Product details
Overview
MLX90380LGO-BAB-123-SP from Melexis is a Triaxis® monolithic contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs for resolver replacement in motor control systems. 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.
For engineers reviewing the MLX90380LGO-BAB-123-SP datasheet, pinout, applications, or equivalent options, this device serves as a high-temperature, dual-die redundant angular position sensor optimized for field-oriented control of BLDC and PMSM motors where end-of-shaft or through-shaft mounting is required.
Technical Context
The MLX90380LGO-BAB-123-SP implements Triaxis® Hall technology with integrated signal conditioning to resolve orthogonal and parallel magnetic flux components on a single die. Its dual analog outputs (OUT1 = COS, OUT2 = SIN) are ratiometric to VDD and deliver ±40%VDD swing at full scale, enabling direct interface with standard ADC inputs without external scaling.
This TSSOP-16 variant contains two fully redundant dies (Die A and Die B), each with independent power supplies (VDD3V3_A/VDD5V_A and VDD3V3_B/VDD5V_B), ground pins (VSS_A/VSS_B), test pins (TEST_A/TEST_B), and dedicated sine/cosine outputs (OUT1_A/OUT2_A and OUT1_B/OUT2_B), supporting functional safety requirements per ISO 26262 ASIL-D architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angle tracking up to 25,000 rpm with <74 µs total tracking delay in high-bandwidth mode. |
| Operating Supply Voltage | 3.3 V or 5 V - Dual-rail support allows flexible MCU interface; VDD3V3 and VDD5V pins must be used separately per die. |
| Full-Scale Magnetic Range | 30 mT - Factory-programmed sensitivity matches NdFeB magnets in X/Z axis configuration for optimal SNR and linearity. |
| Operating Temperature Range | -40°C to +150°C - Qualified for under-hood automotive and industrial motor drive environments without derating. |
| Output Linearity Error | ±0.5% - Measured over 360° at VDD=5V within 0.5–4.5 V output range, enabling sub-degree angular resolution post-ADC. |
| Total Angular Error (uncorrected) | ±10° at 25°C, ±15° across full temperature range - Correctable via off-chip offset/gain/phase compensation in ECU firmware. |
| ESD Robustness | 1.5 kV HBM - Validated for TSSOP-16 cross-die layout per AEC-Q100-002, ensuring reliability in automated assembly and field operation. |
Pinout & Package
TSSOP-16 package with exposed thermal pad (non-electrical); 4.4 mm × 5.0 mm body, 0.65 mm pitch; designed for high-density PCB layouts and thermal management in motor control modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Independent ground returns for Die A and Die B - Must be connected to low-impedance system ground to maintain EMC and accuracy. |
| 4, 11 | TEST_A / TEST_B | Factory test access points - Connect to GND for optimal EMC; not intended for user programming or signal routing. |
| 5, 13 | OUT2_B / OUT2_A | Sine analog outputs for Die B and Die A - Ratiometric to respective VDD rail; require 1.5–10 nF load capacitance for stability. |
| 8, 16 | OUT1_B / OUT1_A | Cosine analog outputs for Die B and Die A - Paired with OUT2 to form orthogonal angle representation; enable arctan(OUT2/OUT1) computation. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs for Die B and Die A - Used when operating at 5V; VDD3V3 pins must remain 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 remain floating in this mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Fully independent signal chains (Die A + Die B) in one TSSOP-16 package support ASIL-D fault detection and diagnostic coverage. |
| Selectable magnetic axis (X/Z) | Enables compatibility with both end-of-shaft (X/Y) and through-shaft (X/Z or Z/Y) magnet configurations without hardware change. |
| Programmable sensitivity (30 mT) | Optimizes ADC input utilization for NdFeB magnets, reducing quantization error and improving effective angular resolution. |
| Ratiometric analog outputs | Eliminates need for precision voltage references; output swing scales directly with VDD, simplifying system-level calibration. |
| 4 µs output update period | Supports high-speed motor control loops with minimal latency - critical for field-oriented control at >10,000 rpm. |
Applications
| Brushless Motor Control | Electric Power Steering (EPS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless angular position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LGO-BAB-125-RE | Same package and magnetic axis, but programmed for 60 mT full-scale range using NdFeB magnet - higher sensitivity, lower SNR margin. | Better suited for low-field magnet geometries or longer air gaps; requires ADC input range reconfiguration. | Select when magnet flux density at sensor location is <25 mT peak-to-peak and system prioritizes dynamic range over noise floor. |
| MLX90380LDC-BAB-123-RE | SOIC-8 single-die version with identical option code (BAB-123), same 30 mT range and X/Z axis - no redundancy, smaller footprint. | Targeted at cost-sensitive, non-safety-critical applications like consumer appliances or basic industrial fans. | Choose for space-constrained designs where ASIL-D compliance is not required and BOM cost reduction is primary. |
Compared with MLX90380LGO-BAB-123-SP, the -125-RE offers extended magnetic range at the expense of noise performance, while the SOIC-8 -123-RE reduces size and cost but eliminates functional safety capability - selection depends strictly on magnet geometry, safety architecture, and thermal constraints.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-123-SP?
The MLX90380LGO-BAB-123-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 and enables compatibility with multi-pole off-axis magnets where Z/Y or X/Z orientation is required.
Does MLX90380LGO-BAB-123-SP support both 3.3V and 5V operation simultaneously?
No - MLX90380LGO-BAB-123-SP does not support simultaneous 3.3V and 5V operation. Each die (A and B) must be powered from either VDD3V3 or VDD5V, with the unused rail left floating. The option code BAB-123 specifies high-bandwidth mode, which is compatible with either supply voltage but requires correct rail selection per application diagram.
How is redundancy implemented in MLX90380LGO-BAB-123-SP?
MLX90380LGO-BAB-123-SP integrates two fully independent sensor dies (Die A and Die B) in a single TSSOP-16 package, each with separate power supplies, grounds, test pins, and analog outputs. This physical separation enables cross-die comparison, fault detection, and fail-safe response required for ASIL-D systems without external duplication.
What is the full-scale magnetic range of MLX90380LGO-BAB-123-SP and how is it set?
The MLX90380LGO-BAB-123-SP has a factory-programmed full-scale magnetic range of 30 mT, corresponding to the "xx3" digit in its option code. This sensitivity is calibrated for NdFeB magnets and ensures ±40%VDD output swing at full scale, optimizing ADC utilization without external gain stages.
Can MLX90380LGO-BAB-123-SP be used with ferrite or SmCo magnets?
No - MLX90380LGO-BAB-123-SP is specifically programmed for NdFeB magnets, as indicated by the "BAB" prefix in its option code. Using ferrite (BAC) or SmCo (BAA) magnets would result in incorrect sensitivity scaling and degraded angular accuracy; alternate variants must be selected for those magnet types.
