Product details
Overview
MLX90377GGO-ADB-230-RE from Melexis is a Triaxis® Hall-based monolithic magnetic position sensor IC in TSSOP-16 dual-die package, delivering 12-bit SENT output with 3 μs tick time, ASIL-C functional safety capability, and linear stray-field immunity for absolute rotary/linear position sensing in automotive throttle and pedal systems.
For engineers reviewing the MLX90377GGO-ADB-230-RE datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, SENT protocol timing, stray-field immune accuracy specs, and direct alternatives for automotive position-sensing designs requiring ISO 26262 compliance.
Technical Context
The MLX90377GGO-ADB-230-RE implements Triaxis® Hall sensing of Bx, By, and Bz magnetic components to compute absolute angular or linear position without mechanical contact. Its dual-die TSSOP-16 architecture supports full redundancy with isolated ground paths (4 MΩ min isolation resistance between VSS1/VSS2) and independent SENT output channels.
This variant operates exclusively in Linear Stray-Field Immune Mode (-2xx code), uses SENT v4.0 (SAE J2716 APR2016), and delivers 12-bit resolution with programmable transfer characteristic (up to 32-point PWL). Startup time includes Tinit (circuit readiness) and Tstup (first valid angle transmission), both defined per SENT timing spec.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT v4.0 (SAE J2716 APR2016) with 3 μs tick time - enables robust serial communication with CRC, diagnostics, and user-defined data fields in automotive networks. |
| Functional Safety | ISO 26262 ASIL-C capable for SENT output - certified Safety Element out of Context (SEooC) with fault handling time interval ≤ 10 ms. |
| Resolution | 12-bit position data - supports 0–360° rotary or full-stroke linear measurement with ≤ ±0.5° typical angular error in Linear Stray-Field Immune Mode. |
| Operating Temp | −40°C to +160°C - qualified for under-hood automotive applications including throttle bodies and brake pedals. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6–18 V (battery) - supports direct connection to vehicle battery with reverse voltage protection to −18 V. |
| Stray-Field Immunity | Linear Stray-Field Immune Mode (−2xx option code) - rejects external magnetic interference up to ±1 T while maintaining accuracy on target magnet motion. |
| Package | TSSOP-16 dual-die - provides physical redundancy, 4 MΩ inter-die isolation, and separate supply/ground pins per die (VDD1/VSS1 & VDD2/VSS2). |
Pinout & Package
TSSOP-16 dual-die package with 0.65 mm pitch, 5.0 × 4.4 mm body, and exposed thermal pad. Designed for high-reliability automotive placement with separate power/ground domains per die.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to VSS1/VSS2 for stable analog/digital regulation. |
| 2, 10 | VSS1 / VSS2 | Independent ground returns per die - enable galvanic isolation and fault containment; must be routed separately on PCB. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - support redundant power delivery and allow differential supply monitoring. |
| 4, 12 | Input1 / Input2 | Test/external measurement inputs - unused in production; recommended tied to VSS for EMC. |
| 5, 13 | Test2 / Test1 | Factory test terminals - not user-accessible; tie to VSS for optimal EMC performance. |
| 6, 15 | OUT2 / OUT1 | Independent SENT output drivers per die - deliver identical 12-bit position frames; support cross-checking for safety-critical validation. |
| 7, 8, 14, 16 | N.C. | No-connect pins - internally unconnected; tie to VSS to minimize EMI susceptibility. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall front-end | Simultaneous Bx, By, Bz sensing enables true 3D magnetic field decoding - eliminates need for external concentrators in linear/rotary position topologies. |
| Linear Stray-Field Immune Mode | Hardware-optimized signal path rejects orthogonal magnetic interference - maintains ±0.5° accuracy under ±1 T stray fields common near motors or solenoids. |
| Dual-die TSSOP-16 redundancy | Two independent sensor dies with isolated supplies/grounds - supports ASIL-C decomposition via hardware diversity and cross-monitoring. |
| SENT v4.0 with diagnostics | Embedded status & communication nibble (SCN), CRC, and configurable error reporting - reduces host ECU software overhead for fault detection and logging. |
| Programmable transfer characteristic | Up to 32-point piecewise-linear (PWL) calibration - enables precise linearization across non-uniform magnet trajectories without external lookup tables. |
Applications
| Throttle Position Sensing | Pedal Position Sensing |
|---|---|
|
Use Scenario: Monitoring accelerator pedal angle in gasoline/diesel powertrains to determine engine torque demand. IC Role / Device Role / Timing Role: Absolute angular position sensor with SENT output delivering 12-bit angle data at ≥1 kHz update rate and <10 ms fault handling time. Use Value: Enables ASIL-C compliant closed-loop engine control with real-time diagnostics, eliminating potentiometer wear and contact failure risks. |

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 | Analog/PWM output instead of SENT; same Linear Stray-Field Immune Mode and TSSOP-16 package. | Suitable for legacy ECU interfaces lacking SENT receivers; requires external ADC or PWM timer capture. | Select when system lacks SENT decode capability but requires identical stray-field immunity and temperature range. |
| MLX90377GDC-ADB-230-RE | SOIC-8 single-die package instead of TSSOP-16 dual-die; same SENT output, Linear Stray-Field Immune Mode, and electrical specs. | Used where space constraints prohibit TSSOP-16 or redundancy is not required for ASIL decomposition. | Select for cost-sensitive or space-constrained applications where ASIL-C is met via software-level diagnostics rather than hardware redundancy. |
Compared with MLX90377GGO-ADB-230-RE, the ADB-210-RE variant trades SENT protocol support for analog/PWM flexibility but retains identical stray-field rejection and temperature rating, while the ADB-230-RE in SOIC-8 sacrifices dual-die redundancy for smaller footprint and lower cost-both remain drop-in replacements only in non-safety-critical contexts.

FAQ
What output protocol does the MLX90377GGO-ADB-230-RE support?
The MLX90377GGO-ADB-230-RE supports SENT v4.0 (SAE J2716 APR2016) with 3 μs tick time exclusively - it is factory-configured for this mode and cannot be reprogrammed to PWM, analog, or SPC output. This fixed configuration ensures deterministic timing and ASIL-C compliance without runtime protocol switching.
Is the MLX90377GGO-ADB-230-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-230-RE. Pin definitions - such as VDD1/VSS1/VDEC1 for die 1 and VDD2/VSS2/VDEC2 for die 2 - are consistent across ADB-2xx, ADB-3xx, and ADB-5xx option codes in the GO package.
Does the MLX90377GGO-ADB-230-RE meet ISO 26262 requirements for ASIL-C systems?
Yes, the MLX90377GGO-ADB-230-RE is certified as a Safety Element out of Context (SEooC) for ASIL-C when used with SENT output, per ISO 26262-5:2018. Its dual-die architecture, built-in diagnostics, and ≤10 ms fault handling time interval satisfy hardware-level requirements for decomposition in safety-critical automotive control loops.
What is the magnetic stray-field immunity specification for the MLX90377GGO-ADB-230-RE?
The MLX90377GGO-ADB-230-RE operates in Linear Stray-Field Immune Mode (−2xx option code), rejecting external magnetic interference up to ±1 T orthogonal to the sensing axis while maintaining ≤±0.5° angular error. This is achieved through on-chip signal processing and dedicated magnetic front-end calibration, not external shielding.
Can the MLX90377GGO-ADB-230-RE be used in single-die configurations or only dual-die?
The MLX90377GGO-ADB-230-RE is exclusively a dual-die device housed in the TSSOP-16 package (GO code), with physically separate dies providing independent VDD1/VSS1 and VDD2/VSS2 connections. It is not available in single-die form - variants like MLX90377GDC-ADB-230-RE use SOIC-8 but lack hardware redundancy.
