Fairchild Semiconductor introduced what it claims as the world's first Smart Power Module (SPM) especially designed for driving single-phase switched reluctance motors (srm) for vacuum cleaners.

The new 50A-rated FCAS50SN60 SPM integrates a high-voltage ic (HVIC), low-voltage IC (LVIC), IGBTs, fast recovery diodes and a thermistor in a 44-by-26.8mm Mini-DIP package. According to the company, this package features Direct Bonded Copper (DBC) technology that significantly increases thermal performance. Compared to typical discrete solutions, Fairchild added, the FCAS50SN60 reduces power circuit space by up to 40 percent, enabling designers to incorporate the controller into the SRM assembly.

The UL-certified FCAS50SN60, with its built-in HVIC, provides an optocoupler-less, single-supply IGBT gate driving capability that further reduces overall system size. Additionally, its integrated under-voltage lock-out and short-circuit protection ensures high reliability. In addition to saving space, the SPM's Mini-DIP package with the DBC technology provides low thermal resistance (Rth(j-c) IGBT = 0.9C/W).

The FCAS50SN60 is priced at $30 each (100 pieces).
