Product details
Overview
MLX90377GVS-ADB-330-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC designed for absolute rotary or linear position sensing in harsh automotive environments. It delivers 12-bit SENT output with 3 μs tick time, operates from -40°C to 160°C, supports SAE J2716 APR2016 compliance, and features ASIL-C functional safety capability for SENT mode. It is used in throttle, pedal, and steering wheel position sensing where high immunity to stray fields and robust serial communication are required.
For engineers reviewing the MLX90377GVS-ADB-330-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance, DMP-4 package compatibility, -40°C to +160°C operating range, ASIL-C safety qualification, and stray-field immune operation in Standard/Legacy Mode.
Technical Context
The MLX90377GVS-ADB-330-SP implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to compute absolute angular or linear position without mechanical contact. Its on-chip DSP performs real-time signal conditioning, including programmable piecewise-linear transfer functions (up to 32 segments) and configurable filtering.
This variant is factory-configured for SENT output only (ADB-330), uses the DMP-4 package (PCB-less dual-mold), and operates in Standard/Legacy Mode - not Stray-Field Immune - with 3 μs tick time, SAE J2716 APR2016 conformance, and ASIL-C capability per ISO 26262 as a Safety Element out of Context.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-SP | Same DMP-4 package and temperature grade, but configured for PWM output (not SENT); no SAE J2716 support; ASIL-B only. | Used where ECU lacks SENT receiver but accepts PWM duty-cycle signals; lower diagnostic depth than SENT. | Select only if legacy ECU interface mandates PWM and ASIL-C is not required. |
| MLX90371GVS-ADB-330-SP | Legacy Triaxis® generation; same DMP-4 package and SENT-3μs configuration, but fixed 10-bit resolution and no programmable PWL. | Suitable for cost-sensitive applications with relaxed accuracy needs (<±1.5°) and no field calibration requirement. | Choose when system does not require 12-bit resolution or in-system transfer function tuning. |
Compared with MLX90377GVS-ADB-330-SP, the ADB-310 variant trades SENT protocol and ASIL-C certification for PWM simplicity, while the MLX90371 offers identical mechanical fit and SENT timing but reduced resolution and fixed signal processing - making the MLX90377GVS-ADB-330-SP optimal for new ASIL-C designs demanding maximum flexibility and precision.

FAQ
What output protocol does the MLX90377GVS-ADB-330-SP support?
The MLX90377GVS-ADB-330-SP is factory-configured exclusively for SENT output with 3 μs tick time and full SAE J2716 APR2016 compliance. It does not support analog, PWM, or SPC modes - those require different option codes (e.g., ADB-300 or ADB-310). The SENT frame includes position data, status nibble, CRC, and diagnostic flags, all generated internally by the MLX90377GVS-ADB-330-SP.
Is the MLX90377GVS-ADB-330-SP qualified for ASIL-C applications?
Yes, the MLX90377GVS-ADB-330-SP is ISO 26262 ASIL-C capable for its SENT output mode as a Safety Element out of Context (SEooC). This qualification covers integrated diagnostics such as memory ECC, watchdog timers, and signal path monitoring - all implemented within the MLX90377GVS-ADB-330-SP silicon. ASIL-B applies only to analog output variants, which this part does not support.
What package type is used by the MLX90377GVS-ADB-330-SP?
The MLX90377GVS-ADB-330-SP uses the DMP-4 (Dual Mold Package), a PCB-less 4-terminal surface-mount package with pins 1 (VSS), 2 (VDD), 3 (OUT), and 4 (VSS). It is mechanically and electrically pin-compatible with earlier Triaxis® DMP-4 sensors, enabling drop-in replacement in existing layouts without redesign.
Can the MLX90377GVS-ADB-330-SP be reprogrammed to change its output mode?
No, the MLX90377GVS-ADB-330-SP is factory-programmed for SENT output only, and output protocols are not interchangeable via end-user programming. The ADB-330 option code permanently configures the MLX90377GVS-ADB-330-SP firmware and hardware resources for SENT - attempting to force other protocols will result in undefined behavior or failure to initialize.
What is the operating temperature range of the MLX90377GVS-ADB-330-SP?
The MLX90377GVS-ADB-330-SP is rated for continuous operation from -40°C to +160°C ambient temperature, validated across its full electrical specification range. This extended grade supports placement in high-heat zones such as engine compartments, transmission housings, and brake actuator assemblies - a key specification confirmed for the MLX90377GVS-ADB-330-SP in Melexis' official datasheet revision 003.
