Product details
Overview
MLX90377GVS-ADB-308-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for non-contact rotary or linear sensing. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode with Low Power operation, supports -40°C to 160°C ambient, and uses DMP-4 package with built-in decoupling capacitors. It is deployed in automotive throttle and pedal position sensing where stray-field immunity and ASIL-B functional safety compliance are required.
For engineers reviewing the MLX90377GVS-ADB-308-RX datasheet, pinout, applications, or equivalent options, key selection considerations include its DMP-4 footprint compatibility with prior Triaxis® generations, programmable linear transfer characteristic (4/8/16/32-point PWL), SENT/SPC/PWM/analog output mode exclusivity per order code, and SAE J2716 APR2016 SENT protocol support.
Technical Context
The MLX90377GVS-ADB-308-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear displacement decoding via external magnet motion. Its on-chip DSP performs real-time signal conditioning including programmable piecewise-linearization and filtering.
It operates exclusively in Standard/Legacy Mode with analog/PWM output and Low Power configuration (ADB-308), requires no field reprogramming for protocol change, and implements ASIL-B functional safety for analog output per ISO 26262 as a Safety Element out of Context - distinct from its ASIL-C capability in SENT/PWM/SPC modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only; ADB-308 fixes low-power analog/PWM - no SENT/SPC reconfiguration possible |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling ±0.1° angular accuracy in typical configurations |
| Operating Temp | -40°C to +160°C ambient, validated across full range with supply voltage 4.5–5.5 V (regulated) or 6–18 V (battery) |
| Supply Current | 8–11.5 mA typical in Legacy Mode (-30x codes), optimized for low-power automotive subsystems |
| Functional Safety | ISO 26262 ASIL-B capable for analog output mode; Safety Element out of Context architecture confirmed |
| Magnetic Sensing | Triaxis® 3-axis Hall front end with integrated IMC; enables robust absolute position sensing without mechanical wear |
| Package | DMP-4 (dual-mold, PCB-less) with 4 terminals: VSS, VDD, OUT, VSS - pin-to-pin compatible with legacy Triaxis® DMP-4 devices |
Pinout & Package
DMP-4 package: compact, PCB-less dual-mold construction with built-in decoupling capacitors; designed for direct soldering onto flex or rigid boards with minimal external components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to system ground with low-impedance path |
| 2 | VDD | Main supply input (4.5–18 V); accepts regulated or battery-supplied rails; internal regulator stabilizes core logic |
| 3 | OUT | Push-pull output terminal delivering ratiometric analog voltage (0.5–4.5 V) or PWM signal (10–90% duty cycle) |
| 4 | VSS | Second ground terminal; improves thermal dissipation and reduces ground loop impedance in high-noise environments |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute position decoding from single moving magnet - eliminates need for multi-die or complex magnet assemblies |
| Programmable Transfer Curve | Supports 4-, 8-, 16-, or 32-point piecewise-linear (PWL) calibration to correct for mechanical nonlinearity or magnet field distortion in final assembly |
| DMP-4 Integrated Decoupling | Built-in capacitors eliminate requirement for external VDD/VDEC bypass components - reduces BOM count and layout area by ~30% vs SOIC-8 implementation |
| Stray-Field Immunity | Standard/Legacy Mode (-3xx) provides inherent robustness against external magnetic interference without requiring shielded housings or active compensation |
| ASIL-B Functional Safety | Validated fault handling time interval and diagnostic coverage for analog output path - enables integration into ASIL-B automotive subsystems without additional hardware redundancy |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-RX | Same DMP-4 package and Legacy Mode, but High Speed analog/PWM configuration (11.5 mA vs 10 mA, faster startup) | Required where >10 kHz sampling or sub-50 µs latency is critical; not suitable for ultra-low-power sleep-mode subsystems | Select ADB-310-RX only if timing budget demands higher update rate; ADB-308-RX preferred for energy-constrained modules |
| MLX90371GVS-ADB-308-RX | Legacy Triaxis® generation; same DMP-4 footprint and ADB-308 coding, but 10-bit resolution and no ASIL-B certification | Limited to non-safety-critical industrial or aftermarket applications; lacks ISO 26262 documentation and diagnostic coverage | Use MLX90371GVS-ADB-308-RX only for cost-sensitive legacy designs where ASIL-B is not mandated |
Compared with MLX90377GVS-ADB-308-RX, the ADB-310-RX variant trades lower quiescent current for higher speed, while the MLX90371GVS-ADB-308-RX offers footprint compatibility at the expense of resolution and functional safety validation - making the original MLX90377GVS-ADB-308-RX optimal for new ASIL-B automotive designs requiring lowest power and certified robustness.

FAQ
What output protocols does the MLX90377GVS-ADB-308-RX support?
The MLX90377GVS-ADB-308-RX supports only analog ratiometric and PWM output modes, as fixed by its ADB-308 option code. SENT and SPC protocols are physically unavailable on this variant - they require different order codes (e.g., ADB-330 or ADB-380) and cannot be enabled via programming or firmware update.
Is the MLX90377GVS-ADB-308-RX pin-compatible with earlier Triaxis® DMP-4 sensors?
Yes, the MLX90377GVS-ADB-308-RX uses the DMP-4 package with identical 4-terminal pinout (VSS-VDD-OUT-VSS) and mechanical dimensions as prior-generation Melexis Triaxis® DMP-4 devices, enabling drop-in replacement in existing layouts without PCB revision.
Does the MLX90377GVS-ADB-308-RX require external decoupling capacitors?
No, the MLX90377GVS-ADB-308-RX integrates decoupling capacitors within the DMP-4 package, eliminating the need for external VDD bypass components. This reduces bill-of-materials count and simplifies layout versus SOIC-8 or TSSOP-16 variants that require discrete VDEC connections.
What functional safety level is certified for the MLX90377GVS-ADB-308-RX analog output?
The MLX90377GVS-ADB-308-RX is ISO 26262 ASIL-B capable for its analog output mode, documented as a Safety Element out of Context. This certification covers fault detection, diagnostic coverage, and fault handling time interval - verified for use in ASIL-B automotive subsystems such as throttle and pedal position sensing.
Can the MLX90377GVS-ADB-308-RX be reprogrammed to change its output mode after manufacturing?
No, the MLX90377GVS-ADB-308-RX output mode is permanently fixed at wafer-level programming per its ADB-308 option code. Analog/PWM Low Power configuration cannot be altered in the field - alternate protocols require ordering the corresponding part number (e.g., ADB-330 for SENT).
