Product details
Overview
MLX90377GVS-ADB-308-RE from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode, operates from -40°C to 160°C, supports stray-field robust operation, and targets automotive pedal/throttle/steering position sensing.
For engineers reviewing the MLX90377GVS-ADB-308-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (DMP-4), confirmed output protocol (analog/PWM, low-power mode), ISO26262 ASIL-B capability for analog output, and validated alternative options for position-sensing system design.
Technical Context
The MLX90377GVS-ADB-308-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, an ADC, DSP for advanced signal processing, and dual-output stage supporting ratiometric analog and PWM. Its DMP-4 package embeds decoupling capacitors and uses straight leads (STD0 configuration).
This variant implements Standard/Legacy Mode (-3xx option code) with programmable linear transfer characteristic (4- or 8-point piecewise-linear), selectable fast SENT/PWM/SPC/analog output, and built-in diagnostics including broken-wire detection on VDD and VSS. It is not configured for SENT or SPC per ADB-308 coding.

| Package | DMP-4 (PCB-less dual mold), 4-pin, STD0 straight lead form, RoHS-compliant |
Pinout & Package
DMP-4 is a compact, PCB-less dual-mold package with integrated decoupling capacitors, designed for direct soldering onto flex or rigid PCBs. It features 4 terminals in a 2.54 mm pitch, compatible with legacy Triaxis® footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be low-impedance connection |
| 2 | VDD | Main supply input (4.5–18 V); internal regulator powers core logic and analog blocks |
| 3 | OUT | Push-pull output supporting ratiometric analog voltage (0.5–4.5 V) and PWM (10–90% duty cycle) |
| 4 | VSS | Second ground terminal - improves EMC performance and current return path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true absolute angle/linear position without mechanical cams or gears |
| Programmable Transfer Curve | Configurable 4- or 8-point piecewise-linear mapping allows precise calibration to mechanical travel profiles |
| Stray-Field Immunity | Standard/Legacy Mode (-3xx) provides inherent robustness against external magnetic interference up to ±1 T |
| Integrated Diagnostics | Built-in broken-wire detection on VDD/VSS and active diagnostic reporting via output pin state |
| DMP-4 Embedded Capacitors | On-package decoupling eliminates need for external VDD/VSS bypass capacitors, reducing BOM count and layout area |
Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
Use Scenario: Monitoring accelerator or brake pedal angular displacement in ICE and hybrid powertrains. IC Role / Device Role / Timing Role: Absolute rotary position transducer delivering real-time analog voltage and PWM signals synchronized to ECU sampling clocks.

Use Value: Programmable 4-point PWL transfer curve matches nonlinear spring characteristics, improving height regulation precision by >30% vs fixed-gain sensors. |
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 |
|---|---|---|---|
| MLX90377GVS-ADB-310-RE | Same DMP-4 package and analog/PWM outputs, but configured for High Speed Mode (faster update rate, higher IDD) | Preferred for dynamic applications requiring <5 ms latency (e.g., active suspension feedback) | Select ADB-310 if system demands faster response; ADB-308 optimizes for lower power consumption in static/low-dynamic use cases |
| MLX90371GVS-ADB-300-RE | Legacy Triaxis® generation; 10-bit resolution, no DSP-based linearization, no ASIL-B certification | Suitable for cost-sensitive non-safety-critical industrial position sensing only | Choose MLX90371 only for legacy redesigns where 12-bit accuracy, programmable PWL, and ISO26262 compliance are not required |
Compared with MLX90377GVS-ADB-308-RE, the ADB-310 variant trades 2 mA higher quiescent current for sub-5 ms latency, while the MLX90371 offers footprint compatibility at reduced resolution and absent safety qualification - making ADB-308 the optimal balance of power efficiency, accuracy, and functional safety for new automotive designs.

FAQ
What output protocols does the MLX90377GVS-ADB-308-RE support?
The MLX90377GVS-ADB-308-RE supports only ratiometric analog voltage and PWM outputs. Its ADB-308 option code explicitly configures it for Standard/Legacy Mode with low-power analog/PWM operation - SENT and SPC protocols are disabled and cannot be enabled via programming. This is fixed at factory trim.
Is the MLX90377GVS-ADB-308-RE certified for automotive functional safety standards?
Yes, the MLX90377GVS-ADB-308-RE is ISO26262 ASIL-B capable for its analog output mode as a Safety Element out of Context (SEooC). This certification covers diagnostic coverage, fault handling time intervals, and systematic capability - documented in Melexis' official safety manual for the MLX90377 family.
What is the package type and pin configuration of the MLX90377GVS-ADB-308-RE?
The MLX90377GVS-ADB-308-RE uses the DMP-4 package: a PCB-less dual-mold construction with four terminals (VSS, VDD, OUT, VSS) in 2.54 mm pitch and STD0 straight leads. It integrates decoupling capacitors, eliminating external bypass components and simplifying layout for space-constrained automotive modules.
Can the MLX90377GVS-ADB-308-RE be reprogrammed to change its output mode or transfer function?
Yes - the MLX90377GVS-ADB-308-RE supports end-user programming of its transfer characteristic (4- or 8-point PWL), filtering, diagnostics, and output parameters via I²C-compatible interface using Melexis' PTC connector. However, the base output protocol (analog/PWM) and mode (Standard/Legacy) are permanently set by the ADB-308 option code and cannot be altered post-manufacture.
What magnetic configurations are supported by the MLX90377GVS-ADB-308-RE?
The MLX90377GVS-ADB-308-RE operates in Standard/Legacy Mode (-3xx), supporting both absolute rotary (0–360°) and linear position sensing using off-axis or side-shaft magnet arrangements. It does not implement stray-field immune modes (which require -1xx, -2xx, or -5xx option codes) but retains inherent robustness against fields up to ±1 T.
