Product details
Overview
MLX90380LGO-BAB-025-RE from Melexis is a dual-die, fully redundant Triaxis® resolver IC delivering true 360° sine/cosine analog outputs for absolute rotary position sensing. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4 µs output refresh rate, and is factory-programmed for NdFeB magnet compatibility, X/Z magnetic axis configuration, and 60 mT full-scale magnetic range.
For engineers reviewing the MLX90380LGO-BAB-025-RE datasheet, pinout, applications, or equivalent options, this device serves as a high-reliability angular position sensor in safety-critical motor control systems where redundancy, wide temperature operation, and ratiometric analog outputs are required.
Technical Context
The MLX90380LGO-BAB-025-RE implements dual independent Hall-based die in TSSOP-16 packaging, each with dedicated VDD/VSS/OUT/TEST pins, enabling fault-tolerant operation. Its Triaxis® architecture measures orthogonal (X/Z) magnetic field components simultaneously using integrated planar and vertical Hall elements.
Programmable bandwidth (high BW mode), selectable sensitivity (60 mT range), and X/Z axis assignment are fixed at factory via option code BAB-025 - confirming 5V supply support, medium bandwidth, and X/Z magnetic axis with equal sensitivity per datasheet Table 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Dual ratiometric analog: OUT1 = COS, OUT2 = SIN, proportional to BX and BZ |
| Output Refresh Rate | 4 µs - enables real-time angle computation up to 25,000 rpm without interpolation delay |
| Supply Voltage | 3.3V or 5V - dual supply pins (VDD3V3_A/B, VDD5V_A/B) allow flexible system-level rail selection |
| Operating Temperature | -40°C to +150°C - qualified for under-hood automotive and industrial motor drive environments |
| Magnetic Range | 60 mT full-scale - optimized for NdFeB magnets in end-of-shaft or through-shaft configurations |
| Magnetic Axis | X/Z - OUT1 responds to BX, OUT2 to BZ; equal sensitivity ensures balanced signal amplitude |
| Redundancy Architecture | Dual-die TSSOP-16 - independent power, ground, and signal paths per die for ASIL-D capable systems |
Pinout & Package
TSSOP-16 package with exposed thermal pad; RoHS-compliant, automotive-grade molding compound; 5.0 mm × 4.4 mm × 1.2 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns for Die A and Die B - mandatory for EMC integrity and fault isolation |
| 5, 13 | OUT2_B / OUT2_A | SIN output channels - each tied to respective die's vertical Hall element measuring BZ |
| 8, 16 | OUT1_B / OUT1_A | COS output channels - each tied to respective die's planar Hall element measuring BX |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs - used when operating in 5V mode; VDD3V3 pins must be left floating |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs - used when operating in 3.3V mode; VDD5V pins must be left floating |
| 2, 3, 10, 12 | NC | No-connect pins - must be connected to ground per datasheet for optimal EMC performance |
| 4, 11 | TEST_A / TEST_B | Factory test access - grounded during normal operation to suppress noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Technology | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies |
| Programmable Bandwidth | High-bandwidth mode (BAB-025) achieves 125 kHz Nyquist frequency and 12 µs tracking delay for fast dynamic response |
| Ratiometric Outputs | Output voltage scales directly with VDD - removes dependency on stable reference voltage in MCU ADC front-end |
| End-of-Shaft / Through-Shaft Support | X/Z axis configuration matches mechanical layouts requiring off-axis magnet placement or axial field detection |
| Factory Calibration | Pre-programmed for NdFeB magnet, 60 mT range, and X/Z axis - eliminates field calibration during production |
Applications

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-023-RE | Same dual-die TSSOP-16 package and X/Z axis, but 30 mT full-scale range and 3.3V-only supply support | Optimized for lower-field NdFeB magnets and systems constrained to 3.3V rails | Select when magnetic air gap is larger or magnet strength is reduced; requires redesign of ADC input scaling. |
| MLX90380LDC-BAB-025-RE | Single-die SOIC-8 variant with identical BAB-025 programming (NdFeB, X/Z, 60 mT, 5V) | Lacks hardware redundancy; suitable for non-safety-critical or cost-sensitive applications | Choose for space-constrained PCBs where ASIL-D is not mandated and footprint reduction outweighs fault tolerance. |
Compared with MLX90380LGO-BAB-025-RE, the -023-RE variant trades magnetic range and supply flexibility for lower field sensitivity, while the -BAA-025-RE offers identical functionality in a smaller, non-redundant package - making the GO variant uniquely suited for high-integrity motor control where dual-die diagnostics are mandatory.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-025-RE?
The MLX90380LGO-BAB-025-RE is factory-programmed for X/Z magnetic axis configuration, meaning OUT1 reports the X-axis magnetic field component (BX) and OUT2 reports the Z-axis component (BZ). This configuration supports both end-of-shaft and through-shaft magnet placements, and the BAB option code confirms equal sensitivity between axes per Melexis datasheet Table 2.
Does MLX90380LGO-BAB-025-RE support both 3.3V and 5V supply operation?
Yes, MLX90380LGO-BAB-025-RE supports both 3.3V and 5V supply voltages, but not simultaneously. The BAB-025 option code specifies high-bandwidth mode with 5V operation - therefore VDD5V_A/B pins must be powered at 4.5–5.5V, and VDD3V3_A/B pins must remain floating. Using 3.3V would require a different option code (e.g., BAB-024).
How does the dual-die architecture of MLX90380LGO-BAB-025-RE improve system reliability?
The dual-die TSSOP-16 implementation in MLX90380LGO-BAB-025-RE provides physically independent signal chains - separate VDD/VSS/OUT/TEST pins per die - enabling cross-die comparison for fault detection. This architecture supports diagnostic coverage required for ASIL-D systems, unlike single-die variants such as MLX90380LDC-BAB-025-RE.
What is the full-scale magnetic range programmed in MLX90380LGO-BAB-025-RE?
The MLX90380LGO-BAB-025-RE is programmed for a 60 mT full-scale magnetic range, corresponding to the "xx5" suffix in the option code per datasheet Table 2. This range is optimized for NdFeB magnets and delivers ±40% VDD output swing at TA = 25°C with VOQ = 50% VDD, ensuring maximum ADC utilization in 12-bit or higher resolution controllers.
Can MLX90380LGO-BAB-025-RE be used in through-shaft motor configurations?
Yes, MLX90380LGO-BAB-025-RE supports through-shaft operation via its X/Z magnetic axis configuration. In this layout, the magnet rotates perpendicular to the IC surface, generating orthogonal BX and BZ fields detectable by the Triaxis® architecture - confirmed in datasheet Section 2 (Application Examples) and Figure 2 (Through Shaft).
