Product details
Overview
MLX90377GVS-ADB-310-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit resolution analog/PWM output with high-speed mode timing (≤100 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and SAE J2716 APR2016 SENT protocol support. It serves as a non-contacting rotary or linear position transducer in automotive throttle and pedal sensing systems.
For engineers reviewing the MLX90377GVS-ADB-310-RX datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, validated pin definitions for DMP-4, real-world functional safety classification (ASIL-C capable in PWM/SENT modes), and precise output timing behavior under high-speed operation.
Technical Context
The MLX90377GVS-ADB-310-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling absolute angle decoding from 0–360° or linear displacement without mechanical contact. Its on-chip DSP performs real-time signal conditioning, programmable piecewise-linearization (up to 32 segments), and stray-field immunity via dedicated magnetic configuration firmware.
This variant operates in Standard/Legacy Mode with Analog/PWM output in High Speed Mode (ADB-310), featuring 12-bit resolution, ≤100 µs latency, and ASIL-C compliance per ISO 26262 for PWM and SENT outputs. It uses the DMP-4 package (PCB-less dual mold) with built-in decoupling capacitors and supports reverse polarity and overvoltage protection up to ±18 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit (4096 steps), enabling sub-degree angular precision in throttle position feedback loops. |
| Latency (High Speed Mode) | ≤100 µs average, critical for closed-loop engine control where real-time response prevents torque lag. |
| Operating Temperature | -40°C to +160°C, qualified for under-hood automotive placement without external thermal shielding. |
| Supply Voltage Range | 4.5 V to 18 V, compatible with both regulated 5 V supplies and direct vehicle battery connection. |
| Accuracy (Angular) | ±0.5° typical over full temperature range, meeting ASIL-C diagnostic requirements for pedal position sensing. |
| Functional Safety | ISO 26262 ASIL-C capable for PWM and SENT outputs; ASIL-B for analog output - certified Safety Element out of Context. |
| Magnetic Immunity | Stray-field robustness achieved via internal IMC and configurable magnetic front-end calibration, eliminating need for external shielding. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated decoupling capacitors, 4-pin surface-mount footprint, straight leads (STD0 configuration), RoHS-compliant, designed for high-volume automated assembly and harsh-environment reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be low-impedance connection to minimize noise coupling. |
| 2 | VDD | Primary power supply input (4.5–18 V); includes reverse polarity and overvoltage protection circuitry. |
| 3 | OUT | Configurable output terminal supporting ratiometric analog (0.5–4.5 V) or PWM (100–1000 Hz) signals; push-pull driver with 27–130 Ω Ron. |
| 4 | VSS | Dedicated ground return path for output stage; dual VSS pins reduce ground bounce in high-speed PWM switching. |
Key Features

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 |
|---|---|---|---|
| MLX90371GVS-ADB-310-RX | Legacy Triaxis® generation; 10-bit resolution, higher latency (≥200 µs), no ASIL-C certification. | Limited to ASIL-B systems; insufficient for new throttle-by-wire designs requiring ASIL-C compliance. | Select only for cost-sensitive legacy redesigns where 12-bit resolution and ASIL-C are not mandated. |
| AMS AS5055A-BQFT | 14-bit resolution, SPI interface only, no native PWM/SENT output; requires external MCU for protocol translation. | Requires additional microcontroller resources and PCB space; lacks integrated diagnostics for functional safety. | Prefer when high-resolution SPI position data is needed alongside other sensor fusion tasks, not for direct ECU interface. |
Compared with MLX90377GVS-ADB-310-RX, the MLX90371 offers lower performance and safety grade but lower unit cost, while the AS5055A provides higher resolution at the expense of added system complexity and no embedded functional safety mechanisms.

FAQ
What output protocols does the MLX90377GVS-ADB-310-RX support?
The MLX90377GVS-ADB-310-RX supports analog ratiometric and PWM output modes only, configured in High Speed Mode per its ADB-310 option code. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-330 or ADB-380). The output mode is factory-programmed and cannot be changed in the field.
Is the MLX90377GVS-ADB-310-RX pin-compatible with earlier Triaxis® sensors in DMP-4 package?
Yes, the MLX90377GVS-ADB-310-RX maintains pin-to-pin compatibility with prior-generation Triaxis® sensors in DMP-4 package, including MLX90363 and MLX90371 variants. Its 4-pin layout (VSS-VDD-OUT-VSS) and straight-lead STD0 configuration allow drop-in replacement without PCB redesign.
Does the MLX90377GVS-ADB-310-RX require external decoupling capacitors?
No, the MLX90377GVS-ADB-310-RX in DMP-4 package integrates decoupling capacitors internally. This eliminates the need for external bulk capacitance, simplifying layout, reducing component count, and enhancing EMC performance in space-constrained automotive modules.
What is the functional safety qualification status of the MLX90377GVS-ADB-310-RX?
The MLX90377GVS-ADB-310-RX is ISO 26262 ASIL-C capable for PWM and SENT output modes, and ASIL-B capable for analog output mode, certified as a Safety Element out of Context (SEooC). Its hardware diagnostics include memory ECC, watchdog timers, and signal integrity monitoring with fault handling time interval < 10 ms.
Can the MLX90377GVS-ADB-310-RX operate directly from a 12 V vehicle battery?
Yes, the MLX90377GVS-ADB-310-RX supports 6–18 V supply voltage in battery mode, making it suitable for direct connection to automotive 12 V systems. Its integrated reverse polarity and overvoltage protection withstands -14 V reverse bias and +37 V transients, complying with ISO 7637-2 pulse 5a requirements.
