Product details
Overview
MLX90380LGO-BAB-000-RE from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs. 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 compatibility with X/Z magnetic axis and 40mT full-scale range. It enables high-accuracy rotor position feedback in brushless motor control systems.
For engineers reviewing the MLX90380LGO-BAB-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TSSOP-16 package details, magnetic axis configuration, real-time update timing, and validated alternative options for automotive and industrial motor control designs.
Technical Context
The MLX90380LGO-BAB-000-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two integrated die in a fully redundant TSSOP-16 package. Its dual-die architecture delivers independent COS and SIN outputs per die (OUT1_A/OUT2_A and OUT1_B/OUT2_B), enabling functional safety compliance via cross-checking.
It supports programmable bandwidth (high/medium/low) via external pins, with tracking delay ranging from 12 µs (high BW) to 85.5 µs (low BW), and uses internal chopping at 1 MHz to suppress offset drift. The device is preconfigured for NdFeB magnets, X/Z axis orientation, and 40mT magnetic range - all fixed at factory and non-field-programmable for this variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.135–3.6 V or 4.5–5.5 V - dual-rail support enables flexible MCU interface without level-shifting. |
| Output Refresh Rate | 4 µs - enables real-time angle computation at up to 250 kSPS for high-speed motor control loops. |
| Operating Temperature | -40°C to +150°C - qualified for under-hood automotive and industrial motor drive environments. |
| Magnetic Axis | X/Z configuration - optimized for through-shaft or off-axis magnet placement with equal sensitivity on both axes. |
| Full-Scale Range | 40 mT - matched to NdFeB magnets (BAB option code), delivering ±40% VDD output swing at 25°C. |
| Angular Accuracy | ±1° total error with dynamic compensation - enables field-oriented control (FOC) without external calibration hardware. |
| Output Type | Ratiometric sine/cosine analog - maintains proportionality to supply voltage, simplifying ADC reference design. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: two independent sensor dies (Die A and Die B), each with dedicated power, ground, test, and analog output pins. Pin 1 is VSS_A (ground for Die A); Pin 9 is VSS_B (ground for Die B); Pins 5/8 and 13/16 carry complementary SIN/COS outputs for redundancy verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns per die - prevents crosstalk and supports fault-isolation diagnostics. |
| 5, 13 | OUT2_B / OUT2_A | SIN outputs for Die B and Die A - used for real-time comparison to detect single-point failures. |
| 8, 16 | OUT1_B / OUT1_A | COS outputs for Die B and Die A - paired with respective SIN outputs to reconstruct angle per die. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs per die - allows independent power domain control for safety monitoring. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs per die - must be floated when using 5V mode per datasheet Section 9.2. |
| 2, 3, 10, 12 | NC | No-connect pins - require grounding per EMC guidelines to minimize radiated emissions. |
| 4, 11 | TEST_A / TEST_B | Factory test access points - grounded in production for optimal noise immunity and ESD robustness. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Independent X/Z sensing paths per die enable ASIL-B/C diagnostic coverage per ISO 26262. |
| Programmable bandwidth | Three selectable filter settings (high/medium/low) allow trade-off between latency (12 µs) and noise rejection. |
| Ratiometric analog outputs | Outputs scale linearly with VDD - eliminates need for precision voltage references in MCU ADC subsystems. |
| Chopped Hall front-end | 1 MHz chopping frequency suppresses 1/f noise and thermal drift, ensuring stable offset over temperature. |
| NdFeB-optimized sensitivity | Factory-set 40 mT full-scale range matches common NdFeB magnet strengths, maximizing signal-to-noise ratio. |
Applications
| Brushless Motor Rotor Position | Electric Power Steering (EPS) |

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-BAA-000-RE | SmCo magnet optimization (vs. NdFeB), same X/Z axis and 40mT range; higher TCS (350 ppm/°C vs. 1100 ppm/°C). | Better suited for high-temperature stability with SmCo magnets; less sensitive to NdFeB flux decay over temperature. | Select when using SmCo magnets or requiring lower sensitivity temperature drift in >125°C ambient. |
| MLX90380LGO-BAC-000-RE | Ferrite magnet optimization; same X/Z axis and 40mT range; highest TCS (2000 ppm/°C) for aggressive flux compensation. | Designed for cost-sensitive applications using ferrite magnets; requires tighter mechanical tolerances due to lower field strength. | Choose for ferrite-based systems where magnet cost dominates and thermal compensation is managed externally. |
Compared with MLX90380LGO-BAB-000-RE, the BAA variant offers superior thermal stability with SmCo magnets but higher cost, while the BAC variant enables lowest-cost magnet solutions at the expense of increased sensitivity drift - both retain identical TSSOP-16 packaging and dual-die redundancy.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-000-RE?
The MLX90380LGO-BAB-000-RE is factory-programmed for X/Z magnetic axis configuration with equal sensitivity on both axes, enabling accurate sensing in through-shaft or off-axis magnet arrangements. This setting is fixed and cannot be reprogrammed in the field, as confirmed by the BAB option code in Table 2 of the datasheet.
Does MLX90380LGO-BAB-000-RE support both 3.3V and 5V supply rails simultaneously?
No - MLX90380LGO-BAB-000-RE supports either 3.3V or 5V operation, but not both simultaneously. When using 5V, the VDD3V3 pins (7 and 15) must be left floating per Section 9.2 of the datasheet; conversely, VDD5V pins (6 and 14) must float during 3.3V operation to prevent damage or incorrect biasing.
What is the purpose of the dual-die architecture in MLX90380LGO-BAB-000-RE?
The dual-die TSSOP-16 implementation in MLX90380LGO-BAB-000-RE provides hardware-level redundancy: Die A and Die B independently generate COS/SIN outputs, allowing cross-checking for fault detection. This architecture supports ASIL-B/C compliance per ISO 26262 in automotive safety applications such as EPS and traction inverters.
Can the sensitivity range of MLX90380LGO-BAB-000-RE be changed after manufacturing?
No - the 40mT full-scale magnetic range of MLX90380LGO-BAB-000-RE is factory-programmed and permanently fixed. Option code BAB-000 specifies NdFeB magnet compatibility and 40mT range (per Table 2); no field programming capability exists for sensitivity or magnetic axis configuration on this variant.
How does the ratiometric output behavior of MLX90380LGO-BAB-000-RE benefit system design?
The ratiometric outputs of MLX90380LGO-BAB-000-RE scale linearly with VDD, meaning output voltage = 50% VDD at zero field and ±40% VDD at full scale. This eliminates dependency on a separate precision voltage reference for the MCU's ADC, reducing BOM cost and improving system-level accuracy against supply rail variations.
