Product details
Overview
MLX90377GGO-ADB-310-RE from Melexis is a monolithic Triaxis® Hall-based absolute position sensor IC for automotive and industrial rotary/linear sensing. It delivers 12-bit resolution analog and PWM outputs in High Speed Mode, operates from -40°C to +160°C, supports stray-field immune operation, and is ASIL-B capable for analog output. It serves as a non-contacting replacement for potentiometers in throttle and pedal position systems.
For engineers reviewing the MLX90377GGO-ADB-310-RE datasheet, pinout, applications, or equivalent options, key selection criteria include its TSSOP-16 dual-die package, programmable linear transfer characteristic (up to 32-piecewise), SENT/PWM/analog/SPC output flexibility, ISO 26262 ASIL-B qualification for analog mode, and robustness against stray magnetic fields in high-EMI environments.
Technical Context
The MLX90377GGO-ADB-310-RE integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling absolute angular (0–360°) or linear position decoding with appropriate magnet geometry. Its on-chip DSP performs real-time signal conditioning, including programmable piecewise-linearization and filtering.
This variant uses the TSSOP-16 package (dual-die configuration), supports Standard/Legacy Mode with Analog/PWM output in High Speed Mode (−310 option code), and features built-in reverse polarity and overvoltage protection. It requires no external programming for factory-configured output behavior and is not reprogrammable by end users.

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-310-RE | SOIC-8 single-die package; no electrical isolation between functional blocks; lower pin count; lacks dual-output redundancy | Suitable for cost-sensitive, non-redundant applications such as HVAC damper control or industrial valve positioning | Select when system-level ASIL-C redundancy is not required and board space permits SOIC-8 footprint |
| MLX90377GGO-ADB-330-RE | Same TSSOP-16 package but configured for SENT output (12-bit, SAE J2716 APR2016 compliant); higher protocol overhead; requires SENT decoder in host ECU | Preferred for OEMs standardizing on SENT bus infrastructure across powertrain ECUs | Select when host microcontroller has integrated SENT receiver and diagnostic message framing is required |
Compared with MLX90377GDC-ADB-310-RE, the MLX90377GGO-ADB-310-RE provides hardware-level redundancy and stray-field resilience essential for safety-critical throttle actuation; compared with MLX90377GGO-ADB-330-RE, it avoids SENT protocol dependencies while delivering deterministic analog/PWM timing for real-time control loops.

FAQ
What output protocols does the MLX90377GGO-ADB-310-RE support?
The MLX90377GGO-ADB-310-RE is factory-configured for Analog ratiometric and PWM output modes only. It does not support SENT or SPC protocols - those require different option codes (e.g., −330 or −380). The −310 suffix explicitly denotes High Speed Mode with Analog/PWM output, and this configuration cannot be changed post-manufacture.
Is the MLX90377GGO-ADB-310-RE pin-compatible with other MLX90377 variants in TSSOP-16?
Yes, all MLX90377 variants in the TSSOP-16 package (GO code) share identical pinout and footprint, including MLX90377GGO-ADB-310-RE, MLX90377GGO-ADB-330-RE, and MLX90377GGO-ADB-380-RE. Electrical functionality differs only in output protocol and NVRAM configuration - no PCB redesign is needed when switching between them.
Does the MLX90377GGO-ADB-310-RE require external programming for basic operation?
No, the MLX90377GGO-ADB-310-RE is fully functional upon power-up with factory-programmed parameters. No external programming tool, connector, or voltage sequencing is required for analog or PWM output. Programming via PTC (Programming through Connector) is optional and only needed for custom calibration or diagnostics - not for default operation.
What is the maximum allowable supply voltage for the MLX90377GGO-ADB-310-RE in PWM mode?
In PWM mode, the MLX90377GGO-ADB-310-RE supports up to 18 V supply voltage when powered directly from a vehicle battery. This is validated per Table 10's "Powered by vehicle battery (2)" condition. Operation above 5.5 V is restricted to PWM mode only; analog mode requires regulated 4.5–5.5 V supply.
How does the dual-die architecture of the MLX90377GGO-ADB-310-RE improve functional safety compliance?
The MLX90377GGO-ADB-310-RE's TSSOP-16 dual-die structure provides galvanic isolation (>4 MΩ) between two independent position sensing channels. This enables hardware redundancy for ASIL-C systems when paired with external voting logic - satisfying ISO 26262 requirements for fault detection without software-based duplication. Each die operates autonomously with separate VDD/VSS/VDEC rails.
