Product details
Overview
MLX90380LGO-BAB-123-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 4 µs output refresh rate, and is factory-programmed for NdFeB magnet compatibility, X/Z magnetic axis configuration, 30 mT full-scale range, and high-bandwidth operation.
For engineers reviewing the MLX90380LGO-BAB-123-RE datasheet, pinout, applications, or equivalent options, this device serves as a high-accuracy, automotive-grade absolute rotary position sensor in brushless motor control, field-oriented control, and end-of-shaft or through-shaft configurations where thermal robustness and magnetic axis flexibility are critical.
Technical Context
The MLX90380LGO-BAB-123-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components, enabling precise arctangent-based angle computation. Its dual-die TSSOP-16 architecture provides full redundancy with independent COS/SIN outputs per die (OUT1_A/OUT2_A and OUT1_B/OUT2_B), supporting functional safety requirements.
Programmable sensitivity (30 mT range), selectable bandwidth (high BW mode), and X/Z axis orientation are factory-set per the BAB-123 option code. Output tracking delay is 12 µs in high-bandwidth mode, and ratiometric outputs maintain linearity better than 0.5% over VDD=4.5–5.5V at TA=25°C.
Key Specifications

|---|---|
Use Scenario: Precise rotor position feedback in permanent magnet synchronous motors (PMSM) and BLDC motors used in electric power steering and traction inverters. IC Role / Device Role / Timing Role: Absolute 360° angular encoder providing real-time sine/cosine signals for commutation timing and torque vector calculation. Use Value: Enables smooth low-speed torque delivery and high-efficiency field weakening above base speed due to ±1° compensated angular accuracy. |
Use Scenario: High-dynamic servo drives requiring continuous d-q axis transformation in industrial automation and robotics. IC Role / Device Role / Timing Role: Resolver substitute delivering synchronized COS/SIN outputs to MCU ADCs for real-time Park/Clarke transforms. Use Value: 4 µs update rate and 12 µs tracking delay ensure minimal current loop latency, improving torque ripple suppression and bandwidth. |
| End-of-Shaft Position Sensing | Through-Shaft Position Sensing |
Use Scenario: Compact rotary position feedback on motor shaft ends where axial space is constrained, e.g., HVAC blower actuators and throttle valves. IC Role / Device Role / Timing Role: Contactless angular transducer mounted directly on shaft endcap, sensing radial field from diametrically magnetized rotor. Use Value: X/Z axis configuration allows accurate measurement with minimal air gap; -40°C to 150°C rating ensures reliability in sealed, thermally isolated housings. |
Use Scenario: Position sensing across hollow motor shafts in gearmotor assemblies and electric powertrain differentials. IC Role / Device Role / Timing Role: Through-shaft resolver alternative using axial field coupling from ring magnet mounted inside shaft bore. Use Value: Programmable X/Z axis and 30 mT range optimize signal-to-noise ratio for low-profile ring magnets, reducing mechanical alignment sensitivity. |
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-103-RE | Same TSSOP-16 package and NdFeB magnet support, but configured for X/Z axis, 10 mT range, and low-bandwidth mode | Lower magnetic sensitivity and slower 74 µs tracking delay - suited for lower-speed, cost-sensitive applications | Select when magnet strength is limited and motor speed ≤ 5,000 rpm; not suitable for high-BW FOC |
| MLX90380LGO-BAB-143-RE | Identical package and magnet type, but programmed for Z/Y axis, 30 mT range, and high-bandwidth mode | Z/Y axis orientation requires different magnet mounting geometry (axial vs. radial field coupling) | Choose for through-shaft designs using axial-field ring magnets; verify mechanical layout compatibility before substitution |
Compared with MLX90380LGO-BAB-103-RE and MLX90380LGO-BAB-143-RE, the MLX90380LGO-BAB-123-RE uniquely combines NdFeB-optimized 30 mT sensitivity, X/Z axis orientation, and high-bandwidth response-making it the preferred choice for high-speed, thermally demanding end-of-shaft PMSM control where minimal latency and robust field coupling are essential.

FAQ
What magnetic axis configuration is implemented in the MLX90380LGO-BAB-123-RE?
The MLX90380LGO-BAB-123-RE is factory-programmed for the X/Z magnetic axis configuration, meaning OUT1 corresponds to the X-axis magnetic component and OUT2 to the Z-axis component. This orientation supports both end-of-shaft and through-shaft applications using appropriate magnet geometries, and is explicitly defined by the "BAB-123" option code per Melexis' ordering guide.
Does the MLX90380LGO-BAB-123-RE support both 3.3V and 5V supply voltages simultaneously?
No - the MLX90380LGO-BAB-123-RE is configured for 5V operation only, as indicated by the "123" suffix (where "1" denotes 5V supply voltage and high bandwidth). When powered from 5V, VDD3V3 pins must remain floating; connecting both supplies risks damage or undefined behavior. The device draws 9–10 mA typical supply current under 5V conditions.
What is the full-scale magnetic range of the MLX90380LGO-BAB-123-RE and which magnet type does it target?
The MLX90380LGO-BAB-123-RE has a factory-programmed full-scale magnetic range of 30 mT and is optimized for use with NdFeB (Neodymium Iron Boron) permanent magnets, as specified by the "BAB" prefix in its option code. This range delivers optimal signal-to-noise ratio and linearity when paired with standard-grade NdFeB rotors in motor feedback applications.
How does the dual-die TSSOP-16 architecture of the MLX90380LGO-BAB-123-RE enhance functional safety?
The MLX90380LGO-BAB-123-RE integrates two fully independent sensor dies in one TSSOP-16 package, each generating its own COS/SIN output pair (OUT1_A/OUT2_A and OUT1_B/OUT2_B). This redundancy enables cross-die consistency checking, fault detection, and fail-safe angle computation - supporting ASIL-B/C compliance in automotive motor control per ISO 26262 without requiring external duplication.
Can the MLX90380LGO-BAB-123-RE be reprogrammed after shipment?
No - the MLX90380LGO-BAB-123-RE is factory-programmed with fixed parameters including magnetic axis (X/Z), sensitivity range (30 mT), magnet type (NdFeB), supply voltage (5V), and bandwidth (high). Programming is performed during final test using dedicated equipment; no field reprogramming capability exists via the TEST pins or analog outputs. Configuration is immutable post-manufacture.
