Product details
Overview
MLX90377GGO-ADB-530-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary position sensing in high-field stray-field immune configurations. It delivers 12-bit SENT output with 3 μs tick time, operates from -40°C to +160°C, and uses TSSOP-16 dual-die packaging for ASIL-C functional safety compliance in automotive throttle and steering applications.
For engineers reviewing the MLX90377GGO-ADB-530-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its Rotary Stray-Field Immune Mode (High Field variant), SENT protocol compliance per SAE J2716 APR2016, ASIL-C capability, and TSSOP-16 package isolation specification.
Technical Context
The MLX90377GGO-ADB-530-SP implements a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field components, enabling robust absolute angular position decoding up to 360° without mechanical contact. Its on-chip DSP performs real-time signal conditioning and piecewise-linearization using up to 32 segments.
This variant is configured exclusively for SENT output mode with 3 μs tick time and operates in Rotary Stray-Field Immune Mode (High Field variant), requiring specific magnet geometry and field strength ≥ ±40 mT. It supports ISO 26262 ASIL-C as a Safety Element out of Context (SEooC) for SENT, PWM, and SPC outputs.

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-RE | Same TSSOP-16 package and -40°C to +160°C rating, but Standard/Legacy Mode (not Rotary Stray-Field Immune); SENT output with identical 3 μs tick time. | Requires lower magnetic field (±20 mT) and lacks stray-field immunity - suitable only in magnetically quiet environments. | Select when cost optimization is prioritized over field immunity and system-level magnetic noise is controlled. |
| MLX90371GGO-ADB-530-SP | Same Rotary Stray-Field Immune (High Field) mode and TSSOP-16 package, but legacy 10-bit resolution and no ASIL-C certification; SENT output with 3 μs tick time. | Lacks ISO 26262 ASIL-C qualification and offers reduced angular resolution - insufficient for new ASIL-C designs. | Consider only for legacy system refresh where ASIL-C is not mandated and 10-bit resolution meets control loop requirements. |
Compared with MLX90377GGO-ADB-330-RE, the MLX90377GGO-ADB-530-SP adds critical stray-field immunity and higher field tolerance for under-hood deployment; versus MLX90371GGO-ADB-530-SP, it delivers ASIL-C compliance and 12-bit precision essential for next-generation automotive safety systems.

FAQ
What output protocol does the MLX90377GGO-ADB-530-SP support?
The MLX90377GGO-ADB-530-SP supports SENT output only, configured per SAE J2716 APR2016 with 3 μs tick time. It does not support analog, PWM, or SPC modes. This fixed protocol is defined by the ADB-530 option code and cannot be reprogrammed in the field - the MLX90377GGO-ADB-530-SP must be selected at order time for SENT-based systems requiring high immunity and ASIL-C compliance.
Is the MLX90377GGO-ADB-530-SP pin-compatible with other MLX90377 variants in TSSOP-16?
Yes, all MLX90377 variants in TSSOP-16 package (GO code) share identical pinout, footprint, and soldering profile. The MLX90377GGO-ADB-530-SP uses pins 1–16 exactly as defined in Table 5 of the datasheet, including VDEC1/VSS1/VDD1/Input1/Test2/OUT2/N.C./N.C./VDEC2/VSS2/VDD2/Input2/Test1/N.C./OUT1/N.C. No PCB redesign is needed when substituting within the GO family.
What magnetic field strength is required for reliable operation of the MLX90377GGO-ADB-530-SP?
The MLX90377GGO-ADB-530-SP requires a minimum magnetic field strength of ±40 mT in Rotary Stray-Field Immune Mode (High Field variant). This is significantly higher than the ±20 mT requirement of Standard/Legacy Mode variants. Field strength must be verified across the full -40°C to +160°C operating range using the magnet's temperature coefficient and air gap tolerances.
Does the MLX90377GGO-ADB-530-SP support functional safety certification for ASIL-C systems?
Yes, the MLX90377GGO-ADB-530-SP is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context (SEooC). This includes documented safety mechanisms such as CRC validation, watchdog timers, memory ECC, and diagnostic coverage for sensor front-end and signal path - all validated per Melexis safety manual referenced in section 15 of the datasheet.
How is redundancy implemented in the MLX90377GGO-ADB-530-SP TSSOP-16 package?
The MLX90377GGO-ADB-530-SP implements hardware redundancy via two fully independent sensor dies in one TSSOP-16 package, with ≥4 MΩ isolation resistance between VSS1 and VSS2. Each die has dedicated supply (VDD1/VDD2), decoupling (VDEC1/VDEC2), and output (OUT1/OUT2) paths. This enables cross-die comparison for fault detection in ASIL-C architectures without external components.
