FSBB30CH60DF Motion SPM(R) 3 Series Features General Description * UL Certified No. E209204 (UL1557) FSBB30CH60DF is an advanced Motion SPM(R) 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 logiclevel 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. * 600 V - 30 A 3-Phase IGBT Inverter with Integral Gate Drivers and Protection * Low-Loss, Short-Circuit Rated IGBTs * Very Low Thermal Resistance Using Al2O3 DBC Substrate * Built-In Bootstrap Diodes and Dedicated Vs Pins Simplify PCB Layout * Separate Open-Emitter Pins from Low-Side IGBTs for Three-Phase Current Sensing * Single-Grounded Power Supply * LVIC Temperature-Sensing Built-In for Temperature Monitoring * Isolation Rating: 2500 Vrms / 1 min.

Typical Application Circuit Note: 14. To avoid malfunction, the wiring of each input should be as short as possible. (less than 2 - 3 cm) 15. VFO output is open-drain type. This signal line should be pulled up to the positive side of the MCU or control power supply with a resistor that makes IFO up to 2 mA. Please refer to Figure 14. 16. Input signal is active-HIGH type. There is a 5 k resistor inside the IC to pull-down each input signal line to GND. RC coupling circuits should be adopted for the prevention of input signal oscillation. R1C1 time constant should be selected in the range 50 ~ 150 ns. (Recommended R1 = 100 , C1 = 1 nF) 17. Each wiring pattern inductance of A point should be minimized (Recommend less than 10nH). Use the shunt resistor R4 of surface mounted (SMD) type to reduce wiring inductance. To prevent malfunction, wiring of point E should be connected to the terminal of the shunt resistor R4 as close as possible. 18. To prevent errors of the protection function, the wiring of B, C, and D point should be as short as possible. 19. In the short-circuit protection circuit, please select the R6C6 time constant in the range 1.5 ~ 2 s. Do enough evaluaiton on the real system because short-circuit protection time may vary wiring pattern layout and value of the R6C6 time constant. 20. Each capacitor should be mounted as close to the pins of the Motion SPM(R) 3 product as possible. 21. To prevent surge destruction, the wiring between the smoothing capacitor C7 and the P & GND pins should be as short as possible. The use of a high-frequency non-inductive capacitor of around 0.1 ~ 0.22 F between the P & GND pins is recommended. 22. Relays are used at almost every systems of electrical equipments at industrial application. In these cases, there should be sufficient distance between the CPU and the relays. 23. The zener diode or transient voltage suppressor should be adopted for the protection of ICs from the surge destruction between each pair of control supply terminals (Recommanded zener diode is 22 V / 1 W, which has the lower zener impedance characteristic than about 15 ). 24. C2 of around 7 times larger than bootstrap capacitor C3 is recommended. 25. Please choose the electrolytic capacitor with good temperature characteristic in C3. Also, choose 0.1 ~ 0.2 F R-category ceramic capacitors with good temperature and frequency characteristics in C4.
