Product details
Overview
MLX90380LGO-BAC-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 Ferrite magnet sensitivity (70 mT full-scale range) in TSSOP-16 package for end-of-shaft or through-shaft motor rotor position feedback.
For engineers reviewing the MLX90380LGO-BAC-100-RE datasheet, pinout, applications, or equivalent options, this page delivers verified technical context, exact pin functions, magnetic axis configuration (Z/Y), bandwidth setting (high BW), and real-world selection guidance for BLDC and PMSM field-oriented control systems requiring high-temperature robustness and analog resolver interface compatibility.
Technical Context
The MLX90380LGO-BAC-100-RE implements Triaxis® Hall technology to simultaneously sense orthogonal (Z) and in-plane (Y) magnetic flux components, generating synchronized COS and SIN outputs referenced to VDD. Its dual-die TSSOP-16 architecture provides full redundancy with independent power domains (VDD3V3_A/VDD5V_A and VDD3V3_B/VDD5V_B) and isolated ground paths (VSS_A/VSS_B).
This variant is preprogrammed for Z/Y magnetic axis configuration, high-bandwidth operation (5V supply, 125 kHz Nyquist frequency), and 70 mT full-scale range using Ferrite magnets - enabling direct integration into high-speed motor control loops where tracking delay is limited to 12 µs and total angular error with dynamic compensation remains within ±1°.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Refresh Rate | 4 µs - enables real-time angle computation at up to 250 kSPS for high-RPM motor control |
| Operating Temperature | -40°C to 150°C - supports under-hood automotive and industrial motor drive environments |
| Supply Voltage | 5 V nominal (VDD5V pins) - powers both die independently; VDD3V3 pins must be left floating |
| Magnetic Range | 70 mT full-scale - optimized for Ferrite magnets per BAC option code, yielding ~0.57 %VDD/mT sensitivity |
| Output Type | Ratiometric sine/cosine analog - outputs scale linearly with VDD, simplifying ADC reference alignment |
| Angular Accuracy | ±1° total error with dynamic compensation - achieved via off-chip arctan(OUT2/OUT1) with offset/gain correction |
| Tracking Delay | 12 µs - minimum latency between magnetic rotation and updated COS/SIN outputs under high-BW mode |
Pinout & Package
TSSOP-16 package with dual-die fully redundant architecture; 16-pin surface-mount footprint measuring 5.0 mm × 4.4 mm × 1.2 mm (max height), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 9 | VSS_A / VSS_B | Separate ground returns for Die A and Die B - mandatory for EMC integrity and redundancy isolation |
| 5, 13 | OUT2_B / OUT2_A | Sine analog outputs - each die provides independent SIN signal for fault-tolerant angle decoding |
| 8, 16 | OUT1_B / OUT1_A | Cosine analog outputs - paired with respective OUT2 pins to form redundant resolver quadrature pairs |
| 6, 14 | VDD5V_B / VDD5V_A | 5 V supply inputs - must be driven; VDD3V3 pins (7, 15) are unused and left floating in 5V mode |
| 4, 11 | TEST_A / TEST_B | Factory test pins - connect to GND for optimal EMC; not user-accessible in normal operation |
| 2, 3, 10, 12 | NC | No-connect pins - internally unconnected; tie to GND per datasheet for noise suppression |
Key Features
| Feature | Design Value |
|---|---|
| Triaxis® Hall Sensing | Simultaneous orthogonal (Z) and in-plane (Y) flux detection enables true 3D magnetic field resolution without external concentrators |
| Z/Y Magnetic Axis | Preconfigured for Z/Y orientation - OUT1 = COS(Z), OUT2 = SIN(Y), supporting through-shaft multi-pole magnet configurations |
| Ferrite Magnet Optimization | BAC-100 option sets 70 mT full-scale range and 2000 ppm/°C sensitivity temperature coefficient for Ferrite stability over temperature |
| High-Bandwidth Mode | 5V supply + high-BW programming yields 125 kHz Nyquist frequency and 12 µs tracking delay - critical for >15,000 RPM motors |
| Dual-Die Redundancy | Independent A/B die with separate power, ground, and outputs - supports ASIL-D functional safety architectures via cross-checking |
Applications
| Brushless DC Motor Control | Permanent Magnet Synchronous Motor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resolver replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90380LGO-BAB-100-RE | Uses NdFeB magnet (60 mT range, 1100 ppm/°C TCS) instead of Ferrite; same Z/Y axis and high-BW mode | Better low-temperature sensitivity stability but reduced high-temp flux retention vs. Ferrite | Select when magnet cost and low-T performance outweigh 150°C long-term flux decay concerns |
| MLX90380LDC-BAC-100-RE | SOIC-8 single-die version - identical Ferrite 70 mT range and Z/Y axis, but no redundancy or dual-output capability | Lacks fault tolerance; suitable only for non-safety-critical, space-constrained designs | Choose for cost-sensitive, non-ASIL applications where PCB area is premium and redundancy is unnecessary |
Compared with MLX90380LGO-BAB-100-RE, this part trades NdFeB sensitivity stability for superior high-temperature magnetic retention; compared with MLX90380LDC-BAC-100-RE, it adds full die-level redundancy and independent output channels at the cost of larger footprint and higher BOM count - essential for ASIL-D motor control.

FAQ
What magnetic axis configuration is implemented in MLX90380LGO-BAC-100-RE?
The MLX90380LGO-BAC-100-RE is factory-programmed for Z/Y magnetic axis configuration, meaning OUT1 carries the cosine of the Z-axis magnetic field component and OUT2 carries the sine of the Y-axis component. This orientation supports through-shaft multi-pole magnet arrangements and is confirmed by the BAC option code's third digit '0', indicating Z/Y equal sensitivity per datasheet Table 2.
Does MLX90380LGO-BAC-100-RE support both 3.3 V and 5 V supply operation?
No - MLX90380LGO-BAC-100-RE is configured for 5 V operation only, as indicated by the '1' in the second digit of its option code (BAC-100). The '1' specifies 5 V supply voltage with high bandwidth; VDD3V3 pins (7 and 15) must remain unconnected and floating, while VDD5V pins (6 and 14) must be powered.
What is the full-scale magnetic range and sensitivity type for MLX90380LGO-BAC-100-RE?
The MLX90380LGO-BAC-100-RE has a 70 mT full-scale magnetic range and uses Ferrite magnets, as defined by the 'C' in BAC. Its typical sensitivity is 0.57 %VDD/mT, with a first-order sensitivity temperature coefficient of 2000 ppm/°C to compensate Ferrite's thermal flux degradation.
How does the dual-die architecture of MLX90380LGO-BAC-100-RE enhance system reliability?
The MLX90380LGO-BAC-100-RE integrates two fully independent sensor dies in one TSSOP-16 package, each with dedicated power (VDD5V_A/VDD5V_B), ground (VSS_A/VSS_B), and analog outputs (OUT1_A/OUT2_A and OUT1_B/OUT2_B). This enables hardware-level cross-checking for fault detection, satisfying ASIL-D requirements in automotive EPS and traction inverters.
Can MLX90380LGO-BAC-100-RE be used with existing resolver-to-digital converter (RDC) ICs?
No - MLX90380LGO-BAC-100-RE outputs ratiometric analog sine/cosine voltages (0–100% VDD), not the differential excitation and feedback signals required by traditional RDCs. It interfaces directly with MCU ADCs; signal conditioning is limited to filtering, and angle computation occurs digitally via arctan(OUT2/OUT1) with optional dynamic compensation.
