Product details
Overview
MLX90333LDC-BCH-000-RE from Melexis is a Triaxis® 3D contactless position sensor IC in SOIC-8 package, delivering 12-bit angular resolution, ratiometric analog or PWM output, and programmable transfer characteristics (Alpha/Beta) for joystick, linear stroke, and rotary sensing. It measures BX, BY, and BZ magnetic field components using integrated magneto-concentrator (IMC) and Hall plates, operating across –40 °C to +150 °C.
For engineers reviewing the MLX90333LDC-BCH-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, real-world use cases in man-machine interfaces, and validated alternative options for 3D magnetic position sensing.
Technical Context
The MLX90333LDC-BCH-000-RE integrates a 16-bit RISC microcontroller (5 MIPS @ 20 MHz), dual 15-bit ADCs for raw X/Y/Z field measurement, and on-chip DSP performing CoRDiC-based rectangular-to-polar conversion. Its Triaxis® architecture uses an IMC for BX/BY detection and a conventional Hall plate for BZ, enabling true 3D vector sensing without external magnets or complex PCB layouts.
It supports three output modes - ratiometric analog, PWM (100–1000 Hz), or 3-wire SPI - with full end-of-line programmability of offset, gain, clamping, dead zone, and thermal drift compensation via PTC-04 programmer. The SOIC-8 variant (BCH-000) implements single-die architecture with OUT1/OUT2 outputs and VDD/VSS/VDIG pins, excluding redundant TSSOP-16 features like dual-die isolation or /SS2/SCLK2.

Pinout & Package
MLX90333LDC-BCH-000-RE is housed in a RoHS-compliant SOIC-8 package (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is VDD; pins 2 and 8 are ground (VSS); pin 7 is VDIG (digital supply); pins 5 and 4 provide OUT1 and OUT2 respectively; pin 3 is NC; pin 6 is Test 1. Unused test pins must be grounded per EMC recommendations.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VDD | Analog power supply input (4.5–5.5 V); powers internal regulator and analog front-end |
| 2 | VSS | Analog ground reference; must be connected to system ground with low-impedance path |
| 3 | NC | No connection; internally unconnected; recommended to tie to VSS for EMC stability |
| 4 | OUT2 | Secondary output: configurable as analog, PWM, or diagnostic signal per programming |
| 5 | OUT1 | Primary output: default channel for Alpha angle or X-axis position in joystick mode |
| 6 | Test 1 | Factory test pin; not functional in end application; tie to VSS per datasheet EMC guidance |
| 7 | VDIG | Digital supply rail; decoupled separately from VDD to reduce digital noise coupling into analog path |
| 8 | VSS | Second analog ground pin; used for Kelvin sensing or low-noise return path |

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-BCH-000-RE | Dual-die TSSOP-16 package with full redundancy, isolation resistance >4 MΩ, extended diagnostics; higher current draw (2×). | Required for ASIL-B automotive safety-critical systems; unsuitable for space-constrained SOIC-8 footprints. | Select when functional safety compliance (ISO 26262) and fault-tolerant operation are mandatory. |
| AS5055A-DSOT | Single-axis Hall-based encoder; no IMC, no BZ sensing; 12-bit resolution but only 2D capability; SPI-only interface. | Limited to rotary or linear single-axis use; lacks joystick or 3D vector output flexibility. | Choose for cost-sensitive, single-degree-of-freedom applications where Triaxis® 3D capability is unnecessary. |
Compared with MLX90333LDC-BCH-000-RE, the MLX90363KGO-BCH-000-RE adds hardware redundancy and safety features at the cost of size and power, while the AS5055A-DSOT offers lower integration and reduced magnetic dimensionality-making the MLX90333LDC-BCH-000-RE optimal for compact, programmable 3D position sensing in industrial and automotive HMI.

FAQ
What is the maximum operating temperature supported by the MLX90333LDC-BCH-000-RE?
The MLX90333LDC-BCH-000-RE is rated for operation from –40 °C to +150 °C, matching the 'L' temperature grade defined in its ordering code. This specification is validated per AEC-Q100 stress testing and applies to continuous operation under specified electrical conditions, including 5 V supply and load currents up to ±20 mA per output.
Does the MLX90333LDC-BCH-000-RE support SPI communication in its SOIC-8 package?
No, the MLX90333LDC-BCH-000-RE (SOIC-8, BCH option code) does not support SPI communication. SPI functionality requires the BCT option code and TSSOP-16 package (e.g., MLX90333LGO-BCT-000-RE), which provides dedicated MOSI/MISO/SCLK pins. The SOIC-8 variant supports only analog and PWM outputs.
How is the MLX90333LDC-BCH-000-RE calibrated for custom transfer characteristics?
The MLX90333LDC-BCH-000-RE is calibrated using Melexis' PTC-04 programming unit, which communicates exclusively through VDD-VSS-OUT pins. End-of-line calibration programs Alpha/Beta parameters-including slope, discontinuity point, dead zone, and clamping-into on-chip EEPROM, enabling field-specific linearization without modifying hardware.
What magnetic field strength range is required for reliable operation of the MLX90333LDC-BCH-000-RE?
The MLX90333LDC-BCH-000-RE requires ≥20 mT in BX or BY (via IMC) and ≥24 mT in BZ (via Hall plate) for nominal operation. Maximum usable field is ±70 mT (XY) and ±140 mT (Z); above 70 mT, IMC saturation increases linearity error. Field amplitude must remain within these bounds across the full temperature range.
Can the MLX90333LDC-BCH-000-RE be used in safety-critical automotive applications?
The MLX90333LDC-BCH-000-RE meets AEC-Q100 Grade 0 qualification and includes diagnostics (broken VDD/VSS detection, output clamping), but lacks hardware redundancy. For ASIL-B/C applications, Melexis recommends the dual-die MLX90363KGO-BCH-000-RE, which provides isolated die pairs and certified safety mechanisms not present in the single-die MLX90333LDC-BCH-000-RE.
