Product details
Overview
MLX90380LGO-BAB-043-RE from Melexis is a Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, 3.3 V/5 V dual-supply support, and operation from −40 °C to +150 °C. It uses NdFeB magnet compatibility (BAB), X/Z magnetic axis configuration, and 30 mT full-scale magnetic range for end-of-shaft or through-shaft motor rotor position feedback in high-reliability automotive and industrial BLDC/PMSM systems.
For engineers reviewing the MLX90380LGO-BAB-043-RE datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die fully redundant resolver sensor supports field-oriented control loop timing, high-bandwidth position acquisition, and programmable sensitivity/filter bandwidth via application pins - critical for ECU-level arctan(OUT2/OUT1) computation and dynamic error compensation.
Technical Context
The MLX90380LGO-BAB-043-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two independent monolithic dies in a single TSSOP-16 package. Its dual-die architecture provides hardware redundancy for ASIL-B/C functional safety compliance in motor control applications.
It delivers synchronized sine/cosine outputs with ≤12 µs tracking delay (high-bandwidth mode), ±0.5% linearity over 360°, and total angular error reduced to ±1° with dynamic offset/gain compensation. Sensitivity is factory-programmed to 1.33 %VDD/mT (30 mT range) for NdFeB magnets, with X/Z axis configuration enabling off-axis through-shaft mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - enables real-time position sampling at up to 250 kSPS for high-speed motor control loops. |
| Operating Supply | 3.3 V or 5 V - selectable via dedicated VDD3V3/VDD5V pins; supports mixed-voltage system integration. |
| Full-Scale Magnetic Range | 30 mT - optimized for NdFeB magnets in compact end-of-shaft configurations with minimal air gap. |
| Angular Accuracy | ±1° with dynamic compensation - achieved via external ECU correction of offset, gain, and phase prior to arctan calculation. |
| Temperature Range | −40 °C to +150 °C - qualified for under-hood automotive and industrial motor drive environments. |
| Magnetic Axis | X/Z - supports through-shaft mounting where magnet flux is applied along Z (axial) and X (radial) directions. |
| Package | TSSOP-16 - dual-die fully redundant layout with separate ground, supply, and output pins per die for fault isolation. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A and Die B each provide independent COS/SIN outputs, dedicated supplies (VDD3V3_A/VDD5V_A and VDD3V3_B/VDD5V_B), grounds (VSS_A/VSS_B), and test pins (TEST_A/TEST_B). Unused pins (NC) must be grounded for EMC compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns per die - enable galvanic isolation between redundant signal paths. |
| 5, 13 | OUT2_B / OUT2_A | Sine analog outputs - ratiometric to respective VDD, require external ADC with ≥12-bit resolution. |
| 8, 16 | OUT1_B / OUT1_A | Cosine analog outputs - paired with OUT2 for arctan-based angle computation in host MCU. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs - used when operating at 5 V; VDD3V3 pins must float in this mode. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs - used when operating at 3.3 V; VDD5V pins must float in this mode. |
| 4, 11 | TEST_A / TEST_B | Factory test access - grounded during normal operation to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies. |
| Dual-Die Redundancy | Independent A/B die outputs allow cross-checking and fail-safe reporting in ISO 26262-compliant motor control ECUs. |
| Programmable Bandwidth | High-bandwidth mode (≤12 µs tracking delay) supports >25,000 rpm rotor speeds without phase lag in FOC loops. |
| Ratiometric Outputs | Output voltage scales linearly with VDD - eliminates supply ripple impact on angle accuracy in noisy power domains. |
| Factory-Programmed Axis & Range | X/Z axis + 30 mT range (BAB-043) ensures optimal SNR and linearity for NdFeB-based through-shaft designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resolver sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LGO-BAB-023-RE | Same TSSOP-16 package and X/Z axis, but 20 mT full-scale range (1.33 %VDD/mT → 0.66 %VDD/mT sensitivity). | Better suited for low-field NdFeB magnets or larger air gaps; lower output swing reduces ADC utilization efficiency. | Select when magnet strength or mechanical clearance requires reduced magnetic range without changing PCB layout. |
| MLX90380LGO-BAB-053-RE | Same TSSOP-16 package and X/Z axis, but 50 mT full-scale range (1.33 %VDD/mT → 2.66 %VDD/mT sensitivity). | Higher sensitivity improves SNR in low-noise systems but increases susceptibility to stray fields and temperature drift. | Select for high-precision applications with stable magnetic environments and tight thermal management. |
Compared with MLX90380LGO-BAB-023-RE and MLX90380LGO-BAB-053-RE, the MLX90380LGO-BAB-043-RE offers balanced sensitivity and noise immunity for standard NdFeB-based through-shaft deployments, requiring no layout change but delivering optimal dynamic range utilization across −40 °C to +150 °C.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-043-RE?
The MLX90380LGO-BAB-043-RE is configured for X/Z magnetic axis operation, meaning OUT1 measures the X-component (radial) and OUT2 measures the Z-component (axial) of the applied magnetic field. This configuration supports through-shaft mounting with off-axis magnet placement and is factory-programmed - no external programming is required to activate this axis selection.
Does MLX90380LGO-BAB-043-RE support both 3.3 V and 5 V supply voltages simultaneously?
No - MLX90380LGO-BAB-043-RE supports either 3.3 V or 5 V operation, not both simultaneously. When using 3.3 V, connect VDD3V3_A/B and leave VDD5V_A/B floating; when using 5 V, connect VDD5V_A/B and leave VDD3V3_A/B floating. Mixing supplies risks undefined behavior and violates absolute maximum ratings.
What is the full-scale magnetic range and sensitivity of MLX90380LGO-BAB-043-RE?
The MLX90380LGO-BAB-043-RE has a factory-programmed full-scale magnetic range of 30 mT and nominal sensitivity of 1.33 %VDD/mT. At 5 V supply, this yields ±2 V output swing (40% of 5 V) per axis at full scale; at 3.3 V, it yields ±1.32 V. Sensitivity is fixed per option code and cannot be reprogrammed in the field.
How does the dual-die redundancy in MLX90380LGO-BAB-043-RE improve functional safety?
The dual-die architecture in MLX90380LGO-BAB-043-RE provides physically independent signal chains (Die A and Die B), each with dedicated supplies, grounds, and outputs. This enables cross-die comparison in the host ECU to detect faults such as open-circuit, short-to-rail, or parametric drift - satisfying diagnostic coverage requirements for ASIL-B/C motor control systems per ISO 26262.
Can MLX90380LGO-BAB-043-RE be used with ferrite or SmCo magnets?
No - the "BAB" option code explicitly designates NdFeB magnet compatibility. Using ferrite or SmCo magnets with MLX90380LGO-BAB-043-RE will result in suboptimal output amplitude and increased angular error due to mismatched sensitivity temperature coefficient (TCS) and magnetic range calibration. For SmCo, use BAA-coded variants; for ferrite, use BAC-coded variants.
