Product details

Overview

MLX90380LGO-BAB-003-SP from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs. It operates from 3.3V or 5V supply, supports -40°C to 150°C ambient, features 4µs output refresh rate, and is factory-programmed for NdFeB magnet compatibility, X/Z magnetic axis configuration, and 30mT full-scale magnetic range. It serves as the core position feedback element in high-reliability brushless motor control systems.

For engineers reviewing the MLX90380LGO-BAB-003-SP datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, TSSOP-16 package details, magnetic axis behavior, real-world angular error performance, and validated alternative options for automotive and industrial motor control designs.

Technical Context

The MLX90380LGO-BAB-003-SP implements Triaxis® Hall technology with integrated signal conditioning to resolve orthogonal (X/Z) magnetic field components. Its dual-die TSSOP-16 architecture provides functional redundancy: Die A (pins 13–16) and Die B (pins 5–8) each deliver independent SIN/COS outputs with separate supply and ground terminals.

Factory programming fixes the magnetic axis to X/Z (equal sensitivity), full-scale range to 30mT, and magnet type to NdFeB. Output update timing is fixed at 4µs per field component (8µs total for both SIN and COS), with tracking delay of 29.5µs under medium bandwidth configuration-matching the BAB-003 option code's 3.3V/medium BW setting.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Refresh Rate	4 µs per field component; enables real-time position tracking up to 25,000 RPM with ≤29.5 µs system latency.
Operating Supply	3.3 V or 5 V; dual supply pins (VDD3V3_A/B, VDD5V_A/B) allow mixed-voltage system integration.
Full-Scale Magnetic Range	30 mT; optimized for NdFeB magnets in end-of-shaft or through-shaft configurations with X/Z axis alignment.
Angular Accuracy	±1° total error with dynamic compensation; ±15° uncorrected over -40°C to 150°C, enabling robust field-oriented control.
Output Type	Ratiometric sine/cosine analog outputs (OUT1 = COS, OUT2 = SIN); voltage swing scales directly with VDD for ADC interface resilience.
Temperature Range	-40°C to 150°C ambient; qualified for under-hood automotive and industrial motor drive environments.
Package	TSSOP-16; dual-die fully redundant layout with isolated power/ground domains per die for ASIL-B compliance support.

Pinout & Package

TSSOP-16 package with dual-die redundancy: two independent sensor dies (Die A and Die B), each with dedicated supply, ground, test, and analog output pins. Pin 1 is VSS_A (Ground Die A), pin 9 is VSS_B (Ground Die B); unused pins (2,3,10,12) must be tied to ground for EMC compliance.

Pin/Terminal	Circuit Role	Design Meaning
1, 9	VSS_A / VSS_B	Separate ground returns for Die A and Die B-prevents crosstalk and supports fault-isolated operation.
5, 13	OUT2_B / OUT2_A	SIN output channels for Die B and Die A; enable differential or redundant angle computation in safety-critical systems.
8, 16	OUT1_B / OUT1_A	COS output channels for Die B and Die A; paired with respective OUT2 pins to form complete sine/cosine pairs per die.
6, 14	VDD5V_B / VDD5V_A	5V supply inputs for Die B and Die A; used when operating at 5V; VDD3V3 pins must be left floating in this mode.
7, 15	VDD3V3_B / VDD3V3_A	3.3V supply inputs for Die B and Die A; used when operating at 3.3V; VDD5V pins must be left floating in this mode.
4, 11	TEST_A / TEST_B	Test pins for factory calibration and diagnostics; tied to ground in application for optimal EMC performance.

Key Features

Feature	Design Value
Triaxis® Hall Sensing	Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies.
Selectable Magnetic Axis	X/Z configuration enables compatibility with both end-of-shaft (two-pole) and through-shaft (multi-pole) magnet arrangements.
Dual-Die Redundancy	Independent Die A and Die B outputs support ASIL-B functional safety requirements via cross-checking or voting logic.
Ratiometric Outputs	Output voltage scales with VDD, eliminating gain drift errors when interfaced with ratiometric ADCs in motor control MCUs.
Programmable Bandwidth	Medium bandwidth mode (BAB-003) delivers 29.5 µs tracking delay-optimized for fast-response PMSM/BLDC commutation.

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-005-RE	Same TSSOP-16 package and NdFeB/X/Z configuration, but 60mT full-scale range and high-bandwidth mode (12.5 µs tracking delay).	Better suited for low-field, high-speed applications requiring faster response; not drop-in due to different bandwidth and sensitivity.	Select when magnet air gap varies widely or target speed exceeds 25,000 RPM-requires MCU firmware re-tuning for updated timing.
MLX90380LGO-BAA-000-RE	Same TSSOP-16 package but SmCo magnet compatibility, X/Y axis, and 40mT range; lacks NdFeB optimization and X/Z geometry.	Designed for end-of-shaft SmCo magnets only; incompatible with NdFeB-based through-shaft layouts used by MLX90380LGO-BAB-003-SP.	Choose only if migrating from legacy SmCo magnet systems; requires mechanical redesign to accommodate X/Y field orientation.

Compared with MLX90380LGO-BAB-003-SP, the BAB-005 offers higher speed at the cost of reduced magnetic sensitivity, while the BAA-000 requires different magnet material and mechanical mounting-neither is pin-compatible nor functionally interchangeable without system-level validation.

FAQ

What is the magnetic axis configuration of MLX90380LGO-BAB-003-SP?

The MLX90380LGO-BAB-003-SP is factory-programmed for X/Z magnetic axis configuration with equal sensitivity on both axes. This enables compatibility with through-shaft multi-pole magnet arrangements and specific end-of-shaft geometries where orthogonal field components are required. The X/Z axis selection is encoded in the "BAB" option code and cannot be changed in-system.

Does MLX90380LGO-BAB-003-SP support both 3.3V and 5V operation simultaneously?

No-MLX90380LGO-BAB-003-SP supports either 3.3V or 5V operation, not both simultaneously. When using 3.3V, connect VDD3V3_A/B and leave VDD5V_A/B floating; when using 5V, connect VDD5V_A/B and leave VDD3V3_A/B floating. The BAB-003 variant is configured for 3.3V medium-bandwidth operation per its ordering code definition.

How does the dual-die TSSOP-16 architecture improve reliability in MLX90380LGO-BAB-003-SP?

The dual-die TSSOP-16 layout in MLX90380LGO-BAB-003-SP provides physical redundancy: Die A (pins 13–16) and Die B (pins 5–8) operate independently with separate power, ground, and output paths. This allows cross-checking of angle results or voting-based fault detection-critical for ASIL-B automotive systems where single-point failures must be detected and mitigated.

What is the full-scale magnetic range of MLX90380LGO-BAB-003-SP and why does it matter?

The MLX90380LGO-BAB-003-SP has a factory-programmed full-scale magnetic range of 30 mT, optimized for NdFeB magnets. This value defines the in-plane flux density that produces ±40% VDD output swing. Selecting the correct range ensures maximum ADC utilization and minimizes quantization error-using a mismatched range (e.g., 60 mT magnet with 30 mT device) degrades effective resolution and linearity.

Can MLX90380LGO-BAB-003-SP be used with ferrite or SmCo magnets?

No-MLX90380LGO-BAB-003-SP is specifically programmed for NdFeB magnets, as indicated by the "BAB" prefix in its option code. Using ferrite or SmCo magnets will result in incorrect sensitivity scaling and degraded angular accuracy. For SmCo, select BAA-coded variants; for ferrite, choose BAC-coded variants-each requires matching magnet material and recalibration.
