Product details
Overview
MLX90377GVE-ADB-210-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 package, operating from -40°C to 160°C, delivering 12-bit analog or PWM output with high-speed mode timing (≤100 µs latency), and certified ASIL-B for analog mode per ISO 26262 - used in automotive pedal and throttle position sensing.
For engineers reviewing the MLX90377GVE-ADB-210-RE datasheet, pinout, applications, or equivalent options, this page delivers verified package mapping (SMP-3), confirmed stray-field immune linear mode operation, real-world timing specs (startup ≤3 ms, latency ≤100 µs), and functional alternatives with documented output protocol and safety-level differences.
Technical Context
The MLX90377GVE-ADB-210-RE implements Triaxis® sensing of Bx, By, and Bz magnetic components using an on-die IMC, enabling absolute linear position decoding without mechanical contact. Its DSP performs real-time piecewise-linearization (up to 32 segments) and supports programmable transfer characteristics.
This variant operates in Linear Stray-Field Immune Mode (-2xx code), uses high-speed analog/PWM output configuration (-210), and is packaged in SMP-3 - a PCB-less single-mold package with integrated decoupling, requiring no external capacitors. It achieves ASIL-B compliance for analog output and supports SAE J2716 APR2016 SENT via reprogramming only in compatible variants (not this one).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including engine control modules and brake actuators. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct vehicle battery connection with reverse polarity protection up to -14 V. |
| Output Modes | Analog ratiometric (0–100% VDD) or PWM (duty cycle 0–100%) - both configurable in high-speed mode for ≤100 µs latency response. |
| Accuracy | ±1.0° typical angular error in linear stray-field immune mode - enables precise pedal stroke detection with <0.5 mm linearity error over full range. |
| Startup Time | ≤3 ms (high-speed analog/PWM) - ensures immediate position reporting after power-on for safety-critical actuation loops. |
| Safety Certification | ISO 26262 ASIL-B capable for analog output - validated as Safety Element out of Context (SEooC) with diagnostic coverage for open-circuit, short-to-rail, and supply faults. |

Applications
| Pedal Position Sensing | Throttle Position Sensing |
|---|---|
|
Use Scenario: Detecting accelerator or brake pedal stroke in electric/hybrid powertrains with temperature cycling from -40°C to +125°C. IC Role / Device Role / Timing Role: Absolute linear position transducer providing ratiometric analog output synchronized to ECU sampling at 10 kHz. Use Value: ±1.0° accuracy and stray-field immunity ensure consistent pedal mapping despite proximity to 48 V traction inverters and DC-DC converters. |
Use Scenario: Monitoring butterfly valve angle in gasoline direct injection engines exposed to under-hood temperatures up to +160°C. IC Role / Device Role / Timing Role: High-speed PWM position encoder with ≤100 µs latency feeding closed-loop air-fuel ratio control. Use Value: SMP-3 package withstands thermal shock during cold-start cycles; integrated decoupling prevents supply noise from corrupting PWM duty cycle fidelity. |
| Ride Height Control | Steering Angle Feedback |
|
Use Scenario: Measuring suspension travel in adaptive damping systems where magnets move linearly along shock absorber shafts. IC Role / Device Role / Timing Role: Stray-field immune linear position sensor interfacing with chassis domain controller via analog output. Use Value: Immunity to stray fields from adjacent ABS wheel speed sensors allows co-location within 15 mm without magnetic crosstalk. |
Use Scenario: Providing redundant steering angle data to ADAS lane-keeping and torque overlay functions in L2+ systems. IC Role / Device Role / Timing Role: ASIL-B compliant position source supporting fail-operational architecture when paired with TSSOP-16 dual-die variant. Use Value: On-chip diagnostics detect open-circuit faults within 50 ms, enabling graceful degradation to reduced steering assist rather than complete loss. |
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-RE | TSSOP-16 dual-die package with isolation resistance ≥4 MΩ between dies; higher pin count (16) and larger footprint. | Required for ASIL-C redundant architectures; supports independent diagnostics per die and fault-tolerant output arbitration. | Select when functional safety demands dual-channel independence per ISO 26262 Part 9 Annex D. |
| MLX90377GDC-ADB-310-RE | SOIC-8 package; Standard/Legacy Mode (not stray-field immune); same high-speed analog/PWM timing but lower magnetic immunity. | Suitable for non-safety-critical industrial rotary encoders where cost and legacy compatibility outweigh stray-field rejection needs. | Choose for cost-sensitive applications with controlled magnetic environments and no ASIL-B requirement. |
Compared with MLX90377GVE-ADB-210-RE, the TSSOP-16 alternative enables true hardware redundancy for ASIL-C, while the SOIC-8 variant trades stray-field immunity and package miniaturization for lower unit cost and broader design reuse - making each optimal for distinct safety and space-constrained tiers.

FAQ
What output protocols does the MLX90377GVE-ADB-210-RE support?
The MLX90377GVE-ADB-210-RE supports only analog ratiometric and PWM output modes in high-speed configuration. It does not support SENT or SPC protocols - those require different option codes (e.g., -230 or -280). The output mode is factory-programmed and cannot be changed in the field.
Is the MLX90377GVE-ADB-210-RE pin-compatible with other MLX90377 variants?
No - the MLX90377GVE-ADB-210-RE uses the 3-pin SMP-3 package, while SOIC-8 (8 pins), TSSOP-16 (16 pins), and DMP-4 (4 pins) variants have entirely different pin counts and layouts. Direct PCB replacement is not possible without redesign; SMP-3 requires dedicated land pattern per Melexis specification 19.4.
Does the MLX90377GVE-ADB-210-RE require external decoupling capacitors?
No. The SMP-3 package integrates optimized decoupling capacitance, eliminating the need for external 100 nF ceramic and 10 µF bulk capacitors required by SOIC-8 and TSSOP-16 variants. This reduces PCB area, assembly steps, and potential failure points from capacitor solder joints.
What is the functional safety qualification status of the MLX90377GVE-ADB-210-RE?
The MLX90377GVE-ADB-210-RE is ISO 26262 ASIL-B capable for analog output mode as a Safety Element out of Context (SEooC). It includes hardware diagnostics for supply, ground, and output continuity, with fault handling time intervals documented in section 15.3 of the datasheet. ASIL-C is not supported in this variant or package.
How does Linear Stray-Field Immune Mode affect magnetic circuit design for the MLX90377GVE-ADB-210-RE?
In Linear Stray-Field Immune Mode (-2xx), the MLX90377GVE-ADB-210-RE rejects interference from magnetic fields orthogonal to the intended sensing axis. This allows simplified magnet placement - e.g., a single diametrically magnetized cylinder moving linearly - without additional flux concentrators or shielding, reducing mechanical assembly tolerance sensitivity by up to 3×.
