1200 V, 0.35 A / 0.54 A three-phase gate driver with integrated DESAT, Soft-Off, UVLO, TLTO, deadtime, brake chopper, and fault reporting

EiceDRIVER™ 1200 V three-phase gate driver with typical 0.35 A source and 0.54 A sink currents in MQFP-64 lead package for IGBTs and IGBT modules.

IR2238Q utilizes proprietary 1200 V HVIC and latch immune CMOS technologies which enable a rugged, monolithic construction with integrated protective features such as desaturation detection (DESAT), soft over-current shutdown (Soft-off), under-voltage lockout (UVLO) protection, two-level turn-on (TLTO) output, deadtime, and fault reporting.

The IR2238Q three-phase gate driver is well suited for low- and medium- power designs up to 6 kW or higher power levels with additional external buffer current driver. IR2238Q provides high performance drive capability with full protective features for a cost-competitive solution.

IR2238Q belongs to the1200 V level-shift junction isolated (JI)gate driver family.

优势

  • our monolithic high-voltage technology allows IR2238Q to safely drive 110Vac to 380Vac applications and can withstand up to 1200V dc voltage.
  • Desaturation detection of the power switch is fully integrated, resulting in increased system reliability, part reduction, and layout space savings.
  • Voltage feedback for dead time optimization
  • Two-stage turn on output for di/dt control
  • Under-voltage lockout provides protection at low supply voltage
  • Two separate channels allows safe inverter control from the anti-shoot-through input circuit.
  • In multi-phase systems, a dedicated local network properly manages phase-to-phase short circuits
