Product details
Overview
MLX90380LGO-BAB-045-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, -40°C to 150°C operating range, and factory-programmed NdFeB magnet sensitivity for 60 mT full-scale magnetic range in TSSOP-16 dual-die redundant configuration-used in high-reliability motor control systems.
For engineers reviewing the MLX90380LGO-BAB-045-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-specific pin definitions, magnetic axis configuration (X/Z), bandwidth setting (high BW), and real-world selection guidance against comparable resolver alternatives.
Technical Context
The MLX90380LGO-BAB-045-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two independent die in TSSOP-16, enabling robust angle computation via arctan(OUT2/OUT1). Its dual-die architecture supports functional safety requirements through redundancy.
Factory-programmed for NdFeB magnets (BAB), 60 mT full-scale range (xx5), X/Z magnetic axis (x1x), and high-bandwidth operation (x5x), it delivers 1.6 samples/degree at 25,000 rpm with ≤1° total angular error after dynamic compensation and operates from either 3.3 V or 5 V supply rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Dual ratiometric analog: OUT1 = COS, OUT2 = SIN, both referenced to VDD |
| Refresh Rate | 4 µs per field component (8 µs full sine/cosine pair); enables real-time FOC at >25 kRPM |
| Magnetic Range | 60 mT full-scale (BAB-xx5), optimized for NdFeB magnets with ±5% sensitivity accuracy |
| Operating Temp | -40°C to +150°C junction temperature; qualified per AEC-Q100 Grade 0 for automotive powertrain |
| Supply Voltage | Supports dual-rail operation: 3.135–3.6 V or 4.5–5.5 V; VDD3V3 and VDD5V pins are separate |
| Angular Accuracy | ≤ ±1° total error with dynamic compensation; ≤ ±10° uncorrected at 25°C |
| Bandwidth Mode | High bandwidth (BAB-045 → x5x): Nyquist frequency = 125 kHz, tracking delay = 12 µs |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A (pins 13–16, 14–15) and Die B (pins 5–8, 6–7) provide fully independent ground, supply, test, and analog output paths for fault-tolerant operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns for each die; mandatory independent grounding for EMC and redundancy integrity |
| 5, 13 | OUT2_B / OUT2_A | SIN outputs for Die B and Die A; require matched trace routing to preserve phase alignment |
| 8, 16 | OUT1_B / OUT1_A | COS outputs for Die B and Die A; used jointly with corresponding OUT2 for arctan-based angle calculation |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs per die; must be decoupled locally with ≥100 nF ceramic capacitor |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs per die; left floating when using 5 V mode per datasheet requirement |
| 4, 11 | TEST_A / TEST_B | Factory test pins; recommended tied to GND for optimal EMC in final design |
| 2, 3, 10, 12 | NC | No-connect pins; must be grounded per datasheet for EMC compliance and noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies |
| Programmable Magnetic Axis | X/Z configuration (BAB-045 → x1x) enables compatibility with off-axis through-shaft magnet arrangements |
| Ratiometric Outputs | Output voltage scales directly with VDD, removing dependency on stable reference voltage in MCU ADC path |
| Dual-Die Redundancy | Independent signal chains (Die A + Die B) support ASIL-D decomposition for ISO 26262-compliant motor control |
| High-Speed Update | 4 µs per channel enables closed-loop FOC at >25,000 rpm without interpolation latency |
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-043-RE | Same package and magnetic axis, but 30 mT full-scale range (BAB-xx3) and medium bandwidth (x3x) | Better suited for lower-speed BLDC fans or pumps where SNR > bandwidth priority | Select when system uses smaller NdFeB magnets or requires reduced EMI via lower chopping frequency |
| MLX90380LGO-BAB-145-RE | Identical specs except extended temperature screening (165°C max junction) and enhanced ESD (2 kV HBM) | Required for engine bay applications exceeding 150°C ambient or high-EMI combustion environments | Choose for under-hood ICE hybrid systems or dual-fuel powertrain control where extended thermal margin is mandated |
Compared with MLX90380LGO-BAB-045-RE, the -043-RE trades update speed for higher SNR at low fields, while the -145-RE adds thermal and ESD headroom without altering core functionality-making all three suitable for PMSM but differentiated by speed, magnet size, and environmental severity.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-045-RE?
The MLX90380LGO-BAB-045-RE is factory-programmed for X/Z magnetic axis (option code BAB-045 → x1x), meaning OUT1 reports the Z-axis field component and OUT2 reports the X-axis field component. This configuration supports off-axis through-shaft magnet mounting and is validated for two-pole magnet use cases per datasheet Figure 7.
Does MLX90380LGO-BAB-045-RE support both 3.3 V and 5 V supply rails simultaneously?
No-MLX90380LGO-BAB-045-RE supports either 3.3 V or 5 V operation, not both concurrently. When using 5 V, the VDD3V3 pins (7 and 15) must be left floating per datasheet Section 9.2 and Figure 13; when using 3.3 V, VDD5V pins (6 and 14) are floated. Supply selection is determined by external circuitry, not internal switching.
How is redundancy implemented in MLX90380LGO-BAB-045-RE?
MLX90380LGO-BAB-045-RE uses physically separate Die A and Die B in the TSSOP-16 package, each with independent VSS, VDD, TEST, OUT1, and OUT2 terminals. This enables true hardware redundancy: failure in one die does not affect the other, supporting ASIL-D decomposition when paired with dual-lockstep MCUs and independent signal conditioning.
What is the factory-programmed sensitivity range for MLX90380LGO-BAB-045-RE?
The MLX90380LGO-BAB-045-RE is programmed for a 60 mT full-scale magnetic range (option code xx5), optimized for NdFeB magnets (BAB prefix). At 5 V supply, this yields ~300 mV/mT sensitivity (60 mT × 5 V × 1%VDD/mT), delivering ±3 V output swing centered at 2.5 V for maximum ADC utilization.
Can MLX90380LGO-BAB-045-RE be reprogrammed in-system?
No-MLX90380LGO-BAB-045-RE is factory-programmed during final test and does not support in-system reprogramming. Configuration parameters (magnetic axis, sensitivity, bandwidth) are permanently stored in EEPROM and locked. Field updates require replacement with a differently coded variant such as MLX90380LGO-BAB-043-RE.
