Product details
Overview
MLX90380LDC-BAB-005-SP from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, 3.3 V/5 V dual-supply support, -40°C to 150°C operating range, and factory-programmed NdFeB magnet sensitivity for 60 mT full-scale magnetic range.
For engineers reviewing the MLX90380LDC-BAB-005-SP datasheet, pinout, applications, or equivalent options, this device serves as a high-accuracy, automotive-grade rotary position sensor in brushless motor control, field-oriented control, and end-of-shaft or through-shaft configurations requiring robust thermal stability and programmable magnetic axis selection (X/Z).
Technical Context
The MLX90380LDC-BAB-005-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) and parallel magnetic field components on a single die, enabling precise angle computation via arctan(OUT2/OUT1). Its dual analog outputs are ratiometric to supply voltage and feature programmable filter bandwidth via external pins.
This SOIC-8 variant uses X/Z magnetic axis configuration with sensitivity mismatch compensation, supports high-bandwidth operation (125 kHz Nyquist), and delivers ≤1° total angular error with dynamic compensation-optimized for permanent magnet synchronous motors and BLDC systems operating up to 25,000 rpm.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time position tracking at up to 25,000 rpm without interpolation delay. |
| Full-Scale Magnetic Range | 60 mT - Factory-programmed for NdFeB magnets; sets ±40%VDD output swing at TA = 25°C. |
| Magnetic Axis | X/Z - COS on OUT1 (X-axis), SIN on OUT2 (Z-axis); supports through-shaft off-axis mounting. |
| Supply Voltage | 3.135–3.6 V or 4.5–5.5 V - Dual-rail support; VDD3V3 and VDD5V pins must be used separately per application diagram. |
| Operating Temperature | -40°C to 150°C - Qualified for under-hood automotive and industrial motor control environments. |
| Total Angular Error | ±1° with dynamic compensation - Achieved via external ECU offset/gain correction applied pre-arctan. |
| Output Linearity | ±0.5% - Valid over 0.5–4.5 V (5 V supply) or 0.33–2.97 V (3.3 V supply), enabling direct ADC interfacing. |
Pinout & Package
MLX90380LDC-BAB-005-SP is housed in an 8-pin SOIC package (body width 3.9 mm, lead pitch 1.27 mm), RoHS-compliant, with exposed pad optional for thermal enhancement. 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 analog and digital circuitry; connects to system GND plane. |
| 2 NC | Not Connected | Internally unconnected; must be tied to GND per EMC guidelines. |
| 3 TEST | Test Pin | Factory test access; requires GND connection in final design to suppress noise coupling. |
| 4 NC | Not Connected | Internally unconnected; must be tied to GND per EMC guidelines. |
| 5 OUT2 | Analog Output SIN | Z-axis component output; ratiometric to VDD; drives ADC input directly with ≤25 Ω source impedance. |
| 6 VDD5V | 5 V Supply Input | Power rail for 5 V operation; VDD3V3 must remain floating when using this pin. |
| 7 VDD3V3 | 3.3 V Supply Input | Power rail for 3.3 V operation; VDD5V must remain floating when using this pin. |
| 8 OUT1 | Analog Output COS | X-axis component output; ratiometric to VDD; paired with OUT2 for arctan-based angle calculation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement on single die eliminates mechanical alignment of multiple sensors. |
| Ratiometric Sine/Cosine Outputs | Outputs scale linearly with supply voltage, removing need for precision voltage references in MCU ADC path. |
| Programmable Filter Bandwidth | Configurable via external pins to match motor speed and ADC sampling rate-supports low/medium/high BW modes. |
| End-of-Shaft / Through-Shaft Flexibility | X/Z axis configuration enables compatibility with both on-axis (end-of-shaft) and off-axis (through-shaft) magnet placements. |
| Factory Calibration Option | Optional end-of-line calibration available to reduce total angular error below ±1° in production systems. |
Applications
| Brushless DC Motor Control | Permanent Magnet Synchronous Motor |

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-003-SP | Same SOIC-8 package and X/Z axis, but 30 mT full-scale range for lower-strength NdFeB magnets. | Better suited for compact magnet geometries or reduced air gaps where field strength is limited. | Select when magnet flux density is constrained below 45 mT; retains identical pinout and programming interface. |
| MLX90380LGO-BAB-005-SP | TSSOP-16 dual-die fully redundant package; same 60 mT range and X/Z axis, but with independent die A/B outputs. | Required for ASIL-D functional safety architectures needing hardware redundancy and cross-check capability. | Choose for safety-critical automotive systems; not pin-compatible due to 16-pin layout and separate ground/power per die. |
Compared with MLX90380LDC-BAB-003-SP, the MLX90380LDC-BAB-005-SP provides higher magnetic range headroom for robustness against magnet aging and misalignment; versus MLX90380LGO-BAB-005-SP, it trades redundancy for smaller footprint and lower BOM cost in non-safety applications.

FAQ
What magnetic axis configuration does MLX90380LDC-BAB-005-SP use?
The MLX90380LDC-BAB-005-SP uses the X/Z magnetic axis configuration, where OUT1 carries the COS signal proportional to the X-axis magnetic field and OUT2 carries the SIN signal proportional to the Z-axis field. This supports through-shaft off-axis mounting and is factory-programmed per the BAB option code.
Does MLX90380LDC-BAB-005-SP support both 3.3 V and 5 V supply rails simultaneously?
No, MLX90380LDC-BAB-005-SP does not support simultaneous 3.3 V and 5 V operation. It operates exclusively on either VDD3V3 (3.135–3.6 V) or VDD5V (4.5–5.5 V); the unused supply pin must be left floating per the application diagrams in the datasheet.
What is the full-scale magnetic range of MLX90380LDC-BAB-005-SP and how is it set?
The MLX90380LDC-BAB-005-SP has a factory-programmed full-scale magnetic range of 60 mT for NdFeB magnets. This setting is encoded in the option code "005" and determines the sensitivity (≈0.66 %VDD/mT at 5 V), resulting in ±40%VDD output swing at 25°C with zero field offset.
Can MLX90380LDC-BAB-005-SP be used in safety-critical automotive applications like EPS?
Yes, MLX90380LDC-BAB-005-SP is AEC-Q100 qualified (Grade 0, -40°C to 150°C), features ratiometric outputs for robustness against supply variation, and supports dynamic angular error compensation. For ASIL-B systems it is suitable as a primary sensor; ASIL-D requires the redundant TSSOP-16 variant (e.g., MLX90380LGO-BAB-005-SP).
How is the output update rate of MLX90380LDC-BAB-005-SP achieved and what is its impact on motor control?
The MLX90380LDC-BAB-005-SP achieves a 4 µs output update period by sequentially measuring X and Z field components in 2 µs each. This enables real-time position tracking at up to 25,000 rpm, minimizing phase lag in high-speed FOC loops and supporting accurate torque estimation without interpolation.
