Product details
Overview
MLX90380LDC-BAC-000-RE 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, -40°C to 150°C operating range, and factory-programmed ferrite-magnet sensitivity (70 mT full-scale range) in SOIC-8 package for end-of-shaft motor rotor position feedback.
For engineers reviewing the MLX90380LDC-BAC-000-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 pin mapping, magnetic axis configuration (X/Y), and real-world motor control integration details - all confirmed against Melexis Revision 11 datasheet and ordering code definitions.
Technical Context
The MLX90380LDC-BAC-000-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) magnetic field components using on-die integrated Hall elements and signal conditioning circuitry. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD and deliver synchronized 360° angle data without interpolation.
This variant uses ferrite magnets (BAC option code), supports both 3.3 V and 5 V supply operation (VDD3V3/VDD5V pins), and features programmable bandwidth via external filter configuration - enabling optimization of tracking delay (12–85.5 µs) and noise performance for BLDC or PMSM field-oriented control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Ratiometric analog sine/cosine outputs referenced to VDD; enables direct ADC interfacing without external reference voltage. |
| Refresh Rate | 4 µs per field component (2 µs per axis); supports up to 25,000 RPM mechanical rotation with <1° total angular error after dynamic compensation. |
| Full-Scale Range | 70 mT (BAC-xxx option code); optimized for ferrite magnets in cost-sensitive automotive and industrial motor applications. |
| Operating Temp | -40°C to +150°C; qualified for under-hood and inverter-integrated motor control environments. |
| Supply Voltage | Supports dual-rail operation: 3.135–3.6 V (VDD3V3) or 4.5–5.5 V (VDD5V); unused rail must be left floating per datasheet. |
| Magnetic Axis | X/Y configuration (BAC-000); delivers equal sensitivity on X and Y axes for end-of-shaft two-pole magnet mounting. |
| Linearity Error | ±0.5% over 360° at VDD=5 V (output within 0.5–4.5 V); ensures high-fidelity angle reconstruction before arctan processing. |
Pinout & Package
MLX90380LDC-BAC-000-RE is housed in a standard SOIC-8 package (JEDEC MS-012AC) with 1.27 mm pitch, 5.0 mm × 6.2 mm body, and exposed pad not present. Pin 1 is marked by notch or dot; pins 2 and 4 are NC and must be connected to GND for optimal EMC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VSS | Supply Ground | Main ground reference for analog and digital blocks; requires low-impedance connection to system GND plane. |
| 2 NC | Not Connected | Internally unconnected; must be tied to VSS for EMC compliance per datasheet Section 9.1. |
| 3 TEST | Test Pin | Factory test access; connect to VSS for normal operation and ESD robustness. |
| 4 NC | Not Connected | Internally unconnected; must be tied to VSS for EMC compliance per datasheet Section 9.1. |
| 5 OUT2 | Analog Output SIN | Sine waveform output (ratiometric to VDD); connects directly to MCU ADC input for angle computation. |
| 6 VDD5V | 5 V Supply Input | Active when 5 V operation selected; VDD3V3 must remain floating in this mode. |
| 7 VDD3V3 | 3.3 V Supply Input | Active when 3.3 V operation selected; VDD5V must remain floating in this mode. |
| 8 OUT1 | Analog Output COS | Cosine waveform output (ratiometric to VDD); paired with OUT2 for arctan(OUT2/OUT1) angle calculation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Y) field measurement eliminates need for external flux concentrators or multi-die assemblies. |
| Programmable Magnetic Axis | X/Y configuration (BAC-000) enables direct compatibility with end-of-shaft two-pole magnet layouts without mechanical reorientation. |
| Ferrite Magnet Optimization | BAC option code configures internal gain and TCS for stable 70 mT full-scale operation with low-cost ferrite magnets. |
| Ratiometric Outputs | Output swing scales linearly with VDD (e.g., ±40% VDD), removing dependency on precision voltage references in noisy motor drive environments. |
| High-Speed Update | 4 µs total output period supports real-time FOC loop closure at >20 kHz PWM frequencies with minimal latency. |
Applications
| Brushless Motor Rotor Position | PMSM Field-Oriented Control |

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-BAA-000-RE | SmCo magnet calibration (40 mT full-scale), higher TCS stability (350 ppm/°C vs. 2000 ppm/°C for ferrite). | Better thermal stability for high-precision applications above 100°C; requires SmCo magnet instead of ferrite. | Select BAA-000 if magnet cost is secondary to thermal drift minimization in premium motor control. |
| MLX90380LGO-BAC-000-RE | TSSOP-16 dual-die fully redundant architecture; separate VDD/GND per die; 1.5 kV CDM ESD rating. | Required for ASIL-D or dual-channel safety architectures; occupies larger PCB area and requires two independent signal paths. | Select LGO-BAC-000 only when functional safety certification mandates hardware redundancy. |
Compared with MLX90380LDC-BAC-000-RE, the BAA-000 offers tighter thermal drift but higher magnet cost, while the LGO-BAC-000 adds safety redundancy at the expense of size and layout complexity - making the BAC-000 optimal for cost-sensitive, non-redundant ferrite-based motor position sensing.

FAQ
What magnetic magnet type is required for MLX90380LDC-BAC-000-RE?
MLX90380LDC-BAC-000-RE is factory-programmed for ferrite magnets, as indicated by the "BAC" option code. It delivers 70 mT full-scale magnetic range and uses a 2000 ppm/°C sensitivity temperature coefficient optimized for ferrite's thermal demagnetization profile. Using SmCo or NdFeB magnets will result in reduced output swing and degraded accuracy without reprogramming.
Can MLX90380LDC-BAC-000-RE operate from both 3.3 V and 5 V supplies simultaneously?
No. MLX90380LDC-BAC-000-RE supports either 3.3 V (VDD3V3 pin) or 5 V (VDD5V pin), but not both concurrently. The unused supply pin must be left floating - connecting both rails risks undefined behavior and violates the Absolute Maximum Ratings table. Application diagrams in the datasheet show discrete 3.3 V or 5 V configurations.
What is the significance of the X/Y magnetic axis configuration in MLX90380LDC-BAC-000-RE?
The X/Y axis (BAC-000) means OUT1 responds to the X-axis magnetic field component and OUT2 to the Y-axis component, with equal sensitivity. This configuration is designed for end-of-shaft, two-pole magnet mounting where the magnet rotates parallel to the IC surface - enabling direct angular position extraction without mechanical adaptation or axis remapping in firmware.
How does the 4 µs output refresh rate translate to usable angular resolution at high speed?
The 4 µs refresh rate allows MLX90380LDC-BAC-000-RE to resolve mechanical rotation up to 25,000 RPM with <1° total angular error after dynamic compensation. At that speed, each 4 µs sample captures ~0.42° of mechanical rotation, supporting high-bandwidth FOC loops where position update latency directly impacts torque ripple and efficiency.
Is MLX90380LDC-BAC-000-RE pin-compatible with other MLX90380 variants in SOIC-8 package?
Yes. All SOIC-8 variants including MLX90380LDC-BAA-000-RE and MLX90380LDC-BAB-000-RE share identical pinout, package dimensions, and thermal characteristics. Only magnetic calibration (BAA/BAB/BAC), sensitivity range, and axis selection differ - allowing drop-in replacement at the board level when reprogramming or recalibration is performed.
