Product details
Overview
MLX90380LDC-BAB-200-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, -40°C to 150°C operating temperature, and factory-programmed NdFeB magnet sensitivity for 3.3 V supply at high bandwidth. It serves as the primary angle transducer in brushless motor rotor position feedback loops.
For engineers reviewing the MLX90380LDC-BAB-200-SP datasheet, pinout, applications, or equivalent options, this page delivers verified SOIC-8 pin definitions, magnetic axis configuration (X/Z), 30 mT full-scale range, high-bandwidth timing behavior, and validated alternatives for automotive and industrial motor control designs.
Technical Context
The MLX90380LDC-BAB-200-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) 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.
Programmable filter bandwidth (high BW mode), selectable magnetic axis (X/Z), and factory-set 30 mT full-scale range (BAB-200) are configured at production. The device supports both end-of-shaft and through-shaft magnet arrangements and operates with either 3.3 V or 5 V supply-though BAB-200 specifies 3.3 V high-bandwidth operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - enables real-time position tracking up to 25,000 rpm with ≤12 µs total tracking delay in high-bandwidth mode. |
| Full-Scale Magnetic Range | 30 mT - factory-programmed for NdFeB magnets, optimized for signal-to-noise ratio and ADC utilization in 3.3 V systems. |
| Operating Supply | 3.3 V nominal (VDD3V3 = 3.135–3.6 V) - VDD5V must be left floating; ensures compatibility with low-voltage MCU ADC references. |
| Magnetic Axis | X/Z configuration - OUT1 measures BX, OUT2 measures BZ; supports off-axis through-shaft applications with 50% BZ/BXY sensitivity mismatch. |
| Temperature Range | -40°C to +150°C - qualified for under-hood automotive and industrial motor drive environments without derating. |
| Output Type | Ratiometric sine/cosine analog - output voltage scales linearly with VDD (±40% VDD swing), eliminating supply-induced angle error. |
| Total Angular Error | ±1° with dynamic compensation - achievable via external ECU offset/gain/phase correction prior to arctan(OUT2/OUT1). |
Pinout & Package
MLX90380LDC-BAB-200-SP is housed in an industry-standard SOIC-8 package (5.3 mm × 6.2 mm, 1.27 mm pitch), RoHS-compliant, with exposed pad optional per variant. Pin 1 is VSS (ground); pins 2 and 4 are NC; pin 3 is TEST; pins 5 and 8 are analog outputs; pins 6 and 7 are dedicated supply inputs.
| 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. |
| 2 NC | Not Connected | No internal connection; recommended to tie to GND for EMC performance. |
| 3 TEST | Factory Test Interface | Used during wafer sort and final test; tie to GND in application for optimal EMC. |
| 4 NC | Not Connected | No internal connection; recommended to tie to GND for EMC performance. |
| 5 OUT2 | Analog Output SIN | Delivers ratiometric sine waveform proportional to BZ; requires 10 kΩ–∞ load and ≤10 nF capacitance for stability. |
| 6 VDD5V | 5 V Supply Input | Must remain floating when using 3.3 V operation (BAB-200); not connected in this configuration. |
| 7 VDD3V3 | 3.3 V Supply Input | Active supply rail for BAB-200; accepts 3.135–3.6 V; powers all internal circuitry including Hall sensors and analog front-end. |
| 8 OUT1 | Analog Output COS | Delivers ratiometric cosine waveform proportional to BX; matches OUT2 timing and noise profile for coherent angle calculation. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-die assemblies. |
| Programmable High Bandwidth | 4 µs update period and 125 kHz Nyquist frequency support closed-loop FOC at >20 kHz PWM carrier frequencies. |
| NdFeB Magnet Optimization | BAB-200 option configures sensitivity for neodymium magnets, maximizing SNR and linearity across -40°C to 150°C. |
| Ratiometric Outputs | Sine/cosine outputs scale with VDD, removing supply ripple and tolerance effects from angle computation accuracy. |
| End-of-Shaft / Through-Shaft Flexibility | X/Z axis selection enables mechanical integration with both on-axis (end-of-shaft) and off-axis (through-shaft) magnet placements. |
Applications
| Brushless DC Motor Rotor Position | Permanent Magnet Synchronous Motor 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-BAB-100-RE | Same SOIC-8 package and NdFeB magnet tuning, but medium bandwidth (2 µs per component, 29.5 µs tracking delay) and 10 mT full-scale range. | Better suited for lower-speed motors (<8,000 rpm) where SNR at low field strength outweighs latency needs. | Select BAB-100 when optimizing for sensitivity in weak-field or low-RPM applications; BAB-200 prioritizes speed and dynamic response. |
| MLX90380LGO-BAB-023-RE | TSSOP-16 dual-die redundant architecture, same BAB-023 NdFeB/30 mT/high-BW configuration, but with independent die A/B outputs and enhanced fault detection. | Required for ASIL-D or SIL-3 safety-critical systems needing hardware redundancy and cross-die diagnostics. | Choose LGO-BAB-023 only when functional safety certification mandates dual-channel independence; BAB-200 suffices for ASIL-B or non-safety designs. |
Compared with MLX90380LDC-BAB-100-RE, the MLX90380LDC-BAB-200-SP trades lower magnetic sensitivity for higher update rate and wider usable RPM range; versus MLX90380LGO-BAB-023-RE, it offers cost and board-space savings at the expense of hardware-level redundancy.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-200-SP?
The MLX90380LDC-BAB-200-SP is factory-programmed for X/Z magnetic axis configuration, meaning OUT1 responds to the X-axis magnetic field component and OUT2 to the Z-axis component. This supports through-shaft magnet arrangements with inherent 50% sensitivity mismatch between axes, as defined in option code BAB-200 per Melexis documentation.
Does MLX90380LDC-BAB-200-SP require both 3.3 V and 5 V supplies?
No. The MLX90380LDC-BAB-200-SP operates exclusively from the 3.3 V supply (VDD3V3) and requires VDD5V to be left floating. This is mandated by its BAB-200 option code, which specifies 3.3 V high-bandwidth operation; connecting 5 V to VDD5V will cause malfunction.
What is the full-scale magnetic range and sensitivity of MLX90380LDC-BAB-200-SP?
The MLX90380LDC-BAB-200-SP has a factory-programmed full-scale magnetic range of 30 mT for NdFeB magnets. Its sensitivity is approximately 1.33 %VDD/mT (66.5 mV/mT at 3.3 V), delivering ±40% VDD output swing (1.32 V to 1.98 V) across the full magnetic range at 25°C.
Can MLX90380LDC-BAB-200-SP be used in ASIL-B automotive systems?
Yes. The MLX90380LDC-BAB-200-SP is AEC-Q100 qualified for Grade 0 (-40°C to +150°C), features built-in diagnostics (e.g., supply monitoring, output short-circuit detection), and supports dynamic angle error compensation-enabling compliance with ASIL-B requirements for EPS and transmission control when integrated into a properly architected safety framework.
How does the 4 µs output refresh rate translate to maximum rotational speed capability?
With a 4 µs output refresh period and ≤12 µs total tracking delay in high-bandwidth mode, the MLX90380LDC-BAB-200-SP supports accurate position capture up to 25,000 rpm. At that speed, the mechanical angle changes by ~0.15° between updates, preserving fidelity for FOC and commutation algorithms requiring sub-degree resolution.
