Product details
Overview
MLX90380LGO-BAB-005-SP from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, 3.3 V/5 V dual-supply support, and operation from −40 °C to +150 °C. It interfaces directly with rotating permanent magnets in end-of-shaft or through-shaft configurations for high-accuracy motor commutation.
For engineers reviewing the MLX90380LGO-BAB-005-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package mapping, magnetic axis configuration (X/Z), NdFeB magnet compatibility, 60 mT full-scale range, and high-bandwidth programming mode - all confirmed for the TSSOP-16 dual-die redundant variant.
Technical Context
The MLX90380LGO-BAB-005-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components, generating synchronized COS and SIN analog outputs referenced to VDD. Its dual-die TSSOP-16 architecture provides functional redundancy for safety-critical automotive and industrial applications.
Programmable sensitivity (60 mT range), X/Z magnetic axis selection, and high-bandwidth mode (4 µs update period, 125 kHz Nyquist frequency) are factory-set per BAB-005 option code. Output offset is stabilized at 50% VDD with ±2.5% ratiometry and <±1.5° total angular error after dynamic compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - enables real-time rotor angle tracking up to 25,000 rpm with ≤12 µs total tracking delay in high-bandwidth mode. |
| Full-Scale Magnetic Range | 60 mT - factory-programmed sensitivity for NdFeB magnets, optimized for robust signal-to-noise ratio in noisy motor environments. |
| Magnetic Axis Configuration | X/Z - OUT1 measures BX, OUT2 measures BZ; supports off-axis through-shaft mounting with 50% BZ/BXY sensitivity mismatch. |
| Supply Voltage Support | 3.3 V and 5 V - dual-rail operation; VDD3V3 and VDD5V pins are independent, allowing flexible MCU interface voltage matching. |
| Operating Temperature | −40 °C to +150 °C - qualified for under-hood automotive and industrial motor control where thermal stability is critical. |
| Total Angular Error | ±1° with dynamic compensation - achievable using external ECU-based offset/gain/phase correction prior to arctan(OUT2/OUT1). |
| Package | TSSOP-16 - dual-die fully redundant layout with separate ground, supply, and output pins per die for ASIL-D capable systems. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: two independent sensor dies (Die A and Die B), each with dedicated power, ground, test, and analog output pins. Pin assignment ensures EMC robustness - unused pins and TEST pins must be connected to ground.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns per die - prevents crosstalk and supports fault-isolation in redundant architectures. |
| 4, 11 | TEST_A / TEST_B | Factory test access; must be grounded in application for optimal EMC and noise immunity. |
| 5, 13 | OUT2_B / OUT2_A | SIN analog outputs - ratiometric to respective VDD rail; require 1–10 kΩ load and ≤2.2 nF capacitance for stability. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs - used when operating in 5 V mode; VDD3V3 pins must remain floating. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs - used when operating in 3.3 V mode; VDD5V pins must remain floating. |
| 8, 16 | OUT1_B / OUT1_A | COS analog outputs - paired with OUT2 for arctangent angle computation; matched gain/offset within die. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies. |
| Ratiometric Sine/Cosine Outputs | Outputs scale linearly with VDD, removing dependency on absolute supply accuracy and simplifying ADC reference design. |
| Programmable High-Bandwidth Mode | 4 µs update period enables >25,000 rpm motor speed sensing without interpolation or aliasing artifacts. |
| NdFeB Magnet Optimization | BAB-005 option configures 60 mT full-scale range and X/Z axis alignment specifically for neodymium-based magnets. |
| Dual-Die Redundancy | TSSOP-16 layout provides physically isolated signal paths for each die - supports diagnostic comparison and fail-safe operation. |
Applications
| Brushless Motor Commutation | Electric Power Steering (EPS) |

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 |
|---|---|---|---|
| MLX90380LGO-BAB-003-RE | Same TSSOP-16 dual-die package and X/Z axis, but 30 mT full-scale range and medium-bandwidth mode (29.5 µs tracking delay). | Better suited for lower-speed motors (<10,000 rpm) or systems prioritizing lower output noise over update speed. | Select when magnetic field strength is lower or when reduced bandwidth suffices for control loop timing. |
| MLX90380LGO-BAB-015-RE | Identical package and X/Z axis, but 15 mT full-scale range and high-bandwidth mode - optimized for ferrite magnets at 5 V supply. | Designed for cost-sensitive applications using low-coercivity magnets; requires tighter mechanical tolerances due to reduced range. | Choose only if system uses 5 V supply and ferrite magnets; not interchangeable with BAB-005's NdFeB-optimized 60 mT range. |
Compared with MLX90380LGO-BAB-003-RE and MLX90380LGO-BAB-015-RE, the MLX90380LGO-BAB-005-SP delivers the highest magnetic range (60 mT) and fastest update rate (4 µs) among BAB-coded TSSOP-16 variants, making it optimal for high-dynamic BLDC/PMSM control with NdFeB magnets.

FAQ
What is the magnetic axis configuration of the MLX90380LGO-BAB-005-SP?
The MLX90380LGO-BAB-005-SP is configured for X/Z magnetic axis operation, meaning OUT1 measures the BX component and OUT2 measures the BZ component. This configuration supports through-shaft mounting with inherent 50% sensitivity mismatch between Z and XY axes, as defined in the BAB-005 option code.
Does the MLX90380LGO-BAB-005-SP support both 3.3 V and 5 V supply voltages simultaneously?
No - the MLX90380LGO-BAB-005-SP operates on either 3.3 V or 5 V, not both simultaneously. When using VDD5V pins, the VDD3V3 pins must be left floating; conversely, when using VDD3V3, the VDD5V pins must be unconnected. The device detects supply mode automatically.
What is the significance of the "BAB" prefix in MLX90380LGO-BAB-005-SP?
The "BAB" prefix in MLX90380LGO-BAB-005-SP indicates NdFeB (neodymium-iron-boron) magnet compatibility and specifies X/Z magnetic axis orientation. The "005" suffix denotes 60 mT full-scale magnetic range and high-bandwidth programming mode - all factory-programmed and verified for this exact part number.
How does the dual-die TSSOP-16 package of MLX90380LGO-BAB-005-SP improve functional safety?
The dual-die TSSOP-16 package of MLX90380LGO-BAB-005-SP provides physically independent signal chains (Die A and Die B), enabling cross-die comparison for fault detection. Each die has dedicated VSS, VDD, TEST, and analog output pins - supporting ASIL-D diagnostic coverage without external redundancy circuitry.
Can the MLX90380LGO-BAB-005-SP be reprogrammed in-system?
No - the MLX90380LGO-BAB-005-SP is factory-programmed with fixed parameters: X/Z axis, 60 mT range, NdFeB magnet calibration, and high-bandwidth mode. Programming is performed during final test; the TEST pins are for factory diagnostics only and do not support user reconfiguration in the field.
