Product details

Overview

MLX90333LGO-BCH-001-TU from Melexis is a Triaxis® 3D contactless position sensor IC in TSSOP-16 package, featuring dual-die redundancy, 12-bit angular resolution, ratiometric analog/PWM/serial (3-wire SPI) output modes, and programmable transfer characteristics for joystick, linear stroke, and rotary position sensing in automotive and industrial HMI systems.

For engineers reviewing the MLX90333LGO-BCH-001-TU datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions for TSSOP-16 dual-die configuration, calibrated accuracy specs across -40°C to +150°C, and real-world selection guidance against functionally comparable alternatives.

Technical Context

The MLX90333LGO-BCH-001-TU integrates two independent silicon dies in one TSSOP-16 package, each with Triaxis® Hall sensing (BX/BY via IMC, BZ via conventional Hall plate), 15-bit ADC front-end, 16-bit RISC DSP, and EEPROM for end-of-line calibration of alpha/beta transfer curves, clamping, dead zone, and filtering. It supports full redundancy with isolated VDD/VSS/VDIG per die and separate SPI interfaces (MOSI1/MISO1/SCLK1 and MOSI2/MISO2/SCLK2).

Its dual-die architecture enables fault-tolerant operation: diagnostics include broken VDD/VSS detection, field threshold monitoring, and configurable watchdog timing (5 ms). Output modes are independently configurable per die-ratiometric analog, PWM (100–1000 Hz), or SPI-with programmable polarity, frequency, and saturation levels (e.g., Vsat_lo = 3%VDD, Vsat_hi = 96%VDD).

Key Specifications

Parameter	Value and Actual Design Meaning

Angular Resolution	12 bits (0.088°/LSB theoretical, noise-limited effective resolution ~10 bits)
Magnetic Input Range	BX/BY: 20–70 mT; BZ: 24–140 mT; ±4 T absolute max (prevents saturation-induced linearity error)
Output Options	Dual independent outputs: ratiometric analog (0–100%VDD), PWM (100–1000 Hz), or 3-wire SPI (16-bit position data)
Supply & Current	VDD = 4.5–5.5 V; IDD = 13.5 mA typical (fast mode, per die); dual-die draws ~27 mA total
Accuracy (Thermal)	10-bit angular thermal accuracy (±0.3° typical over full temp range, per die)
Isolation Resistance	4 MΩ between dice (validates functional safety separation for ASIL-B compliance paths)

Pinout & Package

TSSOP-16 package with dual-die redundancy: physically isolated power/ground domains (VDD1/VSS1/VDIG1 and VDD2/VSS2/VDIG2), separate SPI interfaces, and independent OUT1/OUT2 output stages. Unused pins (e.g., Pin 13 "Not Used") must be grounded per EMC recommendation.

Pin/Terminal	Circuit Role	Design Meaning
1, 11	VDIG1 / VDD2	Digital supply for Die 1 / Power supply for Die 2 - decoupling required per die
2, 10	VSS1 / VSS2	Ground return for Die 1 / Ground return for Die 2 - isolated reference planes
3, 12	VDD1 / Test 02	Power supply for Die 1 / Factory test pin - connect to ground if unused
4, 14	Test 01 / OUT21	Factory test pin / PWM/analog output channel 2 for Die 1
5, 15	/SS / MOSI1/MISO1	Slave select for Die 1 SPI / Bidirectional serial data for Die 1
6, 16	OUT2 / Test 11	PWM/analog output channel 2 for Die 2 / Factory test pin
7	OUT12	Analog/PWM output channel 1 for Die 2 - independent of Die 1's OUT1
8	VSS (Ground)	Common mechanical ground pad - ties both die grounds externally
9	VDIG2	Digital supply for Die 2 - routed separately from VDIG1 for noise isolation

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3D magnetic position sensor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90363KGO-ABB-000-TU	Single-die TSSOP-16, same Triaxis® core but no redundancy; 12-bit resolution, -40°C to +125°C rating	Lacks dual-die isolation and inter-die diagnostics; unsuitable for ASIL-B systems requiring hardware redundancy	Select when cost sensitivity outweighs functional safety requirements and temperature range ≤125°C suffices.
AMS AS5055A-BQFT	Single-die 3D Hall sensor in QFN-24; 14-bit resolution, SPI-only output, -40°C to +125°C	No analog/PWM outputs; no end-of-line programmability for transfer curves; lower magnetic sensitivity (BX/BY: 10–50 mT)	Choose for space-constrained PCBs needing high-resolution SPI data only, without analog interface or field-programmable calibration.

Compared with MLX90333LGO-BCH-001-TU, the MLX90363 offers identical sensing architecture at lower cost but sacrifices redundancy and extended temperature capability, while the AS5055A provides higher raw resolution in smaller form factor but lacks analog outputs, programmable clamping, and dual-die fault tolerance.

FAQ

What is the operating temperature range of the MLX90333LGO-BCH-001-TU?

The MLX90333LGO-BCH-001-TU is qualified for -40°C to +150°C ambient operation (L-grade), validated per AEC-Q100 with full electrical specification coverage across this range. Its dual-die architecture maintains functional integrity at extreme temperatures, making it suitable for under-hood automotive applications such as throttle and pedal position sensing where thermal stability is critical. The device's 10-bit angular thermal accuracy holds across the full span.

How does the dual-die redundancy in MLX90333LGO-BCH-001-TU improve system safety?

The MLX90333LGO-BCH-001-TU implements true hardware redundancy: two physically isolated silicon dies share one TSSOP-16 package but feature independent VDD/VSS/VDIG supplies, separate SPI interfaces (MOSI1/MISO1/SCLK1 and MOSI2/MISO2/SCLK2), and uncorrelated sensing paths. This enables cross-die comparison for fault detection, meets ASIL-B decomposition requirements, and provides fail-operational capability when paired with appropriate host MCU logic. Inter-die isolation resistance is guaranteed at ≥4 MΩ.

Can MLX90333LGO-BCH-001-TU output both analog and SPI signals simultaneously?

No - MLX90333LGO-BCH-001-TU supports only one active output mode per die at a time: either ratiometric analog, PWM, or SPI. However, each die can be configured independently (e.g., Die 1 in analog mode, Die 2 in SPI mode), enabling simultaneous delivery of two different output types. Configuration is stored in EEPROM and set via Melexis PTC-04 programmer using VDD-VSS-OUT pins - no external microcontroller required for calibration.

What magnetic field strength is required for reliable operation of MLX90333LGO-BCH-001-TU?

The MLX90333LGO-BCH-001-TU requires BX/BY ≥20 mT and BZ ≥24 mT for nominal operation, with optimal linearity up to 70 mT (BX/BY) and 140 mT (BZ). Its Integrated Magneto-Concentrator (IMC) provides 1.2–1.8× gain on horizontal fields, allowing use with small, low-cost magnets. Field thresholds (FIELDTHRES_LOW/HIGH) are user-programmable to reject noise or detect magnet presence/absence - critical for tamper-proof HMI designs.

Is MLX90333LGO-BCH-001-TU pin-compatible with other MLX90333 variants?

MLX90333LGO-BCH-001-TU uses the TSSOP-16 package and shares pinout compatibility with all GO-code variants (e.g., MLX90333KGO-BCH-000-TU), including identical pin functions for VDD/VSS/VDIG/OUT1/OUT2/SPI lines. However, it is not pin-compatible with DC-code SOIC-8 variants due to differing pin count (8 vs. 16) and dual-die routing. Always verify package code (GO = TSSOP-16 dual-die) and option code (BCH-001 = SPI-enabled) before substitution.
