Product details
Overview
MLX90380LDC-BAB-043-SP from Melexis is a monolithic Triaxis® contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs for absolute angular measurement. It operates with 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4µs output refresh rate, and is factory-programmed for NdFeB magnet, 30mT full-scale magnetic range, X/Z magnetic axis, and high-bandwidth operation - used in brushless motor rotor position sensing for field-oriented control.
For engineers reviewing the MLX90380LDC-BAB-043-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package details, real-world motor control use cases, and validated alternative options for automotive and industrial BLDC/PMSM systems.
Technical Context
The MLX90380LDC-BAB-043-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using integrated planar and vertical Hall elements. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD and deliver synchronized 360° angle data with ≤1° total angular error after dynamic compensation.
This variant is preconfigured for NdFeB magnets, 30mT full-scale range, X/Z axis orientation, and high-bandwidth mode (5V supply, 125kHz Nyquist frequency), enabling accurate position tracking up to 25,000 rpm with 12µs tracking delay and 1.6 samples/degree at maximum speed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - enables real-time position feedback for high-speed motor commutation with minimal latency. |
| Operating Supply | 3.3V or 5V - dual-rail support allows direct interface with common MCU ADC reference voltages. |
| Temperature Range | -40°C to 150°C - qualified for under-hood automotive and industrial motor drive environments. |
| Magnetic Range | 30 mT - factory-set full-scale sensitivity optimized for NdFeB magnets in end-of-shaft configurations. |
| Magnetic Axis | X/Z - enables accurate sensing with off-axis two-pole magnets in through-shaft applications. |
| Bandwidth Mode | High - 125 kHz Nyquist frequency and 12 µs tracking delay support >25,000 rpm operation. |
| Total Angular Error | ±1° with dynamic compensation - achievable via external ECU offset/gain correction of sine/cosine outputs. |

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-023-SP | Same SOIC-8 package and NdFeB magnet option, but configured for medium bandwidth (3.3V supply) and 20mT range. | Suitable for lower-speed motors (<15,000 rpm) where reduced bandwidth lowers system noise and simplifies filtering. | Select when 3.3V supply is mandatory and target magnetic field strength is lower; requires revalidation of signal-to-noise ratio. |
| MLX90380LGO-BAB-043-SP | TSSOP-16 dual-die redundant package with identical magnetic programming (NdFeB, 30mT, X/Z, high BW), but includes full functional redundancy. | Required for ASIL-B/C automotive safety-critical applications where fault detection and fail-operational capability are mandated. | Choose for ISO 26262-compliant systems; adds PCB area and cost but enables diagnostic coverage unavailable in SOIC-8 variants. |
Compared with MLX90380LDC-BAB-023-SP, the MLX90380LDC-BAB-043-SP delivers higher speed capability and tighter magnetic range matching for NdFeB; versus MLX90380LGO-BAB-043-SP, it trades redundancy for smaller footprint and lower BOM cost in non-safety-critical motor control.

FAQ
What is the magnetic axis configuration of the MLX90380LDC-BAB-043-SP?
The MLX90380LDC-BAB-043-SP is factory-programmed for X/Z magnetic axis orientation, meaning OUT1 responds to the X-component and OUT2 to the Z-component of the applied magnetic field. This configuration supports through-shaft applications with two-pole magnets and enables accurate off-axis sensing without mechanical repositioning.
Does the MLX90380LDC-BAB-043-SP require external programming for operation?
No, the MLX90380LDC-BAB-043-SP ships fully programmed for NdFeB magnet type, 30mT full-scale range, X/Z axis, and high-bandwidth mode. It operates immediately upon power-up with 3.3V or 5V supply and requires no external EEPROM programming or configuration pins for basic functionality.
What is the maximum rotational speed supported by the MLX90380LDC-BAB-043-SP?
The MLX90380LDC-BAB-043-SP supports up to 25,000 rpm with high-bandwidth programming. At this speed, it delivers 1.6 samples per degree of rotation and maintains ≤12 µs tracking delay, enabling accurate field-oriented control in high-performance BLDC and PMSM motors.
How does the ratiometric output of the MLX90380LDC-BAB-043-SP improve system accuracy?
The MLX90380LDC-BAB-043-SP's ratiometric outputs (OUT1 and OUT2 scale proportionally with VDD) eliminate dependence on a separate precision voltage reference. When sampled by an MCU ADC using the same VDD as its reference, gain errors from supply variation cancel out - preserving angular accuracy across load and temperature.
Can the MLX90380LDC-BAB-043-SP be used with both 3.3V and 5V microcontrollers?
Yes, the MLX90380LDC-BAB-043-SP supports dual supply operation: either VDD3V3 (3.135–3.6 V) or VDD5V (4.5–5.5 V) may be powered, with the other supply pin left floating. Its ratiometric outputs ensure compatibility with both 3.3V and 5V ADC references without level-shifting circuitry.
