Product details
Overview
MLX90380LGO-BAB-103-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, 3.3 V/5 V dual-supply support, and operation from −40 °C to 150 °C. It interfaces directly with rotating permanent magnets in end-of-shaft or through-shaft configurations for high-accuracy motor commutation.
For engineers reviewing the MLX90380LGO-BAB-103-SP datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die redundant resolver provides factory-programmed NdFeB magnet sensitivity (30 mT full-scale range), X/Z magnetic axis configuration, and high-bandwidth operation optimized for BLDC and PMSM field-oriented control loops.
Technical Context
The MLX90380LGO-BAB-103-SP implements Triaxis® Hall technology to simultaneously sense orthogonal and parallel magnetic flux components (BX, BZ) on a single die, enabling precise angle computation without external magnets or gears. Its dual-die TSSOP-16 architecture delivers functional redundancy for ASIL-B/C automotive safety compliance.
Programmable filter bandwidth (high BW mode), selectable magnetic axis (X/Z), and ratiometric analog outputs (OUT1 = COS, OUT2 = SIN) allow direct interfacing with MCU ADCs while maintaining linearity better than ±0.5% over temperature. Sensitivity is factory-set to 30 mT full-scale range using NdFeB magnets, with 1%VDD/mT nominal gain and ±5% sensitivity mismatch between axes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angle tracking up to 25,000 rpm with <74 µs total tracking delay in high-bandwidth mode. |
| Operating Supply | 3.3 V or 5 V - Dual-rail support allows flexible integration with 3.3 V microcontrollers or 5 V analog signal chains. |
| Full-Scale Magnetic Range | 30 mT - Factory-programmed for NdFeB magnets; matches common off-axis magnet geometries in through-shaft applications. |
| Magnetic Axis | X/Z - Output OUT1 corresponds to BX, OUT2 to BZ; supports two-pole magnet off-axis mounting per datasheet Figure 7. |
| Angular Accuracy | ±1° total error with dynamic compensation - Achieved via external ECU offset/gain correction applied before arctan(OUT2/OUT1). |
| Temperature Range | −40 °C to +150 °C - Qualified for under-hood automotive and industrial motor drive environments. |
| Package | TSSOP-16 - Dual-die fully redundant layout meets functional safety requirements for critical motion control systems. |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad. Dual-die architecture provides independent power, ground, and output paths for Die A and Die B to enable redundancy.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns for each die-mandatory for noise isolation and fault containment in redundant systems. |
| 4, 11 | TEST_A / TEST_B | Factory test pins; must be tied to GND for optimal EMC per datasheet Section 9.2. |
| 5, 13 | OUT2_B / OUT2_A | Sine outputs for Die B and Die A-ratiometric, 0–100% VDD swing, ±0.5% linearity at VDD=5 V. |
| 8, 16 | OUT1_B / OUT1_A | Cosine outputs for Die B and Die A-phase-aligned with respective OUT2 pins for coherent angle reconstruction. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs-used when operating in 5 V mode; VDD3V3 pins must remain floating. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs-used when operating in 3.3 V mode; VDD5V pins must remain floating. |
Key Features
| Feature | Design Value |
|---|---|

| Ratiometric Sine/Cosine Outputs | Outputs scale linearly with supply voltage (VDD), eliminating need for precision voltage references in MCU ADC signal chains. |
| Programmable Bandwidth | High-bandwidth mode achieves 1.6 samples/degree at 25,000 rpm-critical for fast-response servo and traction motor control. |
| Factory-Configured Option Code | BAB-103 specifies NdFeB magnet compatibility, 30 mT full-scale range, X/Z axis, and high-bandwidth operation-no field programming required. |

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-100-RE | Same TSSOP-16 dual-die package and X/Z axis, but 40 mT full-scale range and low-bandwidth mode. | Lower sensitivity suits stronger NdFeB magnets; slower 12 µs tracking delay limits max speed to ~10,000 rpm. | Select for cost-sensitive, lower-speed BLDC applications where bandwidth headroom is not required. |
| MLX90380LDC-BAB-103-RE | SOIC-8 single-die variant with identical BAB-103 option code (30 mT, X/Z, high BW), same electrical specs. | Lacks dual-die redundancy; unsuitable for ASIL-B/C systems requiring fault containment. | Choose for space-constrained non-safety-critical applications where TSSOP-16 footprint and redundancy are unnecessary. |
Compared with MLX90380LGO-BAB-103-SP, the -100-RE offers higher magnetic range but reduced speed capability, while the -103-RE SOIC-8 version sacrifices redundancy for smaller size-making the TSSOP-16 dual-die variant uniquely suited for safety-critical high-speed motor control.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-103-SP?
The MLX90380LGO-BAB-103-SP is factory-programmed with X/Z magnetic axis configuration, meaning OUT1 reports the BX (in-plane) component and OUT2 reports the BZ (axial) component. This matches two-pole magnet off-axis mounting per datasheet Figure 7 and supports through-shaft applications where flux is oriented perpendicular to the IC surface.
Does MLX90380LGO-BAB-103-SP require external programming for operation?
No, MLX90380LGO-BAB-103-SP ships pre-programmed with option code BAB-103: NdFeB magnet compatibility, 30 mT full-scale range, X/Z axis, and high-bandwidth mode. No external programming is needed-only correct supply voltage (3.3 V or 5 V) and proper grounding of TEST/NC pins per datasheet Section 9.2.
How does the dual-die architecture of MLX90380LGO-BAB-103-SP improve system reliability?
The TSSOP-16 dual-die layout provides physically independent signal paths for Die A and Die B-including separate VDD, VSS, OUT1, and OUT2 terminals. This enables hardware-level redundancy, allowing cross-checking of angle outputs and fault isolation in ASIL-B/C systems without software intervention.
What is the maximum rotational speed supported by MLX90380LGO-BAB-103-SP?
MLX90380LGO-BAB-103-SP supports up to 25,000 rpm with high-bandwidth programming, achieving 1.6 samples per degree and <74 µs total tracking delay. At this speed, angular resolution remains within ±1° when combined with dynamic ECU compensation algorithms per datasheet Table 8.
Can MLX90380LGO-BAB-103-SP operate from both 3.3 V and 5 V supplies?
Yes, MLX90380LGO-BAB-103-SP supports dual-supply operation: use either VDD3V3_A/B pins (3.135–3.6 V) or VDD5V_A/B pins (4.5–5.5 V), but never both simultaneously. The unused supply rail must be left floating, and corresponding ground pins (VSS_A/B) must be connected per datasheet Section 9.2.
