Product details

Overview

MLX90377GGO-ADB-330-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC designed for automotive and industrial rotary/linear sensing. It delivers 12-bit SENT output with 3 μs tick time, operates from −40 °C to +160 °C, supports SAE J2716 APR2016 compliance, and is ASIL-C capable in SENT mode. It decodes magnet position via B_x, B_y, B_z field components in TSSOP-16 dual-die package.

For engineers reviewing the MLX90377GGO-ADB-330-RE datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SENT protocol timing, stray-field immune operation mode, ISO26262 safety architecture, and TSSOP-16 package interface details essential for pedal, throttle, and steering wheel position system design.

Technical Context

The MLX90377GGO-ADB-330-RE implements Triaxis® Hall front-end sensing of all three magnetic flux components (B_x, B_y, B_z) with on-chip DSP-based signal processing for absolute angular or linear position decoding. Its SENT output uses SAE J2716 APR2016 frame format with 12-bit resolution and 3 μs tick time, delivering error codes and user-defined values in Secure Sensor format.

This variant is configured in Standard/Legacy Mode with SENT output only (non-reprogrammable), uses TSSOP-16 dual-die packaging for redundancy, and achieves ASIL-C capability per ISO26262 as a Safety Element out of Context - with fault handling time interval ≤ 10 ms and diagnostic coverage ≥ 90% for SENT path.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Protocol	SENT (SAE J2716 APR2016), 12-bit resolution, 3 μs tick time - enables high-integrity serial communication with embedded error detection and status reporting.
Operating Temperature	−40 °C to +160 °C - qualified for under-hood automotive applications including throttle and pedal sensors.
Safety Certification	ISO26262 ASIL-C capable (SENT mode), ASIL-B (analog mode) - certified as Safety Element out of Context with documented fault mechanisms and diagnostics.
Supply Voltage Range	4.5 V to 5.5 V (regulated) or 6–18 V (battery) - supports direct vehicle battery connection in PWM mode; SENT mode requires regulated supply.
Package	TSSOP-16 dual-die - provides full hardware redundancy with isolation resistance ≥4 MΩ between dies for fail-operational systems.
Magnetic Sensing	Triaxis® 3-axis Hall front-end - enables absolute position measurement without mechanical contact using rotating or linear magnets.
Startup Time (SENT)	T_init ≤ 10 ms, T_stup ≤ 20 ms - defines time from power-on to first valid angle transmission, critical for engine control loop initialization.

Pinout & Package

TSSOP-16 dual-die package with 0.65 mm pitch, 5.0 × 4.4 mm body size, and exposed thermal pad. Designed for redundant signal paths with isolated die-to-die grounding and supply domains.

Pin/Terminal	Circuit Role	Design Meaning
1, 9	VDEC1 / VDEC2	Dedicated decoupling pins per die - require local 100 nF ceramic capacitors to minimize noise coupling between redundant channels.
2, 10	VSS1 / VSS2	Independent ground terminals per die - enable galvanic isolation between redundant signal chains; must be routed separately on PCB.
3, 11	VDD1 / VDD2	Independent supply inputs per die - support independent power domain monitoring and fault containment in ASIL-C systems.
4, 12	Input1 / Input2	Test/external measurement inputs - unused in production; recommended to tie to VSS for EMC robustness.
5, 13	Test2 / Test1	Factory test access points - not intended for end-user use; connect to VSS for optimal EMC performance.
6, 15	OUT2 / OUT1	Redundant SENT output drivers - deliver identical SENT frames from independent dies; used for cross-checking in safety-critical ECUs.
7, 8, 14, 16	N.C.	No-connect pins - must be tied to VSS to suppress parasitic antenna effects and meet automotive EMC requirements.

Key Features

Feature	Design Value
Triaxis® 3D Hall Sensing	Simultaneous acquisition of B_x, B_y, B_z enables true absolute position without calibration drift across temperature and lifetime.
SENT Output Compliance	Full SAE J2716 APR2016 implementation with CRC, status nibbles, and programmable message content - eliminates need for external protocol translation.
Dual-Die Redundancy	Independent VDD/VSS/VDEC per die with ≥4 MΩ isolation - supports fail-operational architectures required for ASIL-C steering and brake position sensing.
Stray-Field Immunity	Configured in Standard/Legacy Mode (−3xx code), optimized for robust operation in high-EMI environments like engine bays and motor drives.
On-Chip Signal Processing	DSP-based linearization (up to 32-point PWL), filtering, and temperature compensation - reduces host MCU computational load and improves accuracy stability.

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90377GDC-ADB-330-RE	SOIC-8 single-die package, no hardware redundancy, lower thermal dissipation rating.	Suitable for non-safety-critical linear position sensing where ASIL-C is not mandated.	Select when cost and board space constrain redundancy requirements but SENT output and Triaxis® sensing are retained.
MLX90377GVS-ADB-330-RE	DMP-4 PCB-less package with straight leads, 4-pin footprint, no isolation between domains.	Targeted for compact, low-cost throttle/pedal modules requiring minimal assembly steps and no dual-channel validation.	Choose for space-constrained consumer or industrial applications where TSSOP-16 routing complexity must be avoided.

Compared with MLX90377GGO-ADB-330-RE, the SOIC-8 variant sacrifices die-level redundancy and isolation for lower cost and simpler layout, while the DMP-4 version trades package robustness and thermal performance for ultra-compact integration - neither offers the ASIL-C-certified dual-die fault containment required for steering or braking position sensing.

FAQ

What output protocol does the MLX90377GGO-ADB-330-RE support?

The MLX90377GGO-ADB-330-RE supports SENT output only, compliant with SAE J2716 APR2016 standard at 3 μs tick time. It does not support analog, PWM, or SPC modes - the output protocol is fixed by factory programming and cannot be changed in the field. This ensures deterministic timing and diagnostic behavior required for ASIL-C systems.

Is the MLX90377GGO-ADB-330-RE pin-compatible with other MLX90377 variants?

No - the MLX90377GGO-ADB-330-RE uses the TSSOP-16 dual-die package, which has different pin count, pinout, and electrical isolation requirements than SOIC-8 (8-pin), DMP-4 (4-pin), or SMP-3 (3-pin) variants. Direct PCB replacement is not possible without layout revision due to distinct supply, ground, and output pin assignments per die.

Does the MLX90377GGO-ADB-330-RE require external programming after soldering?

No - the MLX90377GGO-ADB-330-RE is fully factory-programmed for Standard/Legacy Mode with SENT output. All configuration bits, including transfer characteristic, filtering, and diagnostics, are pre-set and locked. No end-user programming interface (e.g., PTC voltage ramp) is needed for basic operation.

What is the maximum operating temperature of the MLX90377GGO-ADB-330-RE?

The MLX90377GGO-ADB-330-RE is rated for continuous operation from −40 °C to +160 °C ambient temperature. This specification applies to the full TSSOP-16 package and is validated per AEC-Q100 Grade 0 requirements, making it suitable for under-hood automotive applications such as throttle bodies and brake pedals.

How does the dual-die architecture of the MLX90377GGO-ADB-330-RE support functional safety?

The MLX90377GGO-ADB-330-RE implements hardware redundancy with two independent dies in one TSSOP-16 package, each with separate VDD, VSS, VDEC, and OUT pins. Isolation resistance ≥4 MΩ between dies enables cross-die comparison for fault detection, satisfying ISO26262 ASIL-C requirements for position sensing in steering and braking systems without external redundancy circuitry.
