IR22381QPBF - 3-PHASE AC MOTOR CONTROLLER IC

Description

The IR22381Q and IR21381Q are high voltage, 3-phase IGBT driver best suited for AC motor drive applications.

Integrated desaturation logic provides all mode of overcurrent protection, including ground fault protection.

The sensing desaturation input is provided by active bias stage to reject noise.

Features

  • Floating channel up to +600V or +1200V “soft” over-current shutdown turns off desaturated output Integrated desaturation circuit Active biasing on sensing desaturation input Two stage turn on output for di/dt control Integrated brake IGBT driver with protection Voltage feedback sensing function Separate pull-up/pull-down output drive pins Matched delay outputs Under voltage loc.
