FSBB20CH60CT Smart Power Module May 2009 FSBB20CH60CT Smart Power Module Features • UL Certified No.E209204(SPM27-CC package) • Very low thermal resistance due to using DBC • Easy PCB layout due to built in bootstrap diode • 600V-20A 3-phase IGBT inverter bridge including control ICs for gate driving and protection • Divided negative dc-link terminals for inverter current sensing applications • Single-grounded power supply due to built-in HVIC • Isolation rating of 2500Vrms/min. Motion-SPM General Description TM It is an advanced motion-smart power module (Motion-SPMTM) that Fairchild has newly developed and designed to provide very compact and high performance ac motor drives mainly targeting low-power inverter-driven application like air conditioner and washing machine. It combines optimized circuit protection and drive matched to low-loss IGBTs. System reliability is further enhanced by the integrated under-voltage lock-out and short-circuit protection. The high speed built-in HVIC provides opto-coupler-less single-supply IGBT gate driving capability that further reduce the overall size of the inverter system design. Each phase current of inverter can be monitored separately due to the divided negative dc terminals. Applications • AC 100V ~ 253V three-phase inverter drive for small power ac motor drives • Home appliances applications like air conditioner and washing machine Top View Bottom View 44mm 26.8mm Figure 1. ©2009 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FSBB20CH60CT Rev.

The SPM input signal section integrates 5kΩ (typ.) pull-down resistor. Therefore, when using an external filtering resistor, please pay attention to the signal voltage drop at input terminal. 2) The logic input is compatible with standard CMOS or LSTTL outputs.

(less than 2-3cm) 2) By virtue of integrating an application specific type HVIC inside the SPM, direct coupling to CPU terminals without any opto-coupler or transformer isolation is possible. 3) VFO output is open collector type. This signal line should be pulled up to the positive side of the 5V power supply with approximately 4.7kΩ resistance. Please refer to Figure11. 4) CSP15 of around 7 times larger than bootstrap capacitor CBS is recommended. 5) VFO output pulse width should be determined by connecting an external capacitor(CFOD) between CFOD(pin7) and COM(pin2). (Example : if CFOD = 33 nF, then tFO = 1.8ms (typ.)) Please refer to the note 5 for calculation method. 6) Input signal is High-Active type. There is a 5kΩ 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. RSCPS time constant should be selected in the range 50~150ns. CPS should not be less than 1nF.(Recommended RS=100Ω , CPS=1nF) 7) To prevent errors of the protection function, the wiring around RF and CSC should be as short as possible. 8) In the short-circuit protection circuit, please select the RFCSC time constant in the range 1.5~2μs. 9) Each capacitor should be mounted as close to the pins of the SPM as possible. 10) To prevent surge destruction, the wiring between the smoothing capacitor and the P&GND pins should be as short as possible. The use of a high frequency non-inductive capacitor of around 0.1~0.22μF between the P&GND pins is recommended. 11) Relays are used at almost every systems of electrical equipments of home appliances. In these cases, there should be sufficient distance between the CPU and the relays. 12) CSPC15 should be over 1μF and mounted as close to the pins of the SPM as possible. Figure 13.
