Product details
Overview
MLX90377GVS-ADB-330-TU 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 supporting automotive pedal/throttle position sensing with ASIL-C functional safety compliance.
For engineers reviewing the MLX90377GVS-ADB-330-TU datasheet, pinout, applications, or equivalent options, this page provides verified pin definitions, SENT protocol timing, stray-field immune operation mode, ISO26262 ASIL-C capability for SENT output, and direct alternative part comparisons for automotive position-sensing designs.
Technical Context
The MLX90377GVS-ADB-330-TU implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular or linear position without mechanical contact. Its on-chip DSP performs real-time signal conditioning, piecewise-linearization (up to 32 segments), and SENT frame encoding per SAE J2716 APR2016.
This variant operates in Standard/Legacy Mode with SENT output only (not reprogrammable), uses internal 12 MHz main clock (±3.5% total drift), and embeds diagnostics including broken-wire detection on VDD/VSS and CRC-protected SENT frames - all validated for ASIL-C as Safety Element out of Context per ISO26262.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (SAE J2716 APR2016), 3 μs tick time - enables high-resolution, error-coded digital transmission compatible with automotive ECUs. |
| Resolution | 12-bit - delivers 4096 distinct position values over full scale, sufficient for <0.1° angular or sub-mm linear accuracy. |
| Operating Temp | -40°C to +160°C - supports under-hood automotive environments without external thermal derating. |
| Supply Voltage | 4.5–5.5 V (regulated) or 6–18 V (battery) - dual-range operation eliminates need for external LDO in 12 V systems. |
| Functional Safety | ISO26262 ASIL-C capable for SENT output - certified for safety-critical throttle/pedal applications without additional hardware redundancy. |
| Package | DMP-4 (PCB-less dual mold) - compact 4-pin surface-mount form factor with built-in decoupling, optimized for space-constrained modules. |
| Stray-Field Immunity | Standard/Legacy Mode (-3xx code) - designed for robust operation in magnetically noisy environments without external shielding. |
Pinout & Package
DMP-4 package: PCB-less dual-mold construction with integrated capacitors, 4-pin surface-mount footprint, 2.54 mm pitch, straight leads (STD0 configuration per datasheet section 19.3.1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for analog/digital domains - must be low-impedance connection to system GND plane. |
| 2 | VDD | Main supply input - accepts 4.5–18 V; internal regulator powers core logic and Hall front-end. |
| 3 | OUT | SENT output driver - push-pull, 12-bit encoded frames, 3 μs tick time, open-drain compatible with pull-up to 5 V or 18 V. |
| 4 | VSS | Second ground terminal - improves EMC performance and current return path separation; tied to same net as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous measurement of Bx, By, Bz enables true 3D magnetic field decoding for absolute rotary/linear position without mechanical wear. |
| SENT Output Compliance | Full SAE J2716 APR2016 implementation with status & communication nibble (SCN), CRC, and diagnostic flags - reduces ECU software overhead. |
| Programmable Transfer Function | Up to 32-point piecewise-linear (PWL) calibration stored in NVRAM - allows precise compensation of magnet nonlinearity and mechanical tolerances. |
| Broken-Wire Detection | Passive diagnostics for open VDD or VSS connections - reports fault via SENT SCN without requiring active polling or external circuitry. |
| On-Chip Signal Processing | DSP-based filtering, temperature compensation, and angle computation - eliminates need for external microcontroller in basic position-sensing functions. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GVS-ADB-310-TU | Same DMP-4 package and temperature range, but PWM output instead of SENT; 12-bit resolution, 10 kHz max update rate. | Used where ECU lacks SENT receiver but supports PWM edge-timing capture; no built-in CRC or diagnostic nibble. | Select when legacy ECU integration requires PWM compatibility and ASIL-C is not mandated. |
| MLX90377GDC-ADB-330-RE | Identical SENT functionality and firmware, but SOIC-8 package (8-pin, 150 mil width) with separate VDEC pin and larger PCB footprint. | Suitable for prototyping or applications requiring test access to Input/Test pins; less compact than DMP-4 for volume production. | Choose for development flexibility or when board layout accommodates SOIC-8 and decoupling capacitor placement is preferred externally. |
Compared with MLX90377GVS-ADB-330-TU, the PWM variant trades SENT diagnostics and ECU compatibility for simpler signal acquisition, while the SOIC-8 version retains identical sensing performance but sacrifices miniaturization - making the DMP-4 SENT variant optimal for space-constrained, safety-certified automotive modules.

FAQ
What output protocol does the MLX90377GVS-ADB-330-TU support?
The MLX90377GVS-ADB-330-TU supports SENT output only, configured per SAE J2716 APR2016 with 3 μs tick time. It cannot be reprogrammed to PWM, analog, or SPC modes - the output protocol is fixed at manufacture per ordering code ADB-330. This ensures deterministic timing and ASIL-C compliance for safety-critical automotive use cases.
Is the MLX90377GVS-ADB-330-TU pin-compatible with other MLX90377 variants in DMP-4 package?
Yes, all MLX90377 variants in DMP-4 package - including MLX90377GVS-ADB-300-TU, MLX90377GVS-ADB-310-TU, and MLX90377GVS-ADB-330-TU - share identical 4-pin pinout (VSS-VDD-OUT-VSS) and mechanical footprint. Only the firmware-configured output behavior differs; no PCB redesign is needed when switching between DMP-4 variants.
Does the MLX90377GVS-ADB-330-TU require external decoupling capacitors?
No, the MLX90377GVS-ADB-330-TU in DMP-4 package integrates decoupling capacitance internally, eliminating the need for external VDD/VSS bypass capacitors. This simplifies layout, reduces bill-of-materials count, and enhances reliability in vibration-prone automotive environments where solder joint integrity is critical.
What functional safety level is certified for the MLX90377GVS-ADB-330-TU SENT output?
The MLX90377GVS-ADB-330-TU SENT output is certified ISO26262 ASIL-C capable as a Safety Element out of Context (SEooC). This includes built-in diagnostics such as CRC-protected frames, status & communication nibble (SCN), and passive broken-wire detection - enabling its use in throttle and pedal position sensing without additional hardware redundancy.
Can the MLX90377GVS-ADB-330-TU operate directly from a 12 V vehicle battery?
Yes, the MLX90377GVS-ADB-330-TU supports 6–18 V battery-supplied operation in PWM mode, and 4.5–5.5 V regulated supply for SENT mode. For SENT applications powered from 12 V battery, an external LDO or DC-DC converter is required to regulate down to 5 V, as specified in the electrical characteristics table for SENT timing stability and noise immunity.
