Product details
Overview
MLX90380LDC-BAB-000-RE 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 magnet compatibility with X/Y magnetic axis and 40mT full-scale range.
For engineers reviewing the MLX90380LDC-BAB-000-RE datasheet, pinout, applications, or equivalent options, this device serves as a high-accuracy, automotive-grade angular position transducer requiring no mechanical contact, supporting field-oriented control (FOC) in BLDC and PMSM motors with ratiometric analog interface to external ADCs.
Technical Context
The MLX90380LDC-BAB-000-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 (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD, enabling direct interfacing with microcontroller ADCs without external reference voltage.
Programmable sensitivity (40mT full-scale), magnetic axis selection (X/Y), and bandwidth configuration are set at factory via option code BAB-000. The SOIC-8 package integrates internal signal conditioning, chopping stabilization, and on-chip EEPROM for calibration data retention - all operating within AEC-Q100 Grade 0 temperature limits.

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 optimization (vs. NdFeB); identical X/Y axis, 40mT range, SOIC-8 package | Requires SmCo magnet assembly; higher cost magnet but improved temperature stability | Select when magnet temperature coefficient dominates system error budget over -40°C to +150°C |
| MLX90380LGO-BAB-000-RE | TSSOP-16 dual-die redundant architecture; same BAB-000 programming (NdFeB, X/Y, 40mT) | Provides functional redundancy for ASIL-D systems; requires larger PCB footprint and dual-supply routing | Select for safety-critical applications requiring fault-tolerant position reporting per ISO 26262 |
Compared with MLX90380LDC-BAB-000-RE, the BAA-000 variant trades NdFeB flexibility for SmCo thermal stability, while the LGO-BAB-000 offers hardware redundancy at the cost of layout complexity - neither is pin-compatible, but all share identical signal processing architecture and programming interface.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-000-RE?
The MLX90380LDC-BAB-000-RE is factory-programmed for X/Y magnetic axis operation, meaning OUT1 responds to the BX field component and OUT2 to the BY component. This configuration supports end-of-shaft mounting with standard two-pole magnets and enables direct 360° angle computation via arctan(OUT2/OUT1). The BAB option code explicitly defines this X/Y orientation.
Does MLX90380LDC-BAB-000-RE support both 3.3V and 5V supply rails simultaneously?
No - MLX90380LDC-BAB-000-RE supports either 3.3V or 5V operation, not both concurrently. When using VDD3V3 (pin 7), VDD5V (pin 6) must be left floating; conversely, when using VDD5V, VDD3V3 must float. This single-rail requirement is enforced by internal regulator architecture and prevents supply contention.
What is the full-scale magnetic range of MLX90380LDC-BAB-000-RE and how is it determined?
The MLX90380LDC-BAB-000-RE has a factory-programmed full-scale magnetic range of 40 mT for the X/Y axes. This value is encoded in the option code "BAB-000", where "000" specifies the 40mT sensitivity range. At this setting, a ±40 mT in-plane field produces ±40% VDD output swing around the 50% VDD quiescent level (VOQ), enabling optimal ADC utilization.
Can MLX90380LDC-BAB-000-RE be used in through-shaft configurations?
No - MLX90380LDC-BAB-000-RE is configured for X/Y magnetic axis, which is intended for end-of-shaft (on-axis) magnet placement. Through-shaft operation requires Z/Y or X/Z axis configurations (e.g., BAB-02x or BAB-04x variants) to sense axial field components. Using BAB-000 in through-shaft setups results in severely degraded signal amplitude and linearity.
What is the maximum rotational speed supported by MLX90380LDC-BAB-000-RE?
The MLX90380LDC-BAB-000-RE supports up to 25,000 RPM with high-bandwidth programming, delivering 1.6 samples per electrical degree at that speed. Its 4 µs per-output update rate (8 µs full SIN/COS pair) and <12 µs total tracking delay enable accurate real-time angle tracking in high-speed traction motors and servo spindles.
