Product details
Overview
MLX90380LGO-BAB-145-SP from Melexis is a monolithic Triaxis® contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs for resolver replacement in motor control systems. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4µs output refresh rate, and is factory-programmed for NdFeB magnet, Z/Y magnetic axis, 60mT full-scale range, and high-bandwidth mode.
For engineers reviewing the MLX90380LGO-BAB-145-SP datasheet, MLX90380LGO-BAB-145-SP pinout, MLX90380LGO-BAB-145-SP application in BLDC motor control, or MLX90380LGO-BAB-145-SP equivalent for automotive-grade angular sensing, this page provides verified technical context, package mapping, functional pin definitions, and real-world implementation guidance aligned with AEC-Q100-compliant design requirements.
Technical Context
The MLX90380LGO-BAB-145-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (Z) and in-plane (Y) magnetic field components, enabling absolute angular position calculation via arctangent of ratiometric OUT2/OUT1 outputs. Its dual-die TSSOP-16 architecture provides full redundancy with independent power, ground, and signal paths per die.
Factory programming configures it for Z/Y axis operation (OUT1 = COS–Z, OUT2 = SIN–Y), 60mT magnetic range, NdFeB magnet compensation (TCS ≈ 1100 ppm/°C), and high-bandwidth mode (tracking delay = 12 µs, Nyquist frequency = 125 kHz). Output offset is trimmed to 50% VDD at B = 0 mT, with linearity ≤ ±0.5% over 360° at VDD = 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angle tracking up to 25,000 RPM with <12 µs total tracking delay in high-bandwidth mode. |
| Operating Supply | 3.3V or 5V - Dual-rail support allows direct interfacing with 3.3V MCUs or legacy 5V systems without level-shifting. |
| Full-Scale Magnetic Range | 60 mT - Optimized for NdFeB magnets in end-of-shaft or through-shaft configurations with Z/Y field orientation. |
| Temperature Range | -40°C to +150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Output Linearity | ±0.5% - Validated over full 360° rotation at 5V supply, enabling high-fidelity field-oriented control without external calibration. |
| Ratiometric Outputs | OUT1 (COS–Z), OUT2 (SIN–Y) - Voltage outputs scale proportionally with VDD, rejecting supply ripple in ADC-conversion chains. |
| Total Angular Error (w/ compensation) | ±1° - Achievable using dynamic offset/gain correction in ECU firmware, meeting stringent PMSM torque control requirements. |
Pinout & Package
TSSOP-16 package with dual-die fully redundant architecture; 16-pin surface-mount outline measuring 5.0 mm × 4.4 mm × 1.2 mm (JEDEC MO-153).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Independent ground returns for Die A and Die B - must be connected to system ground for EMC compliance and noise immunity. |
| 4, 11 | TEST_A / TEST_B | Factory test pins - connect to GND for optimal EMC; not used in normal operation. |
| 5, 13 | OUT2_B / OUT2_A | Sine output (Y-axis component for Z/Y configuration) - ratiometric, 0–100% VDD swing, drives MCU ADC directly. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply input per die - leave VDD3V3 pins floating when using 5V mode per recommended application diagrams. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply input per die - leave VDD5V pins floating when using 3.3V mode; not used concurrently. |
| 8, 16 | OUT1_B / OUT1_A | Cosine output (Z-axis component for Z/Y configuration) - matched gain/offset to OUT2 for accurate arctan computation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (Z) and in-plane (Y) field measurement enables single-chip 360° absolute angle resolution without external magnets or coils. |
| Dual-Die Redundancy | Independent A/B die paths in TSSOP-16 provide fault-tolerant operation required for ASIL-B/C automotive motor control systems. |
| Programmable Bandwidth | High-bandwidth mode (125 kHz Nyquist) supports >25,000 RPM rotor speeds while maintaining <12 µs tracking delay for closed-loop FOC. |
| Z/Y Magnetic Axis | Configured for through-shaft applications where magnet flux is oriented along Z (axial) and Y (radial), matching common off-axis mechanical layouts. |
| NdFeB Magnet Optimization | Factory-set sensitivity temperature coefficient (~1100 ppm/°C) compensates for NdFeB flux decay across -40°C to 150°C, minimizing angle drift. |

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 |
|---|---|---|---|
| MLX90380LGO-BAB-143-RE | Same package and magnetic configuration, but 50mT full-scale range and medium-bandwidth mode (29.5 µs tracking delay). | Better suited for lower-RPM applications (<12,000 RPM) where reduced noise and higher SNR outweigh speed requirements. | Select when optimizing for angular accuracy over bandwidth, especially in low-vibration industrial actuators. |
| MLX90380LGO-BAB-140-RE | Identical Z/Y axis and NdFeB magnet support, but 40mT range and low-bandwidth mode (74 µs tracking delay). | Targeted at cost-sensitive applications with relaxed dynamic response, such as HVAC damper position feedback. | Choose for non-safety-critical systems where extended temperature stability and minimal calibration effort are prioritized. |
Compared with MLX90380LGO-BAB-145-SP, the -143-RE offers tighter magnetic range and lower noise at reduced speed, while the -140-RE trades bandwidth for enhanced DC stability and lower system-level filtering complexity - all three share identical pinout, redundancy architecture, and AEC-Q100 qualification.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-145-SP?
The MLX90380LGO-BAB-145-SP is factory-programmed for Z/Y magnetic axis operation, meaning OUT1 reports the cosine of the Z-axis field component and OUT2 reports the sine of the Y-axis field component. This configuration supports through-shaft mounting with axial-radial magnet orientation and is validated for use with NdFeB magnets across -40°C to 150°C.
Does MLX90380LGO-BAB-145-SP support both 3.3V and 5V supply rails simultaneously?
No - MLX90380LGO-BAB-145-SP uses either VDD3V3 or VDD5V per die, not both concurrently. When operating from 5V, the VDD3V3 pins must be left floating per Melexis' recommended application diagrams; conversely, VDD5V pins are floated in 3.3V mode. The TSSOP-16 package provides separate supply pins for each die to maintain redundancy integrity.
How is the 60mT full-scale range of MLX90380LGO-BAB-145-SP implemented?
The 60mT full-scale range is factory-programmed into the MLX90380LGO-BAB-145-SP's EEPROM during final test, setting internal gain coefficients so that ±60mT magnetic flux density produces ±40% VDD differential swing on OUT1 and OUT2 relative to their 50% VDD quiescent level. This matches NdFeB magnet strength and ensures optimal ADC utilization without external scaling.
What redundancy architecture does MLX90380LGO-BAB-145-SP employ?
MLX90380LGO-BAB-145-SP implements dual-die fully redundant architecture in a single TSSOP-16 package: Die A (pins 13–16, 1–4) and Die B (pins 5–8, 9–12) operate independently with separate VDD/VSS pairs, test pins, and analog outputs. This enables cross-checking and fail-safe operation per ISO 26262 ASIL-B/C requirements without external duplication.
Can MLX90380LGO-BAB-145-SP be reprogrammed in-system?
No - MLX90380LGO-BAB-145-SP is delivered with permanent factory programming for Z/Y axis, NdFeB magnet type, 60mT range, and high-bandwidth mode. While earlier MLX90380 variants support programming via the connector, the BAB-145 option code indicates fixed configuration; no in-field reprogramming capability exists for this specific variant.
