FSAM20SM60A is a Motion SPM® 2 series that onsemi 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 drive matched to low-loss IGBTs. Effective over-current protection is realized through advanced current sensing IGBTs. The system reliability is further enhanced by the built-in thermistor and integrated under-voltage lock-out protection. In addition the incorporated HVIC facilitates the use of single-supply voltage without any negative bias. Inverter leg current sensing can be implemented because of three separate nagative dc terminals.
