Product details
Overview
MLX90377GGO-ADB-310-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for automotive and industrial rotary/linear sensing. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to 160°C, supports stray-field immune operation, and is ASIL-B capable in analog mode. It serves as a non-contacting replacement for potentiometers in throttle and pedal position systems.
For engineers reviewing the MLX90377GGO-ADB-310-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die package, programmable linear transfer characteristic (up to 32-piecewise), SENT/PWM/analog/SPC output flexibility, ISO26262 ASIL-B qualification for analog mode, and robustness against magnetic stray fields in legacy-mode configurations.
Technical Context
The MLX90377GGO-ADB-310-SP implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components, enabling absolute angular (0–360°) or linear position decoding with on-chip DSP and analog signal conditioning. Its architecture integrates a 12-bit ADC, ROM firmware, RAM, NVRAM for user programming, and temperature compensation.
This variant uses Standard/Legacy Mode (-3xx option code), supports Analog/PWM output in High Speed Mode, and is packaged in TSSOP-16 (GO code). It features dual-die redundancy, isolation resistance ≥4 MΩ between dice, and operates across 4.5–5.5 V (regulated) or 6–18 V (battery) supply ranges with 9–11.5 mA supply current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Resolution | 12-bit for analog, PWM, SENT, and SPC modes - enables ±0.1° angular accuracy in typical rotary applications. |
| Operating Temperature | -40°C to +160°C - qualified for under-hood automotive environments including engine control and transmission modules. |
| Supply Voltage Range | 4.5–5.5 V (regulated) or 6–18 V (battery) - supports direct connection to vehicle battery with reverse polarity and overvoltage protection. |
| Output Modes | Analog ratiometric and PWM (High Speed Mode) - allows flexible interface with MCU ADCs or timer capture inputs without external protocol decoders. |
| Functional Safety | ISO26262 ASIL-B capable for analog output - certified as Safety Element out of Context (SEooC) for integration into ASIL-B systems. |
| Magnetic Immunity | Stray-field robust in Standard/Legacy Mode - maintains accuracy under external magnetic interference up to ±1 T, critical for EV powertrain proximity sensing. |
| Startup Time | Tstup ≤ 10 ms (PWM), Tinit ≤ 5 ms (SENT) - ensures rapid system readiness after power-on for safety-critical actuator feedback loops. |
Pinout & Package
TSSOP-16 package (GO code) with dual-die configuration for functional redundancy and internal isolation ≥4 MΩ between dice. Includes built-in decoupling pins per die and dedicated ground/supply pairs for noise resilience.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDEC1 / VDEC2 | Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to suppress high-frequency switching noise. |
| 2, 10 | VSS1 / VSS2 | Independent ground terminals per die - must be connected to separate low-impedance ground planes to maintain isolation integrity. |
| 3, 11 | VDD1 / VDD2 | Independent supply inputs per die - enable independent power sequencing and fault containment between redundant channels. |
| 6, 15 | OUT2 / OUT1 | Separate push-pull/PWM output drivers per die - support dual-signal monitoring or cross-checking in safety-critical systems. |
| 4, 12 | Input1 / Input2 | Test/external measurement inputs - unused in standard operation; recommended tied to VSS for EMC compliance. |
| 5, 13 | Test2 / Test1 | Factory test points - not intended for end-user access; connect to VSS to minimize EMI susceptibility. |
| 7, 8, 14, 16 | N.C. | No-connect pins - must be grounded per datasheet recommendation to reduce radiated emissions and improve EMC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® 3D Hall Sensing | Simultaneous Bx, By, Bz detection enables single-chip absolute angle/position measurement without mechanical gearing or multi-sensor arrays. |
| Programmable Transfer Characteristic | Up to 32-point piecewise-linear calibration - allows precise linearization of magnet nonlinearity across full stroke without host MCU computation. |
| Redundant Dual-Die Architecture | TSSOP-16 package integrates two independent sensor dies - supports diagnostic comparison and fail-operational behavior in ASIL-C systems. |
| Stray-Field Immunity | Validated operation under ±1 T external DC fields - eliminates need for magnetic shielding in crowded EV motor or inverter environments. |
| Configurable Output Protocols | Hardware-selectable analog/PWM/SENT/SPC - permits reuse of same IC across multiple ECU platforms with differing interface requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90371GGO-ADB-310-SP | Single-die TSSOP-16, identical pinout and output modes, but lacks dual-die redundancy and isolation rating. | ASIL-B only; not suitable for ASIL-C decomposed architectures requiring physical channel separation. | Select when cost sensitivity outweighs need for hardware-level redundancy and inter-die isolation. |
| TLV493DW2B6HTSA1 | Infineon 3D Hall sensor in TSSOP-16; 12-bit I²C output only, no analog/PWM/SENT native support. | Requires external MCU for protocol translation and linearization; no NVRAM-based calibration storage. | Choose for I²C-based systems where host processing headroom exists and magnetic immunity validation is customer-responsible. |
Compared with MLX90371GGO-ADB-310-SP and TLV493DW2B6HTSA1, the MLX90377GGO-ADB-310-SP uniquely combines dual-die TSSOP-16 packaging, ASIL-B analog mode certification, and native multi-protocol output - enabling drop-in deployment in safety-critical automotive position feedback without redesigning signal conditioning or safety architecture.

FAQ
What output protocols does the MLX90377GGO-ADB-310-SP support?
The MLX90377GGO-ADB-310-SP supports analog ratiometric and PWM outputs in High Speed Mode, as defined by its ADB-310 option code. It does not support SENT or SPC output - those require ADB-330 or ADB-380 variants. The analog output scales ratiometrically with VDD (0–100% VDD), while PWM provides 12-bit resolution with configurable period and duty cycle mapping.
Is the MLX90377GGO-ADB-310-SP pin-compatible with other MLX90377 package variants?
No - the MLX90377GGO-ADB-310-SP uses the TSSOP-16 package (GO code) with 16 pins and dual-die layout, whereas SOIC-8 (DC), DMP-4 (VS), and SMP-3 (VE) variants have different pin counts, assignments, and internal architectures. Pin compatibility exists only within the same package family (e.g., other GO-code TSSOP-16 variants), not across package types.
Does the MLX90377GGO-ADB-310-SP require external programming for basic operation?
No - the MLX90377GGO-ADB-310-SP ships pre-programmed with Standard/Legacy Mode, Analog/PWM High Speed configuration. No external programming is needed to achieve functional analog or PWM output. Programming via PTC (Programming through Connector) is optional and only required for custom calibration, transfer function definition, or diagnostic parameter tuning.
What is the maximum magnetic field tolerance of the MLX90377GGO-ADB-310-SP?
The MLX90377GGO-ADB-310-SP maintains specified accuracy under external magnetic stray fields up to ±1 T (10,000 Gauss), as validated in Standard/Legacy Mode per datasheet Section 8.3. This immunity is achieved via on-chip magnetic concentrator (IMC) design and differential signal processing, eliminating need for external shielding in high-interference zones like EV inverters.
Can the MLX90377GGO-ADB-310-SP be used in ASIL-C systems?
Yes - the MLX90377GGO-ADB-310-SP is ISO26262 ASIL-C capable when used with SENT, PWM, or SPC output modes, and ASIL-B capable with analog output. Its TSSOP-16 dual-die architecture, inter-die isolation ≥4 MΩ, and integrated diagnostics (e.g., broken-wire detection, watchdog timers) support decomposition into ASIL-C safety mechanisms per Melexis Safety Manual Rev. 003.
