Three-phase gate driver

6 August 2008 Power Electronics / Power Management

New from International Rectifier is a rugged 600 V three-phase gate driver IC for low, mid-, and high-voltage motor drive applications including permanent magnet motor drives for appliances, industrial drives, micro inverter drives and electric vehicle drives. The IRS26310DJPbF integrates power MOSFET and IGBT gate drivers with three high-side and three low-side referenced output channels to provide 200 mA/350 mA drive current at up to 20 V MOS gate drive capability operating up to 600 V. The new IC incorporates an integrated bootstrap diode and offers a comprehensive set of protection features including improved negative voltage spike immunity to protect the system from catastrophic events seen during high-current switching and short-circuit conditions, to achieve high levels of robustness and reliability. An advanced input filter is also integrated to reject noise and reduce distortion to improve system performance.
