Product details
Overview
MLX90377GDC-ADB-210-RE from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute linear or rotary position sensing. It delivers 12-bit resolution analog/PWM output in High Speed Mode, operates from -40°C to +160°C, features stray-field immunity for linear configurations, and is qualified per ISO 26262 ASIL-B for analog mode - used in automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GDC-ADB-210-RE datasheet, pinout, applications, or equivalent options, key selection factors include its SOIC-8 package, linear stray-field immune magnetic configuration, high-speed analog/PWM timing (≤1.5 ms latency), and ASIL-B safety capability in ratiometric output mode.
Technical Context
The MLX90377GDC-ADB-210-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, enabling robust decoding of magnet position without mechanical contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable filtering for noise rejection in harsh EMI environments.
This variant uses the Linear Stray-Field Immune Mode (-2xx option code), optimized for linear displacement measurement under external magnetic interference. It implements High Speed Mode (option digit '1') with 12-bit analog/PWM output, achieving ≤1.5 ms latency and startup time < 5 ms - critical for real-time closed-loop control in automotive powertrain systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-210-RE | TSSOP-16 dual-die package with isolation between dies; higher pin count; supports full redundancy | Required for ASIL-C systems needing dual-channel independent outputs; not pin-compatible with SOIC-8 | Select when functional safety requires hardware redundancy and isolated signal paths |
| MLX90371GDC-ADB-010-RE | Legacy Triaxis® device; 10-bit resolution; fixed linear transfer; no SENT/SPC; lower temp range (-40°C to +150°C) | Cost-sensitive industrial linear sensing where ASIL-B and 12-bit resolution are not required | Choose only for legacy redesigns with unchanged PCB layout and relaxed accuracy/safety needs |
Compared with MLX90377GGO-ADB-210-RE, the MLX90377GDC-ADB-210-RE offers identical magnetic performance and safety capability in a smaller SOIC-8 footprint but lacks dual-die redundancy. Versus MLX90371GDC-ADB-010-RE, it adds 2 bits of resolution, extended temperature support, programmable transfer curves, and enhanced diagnostics - justifying upgrade in new automotive designs.

FAQ
What is the operating temperature range of the MLX90377GDC-ADB-210-RE?
The MLX90377GDC-ADB-210-RE operates from -40°C to +160°C, fully qualified for under-hood automotive environments. This range is guaranteed across all electrical specifications including supply current, output accuracy, and latency - with no derating required up to maximum junction temperature (175°C).
Does the MLX90377GDC-ADB-210-RE support SENT or SPC output protocols?
No, the MLX90377GDC-ADB-210-RE is configured exclusively for analog ratiometric and PWM output modes in High Speed Mode (option digit '1'). SENT and SPC require different option codes (-230, -280) and are not field-reprogrammable; this part's firmware and pinout are fixed for analog/PWM use.
Is the MLX90377GDC-ADB-210-RE pin-compatible with earlier Triaxis® sensors in SOIC-8?
Yes, the MLX90377GDC-ADB-210-RE maintains pin-to-pin compatibility with prior-generation Melexis Triaxis® sensors in SOIC-8 (e.g., MLX90363), including identical VDD, VSS, OUT, and VDEC pin locations and electrical behavior - enabling drop-in replacement in existing layouts.
What safety certification applies to the MLX90377GDC-ADB-210-RE in analog output mode?
In analog output mode, the MLX90377GDC-ADB-210-RE is certified ISO 26262 ASIL-B capable as a Safety Element out of Context (SEooC). This includes documented fault handling mechanisms, diagnostic coverage for broken-wire detection, and failure mode analysis - validated per Melexis Safety Manual Rev. 003.
How does the Linear Stray-Field Immune Mode function in the MLX90377GDC-ADB-210-RE?
The Linear Stray-Field Immune Mode in the MLX90377GDC-ADB-210-RE uses on-chip signal processing and magnetic concentrator geometry to reject orthogonal magnetic interference up to ±1 T while preserving sensitivity to the target axis. This is achieved through hardware-level differential sensing and adaptive filtering - confirmed in datasheet Section 8.2 for -2xx option codes.
