FSBM20SL60 is an advanced smart power module (SPM)
that Fairchild has newly developed and designed to provide
very compact and high performance ac motor drives mainly
targeting low speed low-power inverter-driven application
like air conditioners. It combines optimized circuit protection
and drive matched to low-loss IGBTs. Highly effective
short-circuit current detection/protection is realized through
the use of advanced current sensing IGBT chips that allow
continuous monitoring of the IGBTs current. System
reliability is further enhanced by the integrated undervoltage lock-out 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 FSBM20SL60 to
be driven by only one drive supply voltage without negative
bias. Inverter current sensing application can be achieved
due to the divided negative dc terminals.
