Product details
Overview
MLX90378GGO-ABJ-300-SP from Melexis is a Triaxis® 3D magnetic position processor IC for non-contacting absolute angle sensing in joysticks and shift levers. It integrates a Triaxis® Hall front end, DSP-based signal conditioning, dual 12-bit PWM or SENT outputs, ISO26262 ASIL-C safety compliance, and operates from -40°C to +160°C with 4.5–5.5 V supply.
For engineers reviewing the MLX90378GGO-ABJ-300-SP datasheet, pinout, applications, or equivalent options, this device supports programmable linear transfer characteristics (4-point per axis), external input measurement, SENT SAE J2716 APR2016 compliance, and redundant dual-die TSSOP-16 packaging for automotive-grade functional safety.
Technical Context
The MLX90378GGO-ABJ-300-SP implements a dual-die TSSOP-16 architecture with galvanic isolation (≥4 MΩ between dice) and independent analog/digital ground paths. Its Triaxis® sensor measures Bx, By, and Bz components simultaneously, enabling robust 3D angular decoding without mechanical wear.
It supports two real-time output modes: continuous asynchronous acquisition (600–846 µs angle measurement period) for PWM or pause-less SENT, and continuous synchronous acquisition synchronized to SENT frame timing (846–1110 µs frame periods). The internal 24 MHz main clock has ±2% thermal drift and enables <17 µs latency in synchronous mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3D magnetic position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90363GGO-ABG-000-SP | Single-die TSSOP-16; no galvanic isolation; SENT-only output; no external INPUT pin | Lacks ASIL-C SEooC certification and dual-output flexibility; suitable for cost-sensitive non-safety systems | Select when functional safety is not required and only single-channel SENT output suffices |
| AMS AS5055A-BQFT | Single-die QFN-24; SPI/I²C interface only; no native SENT/PWM; 10-bit resolution | Requires external MCU for protocol translation and diagnostics; limited to lower-temperature industrial use (-40°C to +125°C) | Select when board space is constrained and host MCU handles signal processing and safety monitoring |
Compared with MLX90378GGO-ABJ-300-SP, the MLX90363 offers reduced cost and complexity but forfeits redundancy and safety certification, while the AS5055A requires external firmware development and lacks integrated output drivers-making MLX90378GGO-ABJ-300-SP the only solution combining dual-die isolation, ASIL-C, and native dual-PWM/SENT in a single TSSOP-16 package.

FAQ
What is the primary sensing architecture used in the MLX90378GGO-ABJ-300-SP?
The MLX90378GGO-ABJ-300-SP uses Melexis' proprietary Triaxis® Hall technology, which integrates three orthogonal Hall plates on a single silicon die to measure the Bx, By, and Bz components of magnetic flux density simultaneously. This enables true 3D position decoding without mechanical contact or moving parts, and is fundamental to the MLX90378GGO-ABJ-300-SP's ability to deliver absolute angular output in joystick and lever applications.
Does the MLX90378GGO-ABJ-300-SP support both PWM and SENT output simultaneously?
No, the MLX90378GGO-ABJ-300-SP supports either dual PWM outputs or a single SENT output with two encoded channels-not both simultaneously. Output mode is selected via the PROTOCOL parameter during programming; SENT mode allows transmission of angle data plus diagnostics or external INPUT measurements in a single frame, while PWM mode delivers two independent 12-bit pulse-width modulated signals optimized for direct MCU capture.
What safety standard compliance does the MLX90378GGO-ABJ-300-SP provide, and how is it implemented?
The MLX90378GGO-ABJ-300-SP is certified as an ISO26262 ASIL-C Safety Element out of Context (SEooC). It implements hardware-level diagnostics including temperature monitoring, magnetic field strength validation, PWM output integrity checks, NVRAM BIST, and watchdog timers (IWD/AWD), all documented in Melexis' functional safety manual. These mechanisms are intrinsic to the MLX90378GGO-ABJ-300-SP silicon and require no external components to meet ASIL-C decomposition requirements.
How is redundancy achieved in the MLX90378GGO-ABJ-300-SP package variant?
Redundancy in the MLX90378GGO-ABJ-300-SP is achieved through its dual-die TSSOP-16 implementation: two functionally identical MLX90378 dies are monolithically integrated in one package, electrically isolated with ≥4 MΩ resistance between dice. Each die has independent VDD, VSS (analog/digital), VDEC, and output pins-allowing independent operation, cross-checking, or fail-operational fallback without shared failure modes.
Can the MLX90378GGO-ABJ-300-SP be programmed in-system, and what parameters are user-configurable?
Yes, the MLX90378GGO-ABJ-300-SP supports in-system programming via its SENT or PWM interface using Melexis' PTM (Programmable Triaxis® Module) protocol. Users can configure output protocol (PWM/SENT), angular calculation formula, 4-point linearization parameters per axis, discontinuity point, clamping limits, external INPUT mapping, filter coefficients (IIR/FIR), and diagnostic thresholds-all stored in on-chip NVRAM and retained across power cycles.
