Power modules cut the budget for DC motor drives
Fairchild Semiconductor's Motion-Smart Power Modules (SPMs) offer a highly integrated solution for low-power (sub-100W), 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 multichip modules combine six fast recovery MOSFETs (FRFET) and three half-bridge high-voltage ICs (HVIC) in one thermally efficient, ultracompact (29 x 12mm) 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 analogue 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 nonintegrated solutions, the new Motion-SPM series makes Fairchild's SPM portfolio the industry's most comprehensive lineup of power modules covering inverter motors used in a full range of 50W to 3kW 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.
