Product details
Overview
MLX90380LGO-BAB-005-RE from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, 5V supply operation, and -40°C to 150°C operating range-used in high-reliability brushless motor control and field-oriented control systems.
For engineers reviewing the MLX90380LGO-BAB-005-RE datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die redundant resolver supports NdFeB magnets, X/Z magnetic axis configuration, 60 mT full-scale range, and high-bandwidth programming for dynamic motor shaft angle tracking.
Technical Context
The MLX90380LGO-BAB-005-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two independent die in a single TSSOP-16 package, enabling fully redundant sine/cosine signal generation. Its dual-die architecture provides fault-tolerant operation critical for automotive and industrial safety-critical motion control.
It delivers ratiometric analog outputs referenced to VDD5V, with programmable sensitivity (60 mT full-scale), selectable bandwidth (high BW mode), and on-chip signal conditioning including chopping at 1 MHz and sample-and-hold filtering. Angular accuracy is maintained across temperature via factory-programmed sensitivity temperature coefficient for NdFeB magnets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angular tracking up to 25,000 rpm with ≤74 µs total tracking delay in high-bandwidth mode. |
| Supply Voltage | 4.5–5.5 V - Operates exclusively from 5V rail; VDD3V3 pin must be left floating in this configuration. |
| Full-Scale Magnetic Range | 60 mT - Factory-programmed for NdFeB magnets, supporting robust sensing under mechanical misalignment or thermal drift. |
| Magnetic Axis | X/Z - Outputs OUT1 = COS(X), OUT2 = SIN(Z); enables through-shaft or off-axis magnet placement per Figure 7. |
| Operating Temperature | -40°C to 150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Angular Accuracy | ±1° total error with dynamic compensation - Achieved via external ECU offset/gain correction applied before arctan(OUT2/OUT1). |
| Package | TSSOP-16 - Dual-die fully redundant layout with separate ground, supply, and output pins for each die (A/B). |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A (pins 1, 4, 13–16) and Die B (pins 5–9, 11) operate independently, sharing no internal connections-enabling functional safety monitoring via cross-checking of outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Independent ground returns for each die-must be connected to system ground separately for EMC and fault isolation. |
| 5, 13 | OUT2_B / OUT2_A | SIN outputs for Die B and Die A-provide redundant sine signals for comparison or voting logic in ASIL-B/C systems. |
| 8, 16 | OUT1_B / OUT1_A | COS outputs for Die B and Die A-paired with respective OUT2 pins to form independent sine/cosine channels. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs per die-allow independent power domain monitoring and fault detection. |
| 4, 11 | TEST_A / TEST_B | Test pins for factory calibration and diagnostics-must be tied to ground for optimal EMC performance. |
| 2, 3, 10, 12 | NC | No-connect pins-require grounding per datasheet to minimize radiated emissions and crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Independent A/B signal chains in one TSSOP-16 package enable hardware-level fault detection without external circuitry. |
| X/Z magnetic axis | Supports through-shaft magnet configurations with Z-axis sensitivity matched to X-axis-ideal for compact BLDC rotor position sensing. |
| NdFeB magnet optimization | BAB-005 option code configures sensitivity temperature coefficient (1100 ppm/°C) to compensate NdFeB flux loss over temperature. |
| Ratiometric analog outputs | Outputs scale linearly with VDD, eliminating need for precision voltage references and simplifying ADC interface design. |
| High-bandwidth programming | Enables 4 µs update period and ≤74 µs tracking delay-critical for fast-response FOC algorithms in PMSM drives. |
Applications
| Brushless Motor Control | Field-Oriented Control (FOC) |

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-003-RE | Same TSSOP-16 dual-die package and X/Z axis, but 30 mT full-scale range and medium-bandwidth programming. | Lower magnetic range suits smaller NdFeB magnets or tighter air gaps; 29.5 µs tracking delay vs. 74 µs limits max speed to ~10,000 rpm. | Select when mechanical constraints reduce available flux density or when lower bandwidth suffices for cost-sensitive designs. |
| MLX90380LDC-BAB-005-RE | SOIC-8 single-die variant with identical BAB-005 programming (NdFeB, 60 mT, X/Z, 5V, high BW), same electrical specs. | Lacks redundancy-suitable for non-safety-critical applications; smaller footprint but no fault-tolerant capability. | Choose for space-constrained PCBs where functional safety is not required, reducing BOM count and layout complexity. |
Compared with MLX90380LGO-BAB-005-RE, the BAB-003-RE offers faster response at reduced magnetic range, while the LDC-BAB-005-RE provides identical sensing performance in a smaller, non-redundant package-enabling tiered design reuse across safety and cost segments.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-005-RE?
The MLX90380LGO-BAB-005-RE is factory-programmed for X/Z magnetic axis operation, meaning OUT1 carries the cosine of the X-axis field component and OUT2 carries the sine of the Z-axis field component. This configuration supports through-shaft magnet arrangements and is confirmed by the 'BAB' option code per Table 2 in the datasheet.
Does MLX90380LGO-BAB-005-RE support both 3.3V and 5V supply operation?
No-MLX90380LGO-BAB-005-RE is configured for 5V-only operation. The '005' suffix indicates high-bandwidth programming with 5V supply; VDD3V3 pins must remain floating. Datasheet Section 13.2.2 confirms dedicated 5V application diagrams for TSSOP-16 devices with this option code.
How does the dual-die redundancy in MLX90380LGO-BAB-005-RE improve system reliability?
The MLX90380LGO-BAB-005-RE integrates two independent sensing die (A and B) in one TSSOP-16 package, each with separate grounds, supplies, and analog outputs. This allows real-time cross-comparison of sine/cosine pairs to detect faults-meeting requirements for ASIL-B/C functional safety without external redundancy circuitry.
What is the full-scale magnetic range and magnet type supported by MLX90380LGO-BAB-005-RE?
The MLX90380LGO-BAB-005-RE has a factory-programmed full-scale magnetic range of 60 mT and is optimized for NdFeB magnets, as indicated by the 'BAB' prefix in its option code. This setting configures the sensitivity temperature coefficient to 1100 ppm/°C to compensate for NdFeB flux degradation over temperature.
Can MLX90380LGO-BAB-005-RE be used in automotive under-hood applications?
Yes-MLX90380LGO-BAB-005-RE is qualified for -40°C to 150°C operation and packaged in RoHS-compliant TSSOP-16. Its dual-die redundancy, AEC-Q100 stress testing, and 150°C junction rating make it suitable for engine bay and transmission-mounted motor control units.
