Product details
Overview
MLX90377GGO-ADB-380-TU from Melexis is a Triaxis® monolithic magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit SPC (Short PWM Code) output, operates from -40°C to 160°C, supports stray-field immune operation in Standard/Legacy Mode, and is qualified per ISO 26262 ASIL-C for SPC output-used in automotive throttle and pedal position systems.
For engineers reviewing the MLX90377GGO-ADB-380-TU datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (TSSOP-16), confirmed SPC timing (1.5 μs tick), functional safety classification (ASIL-C), programmable transfer characteristic (up to 32-point PWL), and real-world use context for non-contacting position feedback in harsh environments.
Technical Context
The MLX90377GGO-ADB-380-TU integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angle or linear displacement decoding without mechanical wear. Its on-chip DSP performs real-time signal conditioning, temperature compensation, and piecewise-linearization of the magnetic response.
This variant is factory-configured for SPC output mode with 1.5 μs tick time, uses dual-die TSSOP-16 packaging for redundancy, and implements ASIL-C safety mechanisms-including CRC-protected communication, watchdog timers, and diagnostic reporting via status nibbles-specifically validated for SPC protocol operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) with 1.5 μs tick time-enables deterministic, low-latency position reporting compatible with automotive ECU input capture units. |
| Resolution | 12-bit angular/linear position data-supports ±0.1° typical accuracy over full scale in Standard/Legacy Mode. |
| Operating Temp | -40°C to +160°C junction range-validated for under-hood automotive applications including throttle bodies and suspension modules. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6–18 V (battery)-supports direct connection to vehicle battery with reverse-polarity and overvoltage protection. |
| Safety Certification | ISO 26262 ASIL-C capable for SPC output-certified as Safety Element out of Context (SEooC) with documented fault handling time interval & diagnostic coverage. |
| Magnetic Sensitivity | ±1 T maximum flux density-designed for operation with standard NdFeB magnets in compact mechanical layouts. |
| Package | TSSOP-16 dual-die-provides electrical isolation (>4 MΩ between dies) and functional redundancy for fail-operational systems. |
Pinout & Package
TSSOP-16 dual-die package with 0.65 mm pitch; includes isolated supply/ground domains for redundancy and built-in decoupling capability at VDEC1/VDEC2 pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die-require local 100 nF ceramic capacitors to ensure stable internal regulator operation and EMC robustness. |
| 2, 10 | VSS1 / VSS2 | Independent ground terminals per die-must be connected to separate PCB ground planes or star-grounded to maintain isolation integrity. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die-enable independent power sequencing and support dual-rail monitoring for fault detection. |
| 4, 12 | Input1 / Input2 | Test/external measurement inputs-unused in production; recommended tied to GND for optimal EMC performance. |
| 5, 13 | Test2 / Test1 | Factory test access points-no user functionality; must be grounded per datasheet recommendation. |
| 6, 15 | OUT2 / OUT1 | Independent SPC output channels per die-support dual-signal transmission for cross-checking or fail-safe arbitration logic. |
| 7, 8, 14, 16 | N.C. | No-connect pins-electrically isolated; must be grounded to minimize radiated emissions and improve noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall sensing | Enables single-chip absolute position measurement from rotating or linearly moving magnets-eliminates need for external concentrators or multi-sensor assemblies. |
| Programmable PWL transfer | Up to 32-point piecewise-linear calibration-corrects magnet nonlinearity and mechanical tolerances without host MCU intervention. |
| SPC output with 1.5 μs tick | Delivers deterministic, low-jitter position updates synchronized to external trigger pulses-ideal for closed-loop control with <100 μs latency budget. |
| Dual-die TSSOP-16 redundancy | Provides hardware-level fault containment-each die operates independently with isolated power, ground, and outputs for ASIL-C compliance. |
| Stray-field immune mode | Validated against external magnetic interference up to ±1 mT-ensures reliable operation near motors, solenoids, or high-current traces. |

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-330-TU | SENT output instead of SPC; identical TSSOP-16 package, temperature rating, and ASIL-C qualification. | Requires SENT-capable ECU input; offers richer diagnostic framing but longer frame duration than SPC. | Select when ECU supports SENT APR2016 and higher diagnostic bandwidth is prioritized over minimal latency. |
| MLX90377GDC-ADB-380-TU | SOIC-8 single-die package instead of TSSOP-16 dual-die; same SPC output mode and -40°C to 160°C rating. | Lacks hardware redundancy and inter-die isolation-suitable for ASIL-B or non-safety-critical applications. | Select when board space is constrained and functional safety requirements do not mandate dual-die architecture. |
Compared with MLX90377GGO-ADB-330-TU, the MLX90377GGO-ADB-380-TU reduces communication latency by ~40% via SPC's shorter frame structure; compared with MLX90377GDC-ADB-380-TU, it adds fail-operational capability through electrically isolated dual dies-critical for ASIL-C throttle or brake subsystems.

FAQ
What output protocol does the MLX90377GGO-ADB-380-TU support?
The MLX90377GGO-ADB-380-TU is factory-configured exclusively for SPC (Short PWM Code) output with a fixed 1.5 μs tick time. It does not support SENT, PWM, or analog modes-even via reprogramming-as stated in the datasheet's ordering code definition: "Option Code - SW configuration: output mode, protocol" where '8' explicitly denotes SPC mode. This hardwired configuration ensures deterministic timing for safety-critical control loops.
Is the MLX90377GGO-ADB-380-TU certified for functional safety applications?
Yes, the MLX90377GGO-ADB-380-TU is ISO 26262 ASIL-C capable for SPC output mode as a Safety Element out of Context (SEooC). Its certification covers fault detection mechanisms-including CRC-protected SPC frames, watchdog timers, and diagnostic nibble reporting-as validated in the functional safety manual. The dual-die TSSOP-16 package enables hardware redundancy required for ASIL-C decomposition in throttle and pedal systems.
What package type and pin count does the MLX90377GGO-ADB-380-TU use?
The MLX90377GGO-ADB-380-TU uses a TSSOP-16 package with dual-die construction. Per datasheet Table 1 and Section 19.2, the 'GO' temperature/package code maps to TSSOP-16, and pin definitions confirm 16 terminals-including independent VDD/VSS/VDEC/OUT pairs for each die plus dedicated test and NC pins-all verified in the official Melexis datasheet Revision 003.
Can the MLX90377GGO-ADB-380-TU be reprogrammed to change its output mode?
No, the MLX90377GGO-ADB-380-TU cannot be reprogrammed to change its output mode. As specified in the datasheet's Ordering Codes Information (Table 2), "The output protocols are not interchangeable by reprogramming at the end-user." The 'ADB-380' option code permanently configures the device for SPC output during factory programming-requiring hardware-level selection at order time.
What is the operating temperature range of the MLX90377GGO-ADB-380-TU?
The MLX90377GGO-ADB-380-TU operates from -40°C to +160°C ambient temperature, as defined by the 'G' temperature code in its part number and confirmed in Section 4 (Absolute Maximum Ratings) and Section 6 (General Electrical Specifications) of the datasheet. This range is validated for continuous operation in under-hood automotive environments including throttle bodies and suspension modules.
