Product details
Overview
MLX90422GVS-ADD-038-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, ISO26262 ASIL B safety element out of context, and operation from −40°C to +160°C in DMP-4 package. It delivers robust non-contacting angular measurement up to 360° in automotive throttle and pedal systems.
For engineers reviewing the MLX90422GVS-ADD-038-SP datasheet, pinout, applications, or equivalent options, key selection factors include SENT frame timing (861–905 µs), 1.32–2.03 ms average latency, ±0.5° typical angular accuracy, dual-mold DMP-4 package with 4-pin configuration, and programmable diagnostics for broken-wire detection.
Technical Context
The MLX90422GVS-ADD-038-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an analog-to-digital signal conditioner, and a DSP enabling absolute angle calculation via user-defined axis selection. Its SENT output supports Single Secure Sensor A.3 (H.4) format with embedded error codes and user-defined values.
It operates in continuous synchronous acquisition mode by default, with fixed 3 µs tick time, 287-tick frame length, and two angle acquisitions per frame. Programmable filtering (Filter 0/1/2) and configurable diagnostics-including passive broken-wire detection at 99.5% VDD for VSS open-support functional safety compliance in ASIL B systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GVS-ADD-038-SP | Single-die SENT position sensor with identical DMP-4 package and pinout but no ASIL B safety certification | Lacks ISO26262 ASIL B SEooC documentation and diagnostic coverage features required for safety-critical throttle/pedal systems | Select when functional safety certification is not mandated and cost optimization is prioritized |
| AMS30450-B01 | SENT-output Hall-based rotary sensor with 12-bit resolution, 4.5–5.5 V supply, and −40°C to +150°C rating; no Triaxis® 3D field sensing | Relies on external flux concentrators for Z-field sensitivity; limited to 2D angular measurement without Bz compensation | Choose for simpler 2-axis applications where magnetic design constraints prevent full Triaxis® deployment |
Compared with MLX90422GVS-ADD-038-SP, MLX90421GVS-ADD-038-SP omits ASIL B safety mechanisms and diagnostic cycles, while AMS30450-B01 lacks true 3D field vector processing-making MLX90422GVS-ADD-038-SP uniquely suited for high-accuracy, safety-compliant absolute position sensing in constrained magnetic geometries.

FAQ
What is the operating temperature range of the MLX90422GVS-ADD-038-SP?
The MLX90422GVS-ADD-038-SP operates from −40°C to +160°C ambient temperature. Its DMP-4 package supports short-term exposure up to +180°C for ≤250 hours, with degraded performance per Table 10 in the datasheet. Junction temperature must remain ≤+175°C under normal conditions.
Does the MLX90422GVS-ADD-038-SP require external decoupling capacitors?
No. The MLX90422GVS-ADD-038-SP in DMP-4 package integrates built-in decoupling capacitance, eliminating the need for external VDEC capacitors. Pin 1 and Pin 4 are both VSS terminals, and the internal regulator stabilizes the 3.3 V analog rail directly from VDD.
How does the SENT output of the MLX90422GVS-ADD-038-SP differ from standard PWM interfaces?
The MLX90422GVS-ADD-038-SP uses SENT (SAE J2716 APR2016) with fixed 3 µs tick time, A.3 (H.4) frame format, and embedded diagnostics-not PWM. It transmits 12-bit angle data plus CRC, status flags, and error codes in each 287-tick frame, enabling deterministic timing and fault detection unattainable with analog PWM.
Can the MLX90422GVS-ADD-038-SP be programmed for linear position sensing?
Yes. The MLX90422GVS-ADD-038-SP supports both angular rotary and linear position modes via factory or end-user programming. Its Triaxis® architecture allows selection of Bx/By, Bx/Bz, or By/Bz axes to compute position from magnet translation, with programmable transfer characteristics calibrated for stroke lengths up to 100 mm.
What safety certifications apply to the MLX90422GVS-ADD-038-SP?
The MLX90422GVS-ADD-038-SP is certified as an ISO26262 ASIL B Safety Element out of Context (SEooC) and AEC-Q100 Grade 0 qualified. It includes hardware-level diagnostics-such as broken-wire detection, watchdog timers, and memory ECC-that satisfy ASIL B random and systematic fault coverage requirements without additional external safety monitors.
