnets at air gaps ≤ 3 mm. |
| Startup Time | 5.93 ms to first valid angle - meets fast-response requirements in driver-assist and active safety subsystems. |
Pinout & Package
DMP-4 (Dual Mold Package) is a PCB-less, 4-pin surface-mount package with integrated decoupling capacitance, optimized for space-constrained automotive sensors. Pin 1 = VSS (ground), Pin 2 = VDD (supply), Pin 3 = OUT (open-drain SENT output), Pin 4 = VSS (ground).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for both analog and digital domains; dual ground pins improve EMC immunity and reduce ground bounce in noisy environments. |
| 2 | VDD | 5 V supply input; internally regulated to 3.3 V for analog circuitry - eliminates need for external LDO in most designs. |
| 3 | OUT | Open-drain SENT output; requires external pull-up to Vext (typically VDD); compliant with SAE J2716 voltage thresholds (VOL ≤ 0.5 V, VOH ≥ 4.1 V). |
| 4 | VSS | Second ground terminal - provides low-inductance return path for output current and enhances noise rejection in high-EMI zones. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field analysis - eliminates mechanical alignment sensitivity and supports off-axis magnet placement. |
| Programmable Transfer Curve | Up to 17-point user-defined linearization table - corrects nonlinearity from magnet geometry and air gap variation without host MCU intervention. |
| ISO26262 ASIL B SEooC | Pre-certified safety element out of context - reduces functional safety validation effort for ASIL B systems like electronic throttle control. |
| AEC-Q100 Grade 0 | Qualified for 160°C ambient operation - validated for direct mounting on engines, transmissions, and brake modules without thermal shielding. |
| Dual-Diagnostic Cycles | Independent 10.4 ms analog and 19.7 ms digital diagnostics - detects open-circuit, short-to-rail, and magnetic fault conditions within defined safety time intervals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GVS-ADD-030-SP | Single-die DMP-4 variant with identical SENT protocol, 16-point linearization, and same −40°C to +160°C rating - lacks dual-die redundancy and ASIL B SEooC certification. | Targeted at non-safety-critical linear/rotary sensing where cost optimization outweighs functional safety requirements. | Select when ASIL B compliance is not mandated and diagnostic coverage can be implemented externally. |
| AMS AS5600-WSCT | 12-bit I²C output, ±3° accuracy, −40°C to +125°C rating - no SENT interface, no ASIL B certification, no programmable transfer curve beyond 2-point offset/gain. | Suitable for consumer-grade rotary encoders or industrial HMI dials where automotive reliability and protocol compliance are not required. | Choose only for non-automotive applications with I²C infrastructure and relaxed accuracy/temperature/safety demands. |
Compared with MLX90422GVS-ADD-030-SP, MLX90421GVS-ADD-030-SP offers lower system cost but forfeits ASIL B readiness and dual-die fault tolerance, while AMS AS5600-WSCT provides simpler integration at the expense of automotive-grade robustness, SENT compatibility, and precision linearization capability.
