FCAS20DN60BB
Smart Power Module for SRM Features
* 600V-20A 2-phase asymmetric bridge IGBT converter for SRM drive including control ICs for gate driving and protection * Single-grounded power supply due to built-in HVIC * Isolation rating of 1500Vrms/min. * Embedded bootstrap diode in the package
General Description
FCAS20DN60BB 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 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 shortcircuit protection. The high speed built-in HVIC provides optocoupler-less IGBT gate driving capability that further reduce the overall size of the system. In addition the incorporated HVIC facilitates the use of single-supply drive topology enabling the FCAS20DN60BB to be driven by only one drive supply voltage without negative bias.
Applications
* 2-phase SRM drives for home application vacuum cleaner.
