Product details
Overview
MLX90380LGO-BAB-100-RE from Melexis is a monolithic Triaxis® resolver IC delivering true 360° contactless angular position sensing via dual ratiometric sine/cosine analog outputs, with 4 µs output refresh rate, -40°C to 150°C operating range, and factory-programmed NdFeB magnet sensitivity for X/Z magnetic axis configuration in TSSOP-16 package. It serves as the primary rotor angle transducer in high-reliability brushless motor control systems.
For engineers reviewing the MLX90380LGO-BAB-100-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions for dual-die TSSOP-16, magnetic axis–specific performance data, and validated alternatives for automotive-grade motor position feedback design.
Technical Context
The MLX90380LGO-BAB-100-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two integrated die in fully redundant TSSOP-16 packaging. Its dual analog outputs (OUT1_A/OUT1_B as COS, OUT2_A/OUT2_B as SIN) are ratiometric to VDD and support programmable bandwidth-here configured for high-bandwidth operation (BAB-100 suffix indicates 3.3V supply + high BW).
This variant uses NdFeB magnet calibration (BAB prefix), X/Z intrinsic magnetic axis (third digit '1' in BAB-100), and 40 mT full-scale magnetic range (first digit '0'). Output tracking delay is 12 µs, and total angular error with dynamic compensation is ±1° across -40°C to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time rotor position capture at up to 25,000 rpm without interpolation latency. |
| Operating Temperature Range | -40°C to 150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Magnetic Axis Configuration | X/Z - Supports off-axis through-shaft magnet mounting with equal sensitivity on X and Z axes. |
| Supply Voltage | 3.135 V to 3.6 V - High-bandwidth mode requires stable 3.3 V rail; VDD3V3_A/B must be powered, VDD5V_A/B left floating. |
| Full-Scale Magnetic Range | 40 mT - Factory-programmed for NdFeB magnets; delivers ±40% VDD output swing at TA = 25°C. |
| Total Angular Error (Dynamic) | ±1° - Achievable with external ECU-based offset/gain/phase correction applied pre-arctan(OUT2/OUT1). |
| Tracking Delay | 12 µs - Time from magnetic stimulus change to synchronized SIN/COS update under high-BW programming. |
Pinout & Package
TSSOP-16 package with dual-die redundancy: Die A (pins 1,4,13–16) and Die B (pins 5–9) provide independent COS/SIN outputs for functional safety compliance. All NC pins and TEST pins must be connected to ground for optimal EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Dedicated ground returns per die-mandatory separation prevents cross-die noise coupling. |
| 5, 13 | OUT2_B / OUT2_A | SIN outputs for Die B and Die A-ratiometric to respective VDD rails; require matched ADC input scaling. |
| 8, 16 | OUT1_B / OUT1_A | COS outputs for Die B and Die A-paired with corresponding OUT2 pins to form redundant resolver quadrature pairs. |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs-must remain floating when operating in 3.3 V high-BW mode (BAB-100). |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3 V supply inputs-both must be actively driven; power sequencing must meet VPOR_H ≥ 2.75 V. |
| 2, 3, 10, 11, 12 | NC / TEST_A / TEST_B | No-connect and test terminals-grounding required per datasheet to suppress EMI and enable EEPROM diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Z) field measurement eliminates need for external flux concentrators or multi-sensor assemblies. |
| Programmable Bandwidth | High-BW mode (BAB-100) enables 12 µs tracking delay-critical for field-oriented control (FOC) loop closure at >10 kHz. |
| Dual-Die Redundancy | Independent COS/SIN outputs per die support ASIL-D–compliant diagnostics and fault-tolerant angle reconstruction. |
| Ratiometric Outputs | Output voltage scales linearly with VDD-removes supply variation impact on angle calculation accuracy in noisy power domains. |
| End-of-Shaft / Through-Shaft Flexibility | X/Z axis configuration supports both on-axis (end-of-shaft) and off-axis (through-shaft) magnet placements without hardware redesign. |
Applications
| Brushless Motor Rotor Position Feedback | Electric Power Steering (EPS) Angle Sensing |

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-BAA-100-RE | Uses SmCo magnet calibration instead of NdFeB; identical X/Z axis, 40 mT range, and high-BW mode. | Better high-temperature stability above 120°C but higher cost; less common in cost-sensitive EV traction systems. | Select when magnet operating temperature exceeds 120°C or long-term flux stability is prioritized over cost. |
| MLX90380LGO-BAC-100-RE | Uses Ferrite magnet calibration; same X/Z axis and high-BW mode, but lower sensitivity (0.57%VDD/mT vs. 1.33%VDD/mT for NdFeB). | Requires stronger magnetic field or larger magnet volume; suited for low-cost industrial actuators where size is not constrained. | Select for cost-driven applications with available magnetic budget and relaxed size constraints. |
Compared with MLX90380LGO-BAB-100-RE, the BAA-100 offers superior thermal drift performance for extreme ambient conditions, while the BAC-100 trades sensitivity for material cost reduction-neither is pin-compatible with SOIC-8 variants, and all TSSOP-16 options require identical PCB layout and dual-die signal routing.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-100-RE?
The MLX90380LGO-BAB-100-RE is factory-programmed for X/Z magnetic axis configuration, meaning OUT1 measures the X-component and OUT2 measures the Z-component of the applied magnetic field. This supports through-shaft off-axis mounting and is confirmed by the 'BAB' option code's third digit '1' per Melexis ordering guide.
Does MLX90380LGO-BAB-100-RE support both 3.3 V and 5 V supply rails simultaneously?
No-MLX90380LGO-BAB-100-RE operates exclusively from 3.3 V (VDD3V3_A/B) in high-bandwidth mode. The VDD5V_A/B pins must remain unconnected (floating) per datasheet Section 9.2 and Application Diagram VDD3V3. Applying 5 V to those pins risks violating absolute maximum ratings.
How is redundancy implemented in MLX90380LGO-BAB-100-RE?
MLX90380LGO-BAB-100-RE integrates two independent die in one TSSOP-16 package: Die A (pins 13–16) and Die B (pins 5–9) each generate full COS/SIN output pairs. This dual-die architecture enables cross-die comparison, fault detection, and ASIL-D–compliant angle reconstruction without external components.
What is the full-scale magnetic range of MLX90380LGO-BAB-100-RE and how is it set?
The MLX90380LGO-BAB-100-RE has a 40 mT full-scale magnetic range, factory-programmed via its 'BAB-100' option code (first digit '0'). This defines the in-plane flux density yielding ±40% VDD output swing at 25°C, optimized for NdFeB magnets and used directly in arctan(OUT2/OUT1) computation.
Can MLX90380LGO-BAB-100-RE be used in end-of-shaft configurations?
Yes-although optimized for through-shaft (off-axis) use via its X/Z axis, MLX90380LGO-BAB-100-RE supports end-of-shaft mounting when paired with a two-pole magnet aligned to the X/Z plane. Figure 5 and Section 8.2 of the datasheet confirm CW/CCW rotation behavior compatibility for both configurations.
