Product details
Overview
MLX90377GVS-ADB-338-RX from Melexis is a monolithic Triaxis® Hall-based magnetic 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 enables robust absolute rotary or linear position sensing in automotive throttle, pedal, and steering applications without physical contact.
For engineers reviewing the MLX90377GVS-ADB-338-RX 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 functional safety qualification for safety-critical vehicle subsystems.
Technical Context
The MLX90377GVS-ADB-338-RX integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic field 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 code reporting and user-defined payload transmission within each SENT frame.
This variant operates exclusively in Standard/Legacy Mode with SENT output (3 μs tick time), uses no internal NVRAM trimming for stray-field immunity, and relies on external magnet configuration for angular or linear position decoding-no reprogramming of output protocol is possible post-manufacture per ordering code ADB-338.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables high-resolution, error-checked digital position reporting compatible with automotive ECUs. |
| Resolution | 12-bit - delivers 4096 distinct position steps over full scale, supporting sub-degree angular accuracy in rotary use cases. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including throttle bodies and suspension modules. |
| Supply Voltage | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct connection to vehicle battery with integrated reverse-polarity and overvoltage protection. |
| Functional Safety | ISO 26262 ASIL-C capable (SENT mode) - certified as Safety Element out of Context (SEooC) for integration into ASIL-C systems without additional hardware redundancy. |
| Package | DMP-4 (PCB-less dual mold) - surface-mount, 4-pin leadframe with straight leads (STD4 2.54 mm pitch), optimized for compact, high-vibration mounting. |
| Stray-Field Immunity | Standard/Legacy Mode (ADB-3xx) - no built-in stray-field compensation; requires external magnetic circuit design per application. |
Pinout & Package
DMP-4 is a PCB-less dual-mold package with 4 exposed leads, designed for direct soldering onto host PCBs. It provides pin-to-pin compatibility with prior Triaxis® generations and integrates decoupling capacitance internally.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog and digital sections; must be low-impedance connection to system ground plane. |
| 2 | VDD | Main supply input (4.5–18 V); includes reverse-polarity and overvoltage protection up to -18 V / +37 V. |
| 3 | OUT | SENT output driver (push-pull); delivers SAE J2716-compliant frames with CRC, status nibbles, and position data. |
| 4 | VSS | Second ground terminal - improves thermal dissipation and reduces ground loop impedance in high-noise environments. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute angle or linear displacement without mechanical wipers. |
| Secure Sensor SENT Format | Embedded error detection (CRC), diagnostic status nibble (SCN), and configurable user payload allow ECU-level fault isolation and calibration traceability. |
| Integrated Protection | Reverse polarity (-18 V), overvoltage (+37 V), and ESD (HBM ±8 kV) protection eliminate need for external TVS or diode networks. |
| ASIL-C SEooC Certification | Validated safety mechanisms (watchdog, memory ECC, signal path monitoring) meet ISO 26262 requirements for integration into ASIL-C systems without redesign. |
| DMP-4 Mechanical Robustness | Leadframe-based, PCB-less construction withstands >50 g mechanical shock and 2000+ thermal cycles - suitable for engine bay and chassis-mounted sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-333-RX | Same DMP-4 package and SENT output, but uses STD2 2.54 mm lead form (vs. STD4 in -338); identical electrical specs and ASIL-C capability. | Compatible in same footprint but requires verification of lead coplanarity and solder joint reliability for high-vibration mounting. | Select when legacy board layout uses shorter lead protrusion or tighter Z-height constraints. |
| MLX90377GDC-ADB-330-RE | SOIC-8 package (not PCB-less), same SENT protocol and -40°C to +160°C rating, but lacks DMP-4's integrated decoupling and mechanical ruggedness. | Suitable for lab prototypes or non-under-hood applications where PCB space allows SOIC-8 and vibration is minimal. | Choose only if DMP-4 mechanical integration is unnecessary and standard SMT assembly is preferred over direct lead soldering. |
Compared with MLX90377GVS-ADB-338-RX, the -333-RX offers identical performance in a mechanically distinct lead form, while the -330-RE trades DMP-4's ruggedness and compactness for conventional SOIC-8 manufacturability - neither is pin-compatible nor drop-in, and both require layout-specific validation.

FAQ
What output protocol does MLX90377GVS-ADB-338-RX support?
The MLX90377GVS-ADB-338-RX supports SENT output only, specifically SAE J2716 APR2016 with 3 μs tick time. It cannot be reconfigured to PWM, analog, or SPC modes - the output protocol is fixed by the ADB-338 option code at manufacture and is not user-programmable in the field.
Is MLX90377GVS-ADB-338-RX qualified for ASIL-C automotive safety applications?
Yes, MLX90377GVS-ADB-338-RX is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context (SEooC). Its certified safety mechanisms include memory ECC, watchdog timers, signal path monitoring, and CRC-protected SENT frames - all validated per Melexis' functional safety manual.
What is the package type and lead configuration of MLX90377GVS-ADB-338-RX?
MLX90377GVS-ADB-338-RX uses the DMP-4 package: a PCB-less dual-mold construction with four leads. Per ordering code ADB-338, it features STD4 2.54 mm pitch straight leads - confirmed in Section 19.3.3 of the datasheet - and integrates internal decoupling capacitance.
Can MLX90377GVS-ADB-338-RX operate directly from a 12 V vehicle battery?
Yes, MLX90377GVS-ADB-338-RX supports 6 V to 18 V battery-supplied operation with integrated reverse-polarity protection (-18 V) and overvoltage tolerance (+37 V for <60 s). No external protection circuitry is required, though a 100 nF ceramic capacitor between VDD and VSS is recommended per Section 16.3.
Does MLX90377GVS-ADB-338-RX provide stray-field immunity?
No, MLX90377GVS-ADB-338-RX operates in Standard/Legacy Mode (ADB-3xx), which does not include on-chip stray-field compensation. Stray-field immunity must be achieved externally via magnetic circuit design - unlike ADB-2xx (Linear) or ADB-5xx (Rotary) variants that embed dedicated compensation algorithms.
