Product details
Overview
MLX90377GVE-ADB-510-SP from Melexis is a monolithic Triaxis® Hall-based absolute rotary position sensor IC operating from -40°C to 160°C, delivering 12-bit resolution via analog or PWM output in Rotary Stray-Field Immune Mode (High Field variant), with integrated DSP signal conditioning and SAE J2716 APR2016 SENT compliance. It enables non-contacting throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GVE-ADB-510-SP datasheet, pinout, applications, or equivalent options, key selection criteria include stray-field immunity for high-noise under-hood environments, programmable linear transfer characteristic (up to 32-point PWL), ISO26262 ASIL-C capability for SENT/PWM outputs, and SMP-3 package suitability for space-constrained PCB-less mounting.
Technical Context
The MLX90377GVE-ADB-510-SP implements Triaxis® technology to measure all three orthogonal magnetic field components (Bx, By, Bz), enabling robust angular position decoding up to 360° without mechanical contact. Its on-chip DSP supports real-time piecewise-linearization and configurable filtering to suppress mechanical vibration artifacts.
This variant operates exclusively in Rotary Stray-Field Immune Mode (High Field variant, -5xx code), configured for Analog/PWM output in High Speed Mode (-510 option), with fixed 12-bit resolution and factory-trimmed main clock (12–24 MHz) exhibiting ±3.5% total drift over temperature and lifetime.

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-SP | Standard/Legacy Mode (not stray-field immune); same SMP-3 package and PWM output | Lacks rotary high-field immunity; suitable only for low-interference locations like instrument clusters | Select when cost optimization outweighs under-hood EMI resilience requirements |
| MLX90377GDC-ADB-510-RE | SOIC-8 package instead of SMP-3; identical -510 functionality and specs | Requires PCB mounting and external decoupling; larger footprint but easier rework and probing | Choose for prototyping or applications needing standard through-hole-compatible layout |
Compared with MLX90377GVE-ADB-510-SP, the -310 variant trades stray-field immunity for lower cost in benign environments, while the -DC-510 offers identical sensing performance in a conventional SOIC-8 package-enabling design reuse where PCB space permits and direct magnet coupling is less critical.

FAQ
What output protocols does the MLX90377GVE-ADB-510-SP support?
The MLX90377GVE-ADB-510-SP supports analog ratiometric voltage and PWM output modes only. It is configured in Rotary Stray-Field Immune Mode (High Field variant) with High Speed Mode enabled per its -510 option code. SENT and SPC protocols are not available on this specific variant, as output mode is fixed at factory and not user-reprogrammable.
Is the MLX90377GVE-ADB-510-SP ISO26262 certified?
Yes, the MLX90377GVE-ADB-510-SP is ISO26262 ASIL-C capable for PWM output and ASIL-B capable for analog output, classified as a Safety Element out of Context (SEooC). This certification applies specifically to the -510 configuration and requires proper integration per Melexis' safety manual to achieve full ASIL-C compliance in end systems.
What package type is used by the MLX90377GVE-ADB-510-SP?
The MLX90377GVE-ADB-510-SP uses the SMP-3 package: a PCB-less single-mold surface-mount device with three solderable terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST). It is designed for direct integration onto metal housings or flex circuits in rotary position sensing assemblies.
Can the MLX90377GVE-ADB-510-SP be reprogrammed for different output modes?
No, the MLX90377GVE-ADB-510-SP output mode is permanently configured at manufacture and cannot be changed in the field. The -510 option code fixes it to Analog/PWM output in Rotary Stray-Field Immune Mode (High Field variant) and High Speed Mode. Reprogramming is not supported; alternative variants must be ordered for SENT or SPC output.
What is the maximum magnetic field tolerance of the MLX90377GVE-ADB-510-SP?
The MLX90377GVE-ADB-510-SP is rated for ±1 T magnetic flux density per its Rotary Stray-Field Immune Mode (High Field variant) specification. This enables reliable operation in high-interference environments such as near electric power steering motors or starter generators, where stray fields exceed 0.5 T.
