Product details
Overview
MLX90422GVE-ADD-030-RX 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 processing, SENT (SAE J2716 APR2016) output, and operates from −40°C to +160°C in SMP-3 package. It delivers 12-bit angular resolution with ±0.5° total accuracy over temperature and supports programmable linearization up to 17 points.
For engineers reviewing the MLX90422GVE-ADD-030-RX datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT timing behavior, magnetic field sensitivity thresholds, ASIL B safety architecture, and packaging-specific design meaning for automotive pedal and throttle position systems.
Technical Context
The MLX90422GVE-ADD-030-RX implements Triaxis® Hall sensing to resolve Bx, By, and Bz components simultaneously, enabling robust absolute angle calculation from rotating magnets without mechanical contact. Its on-chip DSP performs real-time linearization using up to 17 user-programmable transfer points and supports dual-filtering configurations (Filter 0/1/2) to balance latency and noise rejection.
It outputs SENT frames in A.3 (H.4) format with fixed 3 μs tick time, delivering 12-bit angular data plus diagnostics in each frame. The device features dual independent diagnostic cycles (DCTANA = 10.4 ms, DCTDIG = 19.7 ms), safe startup time ≤33 ms, and operates with supply current of 7.5–10.0 mA at 4.5–5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT per SAE J2716 APR2016, A.3 (H.4) format - enables deterministic, error-coded digital transmission to ECU with CRC and diagnostics. |
| Angular Accuracy | ±0.5° total error over −40°C to +160°C - ensures reliable pedal/throttle position feedback under full automotive thermal stress. |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard automotive 5 V rail; supports extended operation up to 5.5 V at 180°C for SMP-3 package. |
| Startup Time | Tstup ≤ 5.93 ms - delivers first valid angle within 6 ms after power-on, meeting fast-response requirements in drivetrain control. |
| Latency | 1.32–2.03 ms (synchronous mode) - defines maximum delay between magnet movement and SENT output update for closed-loop stability. |
| Magnetic Sensitivity | Bnorm = 10–20 mT (X-Y mode); Bz ≤ 126 mT - sets minimum magnet strength and air-gap design constraints for rotary applications. |
| Functional Safety | ISO 26262 ASIL B SEooC - provides documented safety mechanisms (watchdog, memory ECC, voltage monitoring) for integration into ASIL B systems without additional hardware. |
Pinout & Package
SMP-3 is a PCB-less single-mold package with 3 terminals: VDD (supply), OUT (open-drain SENT output), and VSS (ground). Its compact form factor enables direct mounting onto flexible substrates or metal carriers in space-constrained throttle/pedal assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VDD | Supply input | Accepts 4.5–5.5 V; internal regulator generates 3.3 V analog rail (VDEC = 3.2–3.4 V) - decoupling not required externally due to integrated capacitance. |
| 2: OUT | Digital output | Open-drain SENT signal compliant with SAE J2716; VOH ≥ 4.1 V @ 0.1 mA, VOL ≤ 0.5 V @ 0.52 mA - interfaces directly with 5 V ECU inputs using external pull-up. |
| 3: VSS | Ground reference | Common return for supply and output; broken-wire detection triggers BVSSPU = 99.5–100% VDD if open - enables fail-safe diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Hall Sensing | Simultaneous Bx/By/Bz measurement enables true 3D magnetic field vector resolution - eliminates need for external concentrators or multi-sensor assemblies in rotary position designs. |
| Programmable 17-Point Linearization | User-configurable transfer curve compensates for magnet nonlinearity and mechanical eccentricity - achieves ±0.5° accuracy without post-assembly calibration. |
| SENT Output with Diagnostics | Embedded CRC, field validity flags, and broken-wire detection (BVSSPU/BVDDPU) provide real-time fault reporting - reduces ECU software overhead for sensor health monitoring. |
| AEC-Q100 Grade 0 Qualification | Validated for −40°C to +160°C operation with high-temp extension to +180°C (≤250 h) - supports under-hood placement in modern electrified powertrains. |
| ASIL B Safety Element out of Context | Includes hardware watchdog (IWD/AWD), memory ECC, voltage monitors, and diagnostic cycle timers - allows reuse in ASIL B systems with documented safety case integration. |
Applications

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-RX | Single-die variant with identical SMP-3 package, SENT A.3 output, and 12-bit resolution but lacks dual-filtering and reduced diagnostic depth (no DCTANA). | Targeted at cost-sensitive ASIL A systems where full ASIL B diagnostics are not required. | Select when functional safety level can be reduced to ASIL A and latency tolerance exceeds 2.03 ms. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor with I²C output, 12-bit resolution, and −40°C to +125°C rating - no SENT support, no ASIL B certification, lower temperature capability. | Suitable for non-safety-critical industrial or consumer rotary encoders where I²C interface suffices. | Choose only for non-automotive applications lacking SENT bus infrastructure or ASIL B compliance needs. |
Compared with MLX90422GVE-ADD-030-RX, the MLX90421GVE-ADD-030-RX reduces safety coverage and filtering flexibility but lowers BOM cost, while the TLV493DW2B6HTSA1 omits SENT, ASIL B, and high-temp operation - making MLX90422GVE-ADD-030-RX the sole option for ASIL B-compliant, SENT-based, 160°C rotary sensing.

The MLX90422GVE-ADD-030-RX is qualified per AEC-Q100 Grade 0 for continuous operation from −40°C to +160°C. With SMP-3 packaging, it supports high-temperature extension up to +180°C for ≤250 hours, validated under defined bias and thermal cycling conditions per datasheet Section 4.1.
Does the MLX90422GVE-ADD-030-RX require external decoupling capacitors?
No. The MLX90422GVE-ADD-030-RX in SMP-3 package integrates internal decoupling capacitance, eliminating the need for external VDD/VSS bypass capacitors. This simplifies PCB layout and supports direct mounting on flex circuits or metal carriers without discrete passives.
What SENT protocol version does the MLX90422GVE-ADD-030-RX implement?
The MLX90422GVE-ADD-030-RX implements SENT per SAE J2716 APR2016, specifically using the Single Secure Sensor A.3 (H.4) format. It outputs fixed-length frames with 3 μs tick time, 287-tick duration, and includes CRC, status nibbles, and programmable diagnostics fields.
How is functional safety implemented in the MLX90422GVE-ADD-030-RX?
The MLX90422GVE-ADD-030-RX achieves ISO 26262 ASIL B as a Safety Element out of Context (SEooC) via hardware-level mechanisms: intelligent watchdog (IWD), absolute watchdog (AWD), memory ECC, supply/ground monitoring, and dual diagnostic cycles (DCTANA/DCTDIG). These are documented in the Melexis Safety Manual Rev. 004.
Can the MLX90422GVE-ADD-030-RX measure linear position?
Yes. Though optimized for angular rotary sensing, the MLX90422GVE-ADD-030-RX supports linear position mode via magnetic configuration selection. Its Triaxis® front end resolves Bx, By, and Bz components, allowing programmable axis selection (e.g., X-Z or Y-Z) to compute displacement from moving magnets in push-pull or side-slide arrangements.
