FCAS50SN60 is an advanced smart power module for SRM drive that Fairchild has newly developed and designed to provide very compact and high performance SRM motor drives mainly targeting low-power inverter-driven SRM application especially for a vacuum air cleaner. 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 IGBT gate driving capability that further reduce the overall size of the inverter system design. In addition the incorporated HVIC facilitates the use of single-supply drive topology enabling the FCAS50SN60 to be driven by only one drive supply voltage without negative bias. Each phase current of inverter can be monitored separately due to the divided negative dc terminals.

• Very low thermal resistance due to using DBC
• 600V-50A single-phase asymmetric bridge IGBT converter for SRM drive 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
• Switching frequency of 2.2~8kHz
• Isolation rating of 2500Vrms/min.

• AC 200V ~ 242V single-phase SRM drives for home application vacuum cleaner.
