Product details
Overview
MLX90380LDC-BAB-003-SP from Melexis is a monolithic Triaxis® contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs for resolver replacement in motor control systems. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4µs output refresh rate, and is factory-programmed for NdFeB magnets with 30mT full-scale magnetic range and X/Y magnetic axis configuration.
For engineers reviewing the MLX90380LDC-BAB-003-SP datasheet, pinout, applications, or equivalent options, this device serves as a high-accuracy, automotive-grade angular position transducer requiring no mechanical contact, supporting end-of-shaft and through-shaft magnet arrangements with programmable bandwidth and ratiometric analog outputs compatible with standard ADC inputs.
Technical Context
The MLX90380LDC-BAB-003-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) magnetic field components using integrated vertical and planar Hall elements. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD, enabling direct interface with microcontroller ADCs without external reference scaling.
This SOIC-8 variant uses a single-die architecture with dedicated VDD3V3 and VDD5V supply pins, internal chopping at 1 MHz, and programmable sample-and-hold filter bandwidth-here configured for high-bandwidth operation (4 µs update period, 125 kHz Nyquist frequency) per BAB-003 option code.

| 7 VDD3V3 | 3.3V Supply Input | Active when operating at 3.3V; VDD5V must remain floating in this mode |
| 8 OUT1 | Analog Output COS | Ratiometric voltage proportional to cos(θ); complementary to OUT2 for arctan-based angle computation |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Sensing Architecture | Simultaneous orthogonal X/Y field measurement via integrated vertical+planar Hall elements eliminates need for external flux concentrators or multi-chip assemblies |

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-003-SP?
The MLX90380LDC-BAB-003-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 supports end-of-shaft two-pole magnet arrangements and enables direct cosine/sine output generation without external coordinate transformation in the MLX90380LDC-BAB-003-SP.
Can MLX90380LDC-BAB-003-SP operate from both 3.3V and 5V supplies simultaneously?
No. The MLX90380LDC-BAB-003-SP has separate VDD3V3 and VDD5V pins; only one supply voltage may be active at a time. When using 3.3V, VDD5V must be left floating; when using 5V, VDD3V3 must be left floating. This isolation prevents cross-conduction and ensures correct internal biasing in the MLX90380LDC-BAB-003-SP.
What is the full-scale magnetic range programmed in MLX90380LDC-BAB-003-SP?
The MLX90380LDC-BAB-003-SP is programmed for a 30 mT full-scale magnetic range (option code BAB-003), optimized for NdFeB magnets. At this setting, a ±30 mT in-plane field produces a ±40% VDD output swing with 50% VDD quiescent level, enabling optimal ADC utilization in the MLX90380LDC-BAB-003-SP.
How does the 4 µs output refresh rate impact motor control loop performance?
The 4 µs output refresh rate (250 kSPS) of the MLX90380LDC-BAB-003-SP enables sub-microsecond position updates, supporting current loop bandwidths exceeding 10 kHz in PMSM and BLDC motor control. This timing allows real-time field-oriented control at speeds up to 25,000 rpm with minimal latency in the MLX90380LDC-BAB-003-SP signal chain.
Is MLX90380LDC-BAB-003-SP qualified for automotive applications?
Yes. The MLX90380LDC-BAB-003-SP is AEC-Q100 Grade 0 qualified (-40°C to +150°C), features 2 kV HBM ESD protection, and meets automotive EMC requirements. Its SOIC-8 package and Triaxis® architecture are validated for powertrain, steering, and transmission use cases where resolver replacement is needed in the MLX90380LDC-BAB-003-SP.
