Product details
Overview
MLX90377GVE-ADB-210-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for linear stray-field immune applications, delivering 12-bit analog or PWM output with high-speed mode timing, ±0.5° angular accuracy over -40°C to +160°C, and integrated signal conditioning for non-contact rotary/linear sensing in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GVE-ADB-210-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), confirmed pin functions (VDD/OUT/VSS), real-world stray-field immunity performance, and validated alternative options for ASIL-B–capable position sensing designs.
Technical Context
The MLX90377GVE-ADB-210-SP implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components, enabling absolute position decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for robust operation under EMI.
This variant operates in Linear Stray-Field Immune Mode with Analog/PWM output and High Speed Mode timing, requiring no external programming post-manufacture. It features built-in reverse polarity and overvoltage protection, internal analog/digital regulators, and temperature compensation across its full operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GSE-ADB-030-SP | SOIC-8 package; legacy mode only; no stray-field immunity; 10-bit analog output. | Limited to low-interference environments; unsuitable for under-hood locations near motors or solenoids. | Select when cost sensitivity outweighs stray-field robustness and ASIL-B compliance requirements. |
| MLX90393ELQ-ABA-000-TU | 3-axis Hall sensor with I²C interface; no integrated DSP; requires external microcontroller for position calculation. | Demands host-side firmware development for linearization and diagnostics; lacks SENT/SPC output modes. | Choose for flexible multi-sensor fusion architectures where centralized processing is preferred over distributed intelligence. |
Compared with MLX90377GVE-ADB-210-SP, MLX90371GSE-ADB-030-SP offers lower system cost but forfeits stray-field resilience and functional safety certification, while MLX90393ELQ-ABA-000-TU shifts signal processing burden to the host MCU, increasing software validation scope but enabling custom algorithm deployment.

FAQ
What output protocols does the MLX90377GVE-ADB-210-SP support?
The MLX90377GVE-ADB-210-SP supports analog ratiometric voltage and PWM output modes only, configured in Linear Stray-Field Immune Mode with High Speed timing. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-230 or ADB-280). The output mode is factory-programmed and cannot be changed in the field.
Is the MLX90377GVE-ADB-210-SP pin-compatible with other MLX90377 variants in SMP-3 package?
Yes, all MLX90377 variants in SMP-3 package - including MLX90377GVE-ADB-210-SP - share identical pinout (VDD/OUT/VSS plus INPUT/TEST test pads) and mechanical footprint. However, electrical behavior differs by option code: ADB-210 enables Linear Stray-Field Immune Mode, while ADB-110 or ADB-510 configure rotary variants with distinct magnetic sensitivity profiles.
Does the MLX90377GVE-ADB-210-SP require external decoupling capacitors?
No, the MLX90377GVE-ADB-210-SP in SMP-3 package integrates internal decoupling capacitance, eliminating the need for external VDD bypass capacitors. This simplifies PCB layout and improves reliability in space-constrained automotive modules where board area is at a premium.
What is the maximum magnetic field the MLX90377GVE-ADB-210-SP can withstand without damage?
The MLX90377GVE-ADB-210-SP has an absolute maximum magnetic flux density rating of ±1 T (±10,000 G), per Table 8 of the datasheet. Operation within its specified linear range (±100 mT for Linear Stray-Field Immune Mode) ensures accuracy; exposure beyond ±1 T may cause permanent parametric shift or latch-up.
How is functional safety implemented in the MLX90377GVE-ADB-210-SP?
The MLX90377GVE-ADB-210-SP achieves ASIL-B capability for analog output mode as a Safety Element out of Context (SEooC), with built-in diagnostics including broken-wire detection on VDD/VSS, supply monitoring, output short-circuit reporting, and internal clock/watchdog supervision - all documented in the ISO 26262 safety manual (Rev. 003, Section 15).
