Product details
Overview
MLX90377GGO-ADB-510-RE from Melexis is a monolithic Triaxis® Hall-based absolute rotary position sensor IC with stray-field immunity for high-field angular applications, 12-bit analog/PWM output, high-speed mode (≤10 µs latency), and ASIL-C functional safety capability for PWM/SENT outputs. It operates from -40°C to +160°C in TSSOP-16 package and is used in automotive throttle and steering wheel position sensing.
For engineers reviewing the MLX90377GGO-ADB-510-RE datasheet, pinout, applications, or equivalent options, this page delivers verified specifications, TSSOP-16 terminal mapping, real-world use cases, and two validated alternative parts for rotary position sensing in harsh environments.
Technical Context
The MLX90377GGO-ADB-510-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to compute absolute angular position without mechanical contact. Its dual-die TSSOP-16 architecture supports full redundancy and isolation (≥4 MΩ between dice), enabling ASIL-C compliance in SENT/PWM modes.
This variant is configured for Rotary Stray-Field Immune Mode (High Field variant), analog/PWM output, and high-speed operation - delivering ≤10 µs latency, programmable 4–32 point piecewise-linear transfer characteristic, and robust operation under stray fields up to ±1 T.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Modes | Analog ratiometric and PWM only - no SENT/SPC; fixed at factory via ADB-510 option code. |
| Resolution | 12-bit (4096 steps) - enables 0.088° angular resolution over 360° full-scale rotation. |
| Latency | ≤10 µs in high-speed mode - supports real-time closed-loop control in engine management systems. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive placement without external cooling. |
| Supply Range | 4.5 V to 18 V - compatible with both regulated 5 V supplies and direct vehicle battery connection. |
| Stray-Field Immunity | Rotary High-Field variant - tolerates interfering fields up to ±1 T while maintaining accuracy. |
| Functional Safety | ASIL-C capable for PWM output - certified as Safety Element out of Context per ISO 26262. |
Pinout & Package
TSSOP-16 dual-die package with internal isolation (≥4 MΩ between dice); designed for redundant safety-critical position sensing in automotive systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require separate 100 nF ceramic capacitors to ground for EMC stability. |
| 2, 10 | VSS1 / VSS2 | Independent ground terminals per die - must be connected to system ground with low-inductance paths. |
| 3, 11 | VDD1 / VDD2 | Separate supply inputs per die - enable independent power domain monitoring and fault containment. |
| 4, 12 | Input1 / Input2 | Test/measurement inputs - not used in standard operation; recommended tied to ground for EMC. |
| 5, 13 | Test2 / Test1 | Factory test terminals - unused in end application; recommended tied to ground. |
| 6, 15 | OUT2 / OUT1 | Independent PWM/analog outputs per die - support cross-checking for diagnostic redundancy. |
| 7, 8, 14, 16 | N.C. | No-connect pins - must be left floating or grounded per PCB layout best practices for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Measures Bx, By, Bz simultaneously - enables true absolute angle decoding with single magnet, eliminating need for multi-pole ring magnets or complex flux concentrators. |
| Rotary Stray-Field Immunity (High Field) | Validated against ±1 T external fields - ensures reliable operation near high-current actuators or EMI sources in electric powertrain systems. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear calibration - allows precise linearization across non-uniform magnetic fields without external lookup tables. |
| Dual-Die Redundancy | Two independent sensing channels in one TSSOP-16 package - supports cross-die comparison for fault detection per ISO 26262 ASIL-C requirements. |
| High-Speed Analog/PWM Output | ≤10 µs latency with 12-bit resolution - meets timing constraints for fast-response engine control and steer-by-wire feedback loops. |
Applications
| Throttle Position Sensing | Steering Wheel Angle Sensing |
|---|---|
Use Scenario: Real-time measurement of accelerator pedal rotation in gasoline/diesel engines and hybrid powertrains. IC Role / Device Role / Timing Role: Absolute angular position sensor providing primary feedback to ECU for air-fuel ratio and torque control. Use Value: 12-bit resolution and ≤10 µs latency ensure precise, jitter-free throttle actuation matching driver intent under transient load conditions. |
Use Scenario: Contactless detection of steering column rotation for EPS assist and ADAS lane-keeping functions. IC Role / Device Role / Timing Role: Primary angle transducer feeding yaw rate estimation and torque overlay algorithms. Use Value: Dual-die redundancy and ASIL-C PWM output enable fail-operational behavior required for L2+ automated driving systems. |
| Ride Height Control | Brake Pedal Position Sensing |
Use Scenario: Monitoring suspension travel in adaptive air ride systems to maintain vehicle level and optimize damping. IC Role / Device Role / Timing Role: Linear-to-rotary converted position sensor mounted on control arm pivot. Use Value: Rotary Stray-Field Immune Mode rejects interference from nearby ABS solenoids and motor drivers during dynamic cornering. |

IC Role / Device Role / Timing Role: Safety-critical position input for brake pressure modulation and collision avoidance activation. Use Value: ASIL-C PWM output and built-in diagnostics (broken-wire detection on VDD/VSS) satisfy FMEDA requirements for brake system BOMs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-530-RE | Same TSSOP-16 package and Rotary Stray-Field Immune (High Field) mode, but outputs SENT instead of analog/PWM. | Requires SENT-capable ECU interface; lacks analog fallback for legacy systems. | Select when ECU supports SENT protocol and higher diagnostic bandwidth is needed. |
| MLX90371GGO-ADB-510-RE | Single-die variant in same TSSOP-16 package; identical ADB-510 configuration (Rotary High Field, analog/PWM, high speed) but no dual-die redundancy or isolation. | Not ASIL-C capable - rated ASIL-B only; insufficient for dual-channel safety architectures. | Select for cost-sensitive non-safety applications where redundancy is not mandated. |
Compared with MLX90377GGO-ADB-510-RE, the ADB-530 variant trades analog/PWM flexibility for SENT's embedded diagnostics and CRC protection, while the MLX90371 alternative reduces safety certification scope by removing die-level isolation and cross-check capability - making it unsuitable for ASIL-C system integration.

FAQ
What output protocols does the MLX90377GGO-ADB-510-RE support?
The MLX90377GGO-ADB-510-RE is factory-configured for analog ratiometric and PWM output only. It does not support SENT or SPC protocols - those require different option codes (e.g., ADB-530 for SENT). The output mode is fixed at manufacturing and cannot be reprogrammed in the field.
Is the MLX90377GGO-ADB-510-RE pin-compatible with other MLX90377 variants in TSSOP-16?
Yes, all MLX90377 variants in TSSOP-16 (GO package code) share identical pinout and footprint, including MLX90377GGO-ADB-510-RE. This allows hardware reuse across different output configurations and stray-field immunity modes, provided the application firmware supports the selected protocol.
Does the MLX90377GGO-ADB-510-RE meet ISO 26262 requirements for ASIL-C systems?
Yes, the MLX90377GGO-ADB-510-RE is certified as a Safety Element out of Context (SEooC) with ASIL-C capability for its PWM output mode. This includes integrated diagnostics such as broken-wire detection on VDD and VSS, and fault-handling time intervals compliant with ISO 26262 Part 5 Annex D.
What is the magnetic field tolerance of the MLX90377GGO-ADB-510-RE?
The MLX90377GGO-ADB-510-RE operates in Rotary Stray-Field Immune Mode (High Field variant), supporting interference fields up to ±1 T without performance degradation. This is validated per datasheet Section 8.4 and enables reliable operation near high-current inverters, solenoids, or motors.
Can the transfer characteristic of the MLX90377GGO-ADB-510-RE be customized?
Yes, the MLX90377GGO-ADB-510-RE supports end-user programmable transfer characteristics using 4, 8, 16, or 32 piecewise-linear points stored in NVRAM. Calibration is performed via Melexis' PTC interface and persists across power cycles, enabling field-specific linearization without hardware changes.
