Product details
Overview
MLX90380LGO-BAB-043-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, 30mT full-scale range, and high-bandwidth mode. Used in end-of-shaft and through-shaft BLDC motor rotor position feedback.
For engineers reviewing the MLX90380LGO-BAB-043-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TSSOP-16 package details, magnetic axis configuration, bandwidth and sensitivity settings, and real-world motor control integration guidance - all specific to the BAB-043 variant.
Technical Context
The MLX90380LGO-BAB-043-SP implements Triaxis® Hall technology with integrated signal conditioning to resolve orthogonal (X/Z) magnetic field components using two independent die in a fully redundant TSSOP-16 package. Its dual-die architecture delivers independent COS and SIN outputs per die (OUT1_A/OUT2_A and OUT1_B/OUT2_B), enabling functional safety compliance in ASIL-B/C systems.
This variant is preconfigured for NdFeB magnets (BAB prefix), X/Z intrinsic magnetic axis (third digit '0' in '043'), 30mT full-scale range ('043' → 'x43' = 30mT), and high-bandwidth operation ('043' → '0xx' = 3.3V + high BW). Output tracking delay is 12 µs, and it supports dynamic compensation to reduce total angular error to ±1°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables >25,000 rpm rotor speed tracking with 1.6 samples/degree at max speed. |
| 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 - Factory-set for optimal ADC utilization with NdFeB magnets in X/Z axis configuration. |
| Temperature Range | -40°C to +150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Output Type | Ratiometric sine/cosine analog - Outputs scale with VDD; enables robust angle computation via arctan(OUT2/OUT1) without reference voltage dependency. |
| Bandwidth Mode | High - Achieves 12 µs tracking delay and 125 kHz Nyquist frequency for fast transient response. |
| Angular Accuracy | ±1° with dynamic compensation - Requires external ECU-based offset/gain/phase correction applied pre-arctan. |
Pinout & Package
TSSOP-16 package with exposed thermal pad (RoHS-compliant); dual-die layout provides redundancy across two independent sensor channels (Die A and Die B).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Dedicated ground returns per die - critical for noise isolation and EMC performance in redundant configurations. |
| 5, 13 | OUT2_B / OUT2_A | SIN analog outputs - each tied to separate die; used for differential or cross-check angle computation. |
| 8, 16 | OUT1_B / OUT1_A | COS analog outputs - paired with respective OUT2 pins to form complete sine/cosine channel pairs. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs per die - must be decoupled locally; unused VDD3V3 pins left floating in 5V mode. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs per die - used only when operating at 3.3V; VDD5V pins left floating in 3.3V mode. |
| 2, 3, 10, 11, 12 | NC / TEST_A / TEST_B | No-connect or test pins - require grounding per datasheet for optimal EMC behavior. |
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 both end-of-shaft (two-pole) and through-shaft (multi-pole) magnet arrangements. |
| Dual-Die Redundancy | Fully independent A/B die paths support ISO 26262 ASIL-B/C fault detection via cross-die comparison of angle outputs. |
| High-Speed Analog Outputs | 4 µs update period and 12 µs tracking delay enable real-time field-oriented control (FOC) at >25,000 rpm. |
| Factory-Set Sensitivity | 30 mT full-scale range optimized for NdFeB magnets ensures maximum signal-to-noise ratio and ADC resolution utilization. |

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-023-RE | Same package and magnetic axis, but 20mT full-scale range and medium bandwidth (29.5 µs tracking delay). | Better suited for lower-speed motors (<10,000 rpm) or systems prioritizing noise immunity over latency. | Select when angular bandwidth demand is lower and higher SNR at reduced field strength is required. |

FAQ
What magnetic axis configuration is implemented in MLX90380LGO-BAB-043-SP?
The MLX90380LGO-BAB-043-SP is factory-programmed for the X/Z intrinsic magnetic axis (per option code digit '0' in '043'), meaning OUT1 measures the Z-axis field component and OUT2 measures the X-axis field component. This configuration supports both end-of-shaft and through-shaft magnet arrangements and is validated for NdFeB magnets.
Does MLX90380LGO-BAB-043-SP support both 3.3V and 5V supply simultaneously?
No - MLX90380LGO-BAB-043-SP is configured for 3.3V high-bandwidth operation (per '043' coding: '0xx' = 3.3V + high BW). Only VDD3V3_A and VDD3V3_B should be powered; VDD5V_A and VDD5V_B must remain unconnected. Using 5V on those pins violates absolute maximum ratings.
What is the full-scale magnetic range of MLX90380LGO-BAB-043-SP and how is it set?
The MLX90380LGO-BAB-043-SP has a factory-programmed full-scale magnetic range of 30 mT (per 'x43' suffix: '043' → 30 mT). This setting optimizes output swing (±40% VDD) for NdFeB magnets and is fixed at production - not user-adjustable in the field.
How does the dual-die TSSOP-16 package enhance functional safety in MLX90380LGO-BAB-043-SP?
The MLX90380LGO-BAB-043-SP integrates two fully independent sensor dies (A and B) in one TSSOP-16 package, each with dedicated power, ground, and analog outputs. This enables hardware-level cross-checking of angle results - a key requirement for ISO 26262 ASIL-B/C compliance in automotive motor control systems.
Can MLX90380LGO-BAB-043-SP achieve ±1° angular accuracy in production systems?
Yes - MLX90380LGO-BAB-043-SP achieves ±1° total angular error *with dynamic compensation*, which requires external ECU-based offset, gain, and phase correction applied to the raw sine/cosine outputs before arctan calculation. This is distinct from the ±10°–15° error specified without correction.
