Overview
MLX90377GVE-ADB-310-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contacting measurement. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to 160°C, supports ratiometric analog output with ±0.5% INL accuracy, and is qualified for automotive pedal and throttle position sensing per ISO 26262 ASIL-B.
For engineers reviewing the MLX90377GVE-ADB-310-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SMP-3 package compatibility, stray-field immune operation in Standard/Legacy mode, 12-bit analog/PWM output timing (Tstup3 ≤ 8 ms), and ASIL-B safety compliance for analog output path.
Technical Context
The MLX90377GVE-ADB-310-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal conditioning, and programmable piecewise-linear transfer characteristic (4/8/16/32 points). It uses on-chip ROM firmware and NVRAM for user configuration of output mode, range, and diagnostics.
This variant implements Standard/Legacy Mode (-3xx code) with Analog/PWM output in High Speed Mode (ADB-310), delivering 12-bit resolution at ≤8 ms startup time (Tstup3), 10 mA typical supply current, and ratiometric analog output referenced to VDD with 0.5–1.2%VDD low-side saturation and 97–99%VDD high-side saturation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVE-ADB-300-SP | Same SMP-3 package and Triaxis® core, but configured for Low Power Mode (10 mA vs. 11.5 mA) and longer startup (Tstup3 ≤ 12 ms). | Preferred for battery-powered or thermally constrained modules where update rate <1 kHz suffices. | Select ADB-300 when power budget is tighter and latency tolerance >8 ms; ADB-310 prioritizes speed over current draw. |
| MLX90377GDC-ADB-310-RE | Identical ADB-310 functionality but in SOIC-8 package (8-pin, 3.9 mm × 4.9 mm) with different pinout (VDD/VSS/OUT/N.C.) and decoupling pin (VDEC). | Used where legacy PCB layout re-use or through-hole prototyping is required; lacks SMP-3's compactness and integrated capacitors. | Choose SOIC-8 only if existing board space or assembly process mandates it; SMP-3 offers superior EMC and smaller footprint. |
Compared with MLX90377GVE-ADB-300-SP, the MLX90377GVE-ADB-310-SP trades 1.5 mA higher supply current for 4 ms faster startup and tighter timing control-critical for fast-cycling throttle actuation.
