C0044BG400 - IGBT Gate Driver

General Description

Start up behavior An un-powered gate driver applies impedance to the gate

emitter connection as follows: - Permanent 20kΩ passive resistance (plus possible 20kΩ parallel on “IGBT Interface Board”) - Low impedance by discharged supply capacitors and main amplifier freewheeling diodes.

Key Features

  • High reliability topology.
  • Separate gate interface card for optimal packaging.
  • Designed for ultra low power consumption.
  • Balanced supply current in ON and OFF mode.
  • Build in DC/DC-converter with soft start.
  • Integrated input filter for low EMI.
  • Separate low impedance path for parasitic EMI currents.
  • PD-Voltage levels available up to 7kV.
  • Low impedance from gate to emitter at start-up and power fail.
  • Monitor.
