Product details
Overview
MLX90377GVS-ADB-330-RX 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 rotary/linear position sensing in automotive throttle, pedal, and steering applications.
For engineers reviewing the MLX90377GVS-ADB-330-RX datasheet, pinout, applications, or equivalent options, this page provides verified functional context, SENT protocol timing, stray-field immune operation mode, ASIL-C safety capability, and DMP-4 mechanical interface details critical for automotive sensor integration.
Technical Context
The MLX90377GVS-ADB-330-RX implements Triaxis® Hall sensing of Bx, By, and Bz magnetic field components to compute absolute angular or linear position without contact. Its on-chip DSP supports programmable piecewise-linear transfer characteristics (up to 32 segments) and configurable SENT frame formatting 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 achieves ASIL-C compliance per ISO 26262 as a Safety Element out of Context - validated for SENT, PWM, and SPC modes but ASIL-B for analog.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SENT (Single Edge Nibble Transmission) per SAE J2716 APR2016, fixed 3 μs tick time - enables high-resolution, error-coded digital transmission to ECU without external ADC. |
| Resolution | 12-bit position data - delivers 0.088° angular resolution over 360° or sub-millimeter linear precision depending on magnet geometry. |
| Operating Temp | -40°C to +160°C - qualified for under-hood automotive environments including throttle bodies and suspension modules. |
| Supply Range | 4.5 V to 5.5 V (regulated) or 6 V to 18 V (battery) - supports direct vehicle battery connection with reverse polarity and overvoltage protection. |

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-RX | Analog/PWM output mode, high-speed mode - no SENT protocol, different output driver configuration and timing. | Used where ECU lacks SENT receiver but requires analog voltage or PWM duty-cycle input. | Select when legacy analog interface or PWM timing constraints dominate over digital diagnostics and error coding. |
| MLX90377GVS-ADB-380-RX | SPC (Short PWM Code) output mode, 1.5 μs tick time - different frame structure, lower resolution (10-bit), no status nibble. | Deployed in cost-sensitive systems requiring basic position feedback without advanced SENT diagnostics. | Choose for simpler ECUs with SPC-only receivers and reduced diagnostic requirements versus ASIL-C SENT path. |
Compared with MLX90377GVS-ADB-330-RX, the ADB-310-RX offers analog/PWM flexibility but lacks SENT's embedded error detection, while the ADB-380-RX trades resolution and diagnostic depth for faster SPC frame rate - all share identical DMP-4 packaging, temperature range, and Triaxis® sensing core.
