Product details
Overview
MLX90380LGO-BAB-023-SP from Melexis is a Triaxis® monolithic contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs with 4 µs output refresh rate, ±40%VDD swing, and ratiometric operation across 3.3 V or 5 V supply. It supports end-of-shaft and through-shaft configurations using NdFeB magnets and operates from −40°C to 150°C in automotive and industrial motor control systems.
For engineers reviewing the MLX90380LGO-BAB-023-SP datasheet, pinout, applications, or equivalent options, this TSSOP-16 dual-die redundant resolver provides high-speed angular sensing with programmable magnetic axis (X/Z), 30 mT full-scale range, and dynamic compensation-ready analog outputs for BLDC and PMSM field-oriented control.
Technical Context
The MLX90380LGO-BAB-023-SP implements Triaxis® Hall technology with orthogonal and parallel magnetic field sensitivity, enabling precise angular resolution via dual analog outputs (OUT1 = COS, OUT2 = SIN). Its X/Z magnetic axis configuration supports off-axis through-shaft magnet placement with equal sensitivity on X and Z axes.
This variant uses NdFeB magnets (BAB prefix), offers 30 mT full-scale magnetic range (xx3 suffix), and operates at high bandwidth (BAx-023 → 3.3 V supply + high BW). The dual-die TSSOP-16 package delivers functional redundancy with independent power and ground pins per die (VSS_A/VDD3V3_A/VDD5V_A/OUT1_A/OUT2_A and VSS_B/VDD3V3_B/VDD5V_B/OUT1_B/OUT2_B).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angular tracking up to 25,000 rpm with ≤12 µs total tracking delay in high-bandwidth mode. |
| Full-Scale Magnetic Range | 30 mT - Factory-programmed for NdFeB magnets; defines ±40%VDD output swing at TA = 25°C. |
| Magnetic Axis Configuration | X/Z - Supports through-shaft applications with equal sensitivity on X and Z axes; enables robust off-axis positioning. |
| Supply Voltage Options | 3.3 V or 5 V - Dual supply pins (VDD3V3_A/B and VDD5V_A/B); only one supply active per die; VDD3V3 must float in 5 V mode. |
| Operating Temperature | −40°C to 150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Output Type | Ratiometric sine/cosine analog - Outputs scale linearly with VDD; enables direct ADC interfacing without external reference. |
| Total Angular Error | ±1° with dynamic compensation - Achievable via external ECU offset/gain/phase correction prior to arctan(OUT2/OUT1) computation. |
Pinout & Package
TSSOP-16 package with dual-die fully redundant architecture. Each die has independent power, ground, test, and analog output terminals to support safety-critical applications requiring ASIL-D 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-isolation diagnostics. |
| 4, 11 | TEST_A / TEST_B | Factory test access points - Must be tied to GND for optimal EMC; not user-accessible in normal operation. |
| 5, 13 | OUT2_B / OUT2_A | Sine analog outputs for Die B and Die A - Ratiometric, ±40%VDD swing, 4 µs update period per channel. |
| 8, 16 | OUT1_B / OUT1_A | Cosine analog outputs for Die B and Die A - Paired with respective OUT2 for arctan-based angle calculation. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs - Active when 5 V operation selected; VDD3V3 pins must remain floating in this mode. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs - Active when 3.3 V operation selected; VDD5V pins must remain floating in this mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die TSSOP-16 redundancy | Independent signal chains per die enable cross-checking and fail-safe angular reporting for ISO 26262 ASIL-D systems. |
| Programmable X/Z magnetic axis | Optimizes sensitivity alignment for through-shaft permanent magnet placement without mechanical reorientation. |
| 30 mT full-scale range (NdFeB) | Matches common NdFeB magnet strengths in BLDC/PMSM rotors; minimizes ADC quantization error at system level. |
| High-bandwidth 4 µs update | Supports closed-loop FOC at >20 kHz current loop rates; reduces phase lag in high-dynamic motor applications. |
| Ratiometric analog outputs | Eliminates need for precision voltage reference; maintains accuracy across VDD tolerance and temperature drift. |
Applications

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-025-RE | Same TSSOP-16 dual-die package, NdFeB magnet, X/Z axis, but 60 mT full-scale range (xx5) vs. 30 mT (xx3). | Better suited for higher-flux magnet assemblies or low-sensitivity mechanical tolerances; requires ADC input scaling adjustment. | Select when magnet air gap varies widely or when higher noise immunity is needed at the cost of reduced angular resolution. |
| MLX90380LDC-BAB-023-RE | SOIC-8 single-die version with identical option code (BAB-023), same 30 mT range and X/Z axis, but no redundancy. | Lacks dual-die fault detection capability; suitable for non-safety-critical cost-sensitive applications. | Choose for space-constrained PCBs where ASIL-B/C suffices and redundancy is not mandated by system architecture. |
Compared with MLX90380LGO-BAB-023-SP, the -025-RE offers extended magnetic range for less sensitive mechanical setups, while the SOIC-8 -023-RE reduces cost and footprint at the expense of functional safety compliance-making the TSSOP-16 dual-die variant essential for ASIL-D motor control.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-023-SP?
The MLX90380LGO-BAB-023-SP is factory-programmed for X/Z magnetic axis configuration, supporting through-shaft applications with equal sensitivity on both axes. This allows accurate angular measurement when the magnet is placed axially relative to the IC surface, as confirmed in Table 2 and Section 8.2 of the datasheet.
Does MLX90380LGO-BAB-023-SP support both 3.3 V and 5 V supply voltages simultaneously?
No-MLX90380LGO-BAB-023-SP supports either 3.3 V or 5 V operation, not both simultaneously. The part uses separate VDD3V3_A/B and VDD5V_A/B pins; only one supply rail per die must be active, and the unused supply pin must be left floating per Section 9.2 and Application Diagrams 13.1.1–13.2.2.
What is the full-scale magnetic range programmed into MLX90380LGO-BAB-023-SP?
The "023" option code specifies a 30 mT full-scale magnetic range for NdFeB magnets. This is defined in Table 2: BAx-xx3 corresponds to 30 mT, producing ±40%VDD output swing at TA = 25°C with VDD = nominal supply, per Section 12 specifications.
How does the dual-die redundancy in MLX90380LGO-BAB-023-SP improve functional safety?
The TSSOP-16 package contains two independent sensor dies (A and B), each with dedicated power, ground, and analog outputs. This enables cross-die comparison for fault detection, supporting ISO 26262 ASIL-D requirements-unlike single-die variants such as MLX90380LDC-BAB-023-RE.
Can MLX90380LGO-BAB-023-SP be used with ferrite or SmCo magnets?
No-MLX90380LGO-BAB-023-SP is specifically calibrated for NdFeB magnets, as indicated by the "BAB" prefix in its ordering code. Using ferrite (BAC) or SmCo (BAA) magnets would cause significant sensitivity mismatch and angular error, since TCS and offset drift characteristics are magnet-type-specific per Section 12.1 and Table 2.
