Product details
Overview
MLX90380LGO-BAA-000-SP from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, -40°C to 150°C operating temperature, and support for end-of-shaft or through-shaft magnet configurations using SmCo magnets and X/Y magnetic axis alignment.
For engineers reviewing the MLX90380LGO-BAA-000-SP datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die fully redundant resolver provides high-accuracy rotor angle feedback in demanding BLDC motor control, field-oriented control, and automotive EPS systems where functional safety and thermal robustness are critical.
Technical Context
The MLX90380LGO-BAA-000-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) magnetic field components on two independent dies, enabling true 360° absolute angle computation without interpolation. Its dual-die architecture delivers full redundancy for ASIL-B/C applications.
It supports factory-programmed 40 mT full-scale magnetic range, SmCo magnet compatibility, and X/Y axis configuration - with ratiometric analog outputs referenced to VDD (3.3 V or 5 V), programmable bandwidth (low/medium/high), and internal chopping at 1 MHz for noise immunity.
Key Specifications

| Output Refresh Rate | 4 µs per field component (8 µs total for both SIN/COS); supports >25,000 rpm mechanical speed |
| Operating Voltage | 3.135–3.6 V or 4.5–5.5 V; dual supply pins (VDD3V3/VDD5V) allow single-rail operation |
| Temperature Range | -40°C to +150°C; qualified for under-hood automotive and industrial motor drive environments |
| Magnetic Range | 40 mT full-scale (BAA-000 option); optimized for SmCo magnets in end-of-shaft configurations |

| Package | TSSOP-16; dual-die layout with separate ground and supply pins per die for redundancy isolation |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A and Die B each have independent power, ground, test, and analog output pins - enabling fault detection and fail-operational capability in safety-critical systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns per die; mandatory for redundancy integrity and EMC performance |
| 5, 13 | OUT2_B / OUT2_A | Sine analog outputs from Die B and Die A; used for cross-checking or voting logic |
| 8, 16 | OUT1_B / OUT1_A | Cosine analog outputs from Die B and Die A; paired with respective OUT2 for arctan calculation |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs per die; must be decoupled individually for fault containment |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs per die; left floating when using 5 V mode per datasheet guidance |
| 4, 11 | TEST_A / TEST_B | Factory test pins; recommended tied to GND for optimal EMC in final design |
| 2, 3, 10, 12 | NC | No-connect pins; must be connected to GND per datasheet for EMC compliance |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar resolver sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LDC-BAA-000-RE | SOIC-8 single-die variant; identical magnetic specs and programming but no hardware redundancy | Suitable for non-safety-critical BLDC fans or pumps where cost and board space constrain TSSOP-16 use | Select when ASIL compliance is not required and PCB area is limited |
| MLX90380LGO-BAB-000-RE | Same TSSOP-16 package but NdFeB magnet calibration; 10 mT–70 mT sensitivity range vs. fixed 40 mT for SmCo | Used in through-shaft or off-axis configurations requiring higher magnetic field tolerance | Choose for NdFeB magnet systems needing wider dynamic range and lower material cost |
Compared with MLX90380LGO-BAA-000-SP, the SOIC-8 alternative sacrifices redundancy for compactness, while the BAB-000 variant trades SmCo-specific stability for broader magnetic field adaptability - making the BAA-000 TSSOP-16 optimal for safety-critical, thermally aggressive end-of-shaft deployments.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAA-000-SP?
The MLX90380LGO-BAA-000-SP is factory-programmed for X/Y magnetic axis configuration, meaning it measures orthogonal in-plane magnetic field components (BX and BY) - optimized for end-of-shaft applications with SmCo magnets. This configuration delivers equal sensitivity on both axes and supports true 360° angle computation without interpolation. The BAA-000 option code explicitly defines this X/Y alignment per Melexis ordering documentation.
Does MLX90380LGO-BAA-000-SP support both 3.3 V and 5 V operation?
Yes, MLX90380LGO-BAA-000-SP supports dual-supply operation: 3.135–3.6 V on VDD3V3 pins and 4.5–5.5 V on VDD5V pins. The device uses only one supply rail at a time - VDD3V3 must be left floating during 5 V operation, and vice versa - as specified in section 13 of the datasheet. Both supply domains are present on the TSSOP-16 package to maintain redundancy integrity across power domains.
How does the dual-die architecture of MLX90380LGO-BAA-000-SP enable functional safety?
The MLX90380LGO-BAA-000-SP implements physically isolated Die A and Die B within the TSSOP-16 package, each with independent VSS, VDD, TEST, and analog output pins. This separation allows cross-die comparison of sine/cosine outputs for fault detection, supporting ASIL-B/C diagnostic coverage. Redundancy is enforced at the silicon and package level - not just signal processing - making MLX90380LGO-BAA-000-SP suitable for ISO 26262-compliant EPS and traction systems.
What is the output update timing behavior of MLX90380LGO-BAA-000-SP?
MLX90380LGO-BAA-000-SP delivers sequential field component measurements: each of the two orthogonal outputs (OUT1/COS and OUT2/SIN) updates every 4 µs, resulting in a full sine/cosine pair every 8 µs. This 125 kHz Nyquist frequency supports mechanical speeds up to 25,000 rpm. Tracking delay varies with programmed bandwidth - 12 µs (high), 29.5 µs (medium), or 74 µs (low) - as defined by the option code's third digit per Table 2.
Can MLX90380LGO-BAA-000-SP be used with ferrite or NdFeB magnets?
No - MLX90380LGO-BAA-000-SP is specifically calibrated for samarium-cobalt (SmCo) magnets, as indicated by the "BAA" option code prefix. Using ferrite (BAC) or NdFeB (BAB) magnets would cause significant sensitivity mismatch and temperature drift due to differing flux-temperature coefficients. For those magnet types, select MLX90380LGO-BAC-xxx-SP or MLX90380LGO-BAB-xxx-SP variants instead, which are factory-programmed with appropriate TCS and offset compensation.
