IR3103

A half-bridge FredFET with gate driver IC that does not require a heatsink for electronic motor drive applications up to 180 W

February 21st, 2010
  • Packaged in a 11-pin mini SIP
  • Suitable for the design of extremely compact, high performance two- and three-phase half-bridge inverter motor drives for appliances such as fans and refrigerator compressors
  • Propagation delays for the high- and low-side power FredFET devices are matched for better synchronization of switching characteristics and lower power dissipation
  •  Can operate up to a maximum input voltage rating of 500 V up to 150 °C
  • Isolation ratings up to 1500 Vrms/min.
  • Enables shorter inter-component connections, reducing unwanted EMI emissions. ESD protection is included on all leads
  • Bootstrap diode for the high-side driver section is integrated into the IR3103
  • A single-polarity power supply is all that is needed to drive the internal circuitry, simplifying module use
