Technical Context
The MLX90422GDC-ADD-030-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a DSP performing on-chip absolute angle calculation, and a SENT output stage compliant with SAE J2716 APR2016. It supports both continuous synchronous and asynchronous acquisition modes.
Its SOIC-8 variant uses single-die architecture with VDD, VSS, OUT, and VDEC pins; startup time is 5.93 ms to first valid angle; latency ranges from 1.32–2.03 ms depending on filter configuration; and it operates with fixed 3 μs SENT tick time and 861–905 μs frame period in default synchronous mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90421GDC-ADD-030-TU | Single-die SENT sensor with identical SOIC-8 package and pinout but limited to 12-point linearization and no ASIL B certification. | Targeted at non-safety-critical industrial position sensing; lacks ISO26262 documentation and diagnostic coverage. | Select when ASIL B compliance and 17-point calibration are not required to reduce BOM cost. |
| AMS AS5600-LSOT | I²C-output 12-bit angle sensor with integrated magnet; no SENT interface, no AEC-Q100 qualification, max operating temp +85°C. | Suitable for consumer or light-industrial encoders; cannot replace MLX90422GDC-ADD-030-TU in automotive powertrain or chassis systems. | Choose only for cost-sensitive, non-automotive designs where SENT protocol and high-temp operation are unnecessary. |
Compared with MLX90421GDC-ADD-030-TU, the MLX90422GDC-ADD-030-TU adds ASIL B certification, 17-point linearization, and enhanced diagnostics-justifying its use in safety-critical throttle/pedal systems. Against AMS AS5600-LSOT, it offers automotive-grade ruggedness, SENT compatibility, and triple-axis field resolution essential for robust magnet misalignment tolerance.

FAQ
What is the SENT frame structure used by MLX90422GDC-ADD-030-TU?
The MLX90422GDC-ADD-030-TU outputs SENT frames in A.3 (H.4) format with fixed 3 μs tick time and 287-tick frame length (861–905 μs duration). Each frame carries absolute angle data, CRC nibble, status bits, and optional diagnostics - fully compliant with SAE J2716 APR2016 revision and validated for use in automotive ECUs requiring SENT interface.
Does MLX90422GDC-ADD-030-TU support programmable magnetic field range?
Yes, MLX90422GDC-ADD-030-TU supports user-programmable magnetic field thresholds (BTH_LOW and BTH_HIGH) and sensing mode selection (X-Y, X-Z, or Y-Z) via on-chip NVRAM. This allows optimization for specific magnet strengths and orientations - critical for achieving ±0.5° accuracy in pedal or throttle assemblies with varying air gaps.
What is the maximum junction temperature rating for MLX90422GDC-ADD-030-TU?
The MLX90422GDC-ADD-030-TU has a maximum junction temperature (TJ) rating of +175°C, with SOIC-8 package thermal resistance (RθJA) enabling reliable operation at 160°C ambient. Extended high-temperature operation up to +180°C ambient is supported for ≤250 hours only in DMP-4/SMP-3/SMP-4 packages-not applicable to this SOIC-8 variant.
How does the MLX90422GDC-ADD-030-TU handle electromagnetic interference (EMI)?
The MLX90422GDC-ADD-030-TU mitigates EMI through internal test/N.C. pin grounding in application mode, mandatory VDEC decoupling (100 nF), and differential magnetic sensing that rejects common-mode field noise. Melexis recommends tying all N.C. and Test pins to PCB ground - a practice verified to improve radiated emissions margin by >6 dB in automotive EMC testing.
Can MLX90422GDC-ADD-030-TU be used in redundant safety architectures?
No - MLX90422GDC-ADD-030-TU is a single-die SOIC-8 device and does not provide hardware redundancy. For dual-die redundancy, Melexis offers MLX90422GO variants in TSSOP-16 or SMP-4 packages. However, MLX90422GDC-ADD-030-TU achieves ASIL B as a Safety Element out of Context (SEooC), meaning it can be integrated into higher-ASIL systems with appropriate system-level monitoring and fault handling.
