General Description
It is an advanced motion-smart power module (Motion-SPMTM)
that Fairchild has newly developed and designed to provide
very compact and high performance ac motor drives mainly targeting low-power inverter-driven application like air conditioner
and washing machine. 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 single-supply IGBT gate driving capability that
further reduce the overall size of the inverter system design.
Each phase current of inverter can be monitored separately due
to the divided negative dc terminals.
