Product details
Overview
MLX90380LGO-BAB-405-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 temperature, and programmable NdFeB magnet sensitivity (40 mT full-scale range), used in high-reliability motor control systems.
For engineers reviewing the MLX90380LGO-BAB-405-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, TSSOP-16 pin mapping, magnetic axis configuration (X/Z), bandwidth selection (high BW), and real-world motor control integration requirements.
Technical Context
The MLX90380LGO-BAB-405-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Z) magnetic field components using two integrated die in a fully redundant TSSOP-16 package. Its dual-die architecture enables functional safety compliance in ASIL-B/C automotive systems.
It delivers synchronized analog outputs (OUT1_A/OUT1_B as COS, OUT2_A/OUT2_B as SIN) with ratiometric scaling to VDD, programmable via four application pins for sensitivity (40 mT), magnetic axis (X/Z), supply voltage (3.3V or 5V), and filter bandwidth (high BW mode). Output update period is fixed at 4 µs per field component.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angle computation at up to 25,000 rpm with ≤12 µs tracking delay in high-bandwidth mode. |
| Operating Temperature | -40°C to 150°C - Qualified for under-hood automotive and industrial motor drive environments. |
| Supply Voltage | 3.135–3.6 V or 4.5–5.5 V - Dual-rail support allows flexible MCU interface without level-shifting. |
| Full-Scale Magnetic Range | 40 mT - Factory-programmed for NdFeB magnets; matches typical end-of-shaft rotor field strength. |
| Magnetic Axis | X/Z - Supports through-shaft configurations with equal sensitivity on X and Z axes per option code BAB. |
| Angular Accuracy | ±1° total error with dynamic compensation - Achievable via external ECU offset/gain correction of sine/cosine outputs. |
| Output Type | Ratiometric sine/cosine analog - Output voltages scale linearly with VDD (5–95% VDD range), simplifying ADC reference coupling. |
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 fault-tolerant angle decoding. All NC pins must be grounded for optimal EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Dedicated ground terminals per die - Enable independent ground return paths to minimize crosstalk. |
| 5, 13 | OUT2_B / OUT2_A | SIN analog outputs - Provide redundant sine signals for comparison or voting in safety-critical applications. |
| 8, 16 | OUT1_B / OUT1_A | COS analog outputs - Paired with respective SIN outputs to form two independent resolver channels. |
| 6, 14 | VDD5V_B / VDD5V_A | 5V supply inputs - Used when operating at 5V; VDD3V3 pins must remain floating in this configuration. |
| 7, 15 | VDD3V3_B / VDD3V3_A | 3.3V supply inputs - Used when operating at 3.3V; VDD5V pins must remain floating in this configuration. |
| 2, 3, 10, 11, 12 | NC / TEST_B / TEST_A | Not-connected and test pins - Must be connected to ground per datasheet for EMC integrity and noise immunity. |
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 Magnetic Axis | X/Z configuration supports through-shaft rotor mounting with mechanical simplicity and reduced air-gap sensitivity. |
| Dual-Die Redundancy | Fully independent signal chains (Die A + Die B) enable ASIL-B/C-compliant diagnostics and fault detection. |
| Ratiometric Analog Outputs | Outputs scale with VDD, eliminating dependency on stable reference voltage and easing integration with MCU ADCs. |
| High-Bandwidth Mode | 4 µs update period and 125 kHz Nyquist frequency support fast-response field-oriented control (FOC) loops. |
Applications
| Brushless Motor Control | Field-Oriented Control (FOC) |

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-405-RE | Uses SmCo magnet instead of NdFeB; higher TCS (350 ppm/°C vs. 1100 ppm/°C) and lower sensitivity drift. | Better suited for high-temperature-stable magnetic systems where SmCo magnets are specified. | Select when magnet type and thermal coefficient alignment with SmCo are required; not drop-in compatible due to different magnetic calibration. |
| MLX90380LGO-BAC-405-RE | Optimized for ferrite magnets; 2000 ppm/°C TCS and wider 40 mT range tolerance. | Targets cost-sensitive industrial applications using low-cost ferrite rotors with larger thermal drift budgets. | Choose for ferrite-based designs where extended temperature compensation is handled externally; requires revalidation of magnetic coupling. |
Compared with MLX90380LGO-BAB-405-RE, the BAA variant offers tighter thermal stability for SmCo systems, while the BAC variant trades precision for cost and flexibility with ferrite magnets-both require magnet-specific calibration and are not pin-to-pin functionally interchangeable without system-level requalification.

FAQ
What is the magnetic axis configuration of MLX90380LGO-BAB-405-RE?
The MLX90380LGO-BAB-405-RE is factory-programmed for X/Z magnetic axis configuration with equal sensitivity, supporting through-shaft rotor mounting where the magnetic field is applied orthogonally (Z) and parallel (X) to the IC surface. This is confirmed by the 'BAB' option code and documented in Section 8.2 of the datasheet.
What supply voltage options does MLX90380LGO-BAB-405-RE support?
The MLX90380LGO-BAB-405-RE supports both 3.3 V (3.135–3.6 V) and 5 V (4.5–5.5 V) operating supply voltages. Pins VDD3V3_A/B and VDD5V_A/B are separate; only one supply rail should be active at a time, with the unused rail left floating per Section 9.2 and Figure 12–13 of the datasheet.
How is the 40 mT full-scale range implemented in MLX90380LGO-BAB-405-RE?
The 40 mT full-scale magnetic range in MLX90380LGO-BAB-405-RE is factory-programmed via the '405' suffix ('4' = 40 mT range, '05' = high-bandwidth mode), calibrated for NdFeB magnets. It defines the in-plane flux density yielding ±40% VDD output swing at 25°C, as specified in Table 2 and Section 12 of the datasheet.
Does MLX90380LGO-BAB-405-RE provide functional safety support?
Yes, MLX90380LGO-BAB-405-RE implements dual-die redundancy in TSSOP-16 packaging with independent COS/SIN outputs (OUT1_A/OUT2_A and OUT1_B/OUT2_B), enabling cross-checking and fault detection required for ASIL-B/C systems. Its design aligns with ISO 26262 requirements for position sensing in automotive EPS and traction inverters.
Can MLX90380LGO-BAB-405-RE be programmed after soldering?
No, MLX90380LGO-BAB-405-RE is pre-programmed at wafer/test level with fixed parameters: X/Z axis, 40 mT range, NdFeB magnet type, and high-bandwidth mode. Programming through the connector is only supported on non-preprogrammed variants (e.g., those with '000' option codes); the '405' suffix indicates final factory configuration.
