Overview
MLX90377GVE-ADB-330-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC in SMP-3 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 in automotive safety-critical throttle and pedal position sensing.
For engineers reviewing the MLX90377GVE-ADB-330-RE datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), SENT protocol timing compliance (SAE J2716 APR2016), stray-field immune operation in Standard/Legacy Mode, and functional safety qualification per ISO 26262.
Technical Context
The MLX90377GVE-ADB-330-RE 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. It decodes absolute rotary (0–360°) or linear position from magnet motion without contact.
This variant operates exclusively in Standard/Legacy Mode with SENT output (3 μs tick), supports programmable piecewise-linear transfer characteristics (up to 32 segments), and uses on-chip NVRAM for calibration and configuration storage - all within a PCB-less SMP-3 package rated for 160°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90377GDC-ADB-330-RE | SOIC-8 package (8-pin, leaded), same SENT output mode and firmware revision, higher thermal mass but larger footprint. | Preferred where board-level reworkability, legacy SOIC assembly, or higher decoupling capacitance tolerance is required. | Select when PCB layout allows SOIC-8 and thermal derating margin is needed beyond SMP-3's 160°C rating. |
| MLX90377GO-ADB-330-RE | TSSOP-16 dual-die package with inter-die isolation (>4 MΩ), identical SENT functionality but redundant architecture. | Required for ASIL-D systems or where hardware-level redundancy (e.g., dual-channel EPS) mandates physically isolated dies. | Choose only when dual-die fault containment and isolation per ISO 26262 Annex D are mandatory - not a drop-in replacement. |
Compared with MLX90377GDC-ADB-330-RE and MLX90377GO-ADB-330-RE, the MLX90377GVE-ADB-330-RE offers the smallest footprint and highest packaging integration for magnet-proximate mounting, while retaining full SENT protocol compliance and ASIL-C capability - making it optimal for space- and weight-constrained automotive actuators.

The MLX90377GVE-ADB-330-RE supports SENT (Single Edge Nibble Transmission) output only, with 3 μs tick time per SAE J2716 APR2016. It is factory-configured for this mode and cannot be reprogrammed to PWM, analog, or SPC outputs - the ADB-330 option code permanently selects SENT functionality.
Is the MLX90377GVE-ADB-330-RE pin-compatible with other MLX90377 variants?
No - the MLX90377GVE-ADB-330-RE uses the SMP-3 package (3-pin), while SOIC-8 (8-pin) and TSSOP-16 (16-pin) variants have different pin counts, layouts, and terminal functions. Direct PCB replacement is not possible without redesign; SMP-3 requires dedicated footprint and magnet-mounting geometry.
Does the MLX90377GVE-ADB-330-RE require external programming for basic operation?
No - the MLX90377GVE-ADB-330-RE ships pre-programmed with Standard/Legacy Mode and SENT output enabled. No end-user programming is needed for initial deployment; calibration and advanced features (e.g., PWL points) are optional and performed via Melexis' PTM software using the INPUT/TEST pads under controlled conditions.
What is the maximum operating temperature for the MLX90377GVE-ADB-330-RE?
The MLX90377GVE-ADB-330-RE is rated for -40°C to +160°C ambient temperature, with a maximum junction temperature of +175°C. Its SMP-3 package is qualified for continuous operation at 160°C, making it suitable for under-hood locations such as throttle bodies and suspension control arms.
How does the MLX90377GVE-ADB-330-RE achieve stray-field immunity?
The MLX90377GVE-ADB-330-RE achieves stray-field immunity through its Triaxis® Hall architecture and on-chip signal processing that rejects common-mode interference from orthogonal magnetic fields. In Standard/Legacy Mode (ADB-3xx), it maintains accuracy in fields up to ±100 mT without external shielding - validated per ISO 11452-8.
