INTERNATIONAL Rectifier has released the IR3101, an 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.
It is a complete driver IC with HVIC and latch immune CMOS technologies. The output features two built-in HEXFET power MOSFETs with ultra-fast recovery body diode characteristics (FredFET). The MOSFETs deliver low di/dt gate drive for better noise immunity and low losses.
The small size of the inverter allows component layout to be optimised for smaller PCB space, reducing unwanted EMI emissions. Designers using the new device can also save design time and reduce component count.
Propagation delays for the high side and low side power FredFET devices are matched for better synchronised switching characteristics and lower output distortion. The device can operate up to a maximum input voltage rating of 500V up to 150°C. The fully-isolated MiniSIP package includes ESD protection on all leads and has isolation ratings to 1500Vrms/min.
