Product details
Overview
MLX90380LGO-BAC-000-TU from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, -40°C to 150°C operating temperature, and programmable X/Y magnetic axis for end-of-shaft configurations in brushless motor control systems.
For engineers reviewing the MLX90380LGO-BAC-000-TU datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die redundant resolver supports high-accuracy field-oriented control in automotive EPS, industrial servo drives, and PMSM/BLDC motor feedback loops requiring robust operation under thermal stress and EMI.
Technical Context
The MLX90380LGO-BAC-000-TU implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) and parallel (Z) magnetic field components on a single die, enabling precise angular computation from rotating permanent magnets without mechanical wear. Its dual-die TSSOP-16 architecture provides full hardware redundancy for ASIL-D–capable safety-critical systems.
Programmable sensitivity (40 mT full-scale range), selectable 3.3 V or 5 V supply, and configurable filter bandwidth (high/medium/low) allow optimization of ADC input utilization and dynamic response. Magnetic axis selection (X/Y) and ferrite magnet compatibility are factory-set per BAC-000 option code.

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LDC-BAC-000-RE | SOIC-8 single-die variant with identical BAC-000 option (ferrite magnet, X/Y axis, 40 mT range) | Lacks dual-die redundancy; suitable for non-safety-critical BLDC fans or pumps where cost and footprint are prioritized | Select when functional safety certification is not required and PCB space is constrained. |
| MLX90380LGO-BAA-000-RE | TSSOP-16 dual-die variant with BAA-000 option (SmCo magnet, X/Y axis, 40 mT range) | Higher temperature stability (SmCo TCS ~350 ppm/°C vs. ferrite's ~2000 ppm/°C); suited for precision aerospace or test equipment | Choose when long-term angular stability across wide temperature gradients outweighs cost sensitivity. |
Compared with MLX90380LGO-BAC-000-TU, the SOIC-8 alternative trades redundancy for size and cost, while the SmCo-based TSSOP-16 variant improves thermal drift at the expense of magnet material cost - making MLX90380LGO-BAC-000-TU the optimal balance for cost-conscious automotive EPS and industrial servo designs requiring ASIL-D readiness.

FAQ
What magnetic axis configuration is implemented in MLX90380LGO-BAC-000-TU?
The MLX90380LGO-BAC-000-TU uses the X/Y magnetic axis configuration, as defined by its BAC-000 option code. This enables equal sensitivity along the X and Y axes and is optimized for end-of-shaft mounting with a single-pole rotating magnet. The device outputs OUT1 as COS and OUT2 as SIN relative to this X/Y plane, supporting direct arctangent computation for absolute angle determination.
Does MLX90380LGO-BAC-000-TU support both 3.3 V and 5 V supply rails?
Yes, MLX90380LGO-BAC-000-TU supports dual supply operation: 3.135–3.6 V on VDD3V3 pins and 4.5–5.5 V on VDD5V pins. For 5 V operation, the VDD3V3 pins must be left floating per datasheet guidance. Both supply domains power independent dies in the TSSOP-16 package, allowing flexible integration with mixed-voltage MCU platforms.
How does the dual-die architecture of MLX90380LGO-BAC-000-TU enhance functional safety?
The MLX90380LGO-BAC-000-TU integrates two fully independent sensor dies in one TSSOP-16 package, each with dedicated power, ground, and analog outputs. This enables lockstep comparison, cross-die fault detection, and diagnostic coverage required for ASIL-D compliance per ISO 26262. Redundancy is implemented at the silicon level - no external components or PCB routing duplication is needed.
What is the full-scale magnetic range of MLX90380LGO-BAC-000-TU and which magnet type does it target?
The MLX90380LGO-BAC-000-TU has a factory-programmed full-scale magnetic range of 40 mT, corresponding to the "000" suffix in its BAC-000 option code. It is calibrated for use with ferrite magnets, as indicated by the "C" in BAC. This combination delivers cost-effective, thermally robust position sensing for automotive and industrial applications where SmCo or NdFeB magnets are unnecessary.
Can MLX90380LGO-BAC-000-TU be used in through-shaft configurations?
No - the MLX90380LGO-BAC-000-TU is configured for X/Y magnetic axis operation, which is specified for end-of-shaft (on-axis) mounting with two-pole magnets. Through-shaft (off-axis) configurations require Z/Y or X/Z axis variants (e.g., BAB or BAA codes with "x2x" or "x3x" suffixes). Using MLX90380LGO-BAC-000-TU in through-shaft setups will result in degraded sensitivity and angular accuracy.
