IR Unveils New IR3101 Integrated Half-Bridge Inverter

International Rectifier Corp. (IR, El Segundo, CA) introduced the IR3101, a high-performance, integrated half-bridge inverter for appliance motor drive applications. The IR3101 simplifies half-bridge inverter designs for one-phase, two-phase or three-phase motor drives for refrigerator compressors, fans and pumps up to 400 W (up to 250 W 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 that deliver low di/dt gate drive for better noise immunity and low losses. The device can operate up to the maximum input-voltage rating of 500 V up to 150 degrees C. The fully isolated MiniSIP package includes ESD protection on all leads, and has isolation ratings to 1,500 Vrms/min.

The new IR3101 is available immediately. Pricing begins at $2.50 each in 10,000-unit quantities.
