General Description April 2014 FSBB10CH120D 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, 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 highvoltage, 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.

Typical Application Circuit 14. To avoid malfunction, the wiring of each input should be as short as possible. (less than 2-3 cm) 15. V FO 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 I FO up to 2 ma. Please refer to Figure Fault out pulse width can be adjust by capacitor C 5 connected to the C FOD terminal. 17. Input signal is active-high type. There is a 5 kw 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. R 1 C 1 time constant should be selected in the range 50 ~ 150 ns. (recommended R 1 = 100 Ω, C 1 = 1 nf) 18. Each wiring pattern inductance of point A should be minimized (recommend less than 10 nh). Use the shunt resistor R 4 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 R 4 as close as possible. 19. To prevent errors of the protection function, the wiring of B, C, and D point should be as short as possible. 20. In the short-circuit protection circuit, select the R 6 C 6 time constant in the range 1.0 ~ 1.5 ms. Do enough evaluaiton on the real system because short-circuit protection time may vary wiring pattern layout and value of the R 6 C 6 time constant. 21. Each capacitor should be mounted as close to the pins of the Motion SPM 3 product as possible. 22. To prevent surge destruction, the wiring between the smoothing capacitor C 7 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 mf between the P & GND pins is recommended. 23. Relays are used in most systems of electrical equipments in industrial application. In these cases, there should be sufficient distance between the MCU and the relays. 24. The Zener diode or transient voltage suppressor D 2 should be adapted 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 Ω). 25. Boostrap capacitor C 3 and Bootstrap resistor R 2 values depend on PWM control algorithm. And, C 2 of around seven times larger than bootstrap capacitor C 3 is recommended. 26. Please choose the electrolytic capacitor with good temperature characteristic in C 3. Choose 0.1 ~ 0.2 mf R-category ceramic capacitors with good temperature and frequency characteristics in C Use the bootstrap diode D 1 which has high voltage(v RRM = 1200 V or more), soft, and fast recovery(t RR = less than 100 ns) characteristics Fairchild Semiconductor Corporation 12
