Product details
Overview
MLX90380LDC-BAB-504-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 resolves angular position using NdFeB magnets in end-of-shaft or through-shaft configurations for brushless motor control systems.
For engineers reviewing the MLX90380LDC-BAB-504-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SOIC-8 package mapping, magnetic axis (X/Z), 50 mT full-scale range, ratiometric analog outputs, and field-oriented control design guidance.
Technical Context
The MLX90380LDC-BAB-504-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components, enabling precise angular computation via arctangent of analog SIN/COS outputs. Its dual-die architecture is not used here-this variant is single-die SOIC-8 with X/Z magnetic axis configuration and factory-programmed 50 mT full-scale range for NdFeB magnets.
It supports programmable bandwidth (high BW mode), delivers ratiometric outputs referenced to VDD, and features on-chip signal conditioning including chopping at 1 MHz and sample-and-hold filtering. Output tracking delay is 12 µs in high-bandwidth mode, and linearity error is ≤ ±0.5% over specified voltage and temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Dual ratiometric analog: OUT1 = COS, OUT2 = SIN, both referenced to VDD |
| Full-Scale Magnetic Range | 50 mT - optimized for NdFeB magnets in X/Z axis configuration |
| Output Refresh Rate | 4 µs - enables real-time angular tracking up to 25,000 rpm |
| Supply Voltage | 3.135–3.6 V or 4.5–5.5 V - supports dual-rail operation with VDD3V3/VDD5V pins |
| Operating Temperature | -40°C to +150°C - qualified for under-hood automotive and industrial motor environments |
| Angular Accuracy | ±1° total error with dynamic compensation - after system-level offset/gain correction |
| Magnetic Axis | X/Z - OUT1 responds to BX, OUT2 responds to BZ; supports through-shaft magnet mounting |
Pinout & Package
MLX90380LDC-BAB-504-RE is housed in an 8-pin SOIC-8 package (3.9 mm × 4.9 mm, 1.27 mm pitch) with exposed pad for thermal performance and EMC robustness.
| Pin/Terminal | Circuit Role | Design Meaning |

| 3 TEST | Factory Test Pin | Used during wafer test; tie to GND for optimal EMC in final design |
| 4 NC | Not Connected | No internal connection; recommended to tie to GND for EMC |
| 5 OUT2 | Analog Output SIN | Sine output referenced to VDD; drives ADC input directly with ratiometric scaling |
| 6 VDD5V | 5 V Supply Input | Active when 5 V operation selected; VDD3V3 must float in this mode |
| 7 VDD3V3 | 3.3 V Supply Input | Active when 3.3 V operation selected; VDD5V must float in this mode |
| 8 OUT1 | Analog Output COS | Cosine output referenced to VDD; paired with OUT2 for arctan-based angle calculation |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies |
| Programmable Magnetic Axis | X/Z configuration enables compatibility with off-axis through-shaft magnet arrangements without mechanical rework |
| Ratiometric Analog Outputs | OUT1/OUT2 scale linearly with VDD, removing sensitivity to supply rail variation in noisy motor drive environments |

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-504-RE | Same SOIC-8 package and 50 mT range, but uses SmCo magnet instead of NdFeB; higher TCS (350 ppm/°C vs. 1100 ppm/°C) | Better high-temperature stability above 125°C; less suitable for cost-sensitive NdFeB-based designs | Select BAA-504-RE only if magnet material is SmCo and thermal drift budget requires lower TCS. |
| MLX90380LGO-BAB-005-RE | TSSOP-16 dual-die redundant package; identical X/Z axis and 30 mT range (not 50 mT); higher ESD rating (1.5 kV CDM vs. 0.5 kV) | Designed for ASIL-D functional safety systems requiring hardware redundancy; larger footprint and different pinout | Choose LGO-BAB-005-RE only when ISO 26262 ASIL-D compliance mandates dual-die fault tolerance. |
Compared with MLX90380LDC-BAB-504-RE, the BAA-504-RE variant trades NdFeB compatibility for improved thermal coefficient matching, while the LGO-BAB-005-RE sacrifices size and magnetic range for hardware redundancy-neither is pin-compatible or drop-in replaceable.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAB-504-RE?
The MLX90380LDC-BAB-504-RE is factory-programmed for X/Z magnetic axis configuration, meaning OUT1 responds to the X-axis magnetic field component and OUT2 responds to the Z-axis component. This supports through-shaft magnet mounting where the field vector has orthogonal in-plane and axial components, and is confirmed by the 'BAB' option code's third digit '5' indicating X/Z axis with high-bandwidth programming.
What does the '504' in MLX90380LDC-BAB-504-RE signify?
The '504' suffix in MLX90380LDC-BAB-504-RE decodes as follows: '5' selects X/Z magnetic axis, '0' selects 3.3 V supply voltage, and '4' selects high bandwidth mode. The 'BAB' prefix confirms NdFeB magnet compatibility and 50 mT full-scale magnetic range, making MLX90380LDC-BAB-504-RE a 3.3 V, high-BW, X/Z-axis, NdFeB-optimized variant in SOIC-8.
Can MLX90380LDC-BAB-504-RE operate from a 5 V supply?
No-MLX90380LDC-BAB-504-RE is configured for 3.3 V operation only, as indicated by the '0' in the '504' option code. Attempting to apply 5 V to VDD5V while leaving VDD3V3 unconnected violates the recommended application diagram and may cause undefined behavior. For 5 V operation, select a part with '1', '3', or '5' as the second digit (e.g., MLX90380LDC-BAB-514-RE).
What is the output update latency of MLX90380LDC-BAB-504-RE?
The MLX90380LDC-BAB-504-RE has a 4 µs output update period and a 12 µs tracking delay in high-bandwidth mode (as specified by the '4' in '504'). This means the time between a change in magnetic angle and corresponding change on both OUT1 and OUT2 is 12 µs, enabling accurate position capture at rotational speeds up to 25,000 rpm in field-oriented control loops.
Is MLX90380LDC-BAB-504-RE pin-compatible with other MLX90380 variants in SOIC-8?
Yes-MLX90380LDC-BAB-504-RE shares identical SOIC-8 pinout and package dimensions with all other SOIC-8 MLX90380 variants (e.g., BAA-xxx, BAC-xxx). Pin functions (VSS, VDD3V3, VDD5V, OUT1, OUT2, TEST, NC) remain consistent across variants; only magnetic axis, sensitivity, supply voltage, and bandwidth are factory-programmed and do not affect physical connectivity.
