Product details
Overview
MLX90380LDC-BAA-100-SP 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, 3.3 V/5 V dual-supply support, -40°C to 150°C operating range, and X/Y magnetic axis configuration for end-of-shaft applications in brushless motor control.
For engineers reviewing the MLX90380LDC-BAA-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package details, magnetic axis selection, sensitivity programming, and real-world motor control integration guidance.
Technical Context
The MLX90380LDC-BAA-100-SP 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 in real time.
It supports factory-programmed magnetic sensitivity (40 mT full-scale range per BAA-100 coding), selectable bandwidth modes (low/medium/high), and on-chip dynamic compensation for offset and gain drift. The device operates with either 3.3 V or 5 V supply, with dedicated VDD3V3 and VDD5V pins and internal power-on reset circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time position tracking up to 25,000 rpm with <74 µs total tracking delay in high-bandwidth mode. |
| Operating Supply | 3.135–3.6 V or 4.5–5.5 V - Dual-rail support allows direct interface with 3.3 V or 5 V MCUs without level shifting. |
| Magnetic Axis | X/Y - Delivers COS on OUT1 and SIN on OUT2 for standard end-of-shaft configurations with two-pole magnets. |
| Full-Scale Range | 40 mT - Factory-programmed sensitivity (BAA-100) yields ±40% VDD output swing at 25°C, optimized for SmCo magnets. |
| Temperature Range | -40°C to +150°C - Qualified for under-hood automotive and industrial motor control environments. |
| Output Linearity | ±0.5% - Measured over 0.5–4.5 V (5 V supply) or 0.33–2.97 V (3.3 V supply), supporting high-accuracy closed-loop FOC. |
| Total Angular Error | ±1° with dynamic compensation - Achievable via external ECU correction of offset, amplitude, and phase prior to arctan(OUT2/OUT1). |
Pinout & Package
MLX90380LDC-BAA-100-SP is housed in an 8-pin SOIC-8 package (RoHS-compliant, JEDEC MS-012AC), with exposed pad option not specified. Pin 1 is VSS (ground); pins 2 and 4 are NC (not connected); pin 3 is TEST (to be grounded for EMC); pins 5 and 8 are analog outputs (OUT2/SIN and OUT1/COS); pins 6 and 7 are dedicated supply rails (VDD5V and VDD3V3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VSS | Supply Ground | Primary ground reference for analog and digital circuitry; must be low-impedance connection. |
| 2 NC | Not Connected | No internal connection; recommended to tie to ground for optimal EMC performance. |
| 3 TEST | Test Pin | Factory test access; externally grounded to reduce noise coupling and improve immunity. |
| 4 NC | Not Connected | No internal connection; recommended to tie to ground for optimal EMC performance. |
| 5 OUT2 | Analog Output SIN | Ratiometric voltage proportional to BY field component; used with OUT1 for arctan angle calculation. |
| 6 VDD5V | 5 V Supply Rail | Active when 5 V operation selected; VDD3V3 must remain floating in this mode. |
| 7 VDD3V3 | 3.3 V Supply Rail | Active when 3.3 V operation selected; VDD5V must remain floating in this mode. |
| 8 OUT1 | Analog Output COS | Ratiometric voltage proportional to BX field component; paired with OUT2 for full 360° resolution. |
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 Sensitivity | Factory-set 40 mT full-scale range (BAA-100) ensures optimal ADC utilization with SmCo magnets across temperature. |
| Selectably Configured Bandwidth | Three programmable filter settings (low/medium/high) allow trade-off between noise rejection and response latency per system requirements. |
| Ratiometric Outputs | OUT1 and OUT2 scale linearly with VDD, eliminating sensitivity to supply rail variation in noisy motor drive environments. |
| End-of-Shaft Operation | X/Y axis configuration supports compact, axial mounting directly on rotating shafts with standard two-pole permanent magnets. |

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-100-SP | Uses NdFeB magnet instead of SmCo; higher sensitivity temperature coefficient (1100 ppm/°C vs. 350 ppm/°C). | Better suited for cost-sensitive applications where magnet type is fixed to NdFeB and wider TCS tolerance is acceptable. | Select when magnet material is NdFeB and thermal drift budget allows higher TCS; same SOIC-8 footprint and pinout. |
| MLX90380LGO-BAA-100-SP | Dual-die TSSOP-16 package with full redundancy; separate VDD/GND per die; higher ESD robustness (1.5 kV CDM). | Required for ASIL-D or SIL-3 safety-critical systems needing hardware redundancy and fault detection capability. | Choose for functional safety designs requiring dual-channel independence; not pin-compatible due to TSSOP-16 packaging. |
Compared with MLX90380LDC-BAA-100-SP, the BAB-100 variant offers lower-cost magnet compatibility but reduced thermal stability, while the LGO-BAA-100-SP delivers safety-grade redundancy at the expense of board area and layout complexity.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAA-100-SP?
The MLX90380LDC-BAA-100-SP is configured for X/Y magnetic axis operation, meaning OUT1 (COS) responds to the BX field component and OUT2 (SIN) to the BY component. This enables direct compatibility with end-of-shaft, two-pole magnet setups where the magnetic field lies in-plane with the IC surface. The BAA-100 option code explicitly defines this X/Y orientation.
Can MLX90380LDC-BAA-100-SP operate from both 3.3 V and 5 V supplies?
Yes, MLX90380LDC-BAA-100-SP supports dual-supply operation: it accepts either 3.135–3.6 V on VDD3V3 or 4.5–5.5 V on VDD5V. Only one supply rail should be powered at a time-VDD3V3 must float during 5 V operation, and VDD5V must float during 3.3 V operation. Both configurations deliver ratiometric analog outputs scaled to the active VDD.
What is the full-scale magnetic range programmed in MLX90380LDC-BAA-100-SP?
The MLX90380LDC-BAA-100-SP is factory-programmed for a 40 mT full-scale magnetic range, corresponding to the "xx0" suffix in the option code. At 25°C and nominal VDD, this yields a ±40% VDD output swing (e.g., 1.65 V ± 0.66 V on a 3.3 V rail) with VOQ centered at 50% VDD, optimized for SmCo magnets.
How does MLX90380LDC-BAA-100-SP achieve high-speed angular updates?
MLX90380LDC-BAA-100-SP achieves a 4 µs output refresh period by sequentially sampling each field component in 2 µs intervals using high-speed chopper-stabilized Hall front-ends and integrated sample-and-hold circuits. This enables real-time position tracking up to 25,000 rpm with minimal latency, supporting demanding FOC and servo applications.
Is MLX90380LDC-BAA-100-SP qualified for automotive use?
Yes, MLX90380LDC-BAA-100-SP is AEC-Q100 qualified for Grade 0 (-40°C to +150°C), features RoHS-compliant SOIC-8 packaging, and meets automotive EMC and ESD requirements-including 2 kV HBM and 500 V CDM ratings. Its design targets EPS, transmission, and e-axle applications where reliability under thermal stress and vibration is critical.
