Product details
Overview
MLX90377GVE-ADB-310-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contact sensing. It delivers 12-bit resolution analog/PWM output in High Speed Mode, operates from -40°C to 160°C, supports stray-field immune magnetic configurations, and is packaged in SMP-3 (PCB-less single mold). It serves as the core sensing element in automotive throttle and pedal position systems.
For engineers reviewing the MLX90377GVE-ADB-310-TU datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, SMP-3 package terminal mapping, ISO26262 ASIL-B safety capability for analog mode, and validated alternative options for position-sensing designs requiring high-temperature operation and programmable transfer characteristics.
Technical Context
The MLX90377GVE-ADB-310-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear position decoding with a single moving magnet. Its on-chip DSP performs real-time signal conditioning, including 4- or 8-point piecewise-linearization and configurable filtering.
This variant uses the SMP-3 package (3-terminal, PCB-less), operates in Standard/Legacy Mode with Analog/PWM output in High Speed configuration (−310 option code), and features SAE J2716 APR2016 SENT compatibility, 48-bit ID, and ISO26262 ASIL-B qualification for analog output mode as a Safety Element out of Context.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit effective resolution for analog and PWM outputs, enabling ±0.1° angular accuracy in typical rotary configurations. |
| Operating Temperature | −40°C to +160°C junction range, supporting under-hood automotive placement without external thermal derating. |
| Supply Voltage Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery), with reverse voltage protection to −14 V. |
| Output Modes | Analog ratiometric and PWM only (High Speed Mode); no SENT/SPC enabled per ADB-310 option code. |
| Startup Time | ≤ 5 ms in analog mode - time from VDD crossing 4.1 V to first valid output - critical for fast-response pedal sensing. |
| Magnetic Immunity | Stray-field immune configuration not active; uses Standard/Legacy Mode (−3xx), optimized for controlled magnetic circuits. |
| Functional Safety | ISO26262 ASIL-B capable for analog output mode as Safety Element out of Context (SEooC), with diagnostic coverage for internal faults. |
Pinout & Package
SMP-3 package: 3-terminal, PCB-less single-mold construction with integrated decoupling capacitance, designed for direct soldering onto flex or rigid substrates with minimal footprint (2.1 mm × 1.6 mm × 0.55 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VDD) | Primary power supply input | Accepts 4.5–18 V; internal regulator powers analog/digital blocks; reverse polarity protected to −14 V. |
| 2 (OUT) | Configurable analog/PWM output driver | Delivers ratiometric voltage (0.5–4.5 V) or PWM (10–90% duty cycle) with push-pull drive; supports 5–10 kΩ load. |
| 3 (VSS) | Ground reference | Common return for supply and signal; must be low-impedance to ensure <±0.5% analog accuracy and EMC robustness. |
| a (INPUT) | Factory test interface | Not user-accessible in final application; used during wafer sort and calibration; left floating or grounded per design. |
| b (TEST) | Factory test interface | Reserved for Melexis internal diagnostics; no functional role in end-user circuit; must not be connected externally. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute position without mechanical commutation. |
| Programmable Transfer Curve | Supports 4- or 8-point piecewise-linear (PWL) calibration to correct for magnet nonlinearity and mechanical tolerances in production. |
| High-Speed Analog/PWM Output | Optimized timing for ≤5 ms startup and <100 µs latency - suitable for closed-loop control loops in throttle actuation. |
| Integrated Signal Processing | DSP-based filtering, temperature compensation, and diagnostics reduce host MCU computational load and enable self-test capability. |
| Robust Packaging | SMP-3's molded construction eliminates PCB interconnects, improving vibration resistance and reducing assembly cost in space-constrained modules. |

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 |
|---|---|---|---|
| MLX90371GSE-ADB-310-SP | SOIC-8 package, identical ADB-310 functionality (Analog/PWM High Speed), same temperature grade (G), but lacks 48-bit ID and enhanced diagnostics. | Requires PCB footprint change; suitable for legacy board reuse where SMP-3 mounting is impractical. | Select when SOIC-8 hand-soldering or standard reflow compatibility is prioritized over size and weight reduction. |
| TLV493DW2B6A1HALA1 | 3D Hall sensor (Infineon), 12-bit I²C output only, no analog/PWM, −40°C to 125°C rating, smaller TSSOP-6 package. | Limited to digital bus interfaces; insufficient temperature range for under-hood throttle use; requires external ADC or MCU polling. | Choose only for non-safety-critical, lower-temperature linear/rotary sensing where I²C integration simplifies system architecture. |
Compared with MLX90377GVE-ADB-310-TU, the MLX90371GSE-ADB-310-SP offers identical signal chain performance in a larger, more manufacturable package, while the TLV493DW2B6A1HALA1 trades analog/PWM immediacy and ASIL-B compliance for compactness and digital flexibility - making the MLX90377GVE-ADB-310-TU optimal for high-temperature, safety-aware analog-critical applications.
