It should be used in conjunction with the FSBB20CH60 data sheet and Fairchild’s SPM application note AN-9035. Product Description Fairchild’s Smart power Module SPM products provide motor control for energyrestricted low-power inverter-driven applications, such as washing machines and air conditioners. The FSBB20CH60 Motion-SPM integrates three high-voltage ICs HVICs , one low-voltage IC LVIC , six IGBTs for three-phase inverter and six fast recovery diodes. Fairchild’s Motion-SPM reduces board space by utilizing an ultra-compact 44mm x 26.8mm Mini-DIP package and by incorporating built-in HVICs that provide an optocoupler-less, single supply IGBT gate driving capability. The FSBB20CH60 product offers designers high reliability with integrated under-voltage lock out UVLO and short circuit SC protection. Circuit Description The Motion-SPM is installed as the switching module in this evaluation board and has direct interface with the CPU using one shunt resistor. The DC-link P and N input terminals are connected into the corresponding terminals in Motion-SPM and three-phase U,V,W output terminals from SPM are wired into motor input. Since the three HVICs are integrated in the Motion-SPM, 3 parts of bootstrap circuit are needed, which consists of bootstrap capacitor, charge resistor for charging boost capacitor, blocking diode for high voltage isolation. One shunt resistor is used for sensing short current and the related short current circuit is composed of an external shunt resistor and R-C low pass The signal of fault output pin VFO drops from high level to low when a fault, such as UV Under Voltage or SC Short Circuit , happens. A pull-up resistor and capacitor are needed to support this action. Six R-C low pass are used between input connector from a DSP controller or other controllers and gate input signal pins of Motion-SPM. 2006 Fairchild Semiconductor Page 3 of 10 Designed Solution Schematic 2006 Fairchild Semiconductor Gating UH Gating VH Gating WH Gating UL Gating VL Gating WL Fault Test Board 15V line 5V line 15V line 10 15V 11 GND 15V 10 GND 11 5V line 15V line C24 100µF D3 R9* 1N4937 R19 100 1/8W R18 100 1/8W C3 102 C2 102 R17 100 1/8W C1 102 R16 100 1/8W D2 R8* 1N4937 1N4937 C14*
