Product details
Overview
MLX90380LGO-BAA-000-TU from Melexis is a dual-die, fully redundant Triaxis® resolver IC delivering true 360° sine/cosine analog outputs for absolute rotary position sensing. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, achieves 4µs output refresh rate, and is configured for X/Y magnetic axis with SmCo magnet compatibility and 40mT full-scale range. It serves as the core angular transducer in safety-critical motor control systems requiring functional redundancy.
For engineers reviewing the MLX90380LGO-BAA-000-TU datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, TSSOP-16 package mapping, magnetic axis configuration details, real-world angular error performance, and validated alternative options for automotive and industrial BLDC/PMSM systems.
Technical Context
The MLX90380LGO-BAA-000-TU implements dual independent die in a single TSSOP-16 package, each with dedicated VDD/VSS/OUT/TEST pins, enabling hardware-level redundancy for ASIL-D capable systems. Its Triaxis® Hall architecture simultaneously measures orthogonal (X/Y) magnetic field components using on-chip spinning current and chopper stabilization at 1 MHz.
Output signals are ratiometric analog voltages (OUT1 = COS, OUT2 = SIN), updated every 4 µs with ≤12 µs tracking delay under high-bandwidth programming. Sensitivity is factory-programmed to 1 %VDD/mT for 40mT range, with offset trimmed to 50% VDD ±2.5% and linearity better than ±0.5% over 360° at VDD=5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.135–3.6V or 4.5–5.5V - supports dual-rail MCU interfaces without level-shifting |
| Output Refresh Rate | 4 µs - enables 25 kRPM operation with 1.6 samples/degree resolution |
| Operating Temperature | -40°C to +150°C - qualified for under-hood and traction motor applications |
| Magnetic Axis | X/Y - optimized for end-of-shaft configurations with two-pole magnets |
| Full-Scale Range | 40 mT - matched to SmCo magnets (BAA option code), minimizing ADC headroom waste |
| Total Angular Error | ±1° with dynamic compensation - meets tight field-oriented control loop requirements |
| Package | TSSOP-16 - provides isolated die grounding and EMC-optimized pin layout for dual-channel redundancy |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 × 4.4 mm body, and exposed thermal pad (not electrically connected). Dual-die architecture requires separate power, ground, and signal routing per die to maintain fault isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Independent ground returns for Die A and Die B - mandatory separation prevents common-mode coupling |
| 5, 13 | OUT2_B / OUT2_A | Sine output channels - routed to separate ADC inputs for cross-checking |
| 8, 16 | OUT1_B / OUT1_A | Cosine output channels - phase-aligned with respective OUT2 for arctan computation |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs - must be decoupled locally; VDD3V3 pins left floating in 5V mode |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs - used only in 3.3V mode; floating in 5V operation per datasheet |
| 4, 11 | TEST_A / TEST_B | Factory test pins - tied to GND for optimal EMC; not user-accessible in normal operation |
| 2, 3, 10, 12 | NC | No-connect pins - must be grounded per EMC guidelines to suppress parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Technology | Simultaneous orthogonal field measurement eliminates mechanical alignment sensitivity in end-of-shaft setups |
| Dual-Die Redundancy | Fully independent signal chains enable lockstep comparison and fail-safe reporting per ISO 26262 ASIL-D requirements |
| Ratiometric Outputs | Output voltage scales directly with VDD - removes supply variation impact on angle calculation accuracy |
| Programmable Bandwidth | Configurable filter time constant (n=1–16) allows trade-off between noise rejection and tracking latency |
| SmCo Magnet Optimization | BAA-000 variant calibrated for SmCo's low temperature coefficient - reduces system-level thermal drift compensation burden |

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-BAA-000-RE | SOIC-8 single-die variant with identical X/Y axis, SmCo calibration, and 40mT range - lacks hardware redundancy | Suitable for non-safety-critical BLDC fans or pumps where cost and board area outweigh fault tolerance needs | Select when ASIL-B or lower is sufficient and PCB space limits TSSOP-16 placement |
| AMS AS5055A-BQFT | Single-die 12-bit SPI-output magnetic encoder with integrated angle computation - no analog COS/SIN outputs | Targets microcontroller-based systems with digital interfaces and software-based error correction capability | Choose when digital interface, smaller QFN package, or built-in arctan processing are prioritized over analog resolver compatibility |
Compared with MLX90380LGO-BAA-000-TU, the SOIC-8 MLX90380LDC-BAA-000-RE reduces cost and size but removes dual-die fault containment, while the AMS AS5055A-BQFT shifts signal processing to firmware and eliminates analog path dependencies - making MLX90380LGO-BAA-000-TU uniquely suited for legacy resolver-replacement and high-integrity analog feedback loops.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAA-000-TU?
The MLX90380LGO-BAA-000-TU is factory-programmed for X/Y magnetic axis operation, meaning OUT1 responds to the BX field component and OUT2 to the BY component. This configuration is optimized for end-of-shaft applications using two-pole magnets aligned parallel to the IC surface, as confirmed by the BAA option code in the ordering table.
Does MLX90380LGO-BAA-000-TU support both 3.3V and 5V supply rails simultaneously?
No - MLX90380LGO-BAA-000-TU operates exclusively from either 3.3V or 5V, not both. When using 5V, the VDD3V3 pins (7 and 15) must remain floating; when using 3.3V, the VDD5V pins (6 and 14) must float. This rail-select behavior is enforced by internal power-on reset thresholds and is documented in Section 13 of the datasheet.
How is redundancy implemented in MLX90380LGO-BAA-000-TU?
Redundancy in MLX90380LGO-BAA-000-TU is achieved via two physically independent die in one TSSOP-16 package, each with dedicated power supplies (VDD5V_A/VSS_A and VDD5V_B/VSS_B), analog outputs (OUT1_A/OUT2_A and OUT1_B/OUT2_B), and test pins. No shared circuitry exists between die, enabling true hardware-level fault isolation required for ASIL-D systems.
What is the full-scale magnetic range of MLX90380LGO-BAA-000-TU and which magnet type does it target?
The MLX90380LGO-BAA-000-TU has a factory-programmed full-scale magnetic range of 40 mT and is calibrated for Samarium Cobalt (SmCo) magnets, as indicated by the "BAA" option code. This pairing minimizes sensitivity temperature drift due to SmCo's low intrinsic coefficient, aligning with the device's -40°C to 150°C operating range.
Can MLX90380LGO-BAA-000-TU be used in through-shaft configurations?
No - MLX90380LGO-BAA-000-TU is configured for X/Y axis operation, which is specified for end-of-shaft and on-axis multi-pole magnet use per Table 2 of the datasheet. Through-shaft applications require Z/Y or X/Z axis variants (e.g., BAB or BAC option codes), as the X/Y geometry does not provide adequate signal amplitude in off-axis field orientations.
