Product details
Overview
MLX90380LGO-BAB-000-SP from Melexis is a Triaxis® monolithic contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs with 4 µs output refresh rate, ±40%VDD swing, and ratiometric operation across -40°C to 150°C. It supports NdFeB magnets, X/Y magnetic axis configuration, and 40 mT full-scale magnetic range for end-of-shaft or through-shaft motor position sensing in automotive EPS and industrial servo drives.
For engineers reviewing the MLX90380LGO-BAB-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TSSOP-16 package details, magnetic axis selection, sensitivity programming, and real-world angular error performance under dynamic conditions up to 25,000 rpm.
Technical Context
The MLX90380LGO-BAB-000-SP implements Triaxis® Hall technology with dual-die fully redundant architecture in TSSOP-16, enabling independent X/Y field measurement per die for functional safety compliance. Its analog outputs (OUT1 = COS, OUT2 = SIN) are generated via high-speed chopping at 1 MHz and updated every 4 µs with programmable filter bandwidth (low/medium/high).
It supports 3.3 V or 5 V supply operation with ratiometric output scaling, factory-programmed NdFeB magnet compatibility (BAB), X/Y magnetic axis (BAB-00x), and 40 mT full-scale range (BAB-xx0). Output offset is stabilized at 50%VDD ±2.5% with temperature drift ≤±1.5%VDD over -40°C to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angle computation at >250 kSPS for high-speed motor control loops. |
| Full-Scale Magnetic Range | 40 mT - Matches NdFeB magnet strength in compact end-of-shaft configurations without signal saturation. |
| Operating Temperature | -40°C to 150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Supply Voltage | 3.3 V or 5 V - Dual-rail support allows direct interface with 3.3 V MCUs or legacy 5 V systems. |
| Angular Accuracy | ±1° total error with dynamic compensation - Achieved via off-chip arctan(OUT2/OUT1) with gain/offset correction. |
| Magnetic Axis | X/Y - Enables precise in-plane field detection for two-pole magnet end-of-shaft mounting. |
| Output Type | Ratiometric sine/cosine analog - Maintains proportional relationship to VDD, simplifying ADC reference design. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A (pins 1,4,13–16) and Die B (pins 5–9,11) provide independent ground, supply, test, and analog output paths for ASIL-D capable systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns per die - Prevents crosstalk and enables fault isolation in safety-critical applications. |
| 5, 13 | OUT2_B / OUT2_A | SIN outputs for Die B and Die A - Used for redundancy comparison or differential angle calculation. |
| 8, 16 | OUT1_B / OUT1_A | COS outputs for Die B and Die A - Paired with respective OUT2 pins to form independent resolver channels. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs per die - Allows independent power domain control and failure containment. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs per die - Must be left floating when using 5 V mode; enables mixed-voltage system integration. |
| 4, 11 | TEST_A / TEST_B | Factory test and programming access - Connected to GND for optimal EMC; used for EEPROM configuration during production. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Technology | Simultaneous orthogonal and in-plane field sensing eliminates need for external flux concentrators or multi-sensor assemblies. |
| Dual-Die Redundancy | Fully independent signal chains per die enable cross-checking and fail-safe reporting per ISO 26262 ASIL-D requirements. |
| Programmable Filter Bandwidth | Selectable low/medium/high bandwidth via option code - Optimizes noise rejection vs. tracking delay trade-off for specific motor speeds. |
| Ratiometric Outputs | Output voltage scales linearly with VDD - Eliminates need for precision voltage references in MCU ADC front-end design. |
| End-of-Shaft / Through-Shaft Support | X/Y magnetic axis configuration validated for both mounting styles - Reduces mechanical redesign when switching motor topologies. |

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 package, SmCo magnet optimized, same X/Y axis and 40 mT range | Lacks dual-die redundancy; suitable for non-safety-critical BLDC fans or cost-sensitive consumer motors | Select when ASIL-D compliance is not required and PCB space constraints favor SOIC-8 footprint. |
| MLX90380LGO-BAB-100-RE | Same TSSOP-16 dual-die package but programmed for 5 V supply and low bandwidth (BAB-1xx) | Better noise immunity at lower motor speeds; higher tracking delay (74 µs) reduces maximum usable RPM | Choose for slower industrial conveyors where EMI robustness outweighs update speed requirements. |
Compared with MLX90380LGO-BAB-000-SP, the SOIC-8 alternative trades redundancy for size and cost, while the BAB-100 variant sacrifices update rate for improved low-frequency noise rejection-both retain identical magnetic axis and sensitivity calibration but differ in safety architecture and dynamic response.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-000-SP?
The MLX90380LGO-BAB-000-SP is factory-programmed for X/Y magnetic axis configuration, meaning OUT1 responds to the X-component and OUT2 to the Y-component of the applied magnetic field. This configuration is optimized for two-pole magnet end-of-shaft mounting and ensures equal sensitivity between axes, as confirmed by its BAB-00x option code per Melexis datasheet Table 2.
Does MLX90380LGO-BAB-000-SP support both 3.3 V and 5 V supply operation?
Yes, MLX90380LGO-BAB-000-SP supports dual-supply operation: VDD3V3 (3.135–3.6 V) and VDD5V (4.5–5.5 V) pins are provided on each die. When using 5 V, the VDD3V3 pins must be left floating per datasheet Section 9.2 and Figure 13. The device maintains ratiometric output scaling across both rails, ensuring consistent ADC interface behavior.
How does the dual-die architecture of MLX90380LGO-BAB-000-SP improve functional safety?
The MLX90380LGO-BAB-000-SP implements physically separate Die A and Die B in TSSOP-16, each with independent ground, supply, and analog output paths. This enables cross-die comparison, fault detection, and fail-safe reporting-meeting ASIL-D requirements per ISO 26262 when integrated into a properly architected control system, unlike single-die variants such as MLX90380LDC-BAA-000-RE.
What is the maximum rotational speed supported by MLX90380LGO-BAB-000-SP?
MLX90380LGO-BAB-000-SP supports up to 25,000 rpm with high-bandwidth programming, achieving 1.6 samples per degree at that speed. Its 4 µs output update period and 125 kHz Nyquist frequency ensure minimal phase lag and accurate dynamic angle reconstruction, as specified in Table 8 of the datasheet under "Magnetic Angular Speed" and "Output Update Rate".
Can MLX90380LGO-BAB-000-SP be reprogrammed after soldering?
No, MLX90380LGO-BAB-000-SP is factory-programmed with fixed parameters including NdFeB magnet optimization (BAB), X/Y axis (00x), and 40 mT range (xx0). While the TEST pins support initial programming, Melexis does not specify post-soldering reprogramming capability; configuration is locked at production, and field adjustment requires external MCU-based signal conditioning rather than device-level reconfiguration.
