Rated from 50 W to 3 kW, Motion-SPM(TM) 500 V multi-chip Models FSB50250 and FSB50450 each combine 6 fast recovery MOSFET's and 3 half-bridge high-voltage ICs in one thermally efficient, Tiny-DIP package designed for BLDC motors with built-in control. Gate-driver ICs offer high-isolation, 5 V CMOS/TTL interface and under-voltage lockout protection. High-speed level-shifting function permits operation from single power supply voltage, eliminating need for opto-isolation.

Fairchild's SPM portfolio is the industry's most comprehensive line-up of power modules--50 W to 3 kW--for inverter motors

South Portland, Maine-June 8, 2005-Fairchild Semiconductor's (NYSE: FCS) Motion-Smart Power Modules (SPM(TM)) offer a highly integrated solution for low-power (below 100 W), brushless dc (BLDC) motor applications. The Motion-SPM devices integrate multiple functions in a single compact package, offering a simplified motor drive solution to speed engineering design, reduce PC board space and enable energy-efficient and reliable designs in home appliances. Motion-SPM multi-chip modules combine six fast recovery MOSFETs (FRFET(TM)) and three half-bridge high-voltage ICs (HVIC) in one thermally efficient, ultra-compact (29 mm x 12 mm) Tiny-DIP package designed for BLDC motors with built-in control.

"The low-power appliance market is selecting high-voltage brushless dc (BLDC) motors over single-phase AC induction motors, due to their increased efficiency (from 50 to 90%), decreased acoustic noise and vibration, and higher power density per volume and weight. Fairchild's Motion-SPMs make it possible to build the motor control into the BLDC assembly," said Taehoon Kim, vice president of Fairchild's High-Power product line. "By integrating power analog and power discrete IC functionality into a single package, the SPM represents how Fairchild understands--and meets--the thermal efficiency, reliability and board space demands of the home appliance market. In addition to offering advantages over non-integrated solutions, the new Motion-SPM series makes Fairchild's SPM portfolio the industry's most comprehensive line-up of power modules covering inverter motors used in a full range of 50 W to 3 kW appliances."
