FSBF15CH60BT-F166

Overview

The FSBF15CH60BT is a Motion SPM® 3 Series intelligent power module designed for three-phase AC induction, BLDC, and PMSM motor drives. It integrates a 600 V, 15 A IGBT inverter with optimized gate drivers and comprehensive protection features. Key electrical parameters include a collector-emitter saturation voltage of 2.2 V at 15 A, a forward voltage of 2.5 V for the freewheeling diode, and an isolation rating of 2500 V rms. The module supports active-HIGH logic inputs compatible with 3.3 V or 5 V systems, operates within a junction temperature range of -40°C to 150°C, and provides short-circuit protection on low-side IGBTs.

Feature Summary

• Integrates a fully featured 3-phase IGBT inverter with optimized gate drive circuits to minimize electromagnetic interference and switching losses.
• Includes built-in under-voltage lockout (UVLO) for both high-side and low-side supplies, along with short-circuit protection and fault reporting capabilities.
• Features separate negative DC-link terminals for each phase to facilitate precise three-phase current sensing for advanced control algorithms.
• Incorporates dedicated bootstrap diodes and Vs pins to simplify printed circuit board layout and reduce external component count.

Applications

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

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official database, as Fairchild part numbers were migrated to ON Semiconductor nomenclature during integration. Confirm that the specific package marking and packing type match your assembly requirements. Ensure compliance with RoHS standards and check for any recent lifecycle status updates regarding availability or obsolescence before finalizing procurement plans.

Selection Notes

Select this module when designing three-phase motor drives requiring integrated protection and current sensing capabilities. Ensure the application voltage does not exceed the 400 V recommended operating limit and that the control logic matches the active-HIGH input specifications. Verify thermal management strategies to maintain case temperatures within the specified operational range for reliable long-term performance.

Part Context

This component belongs to the Motion SPM® 3 Series, which consolidates power switching, gate driving, and protection functions into a single compact package. Originally developed by Fairchild Semiconductor, the product line was integrated into ON Semiconductor's portfolio following corporate acquisition. The series is engineered to provide high-performance inverter output stages for various motor types while simplifying system design through reduced external component requirements.

Replacement Considerations

Consult the official ON Semiconductor cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with the 600 V / 15 A rating and the SPMJA-027 package footprint. Verify that alternative devices support the same isolation voltage and protection feature set required by the original design.

FAQ

Does the short-circuit protection function on all phases?

No, the internal short-circuit protection circuitry is implemented only for the low-side IGBTs. High-side protection relies on other mechanisms such as UVLO.

What is the typical fault output pulse width?

The fault output pulse width is determined by an external capacitor connected between the CFOD pin and COM. For example, a 33 nF capacitor results in a typical pulse width of 1.8 ms.

Can the module be driven directly by an MCU without optocouplers?

Yes, the module integrates a high-speed HVIC that allows direct coupling to MCU terminals using standard CMOS or LSTTL outputs, eliminating the need for optical or transformer isolation.
