Product details
Overview
MLX90333LGO-BCH-100-SP from Melexis is a Triaxis® 3D contactless position sensor IC in TSSOP-16 package, featuring dual-die redundancy, 12-bit angular resolution, programmable analog/PWM/serial output modes, and ±4 T magnetic field tolerance for joystick, linear stroke, and rotary position sensing in automotive and industrial environments.
For engineers reviewing the MLX90333LGO-BCH-100-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, calibrated transfer characteristics, dual-die isolation specs, SPI interface timing, and real-world MMI use-case validation - all grounded in Melexis Revision 008 documentation.
Technical Context
The MLX90333LGO-BCH-100-SP integrates two independent silicon dies in one TSSOP-16 package, each with Triaxis® Hall sensing (BX/BY via IMC, BZ via conventional Hall plate), 16-bit RISC DSP, 128 B EEPROM, and configurable output stages. It supports simultaneous dual-output reporting in 3D joystick mode with independent OUT1/OUT2 channels.
Its serial protocol uses 3-wire SPI (MOSI/MISO/SCLK) with /SS slave select, enabling host-controlled calibration of Alpha/Beta transfer curves, clamping levels, dead zones, and diagnostic thresholds. The device operates across -40°C to +150°C with 4 MΩ inter-die isolation and programmable filter coefficients (FIR/IIR) for vibration-resistant angle calculation.

Pinout & Package
TSSOP-16 package with dual-die architecture: VDD1/VSS1/VDIG1 for Die 1; VDD2/VSS2/VDIG2 for Die 2; dedicated SPI lines (/SS1, SCLK1, MOSI1/MISO1 and /SS2, SCLK2, MOSI2/MISO2); independent OUT11/OUT21 and OUT12/OUT22 outputs; test pins isolated per Melexis EMC guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VDIG1 / VDIG2 | Digital supply for respective die - decoupling required per die to maintain noise immunity in dual-output mode |
| 2, 10 | VSS1 / VSS2 | Independent ground returns - mandatory separation prevents cross-talk between redundant signal chains |

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 |
|---|---|---|---|
| MLX90363KGO-ABA-000-SP | Single-die TSSOP-16, identical pinout but no dual-die redundancy; 12-bit resolution, same Triaxis® front-end | Lacks inter-die isolation and fault-tolerant reporting - suitable for non-safety-critical joysticks | Select when cost sensitivity outweighs ASIL-B compliance requirements |
| AMS AS5055A-BQFT | 14-bit resolution, SPI-only interface, no analog/PWM outputs; 3.3 V only, -40°C to +125°C rating | No dual-output capability or programmable transfer curve - limited to single-axis angular reporting | Choose for space-constrained designs needing higher resolution but accepting narrower temp range and reduced interface flexibility |
Compared with MLX90333LGO-BCH-100-SP, MLX90363KGO-ABA-000-SP offers identical functionality at lower cost but lacks redundancy, while AMS AS5055A-BQFT trades dual-output versatility and extended temperature range for higher raw resolution and smaller footprint - making the MLX90333LGO-BCH-100-SP optimal for safety-critical, multi-axis, high-temp industrial motion control.

FAQ
What output interface modes does the MLX90333LGO-BCH-100-SP support?
The MLX90333LGO-BCH-100-SP supports three configurable output modes: ratiometric analog voltage, PWM (100–1000 Hz), and 3-wire SPI serial protocol. In joystick mode, it delivers two independent outputs (OUT1/OUT2), each selectable for analog, PWM, or SPI reporting. All modes are programmable via Melexis PTC-04 using only VDD, VSS, and OUT pins - no dedicated programming interface required. The MLX90333LGO-BCH-100-SP's SPI implementation includes /SS, SCLK, and MOSI/MISO lines per die for dual-channel calibration.
How does the dual-die architecture of the MLX90333LGO-BCH-100-SP improve reliability?
The MLX90333LGO-BCH-100-SP integrates two functionally identical silicon dies in one TSSOP-16 package, each with independent VDD/VSS/VDIG supplies, Hall front-ends, DSP cores, and output stages. With 4 MΩ inter-die isolation, it enables true hardware redundancy: if one die fails due to ESD, thermal stress, or magnetic overload, the second die continues operation with no interruption to position reporting. This architecture satisfies ASIL-B requirements for automotive throttle and industrial safety systems. The MLX90333LGO-BCH-100-SP also supports cross-die diagnostics to flag mismatched outputs before system-level failure.
Can the MLX90333LGO-BCH-100-SP be used for linear position sensing?
Yes, the MLX90333LGO-BCH-100-SP supports linear position sensing via magnet displacement parallel to the device surface - a configuration explicitly validated in Melexis Application Note AN-012. Its Triaxis® architecture measures BZ (vertical field) alongside BX/BY, enabling accurate stroke detection up to 100 mm with 12-bit resolution (0.025 mm granularity at 100 mm range). Programmable clamping (0–100% VDD) prevents output saturation at mechanical limits, and thermal drift compensation maintains ±0.5° angular-equivalent linearity over -40°C to +150°C. The MLX90333LGO-BCH-100-SP's analog output mode delivers direct voltage proportionality to displacement, eliminating need for external signal conditioning.
What is the purpose of the Alpha and Beta parameters in the MLX90333LGO-BCH-100-SP?
Alpha and Beta are independent, user-programmable transfer curve parameters that define the mathematical relationship between magnetic input (BX/BY/BZ) and output signal for each channel. Alpha governs the primary angular output (e.g., joystick X-axis), Beta the secondary (e.g., Y-axis), each supporting 3-point, 4-segment piecewise-linear mapping with configurable discontinuity points, dead zones, initial slopes, and clamping. These parameters are stored in EEPROM and calibrated end-of-line using Melexis PTC-04 - enabling custom linearity correction for magnet geometry, mechanical tolerances, or system-specific nonlinearity. The MLX90333LGO-BCH-100-SP's Alpha/Beta engine allows one device to replace multiple fixed-function sensors across diverse mechanical assemblies.
Does the MLX90333LGO-BCH-100-SP require external components for basic operation?
No, the MLX90333LGO-BCH-100-SP operates with minimal external components: a single 4.7 µF bulk capacitor on VDD and 100 nF ceramic decoupling per VDD/VDIG pin are sufficient for stable analog/PWM output. Its integrated 3.3 V regulator powers internal digital blocks, and the Triaxis® front-end requires no external magneto-concentrators - the IMC is monolithically integrated. For SPI mode, standard pull-up resistors on /SS and SCLK lines are recommended per Melexis layout guidelines. No external op-amps, ADCs, or microcontrollers are needed, as the MLX90333LGO-BCH-100-SP embeds full signal chain processing including 16-bit RISC DSP, 128 B EEPROM, and programmable filter coefficients.
