Product details
Overview
MLX90377GVS-ADB-300-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit ratiometric analog or PWM output with programmable linear transfer characteristic (4/8/16/32-point PWL), -40°C to 160°C operating range, and ASIL-B functional safety compliance for analog mode. It enables non-contacting rotary or linear position sensing in automotive throttle, pedal, and ride height systems.
For engineers reviewing the MLX90377GVS-ADB-300-TU datasheet, pinout, applications, or equivalent options, key selection factors include its DMP-4 footprint compatibility with legacy Triaxis® sensors, low-power analog/PWM output configuration (ADB-300), stray-field robustness in Standard/Legacy Mode, and integrated diagnostics including broken-wire detection on VDD/VSS.
Technical Context
The MLX90377GVS-ADB-300-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal processing engine, and ratiometric analog/PWM output stage. Its architecture supports real-time angular or linear position decoding from moving magnets without mechanical contact.
This variant operates in Standard/Legacy Mode with ADB-300 firmware: low-power analog/PWM output, no SENT/SPC support, and fixed 4–32-point piecewise-linear transfer function programming. It uses the DMP-4 package (PCB-less dual mold) with 4 pins and built-in decoupling capacitors, targeting space-constrained automotive modules requiring high-temperature reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated decoupling capacitors, 4-pin straight-lead configuration (STD0), RoHS-compliant, footprint compatible with prior-generation Triaxis® sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground return path for analog and digital domains; must be connected to system ground plane for EMC stability and accurate ratiometric output scaling. |
| 2 | VDD | Main power supply input (4.5–18 V); includes reverse-polarity and overvoltage protection circuitry; powers internal regulators and Hall front end. |
| 3 | OUT | Configurable analog (0.5–4.5 V) or PWM (0–100% duty cycle) output; ratiometric to VDD; supports pull-up/pull-down loads from 5 kΩ to 10 kΩ. |

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-TU | Same DMP-4 package and ADB firmware family, but configured for High Speed Mode - 2× faster update rate (2.5 kHz vs 1.25 kHz) and higher supply current (11.5 mA vs 11 mA). | Required where dynamic response dominates over power budget - e.g., high-bandwidth EPS feedback loops. | Select ADB-310 only if system demands faster sampling; ADB-300 remains optimal for low-power, cost-sensitive throttle/pedal nodes. |
| MLX90363GDC-ABA-000-SP | SOIC-8 packaged predecessor with fixed 10-bit analog output, no programmable PWL, and no ASIL-B certification - lacks diagnostic coverage and resolution. | Suitable for legacy industrial potentiometer replacement where functional safety is not mandated. | Not drop-in compatible: different package, pinout, and firmware; requires PCB redesign and recalibration - use only for brownfield upgrades with relaxed safety requirements. |
Compared with MLX90377GVS-ADB-310-TU, the MLX90377GVS-ADB-300-TU trades 2.5 kHz bandwidth for lower quiescent current and reduced thermal load; versus MLX90363GDC-ABA-000-SP, it adds ASIL-B compliance, 12-bit resolution, and field-programmable linearity - making it the sole choice for new ASIL-B automotive designs requiring DMP-4 integration.
