FNA41060B2

Overview

The FNA41060B2 is a Motion SPM® 45 Series integrated power module designed for three-phase AC induction, BLDC, and PMSM motor drives. It integrates six short-circuit-rated IGBTs with freewheeling diodes, optimized gate drivers, and protection circuits within a ceramic substrate package. Key electrical ratings include a 600 V collector-emitter voltage (VCES), a 10 A continuous collector current per IGBT at 25°C case temperature, and a maximum supply voltage of 450 V. The module features separate open-emitter pins for low-side IGBTs to facilitate three-phase current sensing.

Feature Summary

• Integrates high-speed HVIC gate drivers that translate logic-level inputs to drive robust IGBTs while minimizing EMI and switching losses.
• Includes comprehensive on-module protection mechanisms such as under-voltage lockouts for both high-side and low-side supplies, short-circuit shutdown, and thermal monitoring via a built-in NTC thermistor.
• Features UL certification and an isolation rating of 2000 Vrms between the power circuit and the heat sink plate.
• Provides dedicated negative DC-link input terminals for each phase to support diverse control algorithms and simplify PCB layout.

Applications

• Motion control systems for home appliances
• Industrial motor drives
• AC Induction motor inverters
• BLDC and PMSM motor output stages

Procurement Notes

Verify the specific ordering suffix B2 corresponds to the long lead terminal type (SPMAA-C26) rather than the standard dual form (SPMAA-A26). Confirm compliance with RoHS standards and REACH SVHC requirements prior to integration. Ensure the application design accounts for the recommended mounting torque of 0.7 N·m to prevent ceramic substrate damage due to uneven stress or over-tightening.

Selection Notes

Select this module for applications requiring a fully featured inverter stage with integrated protection and single-grounded power supply capabilities. It is optimized for switching frequencies around 5 kHz but supports up to 20 kHz. Ensure the control interface matches the active-HIGH logic levels compatible with 3.3 V or 5 V microcontrollers without requiring external optocouplers.

Part Context

This component belongs to the Motion SPM® 45 Series family from onsemi. It serves as a complete inverter output stage solution, combining power semiconductors and control ICs into a single ceramic package. The series is engineered to reduce system complexity by integrating bootstrap diodes and dedicated bias grounds, distinguishing it from discrete transistor assemblies.

Replacement Considerations

The FNA41060 is the primary variant within this series, differing primarily in package terminal configuration (standard vs. long lead). No other cross-model substitutes are documented in the provided datasheet.

FAQ

Does the FNA41060B2 support direct coupling to microcontrollers?

Yes, the integrated HVIC allows direct coupling to MCU terminals without optocouplers or transformers, provided the input signals match the active-HIGH logic levels.

Where is the short-circuit protection implemented?

Short-circuit protection is functioning only at the low-side IGBTs, utilizing the CSC pin for current detection and fault signaling.

What is the purpose of the NU, NV, and NW pins?

These are separate negative DC-link input terminals for each phase, designed to support the widest variety of control algorithms and enable three-phase current sensing.
