EL SEGUNDO, Calif. February 2004 - International Rectifier, IR® (NYSE: IRF) today introduced the IR3101, a high performance, integrated half-bridge inverter for appliance motor drive applications. The IR3101 simplifies half-bridge inverter designs for one-, two- or three-phase motor drives for refrigerator compressors, fans and pumps up to 400W (up to 250W with no heat-sink cooling).
The IR3101 is a complete driver IC with proprietary HVIC and latch immune CMOS technologies. The output features two built-in HEXFET® power MOSFETs with ultra-fast recovery body diode characteristics (FredFET) that deliver low di/dt gate drive for better noise immunity and low losses.
Mor Hezi, International Rectifier Marketing Manager for the Consumer and Industrial Business Unit, said, "Because the IR3101 is so small, component layout can be optimized for smaller PCB space, reducing unwanted EMI emissions. In addition, designers using the new device can save design time and reduce component count."
Propagation delays for the high- and low-side power FredFET devices are matched for better synchronized switching characteristics and lower output distortion. The device can operate up to the maximum input voltage rating of 500V up to 150°Celsius. The fully-isolated MiniSIP package includes ESD protection on all leads and has isolation ratings to 1500Vrms/min.
