Product details
Overview
MLX90422GVE-ADD-030-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary position sensing. It integrates a 3-axis Hall front end, DSP-based signal conditioning, programmable linear transfer characteristic (up to 17 points), SENT output per SAE J2716 APR2016, and operates from −40 °C to +160 °C in SMP-3 package. It delivers high-accuracy non-contact angular measurement in automotive throttle and pedal systems.
For engineers reviewing the MLX90422GVE-ADD-030-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SMP-3 package mapping, SENT timing compliance, ASIL B safety context, and real-world automotive positioning use cases - all confirmed from Melexis Revision 004 documentation.
Technical Context
The MLX90422GVE-ADD-030-RE implements Triaxis® Hall technology to measure Bx, By, and Bz components simultaneously, enabling robust absolute angle calculation from magnet motion. Its on-chip DSP supports user-programmable linearization with up to 17-point transfer curves and configurable SENT frame formats (A.3/H.4).
It operates in continuous synchronous acquisition mode by default, delivering SENT frames every 861–905 μs with fixed 3 μs tick time and two angle acquisitions per frame. The device includes integrated diagnostics (analog/digital DCT cycles of 10.4 ms and 19.7 ms), under/over-voltage detection, and safe startup within 5–33 ms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5–5.5 V - Stable operation across automotive battery transients; internal VDEC regulated to 3.3 V ±0.1 V. |
| Operating Temperature | −40 °C to +160 °C - Qualified AEC-Q100 Grade 0; supports extended 180 °C exposure for ≤250 h in SMP-3 package. |
| Output Interface | SENT (SAE J2716 APR2016) - Open-drain digital output with 3 μs tick time, A.3/H.4 format, and built-in CRC error detection. |
| Angle Accuracy | ±0.5° typical over full range - Achieved via on-chip DSP linearization and IMC-enhanced magnetic field concentration. |
| Startup Time | 5.93 ms to first valid angle - Includes internal initialization and SENT frame synchronization; safe startup window up to 33 ms. |
| Latency | 1.32–2.03 ms average - Determined by filter configuration and frame timing; critical for real-time throttle control loop response. |
| Magnetic Sensitivity | BNorm = 10–20 mT - Valid for X-Y, X-Z, or Y-Z sensing modes; enables compact magnet design with low-field tolerance. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Power supply input | Accepts 4.5–5.5 V; powers internal regulator (VDEC = 3.3 V) and analog/digital blocks. |
| 2: OUT | Digital SENT output | Open-drain SENT signal compliant with SAE J2716; requires external pull-up to Vext (≤VDD). |
| 3: VSS | Ground reference | Common return path for supply and signal; must be low-impedance for EMC and accuracy. |

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 |
|---|---|---|---|
| MLX90421GVE-ADD-030-RE | Single-die variant with identical SMP-3 package, SENT interface, and 17-point linearization but lacks dual-die redundancy and ASIL B certification. | Targeted at non-safety-critical industrial position 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-WSFT | 12-bit I²C angle sensor with integrated magnet; no SENT output, no ASIL qualification, lower temperature rating (−40 °C to +125 °C). | Suitable for consumer or light-industrial rotary encoders where automotive-grade reliability and protocol compatibility are not required. | Choose only for non-automotive designs needing simple I²C integration and lower BOM count - not a drop-in replacement. |
Compared with MLX90422GVE-ADD-030-RE, the MLX90421GVE-ADD-030-RE reduces safety overhead but sacrifices fault tolerance, while the AS5600-WSFT trades automotive robustness and SENT compatibility for ease of I²C integration and lower cost in non-safety contexts.

FAQ
What is the operating temperature range of the MLX90422GVE-ADD-030-RE?
The MLX90422GVE-ADD-030-RE is qualified for continuous operation from −40 °C to +160 °C and supports limited exposure up to +180 °C for ≤250 hours - validated per AEC-Q100 Grade 0 and documented in Revision 004 datasheet Section 4.1. This range applies specifically to the SMP-3 (VE) package used in MLX90422GVE-ADD-030-RE.
Does the MLX90422GVE-ADD-030-RE support SENT protocol variants beyond A.3/H.4?
No - the MLX90422GVE-ADD-030-RE is factory-configured for SENT Single Secure Sensor A.3 (H.4) format only, as specified in its ordering code ADD-030 and confirmed in Section 11.1 of the datasheet. It does not support A.1 (dual-throttle) or other SENT variants without reprogramming, which requires Melexis-approved tools and is not enabled in standard delivery configuration.
How many pins does the MLX90422GVE-ADD-030-RE have, and what are their functions?
The MLX90422GVE-ADD-030-RE uses the SMP-3 package with exactly three terminals: Pin 1 is VDD (4.5–5.5 V supply), Pin 2 is OUT (open-drain SENT output), and Pin 3 is VSS (ground). This 3-pin configuration is confirmed in Table 7 (Section 3.4) of the datasheet and excludes test or NC pins found in SOIC-8 or TSSOP-16 variants.
Is the MLX90422GVE-ADD-030-RE certified to ISO 26262 ASIL B?
Yes - the MLX90422GVE-ADD-030-RE is certified as a Safety Element out of Context (SEooC) for ISO 26262 ASIL B, with documented safety mechanisms including CRC protection, watchdog timers, voltage monitoring, and diagnostic cycles. This is explicitly stated in the Features section and elaborated in Section 14 of the Revision 004 datasheet.
What magnetic field strength is required for reliable operation of the MLX90422GVE-ADD-030-RE?
The MLX90422GVE-ADD-030-RE requires a useful magnetic flux density norm (BNorm) between 10 mT and 20 mT, depending on sensing mode (X-Y, X-Z, or Y-Z), as defined in Table 18. Field thresholds are programmable: BTH_LOW (2–30 mT) and BTH_HIGH (70–126 mT), with typical settings recommended in Section 13.5.5 for robust detection.
