Product details
Overview
MLX90377GVS-ADB-318-RX from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit analog and PWM outputs with high-speed mode timing (≤100 µs latency), ±0.5° angular accuracy over -40°C to +160°C, and stray-field immunity for automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GVS-ADB-318-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, DMP-4 terminal mapping, ISO26262 ASIL-B safety capability for analog/PWM modes, and validated alternative options for rotary/linear position sensing in harsh environments.
Technical Context
The MLX90377GVS-ADB-318-RX implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components, enabling absolute angle or linear displacement decoding without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (4–32 points) and configurable filtering for noise rejection in EMI-prone automotive systems.
This variant operates in Standard/Legacy Mode with Analog/PWM output and High Speed Mode timing, using a 12 MHz main clock (±2.5% thermal drift) and achieving ≤100 µs latency. It features reverse polarity and overvoltage protection up to -14 V / +37 V, and built-in decoupling capacitance within the DMP-4 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM - enables dual-signal redundancy or mixed-signal interface with MCU ADC and timer capture inputs. |
| Resolution | 12-bit - delivers 0.0879° angular step resolution over 360° full scale for precise closed-loop control. |
| Latency | ≤100 µs (High Speed Mode) - supports real-time feedback in fast-response systems like electronic throttle control. |
| Accuracy | ±0.5° typical total error (including INL, temperature drift, and magnet misalignment) - meets ASIL-B functional safety requirements for analog output. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive locations including transmission and engine compartments. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct connection to vehicle battery with internal regulation. |
| Magnetic Immunity | Stray-field immune in Standard/Legacy Mode - maintains accuracy in presence of external DC/AC magnetic interference up to ±1 T. |
Pinout & Package
DMP-4 is a PCB-less dual-mold package with 4 terminals, optimized for compact, high-reliability mounting in space-constrained automotive sensors. It integrates decoupling capacitance and requires no external bypass capacitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to low-impedance chassis ground for EMC compliance. |
| 2 | VDD | Main supply input (4.5–18 V); includes reverse polarity and overvoltage protection circuitry. |
| 3 | OUT | Push-pull output capable of driving analog (0.5–4.5 V ratiometric) or PWM (0–100% duty cycle) signals directly into MCU inputs. |
| 4 | VSS | Second ground terminal - improves current return path symmetry and reduces ground bounce in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall front-end | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute position without rotational ambiguity. |
| Programmable transfer characteristic | Supports 4-, 8-, 16-, or 32-point piecewise-linear calibration - allows compensation for non-ideal magnet geometry and mechanical tolerances. |
| High-Speed Mode timing | ≤100 µs latency and ≤200 µs step response - suitable for real-time torque estimation and active suspension control loops. |
| Integrated protection | Reverse polarity (-14 V), overvoltage (+37 V), and ESD (HBM ±8 kV) - eliminates need for external protection components in cost-sensitive modules. |
| On-chip diagnostics | Passive broken-wire detection (VDD/VSS open) and active diagnostic output - supports ISO26262 ASIL-B fault detection coverage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GVS-ADB-318-RX | 8-bit resolution, fixed 4-point linearization, no SENT/SPC support - lower cost, reduced feature set. | Limited to non-safety-critical applications (e.g., HVAC flap control) where ±2° accuracy suffices. | Select when BOM cost reduction outweighs resolution and programmability needs. |
| MLX90393ELH-ABA-000-TU | 3-axis Hall sensor with I²C output, no integrated DSP or analog/PWM driver - requires external microcontroller processing. | Suitable for custom sensor fusion designs but lacks ASIL-B certification and failsafe diagnostics. | Choose only for prototyping or applications requiring flexible post-processing of raw Bx/By/Bz data. |
Compared with MLX90371GVS-ADB-318-RX, the MLX90377GVS-ADB-318-RX adds 4-bit resolution, full programmability, and ASIL-B compliance; versus MLX90393ELH-ABA-000-TU, it delivers turnkey analog/PWM output with integrated safety mechanisms - eliminating host MCU firmware development for basic position reporting.

FAQ
What output protocols does the MLX90377GVS-ADB-318-RX support?
The MLX90377GVS-ADB-318-RX supports analog ratiometric and PWM output modes only, configured via factory programming (ADB-318 code). It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-330 or ADB-380). The analog output scales from 0.5 V to 4.5 V over full-scale position, while PWM provides 0–100% duty cycle with 12-bit effective resolution.
Is the MLX90377GVS-ADB-318-RX pin-compatible with earlier Triaxis® sensors?
Yes, the MLX90377GVS-ADB-318-RX uses the DMP-4 package and maintains pin-to-pin compatibility with prior-generation Triaxis® devices such as MLX90363 and MLX90364 in the same footprint. Terminal assignments (VSS-VDD-OUT-VSS) and mechanical dimensions match exactly, enabling drop-in replacement without PCB redesign.
Does the MLX90377GVS-ADB-318-RX require external decoupling capacitors?
No, the MLX90377GVS-ADB-318-RX integrates decoupling capacitance within the DMP-4 package. Its VDEC functionality is embedded, eliminating the need for external ceramic capacitors typically required by SOIC-8 or TSSOP-16 variants. This simplifies layout and improves reliability in vibration-prone automotive modules.
What is the functional safety qualification status of the MLX90377GVS-ADB-318-RX?
The MLX90377GVS-ADB-318-RX is certified as an ASIL-B capable Safety Element out of Context (SEooC) per ISO26262 when used in analog or PWM output modes. It includes built-in diagnostics such as passive broken-wire detection and active diagnostic output, with documented fault handling time intervals and safety manual support from Melexis.
Can the MLX90377GVS-ADB-318-RX be reprogrammed by the end user?
No, the MLX90377GVS-ADB-318-RX is factory-programmed with fixed configuration: Standard/Legacy Mode, Analog/PWM output, and High Speed Mode timing. Output protocol and mode cannot be changed in the field - Melexis explicitly states that "the output protocols are not interchangeable by reprogramming at the end-user." Configuration is locked at wafer test and final trim.
