Product details
Overview
MLX90380LDC-BAB-506-SP from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via ratiometric sine/cosine analog outputs, with 70 mT full-scale magnetic range (NdFeB magnet), 4 µs output refresh rate, and operation from -40°C to 150°C across 3.3 V or 5 V supply. It serves as the core magnetic angle transducer in high-reliability motor control systems.
For engineers reviewing the MLX90380LDC-BAB-506-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SOIC-8 package mapping, X/Z magnetic axis configuration, programmable high-bandwidth mode, and validated alternatives for automotive-grade BLDC and PMSM rotor position feedback.
Technical Context
The MLX90380LDC-BAB-506-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using on-die integrated Hall elements and signal conditioning. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD, enabling direct interface with MCU ADCs without external reference.
This variant is factory-programmed for NdFeB magnet compatibility (BAB), X/Z magnetic axis (x3x suffix), 70 mT full-scale range (xx6), and high-bandwidth operation (x5x - 5V supply + high BW). Output update period is fixed at 4 µs, with tracking delay of 12 µs under high-bandwidth programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Dual ratiometric analog: OUT1 = COS, OUT2 = SIN, both referenced to VDD |
| Full-Scale Magnetic Range | 70 mT - enables robust sensing with NdFeB magnets in end-of-shaft or through-shaft configurations |
| Output Refresh Rate | 4 µs - supports real-time position tracking up to 25,000 rpm with ≤12 µs total tracking delay |
| Supply Voltage | 4.5–5.5 V - high-bandwidth mode requires 5 V supply; VDD3V3 pin must be left floating |
| Operating Temperature | -40°C to 150°C - qualified for under-hood automotive and industrial motor drive environments |
| Magnetic Axis | X/Z configuration - OUT1 responds to BX, OUT2 responds to BZ; optimized for off-axis two-pole magnet placement |
| Angular Accuracy | ±1° total error with dynamic compensation - achieved via external ECU offset/gain correction of raw sine/cosine outputs |
Pinout & Package
MLX90380LDC-BAB-506-SP is housed in a RoHS-compliant SOIC-8 package (body size 3.9 mm × 4.9 mm, 1.27 mm pitch), designed for surface-mount assembly and high-temperature reflow. Unused pins (NC) and TEST must be connected to ground for optimal EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VSS | Supply Ground | Primary ground reference for internal circuitry and output stage; must be low-impedance |
| 2, 4 - NC | Not Connected | No internal connection; tie to GND per EMC recommendation |
| 3 - TEST | Test Pin | Factory test access; tie to GND for production operation |
| 5 - OUT2 | Analog Output SIN | Ratiometric voltage proportional to BZ; drives MCU ADC input directly |
| 6 - VDD5V | 5 V Supply Input | Active power rail for high-bandwidth operation; VDD3V3 must remain floating |
| 7 - VDD3V3 | 3.3 V Supply Input | Unused in this variant; must be left floating to avoid supply conflict |
| 8 - OUT1 | Analog Output COS | Ratiometric voltage proportional to BX; paired with OUT2 for arctan(OUT2/OUT1) angle calculation |
Key Features
| Feature | Design Value |
|---|---|
| Selectable X/Z magnetic axis | Enables mechanical flexibility for off-axis two-pole magnet mounting in through-shaft motor designs |
| NdFeB magnet optimization (BAB) | Factory-tuned sensitivity and temperature coefficient for neodymium-iron-boron magnets across -40°C to 150°C |
| 70 mT full-scale range (xx6) | Maximizes signal-to-noise ratio and angular resolution in high-field motor applications with compact magnets |
| High-bandwidth 5 V operation (x5x) | Delivers 4 µs output update and 12 µs tracking delay - critical for field-oriented control at >15,000 rpm |
| Ratiometric analog outputs | Eliminates need for external voltage reference; maintains accuracy across VDD tolerance and PCB trace resistance |
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 |
|---|---|---|---|
| MLX90380LDC-BAB-504-SP | Same SOIC-8 package, NdFeB magnet (BAB), X/Z axis (x3x), but 50 mT full-scale range (xx4) and same 5V/high-BW mode | Lower magnetic range reduces sensitivity margin in high-temperature or low-magnet-strength environments | Select when magnet field strength is stable and known to stay within 50 mT; offers tighter linearity (±0.5%) at reduced range |
| MLX90380LGO-BAB-506-SP | TSSOP-16 dual-die redundant package, identical BAB-506 programming (NdFeB, X/Z, 70 mT, 5V/high-BW), but with functional safety support | Required for ASIL-B/C automotive systems needing fault detection and cross-die comparison | Choose for ISO 26262-compliant motor control where redundancy and diagnostic coverage are mandatory |
Compared with MLX90380LDC-BAB-506-SP, the BAB-504 variant trades magnetic headroom for improved linearity at lower fields, while the LGO-BAB-506 provides hardware-level redundancy at the cost of larger footprint and higher BOM cost - making the LDC version optimal for cost-sensitive, non-safety-critical high-speed BLDC applications.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-506-SP?
The MLX90380LDC-BAB-506-SP is factory-programmed for X/Z magnetic axis operation, meaning OUT1 (COS) responds to the X-axis magnetic field component and OUT2 (SIN) responds to the Z-axis component. This configuration is optimized for off-axis two-pole magnet placement in through-shaft motor assemblies, as confirmed by its BAB-506 option code (x3x suffix).
Does MLX90380LDC-BAB-506-SP support both 3.3 V and 5 V supply voltages?
No - MLX90380LDC-BAB-506-SP is programmed for high-bandwidth operation with a 5 V supply (x5x suffix), requiring VDD5V to be powered at 4.5–5.5 V. The VDD3V3 pin must remain floating; connecting it risks supply conflict and malfunction. This is explicitly defined in the ordering code structure and verified in Section 13.1.2 of the datasheet.
What is the full-scale magnetic range and magnet type compatibility for MLX90380LDC-BAB-506-SP?
The MLX90380LDC-BAB-506-SP has a 70 mT full-scale magnetic range (xx6 suffix) and is optimized for NdFeB (neodymium-iron-boron) magnets (BAB prefix). This combination ensures matched sensitivity temperature coefficient and signal integrity across -40°C to 150°C, as specified in Table 2 and Section 12 of the datasheet.
How does the 4 µs output refresh rate translate to real-time motor control performance?
The 4 µs output refresh rate of MLX90380LDC-BAB-506-SP enables position updates at 250 kHz, supporting accurate angle tracking up to 25,000 rpm with only 12 µs total tracking delay under high-bandwidth programming. This allows tight field-oriented control loop timing in high-dynamic PMSM and BLDC applications without interpolation.
Can MLX90380LDC-BAB-506-SP be used without external microcontroller compensation?
MLX90380LDC-BAB-506-SP delivers raw sine/cosine outputs requiring external signal processing - typically in an MCU - to compute arctan(OUT2/OUT1) and apply offset, gain, and phase corrections. Total angular error is ±1° only after such dynamic compensation; uncorrected error exceeds ±10°, as stated in Table 8 of the datasheet.
