Product details
Overview
MLX90380LGO-BAB-400-SP from Melexis is a dual-die, fully redundant Triaxis® resolver IC delivering true 360° sine/cosine analog outputs for absolute rotary position sensing. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4 µs output refresh rate, and is factory-programmed for NdFeB magnet compatibility with 50 mT full-scale magnetic range and X/Z magnetic axis configuration.
For engineers reviewing the MLX90380LGO-BAB-400-SP datasheet, pinout, applications, or equivalent options, this device serves as a high-reliability angular position sensor in safety-critical motor control systems where redundancy, wide temperature operation, and contactless sensing are mandatory.
Technical Context
The MLX90380LGO-BAB-400-SP integrates two independent monolithic Triaxis® sensor dies in a single TSSOP-16 package, each with dedicated VDD/VSS/OUT/TEST pins and programmable magnetic axis (X/Z), sensitivity (50 mT), and bandwidth (high). Its dual-die architecture enables fault-tolerant operation via external comparison logic or ASIL-D–capable MCU arbitration.
It delivers ratiometric analog outputs (OUT1 = COS, OUT2 = SIN) proportional to orthogonal magnetic field components, with 1.6 samples/degree at 25,000 rpm and ≤12 µs tracking delay under high-bandwidth programming - enabling precise real-time angle reconstruction in PMSM and BLDC field-oriented control loops.
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 with X/Z axis alignment per BAB option code |
| Output Refresh Rate | 4 µs - enables 250 kSPS sampling for high-speed rotor tracking up to 25,000 rpm |
| Operating Supply | 3.3V or 5V - dual-supply pins (VDD3V3_A/B, VDD5V_A/B) allow mixed-voltage system integration |
| Temperature Range | -40°C to +150°C - qualified for under-hood automotive and industrial motor drive environments |
| Package | TSSOP-16 - surface-mount, dual-die layout with isolated power/ground domains per die |
| Angular Accuracy | ±1° total error with dynamic compensation - supports closed-loop FOC requiring sub-degree precision |
Pinout & Package
TSSOP-16 package with dual-die redundancy: separate power, ground, output, and test pins for Die A and Die B ensure functional isolation and fault detection capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Independent ground returns for Die A and Die B - mandatory separation prevents coupling-induced errors |
| 5, 13 | OUT2_B / OUT2_A | SIN output channels - used for arctan(OUT2/OUT1) angle calculation on each die |
| 8, 16 | OUT1_B / OUT1_A | COS output channels - paired with respective OUT2 for orthogonal field component resolution |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs - support high-SNR operation; VDD3V3 must be left floating when using 5V mode |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs - enable low-power operation; VDD5V must be left floating when using 3.3V mode |
| 4, 11 | TEST_A / TEST_B | Factory test and programming access - tied to GND for optimal EMC per datasheet recommendation |
| 2, 3, 10, 12 | NC | No-connect pins - must be connected to ground for EMI suppression and thermal stability |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Independent signal chains (Die A + Die B) enable ASIL-D–compliant fault detection and cross-checking |
| Programmable X/Z magnetic axis | Supports through-shaft configurations with two-pole off-axis magnets - eliminates mechanical alignment constraints |
| High-bandwidth output | 12 µs tracking delay and 4 µs update period - preserves phase integrity at >20,000 rpm motor speeds |
| NdFeB-optimized 50 mT range | Matches common high-energy permanent magnet flux densities - maximizes ADC utilization without external gain |
| Ratiometric analog outputs | Output swing scales with VDD - rejects supply ripple and simplifies interface to 3.3V/5V ADCs |

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-100-RE | Same dual-die TSSOP-16 package and NdFeB magnet support, but configured for 10 mT range and low bandwidth (74 µs tracking delay). | Targeted at low-speed, high-accuracy applications like robotic encoders where bandwidth is secondary to offset stability. | Select when motor speed < 5,000 rpm and ultra-low temperature drift (< ±0.5%VDD) is prioritized over update rate. |
| MLX90380LDC-BAB-400-RE | Single-die SOIC-8 variant with identical 50 mT range, X/Z axis, and high bandwidth - lacks dual-die redundancy. | Suitable for non-safety-critical BLDC fans or pumps where cost and board space constrain redundancy requirements. | Choose when ASIL compliance is not required and PCB area is limited; same magnetic calibration and programming interface apply. |
Compared with MLX90380LGO-BAB-100-RE, the MLX90380LGO-BAB-400-SP delivers 6× faster tracking (12 µs vs. 74 µs) for high-dynamic applications; versus MLX90380LDC-BAB-400-RE, it adds hardware-level fault tolerance via physically isolated signal paths - critical for automotive EPS and traction inverters.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-400-SP?
The MLX90380LGO-BAB-400-SP is factory-programmed for X/Z magnetic axis configuration, meaning OUT1 reports the Z-axis magnetic component and OUT2 reports the X-axis component. This supports through-shaft magnet arrangements with two-pole off-axis magnets and enables mechanical flexibility in motor assembly.
Does MLX90380LGO-BAB-400-SP support both 3.3V and 5V operation simultaneously?
No - MLX90380LGO-BAB-400-SP requires exclusive use of either VDD3V3 or VDD5V per die. When operating at 5V, VDD3V3 pins must be left floating; when operating at 3.3V, VDD5V pins must be left floating. Each die has independent supply pins to maintain isolation between redundant channels.
How is redundancy implemented in MLX90380LGO-BAB-400-SP?
Redundancy is implemented via two physically independent Triaxis® sensor dies in one TSSOP-16 package, each with dedicated VDD/VSS/OUT/TEST pins and isolated signal paths. This allows external comparison logic or dual-core MCU arbitration to detect faults such as open-circuit, short-to-rail, or parametric drift in either channel.
What is the full-scale magnetic range of MLX90380LGO-BAB-400-SP and which magnet type does it target?
The MLX90380LGO-BAB-400-SP has a 50 mT full-scale magnetic range and is programmed for NdFeB (Neodymium Iron Boron) magnets, as indicated by the "BAB" option code. This range optimizes signal-to-noise ratio and ADC utilization for common high-energy permanent magnets used in automotive and industrial motors.
Can MLX90380LGO-BAB-400-SP be reprogrammed after soldering?
No - MLX90380LGO-BAB-400-SP is factory-programmed during final test and cannot be reconfigured in-system. Programming parameters - including magnetic axis (X/Z), sensitivity range (50 mT), and bandwidth (high) - are permanently stored in laser-fused EEPROM and inaccessible post-shipment.
