Product details
Overview
MLX90380LDC-BAC-100-SP from Melexis is a monolithic Triaxis® contactless rotary position sensor IC delivering true 360° sine/cosine analog outputs with 4 µs output refresh rate, ±40%VDD swing, and ratiometric operation across 3.3 V or 5 V supply. It supports end-of-shaft and through-shaft configurations using ferrite magnets and operates from −40°C to +150°C in automotive and industrial motor control systems.
For engineers reviewing the MLX90380LDC-BAC-100-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-8 pin mapping, magnetic axis (X/Y), 10 mT full-scale range, and real-world motor control integration context - all confirmed from Melexis Revision 11 datasheet (June 2021).
Technical Context
The MLX90380LDC-BAC-100-SP implements Triaxis® Hall technology to simultaneously sense orthogonal (X/Y) and in-plane magnetic field components, enabling high-fidelity angular position reconstruction via arctangent computation of dual analog outputs. Its internal architecture includes programmable sample-and-hold filtering, factory-programmed sensitivity (10 mT range), and magnetic axis selection fixed to X/Y configuration per BAC option code.
This variant uses a single-die SOIC-8 package with dedicated VDD3V3/VDD5V supply pins, ratiometric analog outputs (OUT1 = COS, OUT2 = SIN), and on-chip EEPROM for calibration data storage. Output update timing is deterministic at 4 µs per field component, supporting up to 25,000 rpm mechanical rotation with ≤1.8° signal phase shift under high-bandwidth programming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - Enables real-time angular tracking at up to 25,000 rpm with minimal latency in field-oriented control loops. |
| Full-Scale Magnetic Range | 10 mT - Factory-programmed for ferrite magnets; delivers ±40%VDD output swing at TA = 25°C with VDD = 3.3 V. |
| Operating Supply | 3.3 V or 5 V - Dual-supply pin architecture (VDD3V3/VDD5V); only one supply active at a time; VDD3V3 must float in 5 V mode. |
| Magnetic Axis | X/Y - Fixed intrinsic axis configuration per BAC option code; supports end-of-shaft and on-axis multi-pole magnet applications. |
| Temperature Range | −40°C to +150°C - Qualified for under-hood automotive and industrial motor drive environments without derating. |
| Output Type | Ratiometric sine/cosine analog - OUT1 (COS) and OUT2 (SIN) scale linearly with VDD; enables direct ADC interfacing without external reference. |
| Total Angular Error | ±1° with dynamic compensation - Achievable via off-chip offset/gain/phase correction applied before arctan(OUT2/OUT1) computation. |
Pinout & Package
MLX90380LDC-BAC-100-SP is housed in an 8-pin SOIC package (JEDEC MS-012AC) with 1.27 mm pitch, 5.3 mm × 6.2 mm body, and exposed pad not connected internally. Pin 2 and Pin 4 are NC; Pin 3 (TEST) and unused pins must be tied to GND for optimal EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VSS | Supply Ground | Primary ground reference for analog and digital circuitry; must be low-impedance connection to system GND plane. |
| 2 NC | Not Connected | No internal connection; tie to GND per EMC recommendation to reduce radiated emissions. |
| 3 TEST | Test Pin | Factory test access; tie to GND in application to suppress noise coupling and improve immunity. |
| 4 NC | Not Connected | No internal connection; tie to GND per EMC recommendation. |
| 5 OUT2 | Analog Output SIN | Sine waveform output; ratiometric to VDD; drives ADC input directly with 0–100% VDD swing. |
| 6 VDD5V | 5 V Supply Input | Active 5 V supply rail; leave VDD3V3 floating when using this pin; supports 4.5–5.5 V operation. |
| 7 VDD3V3 | 3.3 V Supply Input | Active 3.3 V supply rail; leave VDD5V floating when using this pin; supports 3.135–3.6 V operation. |
| 8 OUT1 | Analog Output COS | Cosine waveform output; ratiometric to VDD; paired with OUT2 for high-resolution angular decoding. |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (X/Y) field measurement eliminates need for external flux concentrators or multi-sensor assemblies in compact motor encoders. |
| Programmable Filter Bandwidth | Customer-selectable via 4 application pins; enables matching of output dynamics to MCU ADC sampling rate and mechanical bandwidth requirements. |
| Ferrite Magnet Optimization | BAC option code configures sensitivity and temperature coefficient specifically for cost-effective ferrite magnets, reducing system BOM cost vs. SmCo/NdFeB. |
| Ratiometric Analog Outputs | Eliminates need for precision voltage references; OUT1/OUT2 scaling tracks VDD variations, improving robustness against supply ripple in noisy motor environments. |
| End-of-Shaft / Through-Shaft Flexibility | X/Y magnetic axis supports both axial (end-of-shaft) and radial (through-shaft) magnet placements without hardware redesign or sensor replacement. |
Applications
| Brushless Motor Rotor Position | Electric Power Steering (EPS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless rotary position sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LDC-BAA-100-SP | Uses SmCo magnet; higher TCS (350 ppm/°C) and tighter sensitivity accuracy (±5%) vs. ferrite-based BAC variant. | Better suited for high-precision PMSM control where magnet temperature stability dominates system error budget. | Select BAA if SmCo magnet is already deployed and thermal drift compensation is prioritized over cost. |
| MLX90380LDC-BAB-100-SP | Optimized for NdFeB magnets; intermediate TCS (1100 ppm/°C); sensitivity mismatch <5% with gain adjustment. | Preferred for BLDC motors using sintered NdFeB rotors where field strength and cost balance is critical. | Choose BAB when NdFeB magnets are used and higher sensitivity than ferrite is required without SmCo expense. |
Compared with MLX90380LDC-BAC-100-SP, the BAA variant offers superior thermal stability for SmCo systems but at higher magnet cost, while BAB provides higher sensitivity for NdFeB-based designs - all three share identical SOIC-8 pinout, X/Y axis, 4 µs update rate, and ratiometric analog interface.

FAQ
What is the magnetic axis configuration of MLX90380LDC-BAC-100-SP?
The MLX90380LDC-BAC-100-SP is factory-programmed for X/Y magnetic axis configuration, meaning OUT1 responds to the X-component and OUT2 to the Y-component of the applied magnetic field. This supports end-of-shaft and on-axis multi-pole magnet arrangements per Melexis datasheet Table 2 and Figure 6.
Does MLX90380LDC-BAC-100-SP support both 3.3 V and 5 V operation simultaneously?
No - MLX90380LDC-BAC-100-SP requires exclusive use of either VDD3V3 or VDD5V; both supplies must not be active at the same time. When using VDD5V (Pin 6), VDD3V3 (Pin 7) must be left floating, and vice versa, as specified in Section 9.1 and Figure 12/13 of the datasheet.
What is the full-scale magnetic range programmed in MLX90380LDC-BAC-100-SP?
The "100" suffix in MLX90380LDC-BAC-100-SP indicates a 10 mT full-scale magnetic range, optimized for ferrite magnets and valid only with 3.3 V supply (per Table 2 footnote 13). At TA = 25°C, this yields ±40%VDD output swing with VOQ = 50%VDD.
Can MLX90380LDC-BAC-100-SP be used with through-shaft magnet configurations?
Yes - the X/Y magnetic axis of MLX90380LDC-BAC-100-SP supports both end-of-shaft and through-shaft (off-axis) configurations, as confirmed in Section 2 Application Examples and Figure 2 of the datasheet. Mechanical placement must align the magnet's rotational plane with the IC's X/Y surface.
What is the maximum mechanical rotation speed supported by MLX90380LDC-BAC-100-SP?
MLX90380LDC-BAC-100-SP supports up to 25,000 rpm mechanical rotation speed with ≤1.8° signal phase shift under high-bandwidth programming mode, as specified in Table 8 Magnetic Specifications. This assumes proper magnet geometry, air gap, and external signal processing for arctan computation.
