Product details
Overview
MLX90380LGO-BAB-143-RE 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 with sensitivity mismatch, 30mT full-scale range, and high-bandwidth operation. It enables precise rotor angle feedback in brushless motor control systems.
For engineers reviewing the MLX90380LGO-BAB-143-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, TSSOP-16 package mapping, magnetic axis configuration details, real-world angular error performance, and validated alternative options for automotive and industrial motor control designs.
Technical Context
The MLX90380LGO-BAB-143-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two independent die in a TSSOP-16 package. Its dual-die architecture provides functional redundancy, with separate VDD3V3_A/VDD5V_A and VDD3V3_B/VDD5V_B supplies and isolated ground pins (VSS_A/VSS_B).
This variant is configured for X/Z magnetic axis with sensitivity mismatch-meaning the Z-axis sensitivity is half that of the X-axis-optimized for off-axis through-shaft applications with two-pole magnets. Output tracking delay is 12 µs under high-bandwidth programming, and angular accuracy achieves ±1° total error with dynamic compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Type | Dual ratiometric analog: OUT1 = COS, OUT2 = SIN, both referenced to VDD |
| Output Refresh Rate | 4 µs per field component (8 µs full sine/cosine pair), enabling >25,000 rpm operation |
| Supply Voltage | 3.3V or 5V operation; VDD3V3 and VDD5V pins are separate per die, not shared |
| Full-Scale Magnetic Range | 30 mT (factory-programmed BAB-143 option code), supporting NdFeB magnets |
| Operating Temperature | -40°C to +150°C ambient, qualified for automotive powertrain and industrial motor environments |
| Angular Accuracy | ±1° total error with dynamic compensation; ±10° uncorrected at 25°C |
| Magnetic Axis | X/Z configuration with sensitivity mismatch (Bz sensitivity = 50% of Bx), for through-shaft use |
Pinout & Package
TSSOP-16 package with dual-die redundancy: two independent sensor dies (A and B), each with dedicated power, ground, test, and analog output pins. Pin 1 is VSS_A; pin 9 is VSS_B; pins 2/3/10/12 are NC; pins 4/11 are TEST_A/TEST_B; pins 5/8/13/16 carry analog outputs (OUT2_B, OUT1_B, OUT2_A, OUT1_A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns for Die A and Die B-must be connected to system ground independently |
| 4, 11 | TEST_A / TEST_B | Factory test access; connect to GND for optimal EMC in production |
| 5, 8, 13, 16 | OUT2_B, OUT1_B, OUT2_A, OUT1_A | Dual-die sine/cosine outputs: OUT1 = COS, OUT2 = SIN per die; ratiometric to respective VDD |
| 6, 7, 14, 15 | VDD5V_B, VDD3V3_B, VDD5V_A, VDD3V3_A | Independent 5V/3.3V supply inputs per die-no cross-die sharing; float unused VDD rail |
Key Features
| Feature | Design Value |
|---|---|
| Dual-die redundancy | Fully independent A/B sensor dies in one TSSOP-16 package-supports ASIL-D functional safety architectures |

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-043-RE | Same TSSOP-16 package and dual-die architecture, but programmed for 50mT full-scale range and medium bandwidth (29.5 µs tracking delay) | Better suited for lower-speed, higher-flux applications where extended magnetic range outweighs latency requirements | Select when magnet air gap is large or flux density exceeds 30mT; verify ADC input range compatibility with 50mT sensitivity |
| MLX90380LDC-BAB-143-RE | Identical magnetic configuration (BAB-143) but in SOIC-8 single-die package-no redundancy, smaller footprint, lower cost | Applicable where functional safety requirements do not mandate dual-die redundancy (e.g., non-automotive industrial) | Choose for cost-sensitive, space-constrained designs without ASIL-D requirements; shares same programming and signal chain |
Compared with MLX90380LGO-BAB-043-RE, the -143 variant trades magnetic range for lower latency-critical for high-RPM motors. Against MLX90380LDC-BAB-143-RE, it adds die-level redundancy at the cost of board area and BOM count, directly addressing ISO 26262 hardware fault tolerance needs.

FAQ
What magnetic axis configuration does MLX90380LGO-BAB-143-RE implement?
The MLX90380LGO-BAB-143-RE implements an X/Z magnetic axis with sensitivity mismatch-where Z-axis sensitivity is 50% of X-axis sensitivity-as defined by the BAB-143 option code. This configuration is optimized for two-pole magnet through-shaft applications and requires no external gain adjustment for standard use cases. The device outputs COS on OUT1 and SIN on OUT2 per die.
How does the dual-die architecture of MLX90380LGO-BAB-143-RE support functional safety?
The MLX90380LGO-BAB-143-RE integrates two fully independent sensor dies (Die A and Die B) in one TSSOP-16 package, each with separate power, ground, and analog output pins. This physical and electrical isolation enables comparison-based fault detection per ISO 26262, supporting ASIL-D decomposition. No shared supply or ground paths exist between dies, eliminating single-point failure modes in safety-critical motor control.
What is the output update timing behavior of MLX90380LGO-BAB-143-RE under high-bandwidth programming?
Under high-bandwidth programming (BAB-143's default setting), the MLX90380LGO-BAB-143-RE delivers a 4 µs output refresh rate per field component-meaning OUT1 and OUT2 update sequentially every 4 µs, resulting in a full sine/cosine pair every 8 µs. Tracking delay is 12 µs, enabling accurate angle capture at rotational speeds up to 25,000 rpm without interpolation artifacts.
Can MLX90380LGO-BAB-143-RE operate from both 3.3V and 5V supplies simultaneously?
No-MLX90380LGO-BAB-143-RE must be powered from either 3.3V or 5V per die, not both simultaneously. Each die has dedicated VDD3V3_X and VDD5V_X pins; the unused supply rail must be left floating (not grounded). For example, if powering Die A from 5V, VDD3V3_A must float, while VDD5V_A is connected to 5V. This prevents internal latch-up and ensures specification compliance.
What is the angular accuracy specification of MLX90380LGO-BAB-143-RE with and without compensation?
The MLX90380LGO-BAB-143-RE achieves ±10° total angular error without correction at -40°C to +150°C, and ±1° with dynamic compensation applied in the host ECU (e.g., offset/gain/phase correction prior to arctan computation). This compensated accuracy meets ISO 26262 torque-loop requirements for automotive EPS and traction inverters, assuming proper mechanical integration and magnet alignment.
