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.
IR’s new µIPMTM 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.

Qualifying Questions
• Is the customer interested in?
- A compact solution
- Ease-of-use
- Improved thermal performance
- Reduction in overall system cost
Key Points
• The µIPMTM family offers a new benchmark in size versus any equivalent competitor solutions; up to 60%
smaller than the existing smallest 3-phase motor control Power ICs.
• House in QFN-like packages, the µIPMTM family is comprised of a series of fully integrated 3-phase or single-
phase (half-bridge) motor control circuit solutions. By adopting the most rugged and efficient high voltage
FREDFET MOSFET switches, specifically optimized for variable frequency drives, and IR’s most advanced HV
driver ICs, the µIPMTM product family has ratings ranging from 0.4A to 10A.
• With the µIPMTM 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 µIPMTM 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 µIPM™ 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.

Competition
Figures 1 and 2 compare the performance of the IRSM636-015MB versus the Fairchild FSB50x50 family of
modules, driving the same motor at identical bias and switching conditions. Tests were performed without an
external heat sink. A lower ΔTCA indicates better performance, while a missing bar indicates that the module was
unable to drive the motor at the specified switching frequency.
Figure 3 compares the performance of the IRSM836-015MB versus the Mitsubishi M81500FP module driving the
same motor at identical bias and switching conditions. Tests were performed without an external heat sink. A lower
ΔTCA indicates better performance, while a missing bar indicates that the module was unable to drive the motor at
the specified switching frequency.
