Product details
Overview
MLX90377GGO-ADB-510-SP from Melexis is a Triaxis® Hall-based monolithic magnetic position sensor IC designed for absolute rotary position sensing in high-field stray-field immune configurations. It delivers 12-bit resolution analog and PWM outputs, operates from -40°C to +160°C, supports SAE J2716 APR2016 SENT protocol, and is ISO 26262 ASIL-C capable in SENT/PWM/SPC modes. It enables non-contact throttle and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GGO-ADB-510-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die package, rotary stray-field immunity (high-field variant), high-speed analog/PWM output mode, and ASIL-C safety certification - all critical for robust automotive position feedback under EMI stress.
Technical Context
The MLX90377GGO-ADB-510-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular position decoding up to 360° without mechanical contact. Its on-chip DSP performs real-time signal conditioning, piecewise-linearization (up to 32-point), and programmable transfer characteristics tailored for rotary magnet topologies.
This variant uses the TSSOP-16 dual-die package with isolated ground/supply domains (VSS1/VSS2, VDD1/VDD2) and supports redundant output architecture. Its output stage delivers 12-bit analog ratiometric or PWM signals with <10 µs latency in high-speed mode and includes built-in diagnostics including broken-wire detection on VDD and VSS lines.

Pinout & Package
TSSOP-16 dual-die package with 0.65 mm pitch, 5.0 mm × 4.4 mm footprint, and thermal pad for enhanced heat dissipation in high-temperature automotive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDEC1 | Decoupling capacitor connection (Die 1) | Stabilizes internal analog regulator for Die 1; requires 100 nF ceramic capacitor to VSS1 |
| VSS1 | Ground reference (Die 1) | Isolated ground domain for Die 1; must be routed separately from VSS2 to maintain redundancy integrity |
| VDD1 | Power supply input (Die 1) | Accepts 4.5–18 V; powers analog front-end and DSP core of Die 1 |
| Input1 | Test/measurement interface (Die 1) | Factory test access; not intended for end-user use; recommended tied to GND for EMC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GGO-ADB-530-SP | Same TSSOP-16 package and rotary stray-field immunity, but outputs SENT instead of analog/PWM; requires external SENT decoder | Used where host ECU has native SENT interface and higher diagnostic bandwidth is needed | Select when SENT protocol integration simplifies ECU signal conditioning versus analog/PWM filtering and ADC resources |
| MLX90377GDC-ADB-510-SP | Identical functionality and ADB-510 configuration, but in SOIC-8 package (single die, no redundancy) | Suitable for cost-sensitive, non-safety-critical applications where ASIL-C is not required | Choose for legacy designs with SOIC-8 footprints or where dual-die redundancy is unnecessary |
Compared with MLX90377GGO-ADB-530-SP, the MLX90377GGO-ADB-510-SP avoids SENT decoding overhead and reduces ECU processing load; compared with MLX90377GDC-ADB-510-SP, it adds functional safety via dual-die isolation and cross-die diagnostics - essential for ASIL-C automotive subsystems.

FAQ
What output protocols does the MLX90377GGO-ADB-510-SP support?
The MLX90377GGO-ADB-510-SP supports analog ratiometric and PWM output modes only. It does not support SENT or SPC protocols - this is fixed by the ADB-510 option code programmed at factory. The output mode cannot be changed in the field, and reprogramming is not supported. Both outputs deliver 12-bit resolution with high-speed timing optimized for automotive closed-loop control.
Is the MLX90377GGO-ADB-510-SP certified for functional safety applications?
Yes, the MLX90377GGO-ADB-510-SP is ISO 26262 ASIL-C capable for PWM output and ASIL-B capable for analog output, certified as a Safety Element out of Context (SEooC). Its TSSOP-16 dual-die architecture, independent power/ground domains, and built-in diagnostics (broken-wire detection, watchdogs, CRC-protected NVRAM) enable integration into ASIL-C systems like electronic throttle control and brake-by-wire.
What is the significance of the "GO" and "510" in MLX90377GGO-ADB-510-SP?
The "GO" denotes the TSSOP-16 package with dual-die redundancy, while "510" specifies Rotary Stray-Field Immune Mode (High Field variant) with Analog/PWM output in High Speed Mode. This combination ensures immunity to strong external magnetic fields (>±1 T) and fast response (<10 ms startup, <10 µs latency), making MLX90377GGO-ADB-510-SP ideal for under-hood automotive position sensing where EMI resilience is critical.
Can the MLX90377GGO-ADB-510-SP be used in linear position sensing applications?
No - the MLX90377GGO-ADB-510-SP is configured exclusively for rotary stray-field immune operation (high-field variant), optimized for angular position decoding from rotating magnets. While the base MLX90377 family supports linear modes (e.g., ADB-2xx codes), the ADB-510 option locks the device to rotary topology and associated magnetic calibration. For linear sensing, select MLX90377GGO-ADB-210-SP or similar linear-stray-immune variants.
What decoupling capacitors are required for the MLX90377GGO-ADB-510-SP?
The MLX90377GGO-ADB-510-SP requires two 100 nF ceramic decoupling capacitors: one between VDEC1 and VSS1 for Die 1, and another between VDEC2 and VSS2 for Die 2. These must be placed within 2 mm of their respective pins and use X7R or better dielectric. Additional bulk capacitance (e.g., 1–10 µF tantalum) is recommended at the VDD1/VDD2 inputs to suppress battery ripple in automotive environments.
