Product details
Overview
MLX90377GVE-ADB-300-TU 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 or PWM output in Standard/Legacy Mode, operates from -40°C to 160°C, supports stray-field immune magnetic configurations, and is qualified for automotive ASIL-B safety integrity in analog mode.
For engineers reviewing the MLX90377GVE-ADB-300-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), confirmed output behavior (analog/PWM, low-power), functional safety classification (ASIL-B), and real-world use cases including throttle and pedal position sensing.
Technical Context
The MLX90377GVE-ADB-300-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear displacement decoding with on-chip DSP and analog-to-digital signal conditioning. Its SMP-3 package embeds decoupling capacitors and uses a 3-pin configuration optimized for compact PCB-less mounting.
This variant implements Standard/Legacy Mode (-3xx option code) with programmable linear transfer characteristic (4- or 8-point piecewise-linear), selectable analog/PWM output, and low-power operation. It does not support SENT or SPC protocols - those require ADB-330 or ADB-380 variants - and lacks dual-die redundancy (TSSOP-16) or SOIC-8 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Analog ratiometric (0.5–4.5 V) and PWM (duty cycle proportional to position); no SENT/SPC support per ADB-300 option code. |
| Resolution | 12-bit effective resolution for both analog and PWM outputs, enabling ≤0.1° angular or sub-millimeter linear position accuracy. |
| 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). |

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-310-TU | Same SMP-3 package and Standard/Legacy Mode, but configured for High Speed Mode (higher update rate, 12–13.5 mA supply current). | Preferred where faster dynamic response is required (e.g., high-bandwidth EPS), not for low-power always-on use. | Select ADB-310 only if latency < 5 ms is mandatory; ADB-300 remains optimal for energy-constrained systems. |
| MLX90371GVE-ADB-300-TU | Legacy Triaxis® generation in SMP-3; supports only analog output (no PWM), lower resolution (10-bit), no ASIL-B certification. | Suitable for cost-sensitive non-safety-critical applications (e.g., HVAC dampers), not for ASIL-B automotive systems. | Choose MLX90371 only for legacy redesigns with unchanged analog interface; MLX90377GVE-ADB-300-TU adds safety compliance and dual-output flexibility. |
Compared with MLX90377GVE-ADB-310-TU, the MLX90377GVE-ADB-300-TU trades update speed for lower power consumption and thermal stability; compared with MLX90371GVE-ADB-300-TU, it adds ASIL-B qualification, 12-bit resolution, and PWM capability - making it the only option meeting modern automotive functional safety and performance requirements in SMP-3 form factor.
