FSBB30CH60D is an advanced Motion SPM® 3 module providing a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, thermal monitoring of drive IC, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s internal IGBTs.

Separate negative IGBT terminals are available for each phase to support the widest variety of control algorithms.

SPM3 FSBB30CH60D马达驱动参考设计

The SPM3 design objective is to provide a minimized package and a low power consumption module with improved reliability. This is achieved by applying new gate-driving high-voltage integrated circuit (HVIC), a new insulated-gate bipolar transistor (IGBT) of advanced silicon technology, and improved direct bonded copper (DBC) substrate base transfer mold package. Motion SPM 3 achieves reduced board size and improved reliability compared to existing discrete solutions. Target applications are inverterized motor drives for industrial use, such as air conditioners, general-purpose inverters and serve motors.

The temperature sensing function of SPM3 version 5 products is implemented in the LVIC to enhance the system reliability. An analog voltage proportional to the temperature of the LVIC is provided for monitoring the module temperature and necessary protections against over-temperature situations. Figure 1 show the package outline structure.
