Product details
Overview
MLX90377GDC-ADB-210-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SOIC-8 package, operating from -40°C to 160°C, supporting high-speed analog/PWM output with linear stray-field immunity, and compliant with ISO 26262 ASIL-B for analog mode. It delivers 12-bit resolution position data for non-contact rotary or linear sensing in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GDC-ADB-210-TU datasheet, pinout, applications, or equivalent options, key selection criteria include its linear stray-field immune magnetic configuration, SOIC-8 thermal robustness, high-speed analog/PWM timing compliance, and ASIL-B safety qualification for analog output mode.
Technical Context
The MLX90377GDC-ADB-210-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz components, enabling absolute angular (0–360°) or linear position decoding via on-chip DSP and 12-bit ADC. Its linear stray-field immune mode (-2xx option code) uses dedicated magnetic circuit compensation to reject orthogonal interference fields up to ±1 T.
This variant supports high-speed analog/PWM output (–21x code), with startup time ≤5 ms in analog mode and latency <1.5 ms at 25°C. The SOIC-8 package includes internal voltage regulation, reverse polarity protection, and programmable transfer characteristics using 4–32 piecewise-linear points.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-210-TU | TSSOP-16 dual-die package with isolation resistance >4 MΩ between dies; higher pin count; no VDEC pin | Required for redundant safety architectures (e.g., ASIL-C) where die-level independence is mandated | Select when dual-die fault containment or inter-die isolation is required beyond ASIL-B |
| MLX90377GVE-ADB-210-TU | SMP-3 PCB-less single-mold package; 3-pin footprint; integrated capacitors; no N.C. pins | Optimized for space-constrained modules where board area and assembly cost are prioritized over test access | Select for compact actuator-integrated designs where SOIC-8 footprint is prohibitive |
Compared with MLX90377GDC-ADB-210-TU, the TSSOP-16 alternative enables ASIL-C system-level compliance via physical die separation, while the SMP-3 variant trades testability and decoupling flexibility for minimal footprint and built-in passive components - both retain identical stray-field immunity and high-speed analog/PWM functionality.

FAQ
What is the operating temperature range of the MLX90377GDC-ADB-210-TU?
The MLX90377GDC-ADB-210-TU operates from -40°C to +160°C, fully qualified for under-hood automotive applications including throttle bodies and brake pedals. This range is validated per AEC-Q100 Grade 0 and includes guaranteed performance of analog/PWM output timing, stray-field immunity, and ASIL-B diagnostics across the entire span without derating.
Does the MLX90377GDC-ADB-210-TU support SENT or SPC output protocols?
No, the MLX90377GDC-ADB-210-TU is configured exclusively for high-speed analog ratiometric and PWM output modes, as indicated by its -210 option code. SENT and SPC require different option codes (-230 and -280 respectively) and are implemented in separate device variants - output protocol is fixed at manufacture and not reprogrammable in the field.
How does the linear stray-field immunity feature work in the MLX90377GDC-ADB-210-TU?
The MLX90377GDC-ADB-210-TU implements linear stray-field immunity via on-chip magnetic compensation algorithms that actively cancel orthogonal interference fields up to ±1 T. This is achieved through differential Triaxis® Hall element pairing and real-time DSP correction, validated for use in pedal sensors located near high-current brake actuators or motor drivers.
What is the startup time specification for the MLX90377GDC-ADB-210-TU in analog high-speed mode?
The MLX90377GDC-ADB-210-TU achieves ≤5 ms startup time in analog high-speed mode (-21x), defined as the interval from VDD crossing 4.1 V to first valid position output on the OUT pin. This value is guaranteed across -40°C to +160°C and includes internal regulator stabilization, ADC initialization, and DSP convergence - critical for meeting cold-start ECU timing budgets.
Can the MLX90377GDC-ADB-210-TU be used in ASIL-C safety architectures?
The MLX90377GDC-ADB-210-TU is certified ISO 26262 ASIL-B for analog output mode only. For ASIL-C compliance, Melexis offers the dual-die TSSOP-16 variant (e.g., MLX90377GGO-ADB-210-TU) with inter-die isolation >4 MΩ and independent diagnostic paths - the SOIC-8 version lacks the physical redundancy required for ASIL-C decomposition.
