Product details
Overview
MLX90380LDC-BAA-100-RE from Melexis is a monolithic Triaxis® contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs with 4 µs output refresh rate, 3.3 V or 5 V supply operation, and -40°C to 150°C operating temperature range. It functions as a resolver replacement in end-of-shaft or through-shaft motor position feedback systems for brushless DC and PMSM motors.
For engineers reviewing the MLX90380LDC-BAA-100-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package mapping, magnetic axis configuration (X/Y), 40 mT full-scale range, ratiometric analog outputs, and real-world motor control design implications - all confirmed from Melexis Revision 11 datasheet (June 2021).
Technical Context
The MLX90380LDC-BAA-100-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) magnetic field components using integrated planar and vertical Hall elements. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD and deliver ±40% VDD swing at full scale, enabling direct interface with MCU ADCs without external scaling.
This variant is factory-programmed for X/Y magnetic axis, 40 mT full-scale range, SmCo magnet compatibility, and high-bandwidth mode (4 µs update period). It supports both 3.3 V and 5 V supply configurations via dedicated VDD3V3 and VDD5V pins, with internal power-on reset thresholds of 2.4–3.4 V (3.3 V mode) or 2.7–3.9 V (5 V mode).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angular tracking up to 25,000 rpm with ≤12 µs total tracking delay in high-bandwidth mode. |
| Full-Scale Magnetic Range | 40 mT - Factory-programmed sensitivity yields ±40% VDD output swing at BX/BY = ±40 mT (TA = 25°C, VDD = nominal). |
| Operating Supply | 3.3 V or 5 V - Dual-supply pin architecture (VDD3V3/VDD5V) allows flexible MCU interface; only one supply active per use case. |
| Temperature Range | -40°C to 150°C - Qualified for under-hood automotive and industrial motor control environments without derating. |
| Magnetic Axis | X/Y - Configured for end-of-shaft or on-axis multi-pole magnet applications; OUT1 = COS(BX), OUT2 = SIN(BY). |
| Output Type | Ratiometric analog - Output voltage scales linearly with VDD; eliminates need for reference voltage matching in ADC acquisition. |
| Total Angular Error | ±10° (uncorrected), ±1° (with dynamic compensation) - Accuracy achievable via off-chip arctan(OUT2/OUT1) with offset/gain correction. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VSS | Supply Ground | Primary ground reference for analog and digital circuitry; must be low-impedance connection to system GND plane. |
| 2 NC | Not Connected | Internally unconnected; requires PCB trace to GND for EMC compliance per datasheet recommendation. |
| 3 TEST | Test Pin | Factory test access; must be tied to GND in final design to prevent noise coupling and ensure stable operation. |
| 4 NC | Not Connected | Internally unconnected; requires PCB trace to GND for EMC compliance per datasheet recommendation. |
| 5 OUT2 | Analog Output SIN | Sine waveform output referenced to VDD; ratiometric, ±40% VDD swing at full scale; interfaces directly to 12-bit+ MCU ADC. |
| 6 VDD5V | 5 V Supply Input | Active when using 5 V supply; VDD3V3 must remain floating in this configuration per Section 9.1 and Figure 13. |
| 7 VDD3V3 | 3.3 V Supply Input | Active when using 3.3 V supply; VDD5V must remain floating in this configuration per Section 9.1 and Figure 12. |
| 8 OUT1 | Analog Output COS | Cosine waveform output referenced to VDD; ratiometric, ±40% VDD swing at full scale; paired with OUT2 for angle computation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Y) field measurement enables true 360° absolute angle resolution without mechanical commutation or interpolation. |
| Selectable Magnetic Axis | X/Y configuration supports end-of-shaft mounting with two-pole magnets or on-axis multi-pole arrangements - no re-design needed for shaft topology change. |
| Programmable Sensitivity Range | 40 mT full-scale (BAA-100) optimizes ADC utilization for SmCo magnets while maintaining linearity error < ±0.5% over 0.5–4.5 V output range. |
| Ratiometric Analog Outputs | Eliminates need for precision voltage references; output scaling tracks VDD variations, simplifying signal chain design and improving system robustness. |
| High-Speed Update | 4 µs output period supports closed-loop FOC motor control at >20 kHz current loop rates with minimal latency-induced phase lag. |
Applications
| Brushless Motor Rotor Position | PMSM Field-Oriented Control |
|---|---|

Use Scenario: Angular measurement across hollow motor shafts in traction inverters or robotic joint actuators requiring center-bore magnet placement. IC Role / Device Role / Timing Role: Z/Y-axis configurable variant (not this part) supports through-shaft; BAA-100's X/Y axis is optimized for end-of-shaft but compatible with off-axis multi-pole layouts. Use Value: Programmable magnetic axis selection allows single BOM to support both end-of-shaft and through-shaft mechanical variants via firmware configuration - no hardware change required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LDC-BAB-100-RE | Uses NdFeB magnet instead of SmCo; identical X/Y axis, 40 mT range, SOIC-8, and 4 µs update rate. | Lower cost magnet material; higher sensitivity temperature coefficient (1100 ppm/°C vs. 350 ppm/°C) requires tighter thermal management. | Select when NdFeB magnet geometry and thermal profile are validated; avoid in high-temperature gradient environments without compensation. |
| MLX90380LGO-BAA-100-RE | TSSOP-16 dual-die redundant package; same X/Y axis, 40 mT range, and 4 µs update, but with independent die A/B outputs. | ASIL-D capable via hardware redundancy; larger footprint (5 × 4.4 mm) and separate ground/supply pins per die increase layout complexity. | Select for automotive functional safety applications requiring fault-tolerant position reporting; not drop-in compatible due to pin count and package size. |
Compared with MLX90380LDC-BAA-100-RE, the BAB-100 variant trades thermal stability for cost-sensitive NdFeB compatibility, while the LGO-BAA-100-RE adds ASIL-D readiness at the expense of PCB area and routing overhead - neither is pin-compatible, but all three share identical signal processing requirements and MCU interface logic.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAA-100-RE?
The MLX90380LDC-BAA-100-RE is factory-programmed for X/Y magnetic axis configuration, meaning OUT1 responds to the BX field component and OUT2 to the BY component. This supports end-of-shaft mounting with two-pole magnets or on-axis multi-pole arrangements, as defined by option code BAA-100 in Table 2 of the datasheet.
Does MLX90380LDC-BAA-100-RE support both 3.3 V and 5 V supplies simultaneously?
No - MLX90380LDC-BAA-100-RE uses separate VDD3V3 and VDD5V pins, but only one supply may be active at a time. When using 3.3 V, VDD5V must be left floating; when using 5 V, VDD3V3 must be left floating. This isolation prevents cross-conduction and ensures correct internal biasing per Section 9.1 and Figures 12–13.
What is the full-scale magnetic range and sensitivity of MLX90380LDC-BAA-100-RE?
MLX90380LDC-BAA-100-RE has a factory-programmed full-scale magnetic range of 40 mT, yielding ±40% VDD output swing (e.g., 1.32–1.98 V at 3.3 V supply) with linearity better than ±0.5% over the central 90% of the output range, as specified in Table 7 and Table 8 of the datasheet.
Can MLX90380LDC-BAA-100-RE be used in through-shaft applications?
MLX90380LDC-BAA-100-RE is optimized for X/Y axis and end-of-shaft use, but its datasheet confirms compatibility with off-axis multi-pole magnet configurations typical in some through-shaft layouts. For dedicated through-shaft operation with Z/Y or X/Z axes, variants like MLX90380LDC-BAB-023-RE or MLX90380LGO-BAA-100-RE are recommended per Section 8.3 and Table 2.
What is the maximum rotational speed supported by MLX90380LDC-BAA-100-RE?
MLX90380LDC-BAA-100-RE supports up to 25,000 rpm with ≤12 µs total tracking delay in high-bandwidth mode. At this speed, it delivers 1.6 samples per degree of rotation, enabling accurate closed-loop control in high-performance BLDC and PMSM motor applications as verified in Table 8's "Magnetic Angular Speed" specification.
