International Rectifier's IR3103 motor drive IC, part of its iMOTION integrated design platform range, is a half-bridge FredFET with gate driver IC that does not require a heatsink for electronic motor drive applications up to 180 W.

Packaged in a sleek 11-pin mini SIP, the IR3103 simplifies the design of extremely compact, high performance two- and three-phase half-bridge inverter motor drives for appliances such as fans and refrigerator compressors.

"The transition away from noisy and inefficient motor controls based on triacs to quieter, more efficient and compact controls are made possible with the IR3103. Our latest solution simplifies the transition to more efficient, variable speed driver designs for low power appliance products and shrinks the footprint," said David Tam, vice president of IR's Consumer and Industrial group.

Propagation delays for the high- and low-side power FredFET devices are matched for better synchronisation of switching characteristics and lower power dissipation. The device can operate up to a maximum input voltage rating of 500 V up to 150°C. The package features isolation ratings up to 1500 Vrms/min, and enables shorter inter-component connections, reducing unwanted EMI emissions. ESD protection is included on all leads, and a bootstrap diode for the high-side driver section is integrated into the IR3103. In addition, a single-polarity power supply is all that is needed to drive the internal circuitry, simplifying module use.

To accelerate the design process and demonstrate the features of the IC, IR offers the IRADK31 demo kit. It includes a complete three-phase 250 W motor drive system controlled by graphical user interface software. The software can compare several motor control drive strategies for traditional AC induction motors as well as advanced brushless DC motors.
