IR2238Q - 3-PHASE AC Motor Controller

Description

The IR2238Q is a 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.

Features

  • 3-PHASE AC Motor Controller IC.
  • Floating channel up to +1200V.
  • “soft” over-current shutdown turns off output.
  • Integrated desaturation circuit.
  • 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 lockout with hysteresis band.
  • Programmable deadtime.
