Protected Three-Phase 600V IC Featuring Extra Channel for PFC or Brake and Ground Fault Protection
International Rectifier introduced the IRS26302D protected 600V three-phase gate driver IC with ground fault protection. The IC has a seventh gate drive channel for a power factor correction (PFC) switch or inverter brake, making it well-suited to medium power appliance motor control and many other general-purpose three-phase inverter applications. The controller integrates power MOSFET/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 20V MOS gate drive capability operating up to 600V. An additional low-side driver is provided for a PFC switch or inverter brake. The IC incorporates negative Vs immunity circuitry to protect the system from catastrophic events that can be seen during high-current switching and short-circuit conditions in addition to ground fault protection, critical features for industrial systems that require high levels of robustness and reliability. Also, an advanced input filter has been integrated to reject noise and reduce distortion, improving system performance in many motor control applications.
