Product details
Overview
MLX90422GVS-ADD-038-TU 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, and SENT (SAE J2716 APR2016) output. Key confirmed parameters: operating temperature −40°C to +160°C, supply voltage 4.5–5.5 V, SENT tick time fixed at 3 µs, angular accuracy ≤ ±0.5° over full range, and DMP-4 (VS) package with 4-pin leaded configuration.
For engineers reviewing the MLX90422GVS-ADD-038-TU datasheet, pinout, applications, or equivalent options, this page delivers verified functional identity, DMP-4 package mapping, SENT timing compliance, ASIL B safety context, and automotive-grade magnetic field sensitivity data - all directly traceable to Melexis Revision 004 documentation.
Technical Context
The MLX90422GVS-ADD-038-TU implements Triaxis® Hall sensing to resolve Bx, By, and Bz components simultaneously, enabling robust absolute angle calculation from magnet rotation. Its on-chip DSP supports up to 17-point programmable linearization and dual-filtering modes (Filter 0/1/2), with latency as low as 0.83 ms in asynchronous mode.
It operates exclusively in SENT output mode per SAE J2716 APR2016 A.3 (H.4) format, delivering 12-bit angular data plus diagnostics in frames with fixed 3 µs tick time. The DMP-4 package variant uses internal decoupling and requires no external PCB - pins are VSS, VDD, OUT, VSS - with factory test pins omitted.

Pinout & Package
DMP-4 (VS) is a PCB-less dual-mold package with 4 leads, optimized for direct soldering onto harnesses or flexible substrates. No external decoupling capacitors required - internal regulation and filtering are integrated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for both analog and digital domains; must be connected to system ground |
| 2 | VDD | Primary supply input (4.5–5.5 V); powers internal regulator generating VDEC = 3.3 V |
| 3 | OUT | Open-drain SENT output; requires external pull-up to Vext (typically VDD); transmits encoded angle and diagnostics |
| 4 | VSS | Second ground terminal; improves EMC performance and current return path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3-Axis Sensing | Simultaneous Bx, By, Bz measurement enables true 3D magnetic field reconstruction for absolute angle computation without mechanical stops |
| Programmable Linearization | Up to 17-point user-defined transfer curve compensates for magnet nonlinearity and air-gap variation across production units |
| SENT Diagnostics | Embedded CRC, error codes, and passive broken-wire detection (99.5% VDD on open VSS) reduce need for external monitoring circuitry |
| Dual-Filter Architecture | Selectable Filter 0/1/2 configures latency vs. noise rejection trade-off - e.g., Filter 0 achieves 0.83 ms avg latency; Filter 2 adds stability for harsh EMI environments |
| High-Temp Operation | Validated operation at +180°C ambient for ≤250 h in DMP-4 package, enabling use in engine bay or transmission-mounted 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 |
|---|---|---|---|
| MLX90421GVS-ADD-038-TU | Single-die predecessor with identical DMP-4 package, SENT output, and pinout; lacks ASIL B certification and advanced filtering modes | Not suitable for ASIL B–required systems; limited diagnostic coverage and no high-temp extension support | Select only for cost-sensitive legacy designs where functional safety is not mandated. |
| AMS AS5600-WSCT | 12-bit I²C angle sensor with integrated magnet; no SENT output; lower temp rating (−40°C to +125°C); no ASIL qualification | Requires host MCU for protocol translation and diagnostics; unsuitable for direct ECU integration in automotive powertrain | Appropriate for industrial encoders or consumer robotics where SENT and ASIL B are unnecessary. |
Compared with MLX90422GVS-ADD-038-TU, the MLX90421GVS-ADD-038-TU offers pin-compatible migration but omits safety mechanisms and thermal robustness, while the AMS AS5600-WSCT trades automotive readiness for simpler interface and lower cost - neither provides drop-in replacement capability due to protocol, certification, or environmental gaps.

FAQ
What is the package type and lead count for MLX90422GVS-ADD-038-TU?
The MLX90422GVS-ADD-038-TU uses the DMP-4 (Dual Mold Package) with 4 leads: VSS, VDD, OUT, and VSS. This PCB-less, leaded package is designed for direct harness mounting and requires no external decoupling capacitors. Pinout is fully defined in Melexis datasheet Section 3.3 and validated for automotive harness integration.
Does MLX90422GVS-ADD-038-TU support SENT protocol revision compatibility beyond SAE J2716 APR2016?
No - MLX90422GVS-ADD-038-TU implements only SAE J2716 APR2016-compliant SENT, specifically Single Secure Sensor A.3 (H.4) format. It does not support earlier (2008) or later (2021) revisions. Frame structure, tick time (3 µs), pause pulse handling, and CRC implementation are fixed per this revision and cannot be reconfigured.
Can MLX90422GVS-ADD-038-TU operate at 180°C ambient temperature?
Yes - MLX90422GVS-ADD-038-TU is qualified for +180°C ambient for up to 250 hours when used in DMP-4 (VS) package, per datasheet Table 10. Performance degrades (e.g., reduced magnetic sensitivity, increased latency), but core functionality remains. This extension is not valid for SOIC-8 or TSSOP-16 variants.
What is the maximum angular accuracy specification for MLX90422GVS-ADD-038-TU over its full operating temperature range?
The MLX90422GVS-ADD-038-TU achieves ≤ ±0.5° typical total angular error over 0–360° at −40°C to +160°C, including contributions from INL, DNL, thermal drift, and magnetic hysteresis. This value is measured per datasheet Section 9.2 and assumes calibrated linearization and proper magnet coupling per Melexis application guidelines.
Is MLX90422GVS-ADD-038-TU pin-compatible with other MLX90422 package variants like SOIC-8 or TSSOP-16?
No - MLX90422GVS-ADD-038-TU (DMP-4, 4-pin) is not pin-compatible with SOIC-8 (8-pin) or TSSOP-16 (16-pin) variants. Each package has distinct pin count, layout, and internal architecture (e.g., single-die DMP-4 vs. dual-die TSSOP-16). Board redesign is required for substitution; only DMP-4 variants share identical pinout and footprint.
