Product details
Overview
MLX90380LDC-BAB-003-RE from Melexis is a monolithic Triaxis® Hall-based resolver IC delivering true 360° contactless angular position sensing via ratiometric sine/cosine analog outputs. 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 magnet compatibility, 30mT full-scale magnetic range, X/Y magnetic axis, and high-bandwidth operation. It serves as the core position feedback element in brushless motor rotor angle acquisition.
For engineers reviewing the MLX90380LDC-BAB-003-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, SOIC-8 package mapping, real-world motor control use cases, and validated alternative options aligned with automotive and industrial BLDC/PMSM designs.
Technical Context
The MLX90380LDC-BAB-003-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) magnetic field components using integrated vertical and planar Hall elements. Its dual analog outputs deliver synchronized, ratiometric sine and cosine signals referenced to VDD, enabling high-fidelity arctangent-based angle computation by an external MCU ADC.
This variant is preconfigured for X/Y axis sensitivity matching, 30mT full-scale range, NdFeB magnet optimization, and high-bandwidth mode-yielding 125kHz Nyquist frequency and 12µs tracking delay. Internal chopping at 1MHz suppresses offset drift, while programmable filter bandwidth and EEPROM-based calibration support system-level accuracy tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time rotor position capture at up to 25,000 RPM without interpolation. |
| Operating Supply | 3.3V or 5V - Dual-rail support allows direct interface with 3.3V MCUs or legacy 5V systems; VDD3V3/VDD5V pins are mutually exclusive. |
| Full-Scale Magnetic Range | 30 mT - Factory-set sensitivity optimized for NdFeB magnets in end-of-shaft configurations with ±40% VDD output swing. |
| Temperature Range | -40°C to +150°C - Qualified for under-hood automotive and industrial motor drive environments without derating. |
| Output Linearity | ±0.5% - Measured over 0.5–4.5V (5V mode) or 0.33–2.97V (3.3V mode), enabling <1° electrical angle error before compensation. |
| Tracking Delay | 12 µs - Fixed latency between magnetic stimulus change and updated SIN/COS outputs in high-bandwidth mode. |
| Total Angular Error (uncorrected) | ±10° at 25°C - Represents raw sensor linearity limit; reduced to ±1° with dynamic ECU-side offset/gain/phase correction. |
Pinout & Package
MLX90380LDC-BAB-003-RE is housed in a RoHS-compliant SOIC-8 package (5.3mm × 6.2mm × 1.75mm body, 1.27mm pitch). Unused pins (NC) and TEST must be connected to ground for optimal EMC performance. VDD3V3 must float in 5V-mode applications per Melexis design guidance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VSS | Supply Ground | Main power return path; connects to PCB ground plane for low-noise analog reference. |
| 2 NC | Not Connected | Internally unconnected; must be tied to GND per EMC recommendation. |
| 3 TEST | Test Pin | Factory test access; requires GND connection during normal operation to suppress noise coupling. |
| 4 NC | Not Connected | Internally unconnected; must be tied to GND per EMC recommendation. |
| 5 OUT2 | Analog Output SIN | Ratiometric voltage proportional to sin(θ); 0–100% VDD swing, 25Ω output impedance. |
| 6 VDD5V | 5V Supply Input | Active 5V rail; VDD3V3 must remain floating when this pin is powered. |
| 7 VDD3V3 | 3.3V Supply Input | Active 3.3V rail; VDD5V must remain floating when this pin is powered. |
| 8 OUT1 | Analog Output COS | Ratiometric voltage proportional to cos(θ); synchronized with OUT2, same output specs. |
Key Features
| Feature | Design Value |
|---|---|
| Selectable Magnetic Axis (X/Y) | Enables precise alignment with end-of-shaft permanent magnet assemblies without mechanical reorientation. |
| NdFeB Magnet Optimization (BAB) | Factory-tuned sensitivity and temperature coefficient for neodymium-iron-boron magnets across -40°C to 150°C. |
| High-Bandwidth Mode | Delivers 125kHz Nyquist frequency and 12µs tracking delay-critical for field-oriented control at >10k RPM. |
| Ratiometric Outputs | SIN/COS voltages scale directly with VDD, eliminating need for separate voltage reference in MCU ADC circuits. |
| Programmable via Connector | EEPROM configuration (sensitivity, axis, bandwidth) performed in-system using standard 4-pin interface-no dedicated programmer required. |

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-003-RE?
The MLX90380LDC-BAB-003-RE is factory-programmed for X/Y magnetic axis configuration, meaning OUT1 responds to the BX field component and OUT2 to the BY component with matched sensitivity. This enables direct integration with end-of-shaft two-pole magnets where the field rotates in-plane relative to the IC surface. The option code "BAB-003" confirms X/Y axis selection per Melexis ordering documentation.
Does MLX90380LDC-BAB-003-RE support both 3.3V and 5V supply simultaneously?
No, MLX90380LDC-BAB-003-RE does not support simultaneous 3.3V and 5V supply. It operates exclusively from either VDD3V3 (3.135–3.6V) or VDD5V (4.5–5.5V), with the unused supply pin left floating. The datasheet explicitly states that connecting both rails invalidates operation and may damage the device. The "003" suffix indicates high-bandwidth mode, which is available for both supply voltages but requires correct rail selection per application diagram.
What is the significance of the "BAB" in MLX90380LDC-BAB-003-RE?
The "BAB" segment of MLX90380LDC-BAB-003-RE identifies the magnet material optimization: "BA" denotes standard Triaxis® configuration, and "B" specifies NdFeB (neodymium-iron-boron) magnet compatibility. This determines the factory-programmed sensitivity temperature coefficient (TCS ≈ 1100 ppm/°C) and full-scale range calibration-ensuring optimal linearity and thermal stability when paired with NdFeB magnets in automotive and industrial motor applications.
Can MLX90380LDC-BAB-003-RE be reprogrammed in-system?
Yes, MLX90380LDC-BAB-003-RE supports in-system programming via its 4-pin interface (VDD, VSS, TEST, and one output pin used as bidirectional communication line). Customers can adjust parameters including magnetic axis, sensitivity range, bandwidth, and output offset using Melexis' PSF software and standard microcontroller GPIOs-no dedicated programmer is required. Factory programming remains intact unless explicitly overwritten.
What is the maximum rotational speed MLX90380LDC-BAB-003-RE can accurately resolve?
MLX90380LDC-BAB-003-RE supports accurate angular position resolution up to 25,000 RPM when operating in high-bandwidth mode. At this speed, its 4µs output refresh rate yields 1.6 samples per mechanical degree, and its 125kHz Nyquist frequency prevents aliasing. Total angular error remains within ±1° after dynamic ECU-side compensation, making it suitable for high-speed PMSM and BLDC applications such as electric powertrain inverters and industrial spindles.
