Product details
Overview
MLX90377GVE-ADB-330-TU from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for rotary or linear non-contact sensing, delivering 12-bit SENT output with 3 μs tick time, operating from -40°C to 160°C, and qualified to ISO 26262 ASIL-C for SENT mode. It enables high-reliability pedal, throttle, and steering wheel position sensing in automotive powertrain and chassis systems.
For engineers reviewing the MLX90377GVE-ADB-330-TU datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance (SAE J2716 APR2016), stray-field immunity in Standard/Legacy Mode, SMP-3 package footprint, and ASIL-C functional safety capability for safety-critical vehicle control loops.
Technical Context
The MLX90377GVE-ADB-330-TU 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. Its architecture supports absolute angular measurement up to 360° or linear displacement via external magnet configuration without mechanical wear.
This variant operates exclusively in Standard/Legacy Mode with SENT output (3 μs tick time), uses SMP-3 PCB-less single-mold packaging, and implements programmable diagnostics including broken-wire detection on VDD and VSS. It does not support analog, PWM, or SPC output modes - those require different option codes.
Key Specifications

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 ASIL-C capability, but larger footprint and no integrated decoupling. | Preferred for prototyping or legacy PCB designs requiring through-hole or SOIC-compatible layout; lacks SMP-3's space and EMC advantages. | Select when board real estate permits and existing SOIC-8 footprints exist; avoid for new compact sensor modules. |
| MLX90377GO-ADB-330-RE | TSSOP-16 dual-die package with isolation resistance >4 MΩ between dies; identical SENT functionality but higher pin count and redundancy-ready architecture. | Required for dual-channel ASIL-D systems where die-level redundancy is mandated; adds complexity and cost for single-channel use cases. | Choose only when hardware-level fault tolerance (e.g., lockstep dual output) is required by safety architecture. |
Compared with MLX90377GDC-ADB-330-RE and MLX90377GO-ADB-330-RE, the MLX90377GVE-ADB-330-TU delivers identical SENT performance and ASIL-C capability in the smallest possible form factor (SMP-3), eliminating external capacitors and reducing assembly steps - ideal for volume automotive sensor modules where size, weight, and BOM count are critical.

FAQ
What output protocol does the MLX90377GVE-ADB-330-TU support?
The MLX90377GVE-ADB-330-TU supports SENT output only, configured per SAE J2716 APR2016 with 3 μs tick time. It does not support analog, PWM, or SPC modes - those require different option codes (e.g., ADB-300 for analog/PWM). The SENT interface delivers 12-bit position data with embedded diagnostics and CRC protection, making it suitable for ASIL-C automotive control systems.
Is the MLX90377GVE-ADB-330-TU pin-compatible with other MLX90377 variants?
No - the MLX90377GVE-ADB-330-TU uses the SMP-3 3-pin package, which is physically and electrically distinct from SOIC-8 (8-pin), TSSOP-16 (16-pin), or DMP-4 (4-pin) variants. Pin count, spacing, and terminal functions differ; PCB layout must be specific to SMP-3. No mechanical or electrical interchangeability exists across package types.
Does the MLX90377GVE-ADB-330-TU require external decoupling capacitors?
No - the SMP-3 package integrates decoupling capacitance internally, eliminating the need for external VDD/VSS bypass capacitors. This reduces bill-of-materials count and PCB area, simplifies layout, and improves EMC performance. Designers should still follow Melexis' recommended grounding and trace routing practices per the datasheet Section 16.4.
What functional safety level does the MLX90377GVE-ADB-330-TU achieve?
The MLX90377GVE-ADB-330-TU is ISO 26262 ASIL-C capable for SENT output mode as a Safety Element out of Context (SEooC). It includes built-in diagnostics such as memory ECC, watchdog timers, and broken-wire detection on VDD/VSS. ASIL-B applies only to analog output - not relevant here since this variant is SENT-only.
Can the output mode of the MLX90377GVE-ADB-330-TU be reprogrammed in-system?
No - the output mode is factory-programmed and fixed per the option code ADB-330. SENT functionality is hardwired at production; it cannot be changed to analog, PWM, or SPC via end-user programming. Selecting the correct option code at order time is mandatory - no field reconfiguration is supported.
