IR Introduces Three-Phase Gate Driver IC with Integrated Operational Amplifier and Bootstrap Functionality for Motor Drive Applications
International Rectifier, IR® (NYSE: IRF), a world leader in power management technology has introduced the IRS233x(D) family of three-phase gate driver ICs for low-, mid-, and high-voltage motor drive applications including permanent magnet (PM) motor drives for air conditioners, washing machines, pumps and fans, and micro, mini and general purpose inverter drives.
The IRS233x(D) is a high-voltage, high speed power MOSFET and IGBT three-phase bridge- driver with referenced output channels to provide 200 mA/420 mA drive current at up to 20 V MOS gate drive capability operating up to 600 V. The new devices feature an integrated ground-referenced operational amplifier to provide analog feedback of the bridge current via an external current sense resistor and optional integrated bootstrap diode to reduce external part count and reduce PCB size.
“With its high level of integration, including an operational amplifier and bootstrap diode, the IRS233x(D) family simplifies and shrinks motor drive design while providing a high level of reliability and ruggedness,” said Henning Hauenstein, IR’s vice president Product Marketing, Automotive, Appliance and Industrial Motion.
