Overview
MLX90377GVE-ADB-300-SP from Melexis is a monolithic Triaxis® Hall-based magnetic position sensor IC for absolute rotary or linear position sensing. It delivers 12-bit ratiometric analog and PWM outputs in Standard/Legacy Mode, operates from -40°C to 160°C, supports stray-field immune configurations, and is qualified for automotive ASIL-B safety integrity in analog mode.
For engineers reviewing the MLX90377GVE-ADB-300-SP datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SMP-3), confirmed output modes (analog/PWM, low-power), functional safety classification (ASIL-B), magnetic field tolerance (±1 T), and real-world use cases including throttle and pedal position sensing.
Technical Context
The MLX90377GVE-ADB-300-SP integrates a Triaxis® Hall front end sensitive to Bx, By, and Bz magnetic components, enabling robust absolute angle or linear displacement decoding without mechanical contact. Its on-chip DSP performs real-time signal conditioning, piecewise-linearization (4/8/16/32 points), and programmable transfer characteristics.
This variant uses SMP-3 packaging (PCB-less single mold), supports only analog and PWM output protocols (not SENT or SPC), and is configured for Standard/Legacy Mode with low-power operation. It implements reverse polarity and overvoltage protection, internal analog/digital regulators, and temperature compensation across its full operating range.

FAQ
What output protocols does the MLX90377GVE-ADB-300-SP support?
The MLX90377GVE-ADB-300-SP supports only analog ratiometric voltage and PWM output modes, as defined by its ADB-300 option code. SENT and SPC protocols are not enabled in this variant and cannot be activated via programming. This fixed configuration ensures deterministic behavior for safety-critical throttle and pedal applications where protocol stability is essential.
Is the MLX90377GVE-ADB-300-SP pin-compatible with other MLX90377 package variants?
No-the MLX90377GVE-ADB-300-SP uses the SMP-3 package with three main terminals (VDD, OUT, VSS) and two test pads (INPUT, TEST), differing physically and electrically from SOIC-8, TSSOP-16, or DMP-4 variants. Direct PCB replacement is not possible without layout revision, though functional equivalence exists within the same option code family.
Does the MLX90377GVE-ADB-300-SP require external decoupling capacitors?
No-SMP-3 packaging integrates internal decoupling capacitance, eliminating the need for external VDD/VDEC capacitors. This reduces bill-of-materials count and PCB area, while maintaining stable operation across temperature and supply variations as validated in Melexis' application diagrams (Section 16.4).
What is the functional safety qualification status of the MLX90377GVE-ADB-300-SP?
The MLX90377GVE-ADB-300-SP is ISO 26262 ASIL-B capable in analog output mode and classified as a Safety Element out of Context (SEooC). Its diagnostic coverage, fault handling time interval (<100 ms), and hardware metrics (SPFM >90%) are documented in the official safety manual (Rev. 003, Section 15), supporting integration into ASIL-B automotive systems.
Can the MLX90377GVE-ADB-300-SP be reprogrammed in-system for different transfer characteristics?
Yes-the MLX90377GVE-ADB-300-SP supports end-user programming of its transfer characteristic (4/8/16/32-point PWL), filtering, and diagnostics via the Programming through Connector (PTC) interface. However, output protocol (analog/PWM only) and magnetic mode (Standard/Legacy) are permanently fixed by the ADB-300 option code and cannot be altered post-manufacture.
