Fairchild Semiconductor's Motion-Smart Power Modules -SPM- Offer Increased Space, Efficiency and Reliability Benefits for Low-Power Appliance Motor Drives.

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

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."

Each Motion-SPM uses advanced FRFET and HVIC devices to ensure the performance and long-term reliability of the end product, while simplifying motor inverter designs. The Motion-SPMs' FRFETs optimize system efficiency by lowering switching and conduction losses during low-current conditions. For ruggedness, they provide a wider reverse bias safe operating area (RBSOA) than IGBTs of similar ratings. By using the MOSFETs' body diodes as freewheeling diodes, Motion-SPMs eliminate the need for additional components, improving the efficiency and noise immunity. The gate-driver ICs increase reliability through high-isolation, 5 V CMOS/TTL interface and under-voltage lockout (UVLO) protection features.

Additional features of the Motion-SPM series streamline the design process. The HVICs' high-speed level-shifting function permits operation from a single power supply voltage, a technique that makes space-consuming opto-isolation unnecessary. By providing optimal control of switching speeds, Motion-SPMs lower electromagnetic interference (EMI), enabling designers to decrease the design costs related to reducing noise. In addition, these modules save space while increasing reliability by offering three divided negative DC-link terminals for inverter current sensing.

The 500 V FSB50250 and FSB50450 (2 A- and 3 A-rated, respectively) are each housed in a 23-lead DIP. These products are lead-free (Pb-free).

With this introduction of low-power SPM products, Fairchild now offers the most comprehensive portfolio of power modules covering the full range of 50 W to 3 kW appliances. The Motion-SPM series represent the way Fairchild uses its design and manufacturing expertise, as well as a deep understanding of the markets it serves, to offer both integrated and non-integrated solutions that meet specific application requirements.
