Product details
Overview
MLX90380LGO-BAA-100-TU 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, achieves 4 µs output refresh rate, and is configured for X/Y magnetic axis with SmCo magnet compatibility and 40 mT full-scale range.
For engineers reviewing the MLX90380LGO-BAA-100-TU datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TSSOP-16 package details, magnetic axis configuration, ratiometric output behavior, and validated alternative options for motor control and industrial positioning systems.
Technical Context
The MLX90380LGO-BAA-100-TU implements dual-die redundancy in a single TSSOP-16 package, with independent Die A and Die B each providing COS (OUT1) and SIN (OUT2) analog outputs referenced to their respective VDD and VSS pins. Its Triaxis® Hall architecture measures orthogonal and parallel magnetic flux components simultaneously, enabling contactless angular position resolution without gears or brushes.
This variant uses BAA-100 option coding: X/Y magnetic axis, SmCo magnet compatibility, 40 mT full-scale range, 3.3V supply voltage, and high-bandwidth programming mode - yielding 125 kHz Nyquist frequency and 12 µs tracking delay. Output ratiometry ensures immunity to supply variation, while factory-programmed sensitivity and offset calibration support end-of-line accuracy enhancement.

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 |
|---|---|---|---|
| MLX90380LDC-BAA-100-RE | SOIC-8 single-die variant; identical BAA-100 option coding, same 3.3V/40 mT/X/Y spec but no redundancy | Used where functional safety requirements are lower (e.g., non-automotive industrial drives) | Select when cost and board space are prioritized over dual-die fault tolerance |
| MLX90393ELQ-ABA-000-SP | Triaxis® 3D Hall sensor with I²C digital output; ±50 g 3-axis field measurement, not resolver-mode sine/cosine generation | Applied in tilt/orientation sensing, not motor commutation; lacks analog resolver outputs and high-speed update | Choose only for 3D magnetic vector measurement-not as a drop-in replacement for resolver functionality |
Compared with MLX90380LGO-BAA-100-TU, the SOIC-8 MLX90380LDC-BAA-100-RE offers identical magnetic performance in a smaller footprint but no redundancy, while MLX90393ELQ-ABA-000-SP serves fundamentally different use cases with digital 3D field data instead of analog resolver outputs.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAA-100-TU?
The MLX90380LGO-BAA-100-TU is factory-programmed for X/Y magnetic axis configuration, meaning OUT1 responds proportionally to the BX field component and OUT2 to BY. This supports end-of-shaft mounting with two-pole magnets and enables true 360° angular measurement without ambiguity. The BAA-100 option code explicitly defines this X/Y orientation, confirmed in Table 2 of the datasheet.
Does MLX90380LGO-BAA-100-TU support both 3.3V and 5V supply voltages simultaneously?
No, MLX90380LGO-BAA-100-TU operates exclusively in 3.3V mode as indicated by its BAA-100 option code ('0xx' suffix = 3.3V low-bandwidth, but this variant uses high-bandwidth mode per revision notes). VDD5V pins (6 and 14) must remain floating; only VDD3V3 pins (7 and 15) are powered. Simultaneous 3.3V/5V operation is not supported and violates absolute maximum ratings.
How does the dual-die redundancy in MLX90380LGO-BAA-100-TU improve system reliability?
The MLX90380LGO-BAA-100-TU integrates two fully independent signal chains (Die A and Die B) in one TSSOP-16 package, each with separate VDD/VSS, OUT1/OUT2, and TEST pins. This allows cross-checking of outputs for fault detection, supporting ASIL-B/C compliance in automotive EPS and traction inverters. Redundancy mitigates single-point failures without doubling PCB area or connector count.
What is the full-scale magnetic range and magnet type compatibility for MLX90380LGO-BAA-100-TU?
The MLX90380LGO-BAA-100-TU has a 40 mT full-scale magnetic range and is optimized for Samarium-Cobalt (SmCo) magnets, as specified by the 'BAA' prefix in its option code. This configuration yields ±40% VDD output swing at 25°C and supports stable operation across -40°C to 150°C, making it suitable for high-temperature motor applications where SmCo's thermal stability is critical.
Can MLX90380LGO-BAA-100-TU be used with a through-shaft magnet configuration?
No - MLX90380LGO-BAA-100-TU's X/Y magnetic axis configuration is intended for end-of-shaft or on-axis two-pole magnet use, not through-shaft. Through-shaft operation requires Z/Y or X/Z axis variants (e.g., BAB or BAC option codes with 'x2x' or 'x1x' suffixes). Using this part with a through-shaft magnet will result in degraded linearity and angular error exceeding specification limits.
