FSBB20CH60 is a Motion SPM^??3 series that ON Semiconductor has developed to provide a very compact and high performance inverter solution for AC motor drives in low-power applications such as air conditioners. It combines optimized circuit protections and drives matched to low-loss IGBTs. The system reliability is further enhanced by the integrated under-voltage lock-out and over-current protection. The high speed built-in HVIC provides optocoupler- less single-supply IGBT gate driving capability that further reduces the overall size of the inverter system. Each phase leg current of the inverter can be monitored thanks to three separate negative dc terminals.
