Key Message With more than 200 million motors featuring a power range below 750W, the opportunity for energy savings through the adoption of electronically controlled variable speed solutions is very significant. In fact, 55% of the total electric energy produced today is used to run motors of every size, shape and efficiency. Since variable speed drives can save as much as 70% of the energy costs by varying the speed of the load, inevitably, new energy efficiency standards for fans and pumps demand the adoption of electronic controlled motors. TM IR's new IPM family represents the latest example of IR's commitment to develop energy saving products and solutions and provides the engineering community with simpler, easier and more efficient ways to design and release products that meet customers' needs and regulatory standards. The two new devices, IRSM808105MH and IRSM807-105MH, are optimized for high efficiency appliance and light industrial applications with motor power up to 300W.

By adopting the most rugged and efficient high voltage FREDFET MOSFET switches, specifically optimized for variable frequency drives, and IR's most advanced HV TM driver ICs, the IPM product family has ratings ranging from 0.4A to 10A. * With the IPM family, designers can implement smaller and more efficient motor drives solutions for embedded applications where high volume and higher density is required. By using QFN packaging technology, assembly is simplified by eliminating through-hole second pass assembly and improving thermal performances versus the traditional dual in-line module solution from the competition. * The IPM product family offers a scalable solution for applications that require different current ratings by delivering a wide spectrum of parts with common pin-out and package size, optimized to address specific load power levels. * The IRSM808-105MH and IRSM807-105MH half-bridge IPMTM power modules provide designers with even greater scalability, in addition to offering up to a 60% smaller footprint compared to existing leading solutions and delivering advantages in output current capability and system efficiency cost-effectively.
