Motor controller ICs

27 June 2012 Power Electronics / Power Management

International Rectifier introduced a family of highly integrated μIPM power modules for high-efficiency appliance and light industrial applications including compressor drives for refrigeration, pumps for heating and water circulation, air-conditioning fans, dishwashers and automation systems.

Available in a compact 12 x 12 x 0,9 mm PQFN package, the μIPM family comprises a series of fully integrated three-phase surface-mount motor control circuit solutions. The new approach pioneered by IR for this market segment utilises PCB copper traces to dissipate heat from the module, providing cost savings through a smaller package design and even eliminating the need for an external heatsink. By using standard packaging QFN technology, assembly is simplified by eliminating through-hole second pass assembly and improving thermal performance compared to traditional dual-in-line module solutions.

IR’s µIPM product family offers a scalable power solution with common pin-out and package size. Featuring rugged and efficient high-voltage FredFET MOSFET switches specifically optimised for variable frequency drives and IR’s most advanced high-voltage driver ICs, the μIPM product family offers DC current ratings ranging from 2 A to 4 A and voltages of 250 V and 500 V.
