Product details
Overview
MLX90377GVS-ADB-338-SP from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in DMP-4 package, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to +160°C, and certified ASIL-C capable for SENT mode. It decodes rotary or linear magnet motion without physical contact, enabling throttle, pedal, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GVS-ADB-338-SP datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance (SAE J2716 APR2016), stray-field immunity in Standard/Legacy Mode, DMP-4 PCB-less dual-mold mechanical form factor, and ASIL-C safety qualification for functional safety-critical vehicle control loops.
Technical Context
The MLX90377GVS-ADB-338-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, a 12-bit ADC, DSP-based signal processing engine, and SENT output stage with Secure Sensor format encoding. Its architecture supports real-time error reporting, user-defined values, and CRC-protected frames.
This variant operates exclusively in Standard/Legacy Mode with SENT output (3 μs tick), uses no internal NVRAM reprogramming for protocol change, and relies on external pull-up resistors (10–55 kΩ) matched to SENT timing constraints. It features reverse polarity and overvoltage protection up to -14 V and 37 V, respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables deterministic, low-latency transmission of angle data with embedded diagnostics and CRC. |
| Resolution | 12-bit - delivers 0.088° angular resolution over 360° full scale, sufficient for high-precision throttle and pedal actuation feedback. |
| Operating Temp | -40°C to +160°C - qualified for under-hood and transmission-mounted applications without external thermal derating. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - supports direct connection to automotive 12 V systems with integrated protection circuitry. |
| Safety Certification | ISO 26262 ASIL-C (SENT mode) - validated as Safety Element out of Context for use in ASIL-C safety mechanisms without additional hardware redundancy. |
| Package | DMP-4 (PCB-less dual mold) - surface-mountable, compact 3.2 × 2.5 × 0.9 mm footprint with straight leads (STD4 2.54 mm pitch), optimized for space-constrained modules. |
| Magnetic Immunity | Standard/Legacy Mode (-3xx code) - provides robust operation against stray fields typical in engine bay environments per datasheet Section 8.3. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with 4 terminals, designed for direct soldering onto flex or rigid substrates. Pin-to-pin compatible with prior Triaxis® generations. Dimensions: 3.2 mm × 2.5 mm × 0.9 mm (L × W × H), lead pitch 2.54 mm, STD4 trim configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital domains; must be connected to system ground plane for EMC stability and accurate measurement. |
| 2 | VDD | Main supply input (4.5–18 V); includes reverse polarity and overvoltage protection up to -14 V / +37 V for automotive transients. |
| 3 | OUT | SENT output driver (push-pull); requires external 10–55 kΩ pull-up to VDD or separate supply for proper voltage-level compliance and timing margin. |
| 4 | VSS | Dedicated second ground terminal - improves current return path integrity and reduces ground bounce in high-noise environments. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-330-RE | Same DMP-4 package and SENT output, but delivered in standard tape-and-reel (RE) vs. sample pack (SP); identical electrical and safety specs. | No functional difference - differs only in packing form (RE = 2500 pcs/reel; SP = sample quantity). | Select MLX90377GVS-ADB-330-RE for production volumes; MLX90377GVS-ADB-338-SP is functionally identical but supplied in sample configuration. |
| MLX90377GDC-ADB-330-RE | SOIC-8 package instead of DMP-4; same SENT output, -40°C to +160°C rating, and ASIL-C capability. | Requires PCB footprint redesign due to larger SOIC-8 (4.9 × 6.0 mm) vs. DMP-4 (3.2 × 2.5 mm); lacks PCB-less mounting flexibility. | Choose MLX90377GDC-ADB-330-RE when legacy SOIC layout exists or when higher thermal mass is needed; DMP-4 preferred for miniaturized modules. |
Compared with MLX90377GVS-ADB-338-SP, the ADB-330-RE variant offers identical sensing performance and safety qualification but differs in packaging format, while the SOIC-8 alternative trades compactness and direct-mount capability for standardized through-hole-compatible assembly - both require no firmware or protocol changes.

FAQ
What output protocol does the MLX90377GVS-ADB-338-SP support?
The MLX90377GVS-ADB-338-SP supports SENT output only, configured for SAE J2716 APR2016 fast SENT with 3 μs tick time. It does not support PWM, analog, or SPC modes - this is fixed by factory programming per ordering code ADB-338. The MLX90377GVS-ADB-338-SP cannot be reprogrammed to alternate protocols in the field.
Is the MLX90377GVS-ADB-338-SP qualified for ASIL-C applications?
Yes, the MLX90377GVS-ADB-338-SP is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context (SEooC). This qualification covers fault detection, diagnostic coverage, and safe state behavior per the MLX90377 safety manual. The MLX90377GVS-ADB-338-SP meets ASIL-C requirements without requiring redundant hardware in the signal path.
What is the package type and mechanical compatibility of the MLX90377GVS-ADB-338-SP?
The MLX90377GVS-ADB-338-SP uses the DMP-4 package: a PCB-less dual-mold construction measuring 3.2 × 2.5 × 0.9 mm with 2.54 mm lead pitch (STD4 trim). It is pin-to-pin compatible with prior-generation Melexis Triaxis® sensors in DMP-4, enabling drop-in replacement in existing flex or rigid board designs without layout modification.
Does the MLX90377GVS-ADB-338-SP require external decoupling capacitors?
No, the MLX90377GVS-ADB-338-SP integrates internal decoupling and does not require external VDEC capacitors - unlike SOIC-8 or TSSOP-16 variants. The DMP-4 package includes built-in capacitance optimized for stable operation across its full -40°C to +160°C range, simplifying PCB design and reducing BOM count for the MLX90377GVS-ADB-338-SP.
What magnetic configurations are supported by the MLX90377GVS-ADB-338-SP?
The MLX90377GVS-ADB-338-SP operates in Standard/Legacy Mode (-3xx option code), supporting both rotary (0–360°) and linear position sensing with standard magnet arrangements. It is not configured for stray-field immune variants (-1xx, -2xx, -5xx); its magnetic sensitivity and calibration are optimized for conventional flux concentrator-based designs per datasheet Section 8.3.
